Abstract

The invention discloses a vehicle steering system control method and device and a vehicle. The method includes: detecting whether an ignition signal is acquire or not; controlling a vehicle steering system to start if the ignition signal is acquired; under the condition of starting of the vehicle steering system, if completion of power-off treatment of the vehicle is detected, controlling the vehicle steering system to stop operation in preset delay time. The problem of lack of steering power assistance when engine signals cannot be received under the condition that the vehicle travels on expressways or common roads is avoided, and steering wheel heaviness caused by engine failure, failure in receiving of engine signals or vehicle power off can be avoided, so that traveling safety of the vehicle is guaranteed, and safety of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method and device for a vehicle steering system and a vehicle. Background technique [0002] As the number of vehicles increases, users have higher and higher requirements for the safety and comfort of vehicles. At present, electric vehicles judge whether the electric steering system starts to work based on the ignition signal and the analog engine signal. Since the electric vehicle may not be able to receive the analog engine signal, this will lead to the problem of no power steering, which is not conducive to the safety of the vehicle. After the vehicle is parked, the position of the steering wheel is fixed according to the position when the vehicle is parked. In this way, when the vehicle is started again, it may deviate from the normal driving track, which is not conducive to the comfort of the vehicle. And if the steering wheel is not placed in the middle...
