The invention discloses a torque dynamic compensation 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; in the accelerated driving state, first request torque and actual torque corresponding to all power sources of the vehicle are obtained, and the power sources comprise an engine, a front axle power generation motor, a front axle driving motor and a rear axle driving motor; and compensating the torque of at least one power source according to the first request torque and the actual torque so as to output a second request torque corresponding to each power source. According to the method, compensation is sequentially carried out from inside to outside from nearby parts or layers, the torque response precision and drivability of the vehicle can be improved in the vehicle acceleration process, and the driving experience is improved.
本发明公开了一种四驱车辆的扭矩动态补偿方法、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;在所述加速行驶状态下,获取所述车辆各个动力源对应的第一请求扭矩和实际扭矩,其中,所述动力源包括发动机、前桥发电电机、前桥驱动电机和后桥驱动电机;根据所述第一请求扭矩和所述实际扭矩,对至少一个所述动力源的扭矩进行补偿,以输出各个所述动力源对应的第二请求扭矩。该方法从就近的零部件或层级依次从内向外进行补偿,可以在车辆加速的过程中,提高车辆的扭矩响应精度和驾驶性,提升驾驶体验。
