Problems solved by technology
[0002] In related technologies, for example, in passenger cars and other models, in order to improve the operability of vehicle steering, a steering system is usually provided. When the vehicle is turning, the steering motor is operated at a certain speed to achieve steering assist for the wheels. Bring a good feel when the driver turns the steering wheel. However, the steering motor of the steering system in the related art usually runs at a certain speed during the operation of the vehicle, thus increasing the energy consumption of the vehicle. Moreover, the speed of the steering motor The higher the energy consumption

The invention discloses a control method of a vehicle steering system and the vehicle thereof, wherein the steering system includes a steering motor, and the control method of the vehicle steering system includes the following steps: obtaining the current driving speed of the vehicle and the current steering angular velocity of the steering wheel; The current steering angular velocity determines whether the steering wheel enters the preset state; when it is determined to enter the preset state, timing is performed to obtain the timing time of the preset state; if the timing time is greater than or equal to the time threshold, it is calculated based on the current driving speed and timing time Get the target speed, and adjust the actual speed of the steering motor according to the target speed. The control method of the vehicle steering system according to the embodiment of the present invention can adjust the actual rotational speed of the steering motor in time without affecting the steering comfort of the driver, so as to reduce energy consumption. The control accuracy and reliability of the steering motor speed.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method of a vehicle steering system and a vehicle thereof. Background technique [0002] In related technologies, for example, in passenger cars and other models, in order to improve the maneuverability of vehicle steering, a steering system is usually provided. When the vehicle is turning, the steering motor is operated at a certain speed, thereby realizing steering assistance to the wheels. Bring a good feel when the driver turns the steering wheel. However, the steering motor of the steering system in the related art usually runs at a certain speed during the operation of the vehicle, thus increasing the energy consumption of the vehicle. Moreover, the speed of the steering motor The higher the energy consumption is. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. The...
