Abstract

Drive-by-wireless vehicle control techniques use a wireless connection between a sensor module and a control module. An action by the driver of the vehicle is detected by the sensor module and communicated to the control module using a message sent using a wireless communication pathway. The control module directs the appropriate vehicle component based on the wireless message received. The vehicle identification number (VIN) that uniquely identifies the vehicle is used to identify a wireless message has been sent from a sensor module that is part of the vehicle. The use of the VIN to identify a wireless message that applies to a particular vehicle that has been assigned the same VIN may help ensure that the particular vehicle is directed only based on actions by the driver of the particular vehicle.

Claims

1. A method for controlling a component in a vehicle, the method comprising:

detecting a control action in a vehicle;

sending a message using a wireless communication pathway, the message describing the detected control action and including a vehicle identification number;

receiving the message;

determining whether the vehicle identification number included in the message matches a vehicle identification number of a vehicle at which the message is received; and

when the vehicle identification number matches, controlling a component of the vehicle based on the received message.

2. The method of claim 1 wherein:

detecting a control action comprises detecting an accelerator pedal being pressed, and

controlling a component of the vehicle comprises controlling a throttle of the vehicle.

3. The method of claim 1 wherein:

detecting a control action comprises detecting the turning of a steering wheel, and

controlling a component of the vehicle comprises controlling a steering mechanism of the vehicle.

4. The method of claim 1 wherein:

detecting a control action comprises detecting a brake pedal being pressed, and

controlling a component of the vehicle comprises controlling a hydraulic brake system of the vehicle.

5. The method of claim 1 further comprising sending an acknowledgment message using the wireless communication pathway, the acknowledgment message including the vehicle identification number of the vehicle.

6. The method of claim 1 further comprising:

determining whether the wireless communication pathway is operational; and

permitting the engine of the vehicle to be started or permitting the vehicle to be placed in gear only when the wireless communication pathway is operational.

7. A computer-readable medium or propagated signal having embodied thereon a computer program configured to control a component in a vehicle, the medium or signal comprising one or more code segments configured to:

detect a control action in a vehicle;

send a message using a wireless communication pathway, the message describing the detected control action and including a vehicle identification number;

receive the message;

determine whether the vehicle identification number included in the message matches a vehicle identification number of a vehicle at which the message is received; and

when the vehicle identification number matches, control a component of the vehicle based on the received message.

8. The medium or signal of claim 7 wherein:

detecting a control action comprises detecting an accelerator pedal being pressed, and

controlling a component of the vehicle comprises controlling a throttle of the vehicle.

9. The medium or signal of claim 7 wherein:

the one or more code segments configured to detect a control action comprises one or more code segments configured to detect the turning of a steering wheel, and

the one or more code segments configured to control a component of the vehicle comprises one or more code segments configured to control a steering mechanism of the vehicle.

10. The medium or signal of claim 7 wherein:

the one or more code segments configured to detect a control action comprises one or more code segments configured to detect a brake pedal being pressed, and

the one or more code segments configured to control a component of the vehicle comprises one or more code segments configured to control a hydraulic brake system of the vehicle.

11. The medium or signal of claim 7 further comprising one or more code segments configured to send an acknowledgment message using the wireless communication pathway, the acknowledgment message including the vehicle identification number of the vehicle.

12. The medium or signal of claim 7 further comprising one or more code segments configured to:

determine whether the wireless communication pathway is operational, and

permit the engine of the vehicle to be started or permit the vehicle to be placed in gear only when the wireless communication pathway is operational.

13. A system for controlling a component in a vehicle, the system comprising a control module wirelessly connected to one or more sensor modules and one or more vehicle components, wherein:

the one or more sensor modules include a wireless transmitter and are configured to;

detect a control action in a vehicle and,

send a first message using a wireless communication pathway, the message describing the detected control action and including a vehicle identification number;

the control module includes a wireless communication controller and a processor configured to;

receive the first message, determine whether the vehicle identification number included in the message matches a vehicle identification number of a vehicle at which the first message is received, and

when the vehicle identification number matches, send a second message using a second wireless communication pathway to one of the one or more vehicle components; and

the one or more vehicle components include a wireless receiver and are configured to;

receive the second message, and

control a component of the vehicle based on the received message.

14. The system of claim 13 wherein:

the one or more sensor modules configured to detect a control action comprise one or more sensor modules configured to detect an accelerator pedal being pressed, and

the one or more vehicle components configured to control a component of the vehicle comprises one or more vehicle components configured to control a throttle of the vehicle.

15. The system of claim 13 wherein:

the one or more sensor modules configured to detect a control action comprise one or more sensor modules configured to detect the turning of a steering wheel, and

the one or more vehicle components configured to control a component of the vehicle comprises one or more vehicle components configured to control a steering mechanism of the vehicle.

16. The system of claim 13 wherein:

the one or more sensor modules configured to detect a control action comprise one or more sensor modules configured to detect a brake pedal being pressed, and

the one or more vehicle components configured to control a component of the vehicle comprises one or more vehicle components configured to control a hydraulic brake system of the vehicle.

17. The system of claim 13 wherein:

the control module is further configured to send an acknowledgment message using the wireless communication pathway, the acknowledgment message including the vehicle identification number of the vehicle;

one or more of the one or more sensor modules include a wireless receiver and are configured to receive the acknowledgment message;

one or more of the one or more vehicle components include a transmitter and are further configured to send a second acknowledgment message using the wireless communication pathway, the acknowledgment message including the vehicle identification number of the vehicle; and

the control module is further configured to receive the second acknowledgment message.

18. The system of claim 13 wherein the control module is further configured to:

determine whether the wireless communication pathway is operational; and

permit the engine of the vehicle to be started or permit the vehicle to be placed in gear only when the wireless communication pathway is operational.

19. The system of claim 13 wherein the vehicle is an automobile, a bus, a truck, or a train.

20. A vehicle that includes the system of claim 13.
