The invention relates to the technical field of locomotive driving, in particular to a locomotive torque control method, device and equipment and a storage medium. According to the method, filtering processing is conducted on an accelerator signal and a motor signal, and a filtered accelerator signal and a filtered motor signal are obtained; then according to the filtering accelerator signal and the filtering motor signal, the required torque is determined; and finally, determining a target driving torque according to the required torque and the tire slip coefficient. As the torque decision is made according to the filtered accelerator signal and the motor signal, when a locomotive passes through a bumpy road surface and feet of a driver bumpy up and down, the accelerator signal is filtered, a relatively stable numerical value is output, the road surface and the accelerator torque are prevented from vibrating, and the driving safety is improved. And meanwhile, the motor signal is also subjected to filtering processing, torque oscillation caused by shaking of a transmission chain or speed shaking is filtered out, and the comfort and the control performance of the vehicle are improved.
本发明涉及机车驱动技术领域,尤其涉及一种机车扭矩控制方法、装置、设备及存储介质,该方法通过分别对油门信号与电机信号进行滤波处理,得到滤波油门信号与滤波电机信号;然后根据滤波油门信号与滤波电机信号,确定需求扭矩;最后根据需求扭矩与轮胎打滑系数,确定目标驱动扭矩。由于本发明是根据滤波后的油门信号与电机信号来进行扭矩的决策,当机车经过颠簸路面,驾驶员的脚出现上下颠簸时,由于油门信号经过滤波处理,会输出一个较平稳的数值,防止路面和油门扭矩都在震荡,提升了车辆的舒适性和操控性能,同时,电机信号也经过滤波处理,过滤掉了传动链的抖动或者车速抖动引起扭矩震荡,提升了车辆的舒适性和操控性能。
