The invention discloses a steering-by-wire system considering driver force decline and a road feeling control method thereof, and the method comprises the steps: collecting a steering wheel torque signal, a vehicle speed signal, a steering execution motor corner torque signal and a driver surface electromyogram signal of a vehicle, and processing the obtained driver surface electromyogram signal; the muscle activation degree of the driver and the steering discomfort of the driver are calculated; calculating ideal road sensing torque considering driver force decline; the current corresponding to the ideal road sensing torque is calculated, and the road sensing motor output torque is controlled in real time to track the ideal road sensing torque, so that the actual steering discomfort of the driver can track the ideal steering discomfort. The method provided by the invention can meet the individual demand of the driver on the road feeling force, and provides better driving experience and safety guarantee for the driver.
本发明公开了一种考虑驾驶员力衰退的线控转向系统及其路感控制方法,包括:采集车辆的方向盘转矩信号、车速信号、转向执行电机转角转矩信号和驾驶员表面肌电信号,并对得到的驾驶员表面肌电信号进行处理,计算驾驶员肌肉激活度及驾驶员的转向不舒适度;计算考虑驾驶员力衰退的理想路感力矩;计算得理想路感力矩相应的电流,实时控制路感电机输出转矩跟踪理想路感力矩,以实现驾驶员实际转向不舒适度跟踪理想转向不舒适度。本发明的方法能够满足驾驶员对路感力的个性化需求,为驾驶员提供更好的驾驶体验和安全保障。
