Equipment binding and unbinding method, vehicle locking method and related equipment

Abstract

The invention provides an equipment binding and unbinding method, a vehicle locking method and related equipment. The equipment binding method is applied to vehicle positioning equipment, and the vehicle positioning equipment is electrically connected with an electronic control unit. The equipment binding method comprises the following steps of enabling the vehicle positioning equipment to receivea first message sent by the electronic control unit; enabling the vehicle positioning equipment to generate first verification information according to a first random number; enabling the vehicle positioning equipment to send the first random number to the electronic control unit, and enabling the electronic control unit to generate second verification information according to the first random number; enabling the vehicle positioning equipment to receive the second verification information and a first equipment marker of the electronic control unit; enabling the vehicle positioning equipmentto store the first equipment marker, and send the verification passing information to the electronic control unit when the vehicle positioning equipment judges that the first verification informationand the second verification information are the same, so as to enable the electronic control unit to start the locking function. The equipment binding method has the advantages that the automatic binding between the equipment is realized, the operation is simple, the identification information is randomly generated according to an established algorithm, the easiness in decrypting is avoided, and the security is improved.

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
