The invention relates to a vehicle steering torque correction method and device, a vehicle and a storage medium, and the method comprises the steps: collecting the actual vehicle speed of the vehicle and the current torque of a steering wheel, and obtaining the steering torque of the steering wheel according to the actual vehicle speed and the current torque; judging whether the steering torque is greater than a preset threshold; if the steering torque is larger than the preset threshold value, a correction coefficient of the vehicle is matched according to the steering torque, and a current power-assisted steering curve of the vehicle is corrected according to the correction coefficient, so that the steering torque of the vehicle is output according to the corrected current power-assisted steering curve. Therefore, the problems that in the related technology, in the vehicle running process, the wheel steering angle continuously changes, consequently, the steering torque has large errors, the control accuracy of the wheel steering angle is low, the steering torque of the vehicle is difficult to correct accurately, the stability of steering performance is reduced, and the intelligence and practicability are low are solved.
本申请涉及一种车辆的转向力矩修正方法、装置、车辆及存储介质,其中,方法包括:采集车辆的实际车速和方向盘的当前力矩,并根据实际车速和当前力矩获取方向盘的转向力矩;判断转向力矩是否大于预设阈值;如果转向力矩大于预设阈值,则根据转向力矩匹配车辆的修正系数,并根据修正系数修正车辆的当前转向助力曲线,以按照修正后的当前转向助力曲线输出车辆的转向力矩。由此,解决了相关技术在车辆行驶过程中,车轮转向角度不断变化,导致转向力矩存在较大误差,且车轮转向角度的控制精准度较低,难以准确修正车辆的转向力矩,降低了转向性能的稳定性,智能性和实用性较低等问题。
