Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 Shown is a working flow chart of a method for locking an electronic steering column lock of an electric vehicle according to the present invention. The electric vehicle has no parking gear and the motor and wheels of the electric vehicle are connected by a hard connection. The method includes:

[0050] Step S101, obtaining motor speed information;

[0051] Step S102, when the motor speed information satisfies the preset locking condition, send a locking request to the electronic steering column lock control unit, the locking request is used for the electronic steering column lock control unit to receive the locking When requested, lock the electronic steering column.

[0052] The wheel speed is a condition for judging whether the vehicle is stationary, and the antilock brake system (ABS) can provide the wheel...

Abstract

The invention discloses a method and system for locking an electronic steering column lock of an electric vehicle. The method includes: obtaining motor speed information; when the motor speed information satisfies a preset locking condition, sending a lock to the electronic steering column lock control unit The locking request is used for locking the electronic steering column when the electronic steering column lock control unit receives the locking request. The present invention judges whether the vehicle is stationary through the motor speed. The invention is aimed at electric vehicles without a gearbox, but driven by a motor and having a fixed reduction ratio between the motor speed and the wheel speed, so that the electric vehicle can apply an electronic steering column lock.

Description

technical field [0001] The invention relates to the technical field related to electric vehicles, in particular to a method and system for locking an electronic steering column lock of an electric vehicle. Background technique [0002] Electronic steering column lock (ESCL) is a vehicle anti-theft technology that locks and unlocks the steering column through a locking system to protect the safety of the vehicle. Since the electronic steering column lock will lock the steering column, if the vehicle is accidentally locked during driving, the vehicle will not be able to turn during driving, which is extremely dangerous. Therefore, when the electronic steering column lock technology is locked, it is necessary to ensure that the vehicle is in an absolute static state. [0003] The judging mechanism of the electronic steering column lock in the prior art is aimed at traditional cars. At present, most of the traditional car models will be set with a P gear. In combination, the t...
