The invention provides a vehicle driving performance optimization method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the speed parameter of the vehicle and the opening degree of an accelerator pedal when determining that the vehicle is in an acceleration working condition; the basic torque slope of the driving motor is determined according to the speed parameters of the vehicle; the torque rising slope of the driving motor is determined according to the basic torque slope, the opening degree of the accelerator pedal and the speed parameters of the vehicle; and carrying out drivability filtering on the required torque of the driving motor according to the torque rising slope. According to the method, the torque rising slope of the driving motor is determined by introducing the speed parameters of the vehicle, the vehicle speed parameters such as the size of the vehicle are associated with the drivability filtering performance, the torque response requirements under different vehicle speeds and different accelerator pedal opening degrees are met, and therefore the drivability of the vehicle is improved.

    本发明提出一种车辆驾驶的性能优化方法及装置、车辆和存储介质,方法包括:确定车辆处于加速工况时,获取车辆的速度参数及加速踏板的开度;根据车辆的速度参数确定驱动电机的基础扭矩斜率;根据基础扭矩斜率、加速踏板的开度及车辆的速度参数确定驱动电机的扭矩上升斜率;根据扭矩上升斜率对驱动电机的需求扭矩进行驾驶性滤波。本发明通过引入车辆的速度参数确定驱动电机的扭矩上升斜率,将车辆速度参数例如车辆的大小与驾驶性滤波的性能进行关联,以实现不同车速及不同加速踏板开度下的扭矩响应需求,从而提高车辆的驾驶性能。
