A device binding, unbinding method, car locking method and related equipment

Abstract

The invention provides a device binding and unbinding method, a car locking method and related devices. The device binding method is applied to a vehicle positioning device, and the vehicle positioning device is electrically connected to an electronic control unit. The method includes: the vehicle positioning device receives electronic control The first message sent by the unit; the vehicle positioning device generates and generates the first verification information according to the first random number; the vehicle positioning device sends the first random number to the electronic control unit so that the electronic control unit generates the second verification information according to the first random number The vehicle positioning device receives the second verification information and the first device identification of the electronic control unit; the vehicle positioning device judges that the two verification information are the same, then the vehicle positioning device stores the first device identification and sends verification information to the electronic control unit to use The electronic control unit starts the lock function. The invention can realize automatic binding between devices, is simple to operate, randomly generates verification information through a predetermined algorithm, is difficult to be cracked, and improves security.

Description

technical field [0001] The invention relates to the field of motor vehicle locking, in particular to a device binding and unbinding method, a vehicle locking method and related equipment. Background technique [0002] Before the motor vehicle leaves the factory, the manufacturer will bind the vehicle positioning device and the electronic control unit. After the binding is successful, there will be a one-to-one correspondence between the vehicle positioning device and the electronic control unit, and the electronic control unit will enable the lock function. [0003] The existing binding technology between the vehicle positioning device and the electronic control unit is bound by sending various messages manually. The manufacturer sends a binding message to the vehicle positioning device through the Internet of Things or a mobile phone. If the binding password in the binding message is the same as the binding password stored in the electronic control unit, the binding is succ...

AI Technical Summary

Problems solved by technology

[0004] In the existing binding technology between the vehicle positioning equipment and the electronic control unit, the content of the message sent by the manufacturer is similar, and the set binding and unbinding passwords are the same, which is very easy to be monitored and cracked. Once cracked, illegal Molecules can untie the message to the vehicle positioning device to make the electronic control unit turn off the car lock function, and the user can avoid being identified and locked, thereby avoiding repayment and causing economic losses to the manufacturer
