Abstract

A wireless vehicle control device, disposed on a vehicle, includes a first communication unit, at least one second communication unit and a central management unit. The first communication unit is configured to detect a first communication signal of a portable electronic device. The at least one second communication unit is configured to detect a second communication signal of the portable electronic device, wherein a communication range of the at least one second communication unit is smaller than that of the first communication unit. The central management unit is configured to activate the at least one second communication unit to perform detection when determining that the first communication unit is paired with the portable electronic device according to the first communication signal, and control at least one vehicle lock according to the first communication signal when a distance corresponding to the second communication signal is not greater than a default distance.

First claim

What is claimed is:

1. A wireless vehicle control device, disposed on a vehicle, comprising:
a first communication unit configured to detect a first communication signal of a portable electronic device;
at least one second communication unit configured to detect a second communication signal of the portable electronic device, wherein a communication range of the at least one second communication unit is smaller than a communication range of the first communication unit;
a central management unit connected to the first communication unit and the at least one second communication unit, wherein the central management unit is configured to activate the at least one second communication unit to perform detection when determining the first communication unit is paired with the portable electronic device according to the first communication signal, and the central management unit is configured to control at least one vehicle lock according to the first communication signal when a distance corresponding to the second communication signal is not greater than a default distance;
a third communication unit connected to the central management unit, and configured to obtain a third communication signal of the portable electronic device; and
a charging unit connected to the central management unit,
wherein the central management unit is further configured to control the charging unit in coordination with the portable electronic device to perform a charging operation based on the third communication signal.

2. The wireless vehicle control device according to claim 1 , wherein before determining the first communication unit is paired with the portable electronic device according to the first communication signal, the central management unit is further configured to activate the first communication unit when triggered by a moving signal output by the portable electronic device.

3. The wireless vehicle control device according to claim 1 , wherein the central management unit further configured to control the charging unit in coordination with the portable electronic device to perform the charging operation based on the third communication signal is: the central management unit controlling the third communication unit to perform a foreign object detection on a receiving coil of the portable electronic device and controlling the charging unit to charge the portable electronic device after controlling the charging unit to detect the receiving coil.

4. The wireless vehicle control device according to claim 1 , wherein the at least one second communication unit is a plurality of second communication units, the at least one vehicle lock is a plurality of vehicle locks, the plurality of second communication units correspond to the plurality of vehicle locks respectively, the plurality of second communication units generate the respective second communication signal, the central management unit calculates a plurality of distances according to the second communication signals, and controls one of the plurality of vehicle locks corresponding to one of the plurality of second communication units with the distance not greater than the default distance.

5. The wireless vehicle control device according to claim 1 , wherein the central management unit is further configured to start the vehicle according to the third communication signal.

6. The wireless vehicle control device according to claim 1 , wherein the third communication unit is a near field communication unit.

7. The wireless vehicle control device according to claim 1 , wherein the first communication unit is a Bluetooth communication unit, and the at least one second communication unit is at least one ultra-wideband communication unit.

8. The wireless vehicle control device according to claim 1 , wherein the third communication signal comprises identification data, and controlling the at least one vehicle lock according to the first communication signal is performed when the central management unit determining that the identification data matches predetermined data.

9. The wireless vehicle control device according to claim 1 , wherein the first communication unit, the third communication unit and the charging unit are disposed on a same mainboard.
