The invention relates to the technical field of automobile electric control and intelligence, and discloses a steering-by-wire automobile road feeling simulation execution device and method, specifically, a road feeling simulation controller controls a magneto-rheological damper to generate a damping force with a certain magnitude according to a torque and the torque of an angle sensor, and road feeling can be generated according to the generated damping force; and the damping provided by the magneto-rheological shock absorber belongs to semi-active damping, so that the steering wheel cannot be dragged to rotate under the condition of control failure. Besides, the road feeling simulation controller controls an aligning torque compensation motor to act on the torsion elastic piece according to the torque of the torque and angle sensor under the condition that it is determined that the steering wheel needs to compensate the aligning torque, so that the torsion elastic piece generates the aligning torque of a certain magnitude. And the aligning torque is transmitted to the torque and angle sensor through the first shaft and is further transmitted to the steering wheel, so that the aligning function of the steering wheel is realized.
本申请涉及汽车电控以及智能技术领域,公开了一种线控转向汽车路感模拟执行装置及方法,具体地,路感模拟控制器根据转矩及转角传感器的转矩控制磁流变减振器产生一定大小的阻尼力,可根据产生的阻尼力产生路感;并且磁流变减振器提供的阻尼属于半主动阻尼,在控制失效的情况下也不会拖拽转向盘转动。除此之外,路感模拟控制器根据转矩及转角传感器的转矩,在确定转向盘需要补偿回正力矩的情况下,控制回正力矩补偿电机作用于扭转弹性件,使得扭转弹性件产生一定大小的回正力矩;进而将回正力矩通过第一轴传递到转矩及转角传感器,并进一步传递到转向盘实现转向盘的回正功能。
