Dual purpose wireless device, wherein vehicle controls depend on device location
View Patent ↗A communications system utilizing a portable communications device for controlling functions in a vehicle includes a first display for controlling vehicle operating functions and a first transceiver connected to the first display device. A multifunctional control switch is connected to the first display device, while a second transceiver is used for communicating with either the first transceiver or a remote keyless entry (RKE) receiver depending upon whether the second transceiver is located inside or outside the vehicle. The second transceiver operates to configure operational parameters of the display device when those controls have not been readily integrated into the vehicle center stack.
1. A communications system utilizing a dual mode device for controlling functions in a vehicle, said system comprising:
a first wireless transceiver configured to be installed in the vehicle;
a dual mode device equipped with a second wireless transceiver configured to communicate with the first wireless transceiver, said dual mode device configured to be portable with respect to the vehicle; and
a controller configured to be installed in the vehicle and coupled to the first wireless transceiver, said controller configured to control a first predetermined set of vehicle functions only in the case in which the controller determines that the dual mode device is located outside the vehicle, and configured to control a second predetermined set of vehicle functions distinct from the first predetermined set of vehicle functions only in the case in which the controller determines that the dual mode device is located inside the vehicle, wherein the controller is configured to determine that the dual mode device is located outside the vehicle only in the case in which the first wireless transceiver is communicating with the second wireless transceiver and the vehicle is not moving, and wherein the controller is configured to determine that the dual mode device is located inside the vehicle only in the case in which the first wireless transceiver is communicating with the second wireless transceiver and the vehicle is moving.
2. The system of claim 1 , said system further including a human machine interface (HMI) for controlling vehicle functions, said human machine interface in communication with the controller.
3. The system of claim 1 , said system further including a first display for controlling the second predetermined set of vehicle functions, said first display in communication with the controller.
4. The system of claim 3 , wherein the first display is reconfigurable using the dual mode device.
5. The system of claim 1 , wherein the dual mode device includes a keyboard control configured to control the dual mode device.
6. The system of claim 1 , wherein the dual mode device includes a second display.
7. The system of claim 1 , wherein the dual mode device is configured as a key fob.
8. The system of claim 1 , wherein the first predetermined set of vehicle functions is at least one selected from the group consisting of remote start, door lock, door unlock, exterior lighting, horn, window control, seat control, interior lighting, heater, ventilation and air conditioning (HVAC) system control, and window defrost.
9. The system of claim 1 , wherein the second predetermined set of vehicle functions is at least one selected from the group consisting of window control, seat control, interior lighting, heater, ventilation and air conditioning (HVAC) system control, window defrost, audio system control, and navigation system control.
