The invention relates to a pedal torque compensation control method and system under a climbing working condition and a vehicle. The method comprises the following steps that S1, whether the vehicle speed is larger than a or not is judged; s2, whether the opening degree of the accelerator pedal is larger than b or not is judged; s3, judging whether the gradient value signal c of the gradient sensor is greater than c0 or not; s4, judging whether the time of the gradient value signal of the gradient sensor is greater than t; s5, according to the current slope value c, the pedal torque is made into an initial compensation torque value F1 of 10%-30%; and S6, the vehicle acceleration 0 serves as a target value, the initial compensation torque F1 is calculated through a PID algorithm, and compensation torque F2 is determined and output. By the adoption of the method, when the vehicle drives into the road surface with the large upslope gradient from the stable road or drives to the stable road surface from the road surface with the large upslope gradient, the driving acceleration of the vehicle does not change along with changes of the road conditions, and the driving experience comfort is improved.
本发明涉及一种爬坡工况下的踏板扭矩补偿控制方法、系统及车辆,方法包括以下步骤:S1、判断车速是否大于a;S2、判断油门踏板开度是否大于b;S3、判断坡度传感器坡度值信号c是否大于c0;S4、判断坡度传感器坡度值信号的时间是否大于t;S5、根据当前坡度值c,将踏板扭距做一个10%‑30%的初始补偿扭距值F1;S6、以车辆加速度0为目标值,对初始补偿扭矩F1使用PID算法计算,确定补偿扭矩F2进行输出。采用本发明车辆在从平稳道路驶入较大上坡坡度路面或者从较大上坡坡度路面行驶到平稳路面,车辆的行驶加速度不会随着路况的改变而变化,增加了驾驶体验舒适性。
