Abstract
Method and apparatus are disclosed for mobile device tethering for a remote parking assist system of a vehicle. An example vehicle includes first and second wireless modules and a processor. The processor estimates a region of probability representative of possible locations of a mobile device based on a first signal strength indicator. When the region of probability overlaps a virtual boundary, the processor polls a key fob, estimates a distance of the key fob from the vehicle based on a second signal strength indicator, and when the key fob is within the virtual boundary, enable autonomous parking.
Claims20
A vehicle comprising:
- first and second wireless modules;
- and
- a processor configured to:
- estimate a region of probability representative of possible locations of a mobile device based on a first signal strength indicator;
- when the region of probability overlaps a virtual boundary:
- poll the mobile device;
- estimate a distance of the mobile device from the vehicle based on a second signal strength indicator;
- and
- when the mobile device is confirmed to be within the virtual boundary by the second signal strength indicator, enable autonomous parking.
A method to control a vehicle comprising:
- estimating, with a processor, a region of probability representative of possible locations of a mobile device based on a first signal strength indicator received from a first wireless module;
- when the region of probability overlaps a virtual boundary:
- polling the mobile device;
- estimating a distance of the mobile device from the vehicle based on a second signal strength indicator receives from a second wireless module;
- and
- when the mobile device is confirmed to be within the virtual boundary by the second signal strength indicator, enable autonomous parking.
A system comprising:
- a mobile device that communicates on a first set of frequencies;
- a remote parking application executing on the mobile device, the mobile device communicating on a second set of frequencies;
- a vehicle with first and second wireless modules and a processor, the vehicle configured to:
- estimate a region of probability representative of possible locations of the mobile device based on a first signal strength indicator;
- when the region of probability overlaps a virtual boundary:
- poll the mobile device;
- estimate a distance of the mobile device from the vehicle based on a second signal strength indicator;
- and
- when the mobile device is confirmed to be within the virtual boundary by the second signal strength indicator, perform remote parking commands received from the remote parking application.
