The invention discloses a vehicle motor torque determination method, device and system, a vehicle and a storage medium, relates to the technical field of vehicles, and aims to reduce the response time of an ESP to torque adjustment. The method comprises the steps that under the condition that a torque adjusting request sent by an electronic stability controller is received, vehicle driving parameters are obtained; determining a first prediction result and a second prediction result of the motor torque; the first prediction result is determined according to the vehicle battery output power, the vehicle DC conversion consumption power, the vehicle DC/AC consumption power, the vehicle thermal management consumption power, the vehicle speed, the vehicle tire radius, the vehicle torque transmission efficiency and the speed ratio of a vehicle main speed reducer; the second prediction result is determined according to the historical torque of the vehicle motor and the request torque of the vehicle motor; and weighting the first prediction result and the second prediction result to obtain a vehicle motor torque, and sending the vehicle motor torque to an electronic stability controller.

    本申请公开了一种车辆电机扭矩确定方法、装置、系统、车辆及存储介质,涉及车辆技术领域,以实现降低ESP对调整扭矩的响应时间。该方法包括:在接收到电子稳定控制器发送的扭矩调整请求的情况下,获取车辆行驶参数;确定电机扭矩的第一预测结果和第二预测结果;第一预测结果为根据车辆电池输出功率、车辆直流变换消耗功率、车辆直流交流消耗功率、车辆热管理消耗功率、车辆速度、车辆轮胎半径、车辆扭矩传递效率以及车辆主减速器的速比确定的,第二预测结果为根据车辆电机历史扭矩以及车辆电机请求扭矩确定的;将第一预测结果和第二预测结果进行加权处理,得到车辆电机扭矩,并向电子稳定控制器发送车辆电机扭矩。
