The invention relates to a torsional vibration torque control method and device, electronic equipment, a storage medium and a vehicle, and the method comprises the steps: obtaining a response torque at a target moment, a torsional vibration torque at a previous moment and a target output period of a motor torque in response to a first torsional vibration enabling request sent by a power domain controller, and outputting a slope limit threshold value according to a preset motor torque, and determining the maximum output slope of the torsional vibration torque according to the torsional vibration torque at the last moment, the response torque at the target moment and the target output period, and determining the output range of the output first torsional vibration torque according to the torsional vibration torque at the last moment, the maximum output slope of the torsional vibration torque and the target output period. The output slope of the torsional vibration torque is limited, so that the output range of the output first torsional vibration torque is controlled, the situation that the torque of the motor is suddenly changed and the torsional vibration torque is stepped due to the torsional vibration torque is avoided, the torsional vibration out-of-control risk of the hybrid electric vehicle is effectively reduced, the stability of a power system is improved, and the service life of the hybrid electric vehicle is prolonged. And user experience is improved.
本发明涉及一种扭振扭矩控制方法、装置、电子设备、存储介质及车辆,包括:响应于动力域控制器发送的第一扭振使能请求,获取目标时刻的响应扭矩,上一时刻的扭振扭矩和电机扭矩的目标输出周期,根据预设的电机扭矩输出斜率限制阈值,目标时刻的响应扭矩和目标输出周期,确定扭振扭矩最大输出斜率,根据上一时刻的扭振扭矩,扭振扭矩最大输出斜率和目标输出周期,确定输出的第一扭振扭矩输出范围。本发明通过对扭振扭矩的输出斜率进行限制,从而控制输出的第一扭振扭矩的输出范围,进而避免因为扭振扭矩导致电机的扭矩产生突变,出现扭振扭矩阶跃的情况,有效地降低了混动汽车扭振失控风险,提高了动力系统稳定性,提升用户体验。
