The invention relates to the field of new energy vehicles, and provides a vehicle torque regulation and control method and device, a new energy vehicle and a storage medium. The method comprises the steps of screening out a target order in an online car-hailing mode; if it is monitored that the vehicle is in the energy recovery working condition, controlling the vehicle to enter a first regulation and control mode, determining a recovery torque attenuation factor and sending the recovery torque attenuation factor to a motor controller, so that the motor controller gradually reduces a whole vehicle sliding recovery torque value of a driving motor through a transmission system according to the recovery torque attenuation factor; and if the vehicle is in the driving working condition, the vehicle is controlled to enter a second regulation and control mode, and the driving torque attenuation gradient is determined and sent to the motor controller, so that the motor controller conducts gradient attenuation on the whole vehicle demand torque of the driving motor through the transmission system according to the driving torque attenuation gradient. According to the invention, more intelligent vehicle torque regulation and control can be realized, the operation convenience of the online car-hailing vehicle is better improved, and the travel safety and comfort of the online car-hailing vehicle are improved at the same time.

    本申请涉及新能源汽车领域,提供了一种车辆扭矩调控方法、装置、新能源汽车及存储介质。该方法包括:在网约车模式下,筛选出目标订单;若监测到车辆处于能量回收工况,则控制车辆进入第一调控模式,确定回收扭矩衰减因子并发送给电机控制器,以使电机控制器按照回收扭矩衰减因子通过传动系统逐渐减小驱动电机的整车滑行回收扭矩值;若车辆处于驱动工况,则控制车辆进入第二调控模式,确定驱动扭矩衰减梯度并发送给电机控制器,以使电机控制器按照驱动扭矩衰减梯度通过传动系统对驱动电机的整车需求扭矩进行梯度衰减。本申请可实现更加智能化的车辆扭矩调控,更好地提升网约车运行的便利性,同时提升网约车出行的安全性和舒适性。
