System and method for control of motor vehicle - steer - by - wire - assemblies with an adjustable steering sensation

摘要

The present invention relates to a system and method for controlling a steering - by - wire - assembly (10) for generating an adjustable steering sensation for a vehicle driver by means of providing the control of the reaction moment on the steering wheel (44) of the vehicle. The method comprises a quantitative description of the steering sensation, the through establishment of a relationship of the steering wheel - reaction torque and steering wheel angle, wheel torque is obtained and the road speed. The system and method is followed by steering - by - wire - assemblies - circuit - return coupling controllers with internal moment loop, the steering wheel - speed - feedback loop and steering wheel - angle positions - feedback loop, in order to enable provision of the steering sensation, of the active steering wheel the rear of the barrel with different rotational speeds, of the steering wheel stops according to the wheel angle position during the parking and the generation of the directional - a reference angle to the wheels to implement.
