Abstract

A vehicle electronic key system for unlocking a vehicle includes an electronic key and a vehicle controlling device. The electronic key includes a first controller, a signal transmitting module configured to collet and transmit speech signals, and a wireless charging receiving coil configured to transmit electromagnetic signals to the first controller. The vehicle controlling device includes a second controller configured to authenticate the speech signals and unlock the vehicle, a signal receiving module configured to receive speech signals sent by the signal transmitting module and send the speech signals to the second controller, and a wireless charging transmitting coil configured to transmit the electromagnetic signals to the wireless charging receiving coil. The second controller is further configured to drive the wireless charging transmitting coil. The first controller is configured to convert the electromagnetic signals to electric energy and send the electric energy to the signal transmitting module.

First claim

What is claimed is:

1 . A vehicle electronic key system for unlocking a vehicle, the vehicle electronic key system comprising:
an electronic key comprising
a first controller,
a signal transmitting module configured to collet and transmit speech signals, and
a wireless charging receiving coil configured to transmit electromagnetic signals to the first controller, and
a vehicle controlling device mounted on the vehicle comprising:
a second controller configured to authenticate the speech signals and unlock the vehicle,
a signal receiving module configured to receive speech signals sent by the signal transmitting module and send the speech signals to the second controller, and
a wireless charging transmitting coil configured to transmit the electromagnetic signals to the wireless charging receiving coil;
wherein the second controller is further configured to drive the wireless charging transmitting coil, and the first controller is configured to convert the electromagnetic signals to electric energy and send the electric energy to the signal transmitting module.

2 . The vehicle electronic key system of claim 1 ,
wherein the signal transmitting module comprises a speech acquisition module and a speech codec module electrically connected to the speech acquisition module; wherein the speech acquisition module is configured to collet the speech signals and convert the speech signals to analog signals; and wherein the speech codec module is configured to encode the analog signals to the digital signals.

3 . The vehicle electronic key system of claim 1 , wherein the signal receiving module is further configured to collet speech samples, and the signal receiving module comprises a vehicle speech acquisition module and a vehicle speech codec module.

4 . The vehicle electronic key system of claim 3 , wherein the second controller further comprises an authorization module configured to authenticate for user by comparing the speech signals collected by the signal transmitting module with the speech samples signals.

5 . The vehicle electronic key system of claim 4 , wherein the second controller further comprises a transmitting module, and the transmitting module is configured to receive the speech signals sent by the signal receiving module and send the speech signal to the authorization module.

6 . The vehicle electronic key system of claim 1 , wherein the vehicle controlling device further comprises a vehicle battery, and the vehicle battery is configured to send electric energy signal to the second controller.

7 . The vehicle electronic key system of claim 1 , wherein the vehicle controlling device further comprises a unlock module electrically connected to the second controller, and the unlock module is configured to lock and unlock the vehicle controlled by the second controller.

8 . The vehicle electronic key system of claim 1 , wherein the electronic key further comprises a battery electrically connected to the first controller, and the first controller is further configured to send the electric energy to the electronic key battery.
