Vehicle, control method and control device for power-assisted steering failure of vehicle and storage medium
The invention discloses a vehicle, a control method and device for power-assisted steering failure of the vehicle and a storage medium. The control method comprises the steps that the steering wheel turning angle, the vehicle speed and the actual hand torque value of the vehicle are obtained; determining a target hand torque value according to the steering wheel angle, the vehicle speed and the actual hand torque value; and when it is detected that the power-assisted steering of the vehicle fails, the current actual hand torque value is corrected according to the current actual hand torque value and the target hand torque value, so that the actual hand torque value follows the target hand torque value. According to the control method for the power-assisted steering failure of the vehicle, the hand torque value can be corrected through the current actual hand torque value and the target hand torque value under the condition that the power-assisted steering function is failed, so that the actual hand torque value follows the target hand torque value, and under the condition that the power-assisted steering function is failed, the power-assisted steering function is achieved while the differential power-assisted steering function is achieved. And a better steering hand feeling is provided for a driver.
本发明公开了一种车辆及其转向助力失效的控制方法、控制装置及存储介质，控制方法包括：获取车辆的方向盘转角、车速和实际手力矩值；根据方向盘转角、车速和实际手力矩值确定目标手力矩值；在检测到车辆转向助力失效时，根据当前实际手力矩值和目标手力矩值对当前实际手力矩值进行修正，以使实际手力矩值跟随目标手力矩值。本发明的车辆转向助力失效的控制方法，能够在转向助力功能失效的情况下，通过当前实际手力矩值和目标手力矩值对手力矩值进行修正，以使实际手力矩值跟随目标手力矩值，在转向助力功能失效情况下，实现差动助力转向功能的同时，为驾驶员提供驾驶员较好的转向手感。
