The invention discloses an intelligent networked passenger car torque gradient self-adaptive adjustment control method and system, and relates to the technical field of intelligent networked vehicles, and the method comprises the steps: obtaining state data in a vehicle driving process in real time; according to the acquired data, determining a motor driving torque required at the current moment, and further determining a motor expected torque at the current moment; the driving state of the vehicle at the current moment is determined, and the lifting torque state and the expected torque gradient at the current moment are determined in combination with the expected torque of the motor; based on the expected torque gradient at the current moment and the actual torque gradient at the previous moment, torque gradient self-adaptive adjustment based on set scale progressive increase or progressive decrease is carried out, and the actual torque gradient at the current moment is obtained; and adding and subtracting the actual torque of the motor based on the actual torque gradient at the current moment, calculating to obtain a final target request torque, and sending the final target request torque to a motor controller for torque smooth control. Smooth control over the torque can be achieved, the driving comfort is improved, and the service life of the vehicle is prolonged.

    本发明公开一种智能网联客车扭矩梯度自适应调整控制方法及系统,涉及智能网联车辆技术领域,包括:实时获取车辆驾驶过程中的状态数据;根据获取的数据,确定当前时刻所需的电机驱动扭矩,进而确定当前时刻的电机期望扭矩;确定车辆当前时刻的驾驶状态,再结合电机期望扭矩,确定当前时刻的升降扭矩状态及期望扭矩梯度;基于当前时刻的期望扭矩梯度和上一时刻的实际扭矩梯度,进行基于设定尺度递增或递减的扭矩梯度自适应调节,得到当前时刻的真实扭矩梯度;基于当前时刻的真实扭矩梯度与电机实际扭矩相加减,计算得到最终的目标请求扭矩,并发送至电机控制器进行扭矩平滑控制。本发明可实现扭矩的平滑控制,提高驾驶舒适性及车辆使用寿命。
