The invention provides a vehicle torque determining method and device, and relates to the technical field of vehicles, the method comprises the steps that under the condition that a vehicle is in a sliding energy recovery state, current state information of the vehicle is obtained, and the current state information of the vehicle comprises current gear information of the vehicle; under the condition that the current gear information of the vehicle is the first gear, target torque is determined based on the basic torque relation table; under the condition that the current gear information of the vehicle is a second gear, target torque is determined based on the basic torque relation table and/or the current opening degree of an accelerator pedal; and the output torque of a motor in the vehicle is controlled to be transited to the target torque. Therefore, the more accurate and reliable target torque can be determined on the basis of the current gear information of the vehicle in combination with the basic torque relation table, the current opening degree of the accelerator pedal and the like, and the motor is controlled on the basis of the target torque, so that torque transition of the motor is more reliable.

    本申请提供一种车辆扭矩的确定方法及装置,涉及车辆技术领域,该方法包括:在车辆处于滑行能量回收状态的情况下,获取车辆当前的状态信息,车辆当前的状态信息包括所述车辆当前的挡位信息;在车辆当前的挡位信息为第一挡位的情况下,基于基础扭矩关系表,确定目标扭矩;在车辆当前的挡位信息为第二挡位的情况下,基于基础扭矩关系表和/或加速踏板当前的开度,确定目标扭矩;控制车辆中电机的输出扭矩向所述目标扭矩进行过渡。由此,可以基于车辆当前的挡位信息,结合基础扭矩关系表及加速踏板当前的开度等,确定出更为准确可靠的目标扭矩,并基于该目标扭矩对电机进行控制,从而使得电机的扭矩过渡更为可靠。
