Vehicle key system and use method thereof

Abstract

A vehicle key system includes a transmitting device and a receiving device; the transmitting device includes a signal transmitting module, a light source module, a wireless recharge receiver and a wireless signal conversion controller; the receiving device includes an optical signal conversion assembly, a signal receiving module, an electric energy conversion controller and a wireless recharge transmitter; the signal transmitting module generates a dimming signal and controls the light source module to generate an optical signal with preset identity authentication information; the optical signal conversion module is used for converting the optical signal into an electrical signal; the signal receiving module is used for performing identity authentication on the electrical signal and controlling unlocking of a vehicle; the electric energy conversion controller is used for converting electric energy into an electromagnetic signal and driving the wireless recharge transmitter to transmit the electromagnetic signal to the wireless recharge receiver; and the wireless recharge receiver senses and receives the electromagnetic signal, couples the electromagnetic signal, generates electrical energy, and transmits the electrical energy to the signal transmitting module and the light source module. The invention provides a use method of the vehicle key system.

Description

technical field [0001] The invention relates to the field of vehicle intelligence, in particular to an intelligent vehicle key system and a using method thereof. Background technique [0002] At present, the keys of vehicle door locks include mechanical keys and intelligent remote control keys. The mechanical key realizes pairing with the vehicle and anti-theft through the combination of different tooth shapes. The smart remote control key sends electromagnetic waves to the vehicle to unlock the vehicle by pressing the physical button. [0003] However, the number of mechanical key combinations is limited, which may result in the same key tooth combination, thus losing the anti-theft effect; at the same time, once the mechanical key is obtained by others, the other person can easily unlock the vehicle and drive the vehicle away. The smart remote control key unlocks the vehicle by emitting radio waves. Since the radio waves are scattered and propagated, it is easy to cause ...

[0003] However, the number of mechanical key combinations is limited, which may result in the same key tooth combination, thus losing the anti-theft effect; at the same time, once the mechanical key is obtained by others, others can easily unlock the vehicle and drive the vehicle away

The smart remote control key unlocks the vehicle by emitting radio waves. Since the radio waves are scattered and propagated, it is easy to cause the leakage of unlocking information and poor anti-theft performance. At the same time, with the development of wireless technology, there may be a variety of radio waves around the vehicle to be unlocked. , which interferes with the radio waves emitted by the smart remote control key, resulting in failure to unlock the vehicle
