Description

CA Patent Application Blakes Ref: 11053/00008 REMOTE FUNCTION CONTROL SYSTEM FOR A VEHICLE HAVING A DATA
COMMUNICATIONS BUS AND RELATED METHODS
Field of the Invention [0001] The present invention relates to the field of vehicle control systems and, more particularly, to a remote function control system and related methods for vehicles.
Background of the Invention

[0002] Vehicle security systems are widely used to deter vehicle theft, prevent theft of valuables from a vehicle, deter vandalism, and to protect vehicle owners and occupants.
A typical automobile security system, for example, includes a central processor or controller connected to a plurality of vehicle sensors. The sensors, for example, may detect opening of the trunk, hood, doors, windows, and also movement of the vehicle or within the vehicle.
Ultrasonic and microwave motion detectors, vibration sensors, sound discriminators, differential pressure sensors, and switches may be used as sensors. In addition, radar sensors may be used to monitor the area proximate the vehicle.

[0003] The controller typically operates to give an alarm indication in the event of triggering of a vehicle sensor. The alarm indication may typically be a flashing of the lights and/or the sounding of the vehicle horn or a siren. In addition, the vehicle fuel supply and/or ignition power may be selectively disabled based upon an alarm condition.

[0004] A typical security system also includes a receiver associated with the controller that cooperates with one or more remote transmitters typically carried by the user as disclosed, for example, in U.S. Pat. No. 4,383,242 to Sassover et al. and U.S. Pat. No.

5,146,215 to Drori.
The remote transmitter may be used to arm and disarm the vehicle security system or provide other remote control features from a predetermined range away from the vehicle. Also related to remote control of a vehicle function U.S. Pat. No. 5,252,966 to Lambropoulous et at. discloses a remote keyless entry system for a vehicle. The keyless entry system permits the user to remotely open the vehicle doors or open the vehicle trunk using a small handheld transmitter.
[0005] Unfortunately, the majority of vehicle security systems need to be directly connected by wires to individual vehicle devices, such as the vehicle horn or door switches of the vehicle. In other words, a conventional vehicle security system is hardwired to various vehicle components, = 1 23087033.2 CA Patent Application Blakes Ref: 11053/00008 typically by splicing into vehicle wiring harnesses or via interposing T-harnesses and connectors. The number of electrical devices in a vehicle has increased so that the size and complexity of wiring harnesses has also increased. For example, the steering wheel may include horn switches, an airbag, turn-signal and headlight switches, wiper controls, cruise control switches, ignition wiring, an emergency flasher switch, and/or radio controls. Likewise, a door of a vehicle, for example, may include window controls, locks, outside mirror switches, and/or door-panel light switches.

[0006] In response to the increased wiring complexity and costs, vehicle manufacturers have begun attempts to reduce the amount of wiring within vehicles to reduce weight, reduce wire routing problems, decrease costs, and reduce complications which may arise when troubleshooting the electrical system. For example, some manufacturers have adopted multiplexing schemes to reduce cables to three or four wires and to simplify the exchange of data among the various onboard electronic systems as disclosed, for example, in "The Thick and Thin of Car Cabling" by Thompson appearing in the IEEE Spectrum, February 1996, pp. 42-45.

[0007] Implementing multiplexing concepts in vehicles in a cost-effective and reliable manner may not be easy. Successful implementation, for example, may require the development of low or error-free communications in what can be harsh vehicle environments. With multiplexing technology, the various electronic modules or devices may be linked by a single signal wire in a bus also containing a power wire, and one or more ground wires. Digital messages are communicated to all modules over the data communications bus. Each message may have one or more addresses associated with it so that the devices can recognize which messages to ignore and which messages to respond to or read.

[0008] The Thompson article describes a number of multiplexed networks for vehicles. In particular, the Grand Cherokee made by Chrysler is described as having five multiplex nodes or controllers: the engine controller, the temperature controller, the airbag controller, the theft alarm, and the overhead console. Other nodes for different vehicles may include a transmission controller, a trip computer, an instrument cluster controller, an antilock braking controller, an active suspension controller, and a body controller for devices in the passenger compartment.

23087033.2 CA Patent Application Blakes Ref: 11053/00008

[0009] A number of patent references are also directed to digital or multiplex communications networks or circuits, such as may be used in a vehicle. For example, U.S. Pat.
No. 4,538,262 Sinniger et al. discloses a multiplex bus system including a master control unit and a plurality of receiver-transmitter units connected thereto. Similarly, U.S. Pat. No.
4,055,772 to Leung discloses a power bus in a vehicle controlled by a low current digitally coded communications system. Other references disclosing various vehicle multiplex control systems include, for example, U.S. Pat. No. 4,760,275 to Sato et al.; U.S. Pat. No. 4,697,092 to Roggendorf et al.;
and U.S. Pat. No. 4,792,783 to Burgess et al.

[0010] Several standards have been proposed for vehicle multiplex networks including, for example, the Society of Automotive Engineers "Surface Vehicle Standard, Class B Data Communications Network Interface", SAE J1850, July 1995. Another report by the SAE is the "Surface Vehicle Information Report, Chrysler Sensor and Control (CSC) Bus Multiplexing Network for Class 'A' Applications", SAE J2058, July 1990. Many other networks are also being implemented or proposed for communications between vehicle devices and nodes or controllers.

[0011] Unfortunately, conventional vehicle control systems, such as aftermarket vehicle security = systems, are for hardwired connection to vehicle devices and are not readily adaptable to a vehicle including a data communications bus. Moreover, a vehicle security system if adapted for a communications bus and devices for one particular model, model year, and manufacturer, may not be compatible with any other models, model years, or manufacturers.
Other systems for the control of vehicle functions may also suffer from such shortcomings.

[0012] One approach to addressing these shortcomings is described in U.S.
Patent No.
6,011,460 to Flick which discloses a multi-vehicle security system. More particularly, the Flick 460 patent discloses a desired signal enabling circuit electrically coupled to the data communications bus for enabling an alarm controller to operate using a set of desired signals for a desired vehicle from among a plurality of possible sets of signals for different vehicles.
Thus, the desired signal enabling circuit permits the alarm controller to communicate with a vehicle security sensor and an alarm indicator via the data communications bus so that the alarm controller is capable of operating the alarm indicator responsive to the vehicle security sensor. The desired signal enabling circuit may learn the desired set of signals from the 23087033.2 CA Patent Appfication Blakes Ref: 11053/00008 plurality of different sets of signals for different vehicles by connection and communications with a downloading device, such as a portable or laptop computer.

[0013] However, still further improvements for remote control device operation of vehicle devices, for example, a security system, remote start system, etc., may be desired. In -particular, it may desirable to more easily configure or adapt a wider range of vehicle devices to be operated from a remote control device.

The remote function device 20' can be configured to change or set the protocol of the data communications bus 15', the vehicle device bus codes, and the protocol of the second and third wireless devices 21', 22'. For example, the remote function device 20' may request one or more of the vehicle identification number (VIN), the mileage, and fuel level of the vehicle via data communications bus 15' using a first protocol. If a response to the request is received, the correct protocol has been selected. Otherwise, the remote function device 20' may select another protocol and make another request using the newly selected protocol. The process may be repeated until a response is received. The remote function device 20' may also 23087033.2 CA Patent Application Blakes Ref. 11053/00008 be programmed to selectively enable features of the controller 23', as will be appreciated by those skilled in the art. Further details regarding a multi-vehicle compatible controller are disclosed in U.S. Patent Nos. 5,719,551 and 6,011,460 to Flick, for example.

[0043] To program the multi-vehicle compatible controller 23', the remote function device 20' may include a downloading interface 27' coupled to the controller to permit downloading a configuration of the controller. The downloading interface 27' may be a wired interface for coupling to a programming device, for example, a laptop or tablet computer.
Programming or configuration, as noted above, may be performed via downloading from the programming device to the remote function device 20'. Of course, the downloading interface 27' may be a wireless interface, for example, so that the multi-vehicle compatible controller 23' may be configured or programmed wirelessly, via the Internet or cellular connection, from a programming device. The multi-vehicle compatible controller 23' may be programmed or configured within the vehicle or may be removed from the vehicle for programming. Further details of programming a multi-vehicle compatible controller 23' may be found in U.S. Patent No. 8,032,278 to Flick, assigned to the present assignee. Other or additional programming or configuration techniques may be used, as will be appreciated by those skilled in the art.

[0044] The remote function device 20' may further include a learning interface 26' coupled to the multi-vehicle compatible controller 23' to permit learning a configuration of the controller. For example, new or unrecognized configuration parameters, particularly, data bus or communications codes, may be learned as they are communicated, and thereafter stored in the memory 33'. Other or additional learning techniques may be used, as will be appreciated by those skilled in the art. The downloading interface 27' and the learning interface 26' may be particularly useful with the multi-vehicle compatible controller 23' for downloading and learning the vehicle device bus codes and protocols.

[0045] Referring now additionally to FIG. 3, in yet another embodiment, the controller 23" is a multi-vehicle compatible controller that is operable with different vehicles using different wireless communications protocols and/or codes of the first wireless communications device 13". For example, the multi-vehicle compatible controller 23" may be operable with different vehicles using Bluetooth and/or WLAN protocols and/or associated codes of the first wireless communications device 13".

A learning interface 26" is also coupled to the multi-vehicle compatible controller 23" to permit learning a configuration of the controller with respect to the communications codes and/or protocols of the first wireless device 13".

[0046] Referring now additionally to FIG. 4, in yet another embodiment, the remote function device 20" includes a vehicle position determining device 24m, for example, a global positioning system (GPS) receiver, coupled to a tracking controller 23". The tracking controller is for performing a tracking function based upon the vehicle location, for example, for which may be used to determine a vehicle condition or status, i.e., stolen. Vehicle device functions may be controlled by the tracking controller 23' based upon the vehicle position. Further details of a vehicle tracking unit for controlling operable vehicle devices using a data communications bus are disclosed in U.S. Patent No. 6,924,750, assigned to the present assignee.

Patent No. 6,812,829, assigned to the present assignee. For example, the remote control device 30" may cooperate with the remote start controller 23" to wirelessly communicate with a starter vehicle device and/or fuel supply system coupled to the vehicle data bus 15", to thus start the vehicle 35".

[0048] Referring now additionally to FIG. 6, in some embodiments, the controller 123 may be a security controller for performing a security function. For example, the remote control device 130 may cooperate with the security controller 123 to communicate with or activate a vehicle device 116a-116n, for example, a motion sensor, coupled to the vehicle data bus 115.
As another example, the security controller 123 may communicate with the door locks coupled to the data communications bus 115 to send a door lock status to the remote control device 130. The security controller 123 may also send a vehicle device status, such as, for example, an alarm condition to the remote control device 130.

[0049] Referring now additionally to FIG. 7, the controller 123' may be a remote keyless entry controller for performing at least one remote keyless entry function. For example, the remote keyless entry controller 123' may permit communication from the remote control device 130' for 23087033.2 CA Patent Application Blakes Ref- 11053/00008 unlocking the door locks. The remote control device 130' may also cooperate via the remote keyless entry controller 123' to lock the doors of the vehicle 134'.

[0050] Referring now additionally to FIG. 8, the controller 123" may be a diagnostic controller for performing at least one diagnostic function. For example, the diagnostic controller 123" may permit communication for determining vehicle fault codes and communicating those codes to the remote control device 130". The remote control device 130" may be a portable computer, laptop or tablet, for example, and may wirelessly receive the vehicle fault codes. Diagnostic codes, for example, device reset codes, may be wirelessly sent from the portable computer 130" to one or more vehicle devices 116a"-116n" via the diagnostic controller 123".

[0051] Of course, while the controller 23 has been described in several examples, it should be understood that the controller may be more than one type of controller and configured to perform any one or more of the above-noted functions. Additional functions may be performed by the controller 23 as will be appreciated by those skilled in the art. For example, the controller 23 may be a climate controller and perform a climate controlling function, such as, changing the cabin temperature and fan speed.

[0056] A controller 223 is coupled to the second and third wireless devices, similar to the controllers discussed above. The controller 223 may advantageously receive updated vehicle device bus codes from the remote control device 230 to cause one or more of the vehicle 23087033.2 CA Patent Application Blakes Ref: 11053/00008 devices 216a-216n to perform a new vehicle operation which had previously been "unlearned"
to the wireless databus device 213, at Block 304, and wirelessly transmit the updated data bus codes to the wireless data bus device 211 to be stored in the memory 231, at Block 305, which illustratively concludes the method illustrated in FIG. 12 (Block 306).

[0057] More particularly, the remote function device 220 may advantageously be used to update the wireless databus device 213 for performing new operations that were not provided or available at the time of purchase of the vehicle 234. By way of example, if the vehicle 234 has a convertible top, one (or more) of the vehicle devices 216a-216n may be an actuator for raising and lowering the convertible top. As such, the updated data bus codes may be for causing the appropriate vehicle device(s) 216a-216n to raise and lower the convertible top. In accordance with a similar example, one or more of the vehicle devices 216a-216n may be vehicle window actuators, in which case the updated data bus codes may be for causing the window actuator(s) to raise and lower windows in the vehicle 234, as will be appreciated by those skilled in the art.

[0058] In yet another example, the updated data bus codes may be for causing one or more of the vehicle devices 216a-216n to perform a vehicle remote start operation, as discussed further above. In some implementations, the remote function device 220 may be coupled to a separate data bus (not shown) extending throughout the vehicle 234, such as an on-board diagnostics (OBD) bus with an OBD-II connection port, for example. In cases where vehicle devices other than the vehicle devices 216a-216n connected to the data communications bus 215 are required to help perform a remote start (or other) operation, the controller 223 may advantageously cooperate with the wireless data bus device 211 to control the other device(s) via the OBD (or other) data bus, while the wireless data bus device 211 controls the requisite vehicle devices 216a-216n, as will be appreciated those skilled in the art.

[0059] Furthermore, the remote function device 220 may be removably connectable or coupled to the vehicle, so that it may be removed and replaced in the vehicle if desired, or moved between vehicles. For example, the remote function device may be removably connectable to the wired vehicle electrical power system 218. In the above-noted example where the remote function device 220 connects to the OBD bus, this may be done via a removable connection to the OBD-II connection port, for example.

[0060] It should be noted that updated vehicle device bus codes for other vehicle devices 216a-216n besides those discussed above may be used in different embodiments. This approach may advantageously allow users to remotely control the newly added operations (e.g., convertible top, windows, remote starting, etc.) via an app installed on a smartphone, via a Web interface on a computer, etc., as will be appreciated by those skilled in the art.

[0061] Many modifications and other embodiments of the invention will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is understood that the invention is not to be limited to the specific embodiments disclosed, and that modifications and embodiments are intended to be included within the scope of the appended claims.
