Wireless identity authentication type electric vehicle burglar alarm

Abstract

The invention discloses a burglar alarm which does not need manual operation, performs driver identity authentication every time when an electric vehicle brakes, and controls the operating state of an electric vehicle motor. The burglar alarm comprises an electric vehicle-mounted control device and a driver identity authentication device carried by a driver, the electric vehicle-mounted control device and the driver identity authentication device are used in a separated mode and can perform two-way wireless communication within the range of more than one meter, and communication content is encrypted and changes in real time. When the electric vehicle-mounted control device detects that the vehicle starts to brake from a stationary state, identity authentication requests are sent around in a wireless mode, and the driver identity authentication device receives request signals and performs decryption, gives wireless response signals when the request signals are confirmed to be legal, and otherwise does not act. When receiving the effective response signals, the electric vehicle-mounted control device drives a motor in an enabling mode, the vehicle runs normally, and otherwise motor driving is forbidden, the vehicle cannot run. The burglar alarm has the advantages that during each braking, the burglar alarm performs automatic driver identity authentication, and therefore burglary prevention is performed in real time; two-way encryption is performed on wireless communication, and therefore the burglar alarm is safe and reliable.

Description

technical field [0001] The invention relates to an anti-theft device for an electric vehicle, in particular to an anti-theft device for identifying the legal identity of a driver and controlling whether the motor of the electric vehicle is working or not every time the brake is applied. Background technique [0002] Electric vehicles have become an indispensable part of people's lives. There are nearly 200 million in our country. However, the theft of electric vehicles is also very serious. More and more electric vehicles are equipped with electronic anti-theft devices. [0003] Most of the electric vehicle anti-theft devices currently in use are of early warning type: [0004] One is the anti-theft alarm, such as patent 02262927.0, which includes an electronic key and a vehicle-mounted vibration sensor. After the authorized person sets the protection state for the anti-theft alarm through the radio signal sent by the electronic key, when an unauthorized person performs an i...

Problems solved by technology

[0008] One is the GPS anti-theft device, which binds the vehicle with the GPS positioning device and allows the owner to communicate with the GPS positioning device through the mobile phone. This type of anti-theft device can effectively provide the location after the electric vehicle is stolen, but the price is high, the operation is more complicated, and it cannot be prevented. Thieves operate and destroy the driving car, the anti-theft effect is limited, and real-time anti-theft cannot be achieved

[0009] One is the anti-theft monitoring system for electric vehicles (application number 201110068499.6). The method is to deploy radio frequency card reading devices around the road, and to identify whether the two paired radio frequency cards carried by the electric vehicle and the driver are effectively matched. Deploy and install a large number of card reading devices in public places such as roads and communities, which is difficult and costly to implement
