BACKGROUND

This disclosure relates generally to a method and system for modifying or altering factory vehicle electronic communications to or from factory sensors or signals, or other components, by way of the addition of aftermarket components, such as a relocated vehicle sensor, or an aftermarket breakout device in electrical communication with one or more vehicle control modules, and then altering those communications, for example, to relocate a factory vehicle sensor reading to use a sensor or signal in a different location within the vehicle.

Since at least model year 1996, every new passenger car and light-duty truck sold in the United States has had a computer diagnostic data connection port, such as an OBD1, OBD2/OBD-II, or SAE-J1962 port. Most heavy-duty trucks currently sold in the United States also include a computer diagnostic port, usually referred to as a J1708 port or a J1939 port. Some vehicles also include one or more additional data ports, sometimes located in the passenger compartment, the trunk, or the engine bay. These data ports permit a mechanic, vehicle operator, or other user to connect to the vehicle and retrieve vehicle diagnostic data and operating parameters, that is, data about the vehicle, including engine, fuel system, brake system, and other data, including various sensor signals.

Modern vehicles typically utilize many vehicle protocol data buses, some of which may be accessible via data ports. A vehicle protocol data bus that is not accessible via a data port (and thus would require hard-wiring, splicing, soldering, Y or T-harness, or other means of direct wired connection) is typically referred to as an isolated vehicle protocol data bus. In some vehicles, the manufacturer may incorporate gateway modules (that is, an electronic vehicle control module that can simultaneously communicate or act as a “gateway” between at least two different vehicle protocol data buses) to ensure that certain data is available to vehicle electronic control modules on other vehicle protocol data buses. These vehicle protocol data buses typically utilize CAN, J1850, ISO 9141, ISO 14230, KWP2000, ALDL, UART based, LIN, SENT, MOST, FlexRay, Ethernet, or some other communications protocol (or variant) as is known in the art.

Many companies also manufacture aftermarket flashing or tuning products that reprogram the vehicle engine control module with different calibrations, tables, curves, and other operating parameters such as spark or timing, fuel settings, shift points, temperature conditions, and other operating parameters and settings. Most systems of this kind are primarily designed to produce more horsepower, but some are advertised as useful to improve fuel economy or other aspects of the vehicle.

Often companies or consumers may make changes or modifications to their vehicle that require adding, removing, or adjusting vehicle parameters, signals, or other sensor data. These adjustments may be required to correct signals or data, to improve or correct the manner in which the engine controls operate. Sometimes these changes are made in conjunction with a new vehicle control module calibration (or flash/tune).

Some companies manufacture aftermarket supercharger or turbocharger kits, commonly requiring relocation (or “breakout”) of factory sensors or signals to improve or correct readings that may differ after the addition of the aftermarket items. For example, when adding a supercharger, it is common to relocate the intake air temperature sensor signal (commonly known as IAT), from within the factory mass air flow or multifunction air sensor (generally in or near the airbox, where air will be colder) to a location after the supercharger compressor (or intercooler, if equipped), as the compressed intake air is typically much hotter before it actually enters the engine. Relocation of the IAT signal in this case restores accurate temperature readings to the factory vehicle control module, improving air density calculations, and thus vehicle emissions and ignition timing and control.

In the past, a new sensor could be installed simply by running the existing sensor harness to a new location, or re-routing a single signal wire from an existing sensor to a new location or new sensor. This often also required calibration of the vehicle control module receiving communication from this sensor, to correct the readings to be appropriate and accurate for the new type of sensor that has been installed.

Many modern vehicles have multifunction sensors, which combine multiple sensors or functions into a single unit, and are usually digital in nature (as opposed to analog sensors), and typically communicate with each other or with a vehicle control module using an isolated vehicle protocol data bus (such as LIN, SENT, UART, etc.) containing information from multiple types of sensors or signals on a single bus—often contained to just a single wire. This can save cost on manufacturing the vehicle, and may simplify assembly, installation, or servicing of these sensors or systems. With such digital multifunction sensors, unfortunately it is often no longer possible to reroute a single wire to correct or alter a single signal value as has been done in the past.

SUMMARY

The present disclosure provides an aftermarket breakout device that is attached to, connected to, plugged into, or in electrical communication with, one or more factory vehicle sensors, vehicle control modules, or relocated vehicle sensors. In a typical embodiment, the present breakout device is in electrical communication with a single vehicle control module, a single factory vehicle sensor, and a single additional relocated sensor. In such an embodiment, the breakout device intercepts the communications from the factory vehicle sensor, modifies those communications using signal data from the relocated vehicle sensor, and transmits the modified communications to the vehicle control module, such that the factory vehicle control module is not aware that it is not communicating with the original factory sensor. In some embodiments, the breakout device modifies only a portion of the communications, and may retransmit the remaining communications un-modified as required.

The present breakout device communicates using various protocols and signal levels, including, in some embodiments, a voltage signal, an amperage signal, a resistance signal, a frequency signal, an RF signal, an SPI protocol, an I2C protocol, a UART protocol, a J1850 protocol, a CAN protocol, a SENT protocol, a LIN protocol, a MOST protocol, or an Ethernet protocol. While monitoring an additional relocated sensor, or potentially other vehicle operating parameters or conditions, the present device can send communications, signals, or commands to a vehicle control module in place of a factory vehicle sensor.

The breakout device is designed to be used full time while the vehicle is operating and stays in constant communication with the factory vehicle systems. In some embodiments, the factory vehicle systems are not even aware that the aftermarket breakout device has replaced or altered communications, or that sensor or signal readings have been relocated.

The breakout device may include predetermined vehicle operating parameter limits and also permit the user to configure those limits or additional vehicle operating parameters or limits. The device then monitors the vehicle operating parameters and when a predetermined or pre-configured limit is exceeded, the breakout device may further modify communications or commands to the factory vehicle control module to create a desired change or correction in vehicle operating behavior. The breakout device may also include one or more peripheral input ports to acquire other data that can then be monitored and used as a configured limit. The breakout device may also include one or more peripheral output ports that enable voltage or communications signals to be output to another peripheral device or system, or even to another aftermarket vehicle component. The breakout device may include wireless and wired connections (such as USB, Bluetooth, WiFi, etc.) to allow the vehicle operator (or other user) to interface with a computer or mobile device, and perform data logging or configure the breakout device to customize features, settings, options, limits, or operating parameters.

DETAILED DESCRIPTION

Modern vehicles typically have multiple vehicle systems with protocol data buses, some of which may be isolated, and at least one data port, such as an On-Board Diagnostics II port (“OBD-II port”). These data buses and data ports are used to communicate with the on-board electronic and diagnostics system of the vehicle, typically using a computing device or specialized hand-held OBD-II diagnostic appliance. According to the present disclosure, an aftermarket device communicates with one or more factory vehicle systems, sensors, or vehicle control modules, and one or more aftermarket relocated vehicle sensors, by way of being hard-wired, spliced, soldered, or other means of direct wired connection to a vehicle protocol data bus or communications or signal wire. In some embodiments, wireless communications protocols may be used for some or all of these communications. The breakout device monitors the vehicle operating parameters and conditions and modifies sensor readings or signals during communications with factory vehicle components.

Modern vehicles come equipped with numerous sensors and actuators. Many vehicles are starting to use “digital” sensors that communicate with a vehicle control module using an isolated vehicle protocol bus (such as LIN, SENT, CAN, etc), as opposed to a simple 0-5 Volt signal reading traditionally used (which generally used a single wire for only one reading). Examples include oil pressure sensors, oil temperature sensors, oil level sensors, mass air flow sensors, air pressure sensors, air temperature sensors, suspension height sensors, accelerometers, gyroscopes, fuel pressure sensors, and others.

These digital sensors can sometimes share a single housing, and often a single communication wire, for multiple different sensors or readings. This makes it difficult to alter signals, relocate or move a sensor, or correct sensor readings after the vehicle has been modified in a way where this would be beneficial or required. An example of this is an air sensor that combines readings for mass air flow, air humidity, air pressure, and air temperature into a single housing with a single communication wire.

A typical vehicle control module and sensor configuration is depicted in FIG. 1, on a four cylinder engine 11. The vehicle 7 depicted is naturally aspirated, with air flowing through an air filter 16, then a throttle body 18, before flowing through an intake manifold 17 and entering the engine 11. A combined air sensor 9 reads the mass, pressure, and temperature of the incoming air and reports this to the factory vehicle control module 10; this works well in this configuration because the air does not significantly change temperature between the sensor 9 location and entering the engine 11.

FIG. 2 depicts a vehicle 7 modified with an aftermarket supercharger assembly 12. The compressed intake air flowing from the supercharger assembly 12 is typically much hotter than the uncompressed air at the location of the combined air sensor 9, where the air temperature was measured and reported to the factory vehicle control module 10. As a result, the air sensor 9 is not providing the modified vehicle (with the supercharger 12) with accurate data.

As depicted in FIG. 3, a breakout device 6 typically includes various communications ports and connectors. For example, the breakout device 6 has a connector 3 that plugs into the original factory harness of the vehicle where a sensor has been disconnected, to allow the device 6 to be in electrical communication with the factory vehicle control module 10. The device 6 may also include a connector 4 that would attach to the original factory sensor 9, especially in embodiments where only a portion of the original sensor communications should be altered.

The present device 6 also allows a connector 5 to be used to attach a relocated aftermarket sensor 13 (see FIG. 4). In this embodiment, the device 6 may use readings from this sensor 13 to alter the communications from the factory vehicle sensor 9 to the vehicle control module 10. In other embodiments, the device 6 does not use a relocated vehicle sensor. The device may alter or generate communications based on various other factory sensor readings, user calculations, or other parameters.

As depicted in FIG. 4, according to one embodiment, the device 6 is connected between the factory vehicle control module 10 and the factory sensor 9 so that the factory signal readings, and other electrical communications, may be intercepted and modified by the device 6 before being received by the factory vehicle control module 10 and the factory sensor 9. In other embodiments, the factory sensor 9 is completely removed and the device 6 generates factory signal readings, and other electrical communications, which are received by the factory vehicle control module 10. Typically these generated factory signals are based on one or more relocated vehicle sensors or other factory sensor readings, user calculations, or other parameters. In this manner, the aftermarket breakout device 6 is able to simulate signal readings in place of the factory sensor 9 even though that sensor has been removed. In effect, the aftermarket breakout device 6 has become a multifunction sensor in this embodiment.

In typical embodiments, the factory, relocated, and generated signal readings, and corresponding electrical communications, comprise a pressure signal, a temperature signal, a humidity signal, a voltage signal, a speed signal, a position signal, a ratio signal, a percentage signal, a current/amperage signal, a resistance signal, a frequency signal, or other signal type.

According to one embodiment, the device 6 is connected between the factory vehicle control module 10 and a digital multifunction factory sensor 9 utilizing a digital protocol such as LIN (but could be CAN, SENT, or another digital protocol as is known in the art) to transmit or receive sensor and signal data, as well as unique identifiers, headers, counters, checksums, or other data, within separate digital protocol message frames. These message frames, containing signal readings or other communications, use unique message identifiers, usually defined using hexadecimal notation. For example, the hexadecimal value 10 (which is sometimes written as 0x10 or $10) would refer to the decimal number 16. Similarly, the hexadecimal values of 2A and 2B would refer to the decimal numbers 42 and 43 respectively. In one exemplary embodiment, the device 6 utilizes a unique message identifier hexadecimal 2A for digital protocol messages containing a throttle inlet pressure reading, a barometric pressure reading, a compressor inlet pressure reading, a manifold pressure reading, or a rolling counter, some of which have been modified using data values obtained from relocated sensor signal readings. Also in this exemplary embodiment, the device 6 utilizes unique message identifier hexadecimal 2B for digital protocol messages containing a intake air temperature reading, a humidity reading, or a rolling counter, some of which have been modified using data values obtained from relocated sensor signal readings

In some embodiments, the factory vehicle control module 10 transmits the beginning of a digital protocol message frame, containing the unique identifier, and the device 6 transmits the remainder of the digital protocol message containing data, such as intake air temperature and barometric pressure, based on relocated sensor readings.

In most embodiments, the factory vehicle control module 10 is an Electronic Control Unit (“ECU”), which is an Engine Control Module, a Transmission Control Module, a Motor Control Module, a Fuel Control Module, an Injector Control Module, a Boost Control Module, a Battery Control Module, a Generator Control Module, a Brake Control Module, a Traction Control Module, a Stability Control Module, a Safety Control Module, a Body Control Module, a Chassis Control Module, or other vehicle control module type.

According to one embodiment, the device 6 is disconnected from the vehicle harness 12 and connected to a computer, laptop, smartphone, or tablet by way of the USB port on the device 6 or special USB harness attached to the device 6. According to other embodiments, the device 6 has wireless capability, or has a long communications cable 16, and thus need not be disconnected from the vehicle harness. After connecting the device 6 to a computer, laptop, smartphone, or tablet using a USB port or other communications method, the user may configure the device to accept various factory or relocated sensor configurations or data alterations. The device is then plugged back into the vehicle harness, where it operates using the updated configuration.

In some embodiments, the user may configure the device 6 to perform custom calculations, formulas, or algorithms to generate new data based on existing vehicle or peripheral input data. This new data can be additional to factory sensor data, can be used in place of factory sensor data, or can alter only a portion of factory sensor data.

In some embodiments, the device 6 can be removed from the vehicle and connected to an external computer (such as a desktop, laptop, tablet, smartphone, or other computing apparatus) for configuration purposes. One way to configure the device 6 involves connecting the device 6 to a laptop computer by way of a USB cable. Using these connection methods, a user may enter configuration information into, for example, an application running on the laptop, and the device 6 is then updated with the new configuration by passing the instructions over the USB cable.

In other embodiments, the device 6 can remain connected to the vehicle and concurrently connected to such a computer for configuration purposes. Typically, but not necessarily, the device 6 stops monitoring, communicating, or commanding the vehicle or aftermarket vehicle components while connected to such a computer. In other embodiments, the device 6 is configured with either a wired or wireless connection, thereby allowing that computer to communicate with the device 6 or the vehicle in a bidirectional manner.

The device 6 may include peripheral input ports or harness connectors for obtaining data from external sources. Data from these external sources may be configured or used to further modify electrical communications to a factory vehicle control module 10. In some embodiments, these external sources may control communications in their entirety.

In one embodiment, the device 6 connects to multiple separate, distinct, and different communications systems (or data buses) on the vehicle data, typically using differing pins on a vehicle harness connector, or separate vehicle harness connectors completely. The device 6 may then send communications to, and read vehicle operating parameters and conditions from, multiple vehicle electronic control modules or sensors across several data buses 15. The device can then alter these communications as required according to the device's current configuration and relocated sensor attachments.

In some embodiments, the device 6 allows the vehicle operator or other user to introduce new data by way of custom calculations using vehicle operating parameters, or vehicle condition data obtained from a vehicle data port 14 as well as sensor readings or other data obtained using sensors on the device itself or from a peripheral port or harness connector. The device 6 allows a vehicle operator or other user to further configure the device 6 operation or behavior using this new data.

As depicted in FIG. 5, in some embodiments the vehicle 7 may incorporate multiple vehicle protocol data buses 15, gateway modules 10, body control modules 10, chassis control modules 10, engine and/or transmission control modules 10, or other vehicle electronic control modules 10. Some of those vehicle protocol data buses 15 may be isolated vehicle protocol data buses, while others may be accessible through a data port 14. As depicted in FIG. 5, typically the gateway module 10 connects to the data port 14 through the data buses 15, but other configurations are also possible. The breakout device 6 may connect to a single data bus, or a multitude of data buses, to or from various modules or sensors to read vehicle operating parameters.

Thus, the present system has several advantages over the prior art. Although the foregoing description contains many specifics, these are not to be construed as limiting the scope of the present disclosure, but merely as providing certain embodiments. Similarly, other embodiments of the invention may be devised that do not depart from the scope of the present disclosure. For example, features described herein with reference to one embodiment also may be provided in others of the embodiments described herein. The scope of the invention is, therefore, indicated and limited only by the appended claims and their legal equivalents, rather than by the foregoing description. All additions, deletions, and modifications to the invention, as disclosed herein, which fall within the meaning and scope of the claims, are encompassed by the present invention.
