The invention discloses a torque filtering method and device for a four-wheel-drive vehicle, the vehicle and a storage medium. The method comprises the steps that it is determined that the vehicle is in an accelerated driving state; obtaining driving information of the vehicle; determining a wheel end total torque rising slope and a front and rear axle torque rising slope distribution ratio according to the driving information; according to the wheel end total torque rising slope and the front and rear axle torque rising slope distribution ratio, the request torque of the front and rear axles is filtered, the filtered request torque of the front and rear axles is output, and the wheel end total torque rising slope is made to be a constant value. And the sum of the rear axle request torque rising slope and the front axle request torque rising slope is equal to the wheel end total torque rising slope, so that when a driver accelerates under different front and rear axle torque distribution ratios, the same whole vehicle acceleration feeling is achieved, and the driving experience is improved.
本发明公开了一种四驱车辆的扭矩滤波方法、装置、车辆及存储介质,所述方法包括:确定车辆处于加速行驶状态;获取所述车辆的行驶信息;根据所述行驶信息,确定轮端总扭矩上升斜率和前后桥扭矩上升斜率分配比;根据所述轮端总扭矩上升斜率和前后桥扭矩上升斜率分配比对前后桥的请求扭矩进行滤波,以输出前后桥滤波后的请求扭矩,使得轮端总扭矩上升斜率为恒定值,且后桥请求扭矩上升斜率和前桥请求扭矩上升斜率之和等于轮端总扭矩上升斜率,从而驾驶员在不同前后桥扭矩分配比下进行加速时,有同样的整车加速感,提升驾驶体验。
