Vehicle intelligent lock, intelligent key and starting method

Abstract

The invention discloses a vehicle intelligent lock, an intelligent key and a starting method. The vehicle intelligent lock comprises a vehicle-mounted part and an intelligent key, wherein the vehicle-mounted part also comprises a coil powered by a power supply; and the intelligent key also comprises a low-frequency induction module, and the low-frequency induction module can produce induced current when being positioned in the induction range of the coil, so that the current can be supplied to a controller and a radio-frequency module to transmit radio-frequency signals. By adding the coil powered by a power supply into the vehicle-mounted part of the vehicle intelligent lock and adding the low-frequency induction module which can supply the produced induction current to the controller and the radio-frequency module when being positioned in the induction range of the coil to the intelligent key part of the vehicle intelligent lock, the invention realizes that the intelligent key part can realize the power supply to the radio-frequency module by means of induction current so as to transmit radio-frequency signals and verify the vehicle-mounted part without using the power supplied by the original power supply.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, and more specifically, relates to an automobile intelligent lock, an intelligent key and a starting method thereof. Background technique [0002] In the automotive field, cars usually use traditional mechanical keys to start the engine of the car. With the development of technology, the keyless start system is gradually becoming popular. The keyless start system means that after the driver enters the vehicle, the engine can be started without using a traditional mechanical key. The driver can start the engine through a button installed on the instrument panel or a button on the remote control. [0003] The Chinese patent application with the application number CN200820123754.6 discloses a car starting system having both a mechanical key starting function and a keyless starting function. It mainly includes: ignition switch, start knob, mechanical key socket, locking mechanism, mec...

AI Technical Summary

Problems solved by technology

[0004] However, the smart key of the above-mentioned car start system needs a built-in battery to supply power for the relevant RF transmitter module of the smart key. When the battery in the smart key is insufficient, the smart key will not be able to send a car product signal, and it will not be possible to start the car through the keyless way. start the car

Therefore, the above-mentioned car starting system cannot be applied to a starting system that does not have a mechanical key starting function but only has a keyless starting function. The switch and start button are reserved for the design of the mechanical key jack, which increases the system cost
