Abstract

A tire pressure monitoring system electronic control unit for hands free operation of a trunk of a vehicle includes a receiver configured to receive pressure data transmitted from a tire pressure monitoring system sensor, and also include a vehicle controller area network interface configured to send a control signal to a body control module using a vehicle network. The tire pressure monitoring system electronic control unit further includes a control circuit configured to send the control signal to the body control module using the vehicle controller area network interface, wherein the control signal causes the body control module to open the trunk of the vehicle, and wherein the control circuit sends the control signal in response to determining, using the pressure data, that the tire of the vehicle has been kicked.

Claims

1. A tire pressure monitoring system electronic control unit for hands free operation of a trunk of a vehicle, comprising:

a receiver configured to receive pressure data transmitted from at least one tire pressure monitoring system sensor, wherein the tire pressure monitoring system sensor is configured to monitor the pressure within a tire of the vehicle;

a vehicle controller area network interface, wherein the vehicle controller area network interface is configured to send a control signal to a body control module using a vehicle network; and

a control circuit configured to send the control signal to the body control module using the vehicle controller area network interface,

wherein the control signal causes the body control module to open the trunk of the vehicle, and

wherein the control circuit sends the control signal in response to determining, using the pressure data, that the tire of the vehicle has been kicked.

2. The tire pressure monitoring system electronic control unit of claim 1, further comprising a transmitter configured to transmit a second control signal to the tire pressure monitoring system sensor, wherein the second control signal causes the tire pressure monitoring system sensor to exit a power saving mode and transmit pressure data.

3. The tire pressure monitoring system electronic control unit of claim 2, wherein the control circuit is configured to transmit the second control signal using the transmitter in response to determining that a key fob and a remote keyless entry system of the vehicle are in communication, wherein the control circuit determines that the key fob and the remote keyless entry system of the vehicle are in communication based on information received from the remote keyless entry system using the vehicle controller area network interface.

4. The tire pressure monitoring system electronic control unit of claim 1, wherein the control circuit is further configured to determine, based on information received using the vehicle controller area network interface, that at least one prior condition is satisfied, and wherein the control circuit sends the control signal only after determining that at least one prior condition is satisfied.

5. The tire pressure monitoring system electronic control unit of claim 4, wherein the prior condition is at least one of a key fob being in communication with a remote keyless entry system of the vehicle, the vehicle being in park, or an engine of the vehicle being off.

6. The tire pressure monitoring system electronic control unit of claim 5, wherein the information received using the vehicle controller area network interface is at least one of communication status information from a remote keyless entry system electronic control unit, transmission information from a transmission control unit, or engine state information from an engine control module.

7. The tire pressure monitoring system electronic control unit of claim 1, wherein the control circuit is further configured to determine, based on the pressure data, at least one of the number of times the tire has been kicked and a strength of a kick.

8. The tire pressure monitoring system electronic control unit of claim 7, wherein the number of times the tire is kicked is determined based on the number of times the control circuit determines the tire is kicked within a predetermined time period, and wherein the strength of the kick is determined using a series of increasing pressure threshold values.

9. The tire pressure monitoring system electronic control unit of claim 7, wherein the control circuit sends different control signals based on the number of times the tire has been kicked or the strength of the kick, and wherein the different control signals cause the vehicle to take different actions.

10. The tire pressure monitoring system electronic control unit of claim 1, wherein the hands free operation of the trunk is user customizable.

11. A method for operating a trunk of a vehicle based on a kick of a tire of the vehicle, comprising:

receiving pressure data at a control circuit from, directly or indirectly, one or more tire pressure monitoring system sensors;

determining, using the control circuit, if the tire of the vehicle has been kicked based on the pressure data; and

sending a control signal, directly or indirectly, to an actuator,

wherein the actuator opens the trunk of the vehicle in response to receiving the control signal.

12. The method of claim 11, further comprising determining, using the control circuit, if a prior condition is satisfied, where the control signal is not sent in response to determining that the prior condition is not satisfied.

13. The method of claim 12, wherein the prior condition is at least one of a key fob being in communication with a remote keyless entry system of the vehicle, the vehicle being in park, or an engine of the vehicle being off.

14. The method of claim 11, further comprising sending an instruction, directly or indirectly, to one or more tire pressure monitoring system sensors, wherein the instruction causes the tire pressure monitoring system sensor to exit a power saving mode and begin transmitting pressure data.

15. An apparatus for a vehicle and for hands free operation of a portion of the vehicle, comprising:

a tire pressure sensor configured to measure the pressure within a tire of the vehicle;

an actuator coupled to the portion of the vehicle and configured to cause the portion of the vehicle to open in response to a control signal; and

a control circuit configured to receive pressure data from the tire pressure sensor and configured to send the control signal to the actuator,

wherein the control circuit is configured to send the control signal in response to determining, based on the pressure data, that the tire has been kicked.

16. The apparatus of claim 15, wherein the control circuit is further configured to activate the tire pressure sensor in response to an initialization event.

17. The apparatus of claim 16, wherein the initialization event is at least one of establishing communications between a key fob and a remote keyless entry system, a camera system of the vehicle detecting a user, a camera system of the vehicle detecting a gesture of a user, a radar based system detecting a user, establishing communication between a Bluetooth communication system of the vehicle and a mobile phone, or the vehicle being within close geographic proximity to a specific location.

18. The apparatus of claim 15, wherein the control circuit is further configured to determine that at least one prior condition is satisfied prior to sending the control signal.

19. The apparatus of claim 15, wherein the control circuit is included in one of a tire pressure monitoring system electronic control unit, a body control module, a trunk electronic control unit, or a general purpose electronic control unit.

20. The apparatus of claim 15, wherein the control circuit is customizable by a user to control the operation of one or more of a trunk of the vehicle, a climate control system of the vehicle, an infotainment system of the vehicle, and a powertrain of the vehicle in response to determining that the tire has been kicked.
