Abstract

Method and apparatus are disclosed for mobile device tethering for a remote parking assist system of a vehicle. An example vehicle includes a plurality of proximity sensors and a body control module. In response to detecting a mobile device proximate one of the proximity sensors, the body control module sends a location associated with the corresponding proximity sensor to the mobile device. The body control module receives, from the mobile device, a relative position of the mobile device from the location, and when the mobile device is within a threshold distance of the vehicle, enables autonomous parking.

Claims

1. A vehicle comprising:

a proximity sensor; and

a processor; and

a memory storing computer-executable instructions, that when executed by the processor, cause the processor to;

provide an instruction to a mobile device to bring the mobile device within a provided range of the proximity sensor;

determine that the mobile device is within the provided range of the proximity sensor;

determine, based on the determination that the mobile device is within the provided range of the proximity sensor, an initial location of the mobile device relative to the vehicle;

periodically determine the location of the mobile device relative to the vehicle, based on the initial location of the mobile device and dead reckoning on the mobile device;

determine, based on the location of the mobile device relative to the vehicle, that the mobile device is within a threshold distance of the vehicle; and

enable, based on the determination that the mobile device is within a threshold distance of the vehicle, an autonomous parking operation.

2. The vehicle of claim 1, wherein the proximity sensor comrpises a plurality of proximity sensors that are mounted on an external surface of the vehicle.

3. The vehicle of claim 2, wherein a first one of the plurality of proximity sensors is mounted on a rear of the vehicle, and wherein a second one of the plurality of proximity sensors is mounted on a front of the vehicle.

4. The vehicle of claim 2, wherein the plurality of proximity sensors are mounted on a housing of each of side view mirrors.

5. The vehicle of claim 2, wherein one of the plurality of proximity sensors is incorporated into a keyless entry keypad.

6. The vehicle of claim 1, wherein the proximity sensor comprises a plurality of proximity sensors that are physical switches that detect a force caused by the mobile device being pressed against the corresponding one of the plurality of proximity sensors.

7. The vehicle of claim 1, wherein the proximity sensor comprises a plurality of proximity sensors that are wireless nodes that detects electromagnetic signals produced by the mobile device.

8. The vehicle of claim 7, wherein the plurality of proximity sensors are near field communication devices.

9. The vehicle of claim 7, wherein the plurality of proximity sensors are personal wireless network devices that determine the mobile device is proximate one of the plurality of proximity sensors when a signal strength of the electromagnetic signals produced by the mobile device is greater than a threshold signal strength.

10. The vehicle of claim 9, wherein the threshold signal strength is set so that one of the plurality of proximity sensors detects the mobile device when the mobile device is less than 10 millimeters away.

11. A method to control a vehicle comprising:

providing an instruction to a mobile device to bring the mobile device within a provided range of a proximity sensor on the vehicle;

determining that the mobile device is within the provided range of the proximity sensor;

determining, based on the determination that the mobile device is within the provided range of the proximity sensor, an initial location of the mobile device relative to the vehicle;

periodically determining the location of the mobile device relative to the vehicle, based on the initial location of the mobile device and dead reckoning on the mobile device;

determining, based on the location of the mobile device relative to the vehicle, that the mobile device is within a threshold distance of the vehicle; and

enabling, based on the determination that the mobile device is within a threshold distance of the vehicle, an autonomous parking operation.

12. The method of claim 11, wherein the proximity sensor comprises a plurality of proximity sensors mounted on an external surface of the vehicle.

13. The method of claim 12, wherein a first one of the proximity sensors is mounted on a rear of the vehicle, and a second one of the proximity sensors is mounted on a front of the vehicle.

14. The method of claim 12, wherein the plurality of proximity sensors are mounted on a housing of each of side view mirrors.

15. The method of claim 12, wherein one of the plurality of proximity sensors is incorporated into a keyless entry keypad.

16. The method of claim 11, wherein the proximity sensor comprises a plurality of proximity sensors that are physical switches that detect a force caused by the mobile device being pressed against the corresponding one of the plurality of proximity sensors.

17. The method of claim 11, wherein the proximity sensor comprises a plurality of proximity sensors that are wireless nodes that detects electromagnetic signals produced by the mobile device.

18. The method of claim 17, wherein the plurality of proximity sensors are near field communication devices.

19. The method of claim 17, wherein the plurality of proximity sensors are personal wireless network devices that determine the mobile device is proximate one of the plurality of proximity sensors when a signal strength of the electromagnetic signals produced by the mobile device is greater than a threshold signal strength.

20. The method of claim 19, wherein the threshold signal strength is set so that one of the plurality of proximity sensors detects the mobile device when the mobile device is less than 10 millimeters away.
