The invention discloses a torque determination method and device and a vehicle, and belongs to the technical field of vehicles. Comprising the steps of obtaining battery pack discharge power of a target vehicle in response to a starting instruction for a target mode of the target vehicle; based on the battery pack discharging power and the power limiting coefficient, the driving power of the target vehicle is limited, and target available power is obtained; and based on the target available power, the current motor rotating speed of the driving motor and the target output torque, the motor driving torque is determined, the target output torque is the torque capable of being output by the driving motor of the target vehicle at the current motor rotating speed, and the motor driving torque is the maximum output torque of the limited driving motor for driving the target vehicle to run. The vehicle speed in the vehicle driving process is limited by limiting the driving power, so that the probability of vehicle accidents is reduced, the phenomenon of vehicle damage is reduced, and the property loss of a vehicle owner is avoided as much as possible.

    本申请公开了一种扭矩确定方法、装置和车辆,属于车辆技术领域。包括:响应于针对目标车辆的目标模式的开启指令,获取目标车辆的电池包放电功率;基于电池包放电功率和功率限制系数,对目标车辆的驱动功率进行限制,得到目标可用功率;基于目标可用功率、驱动电机的当前电机转速和目标输出扭矩,确定电机驱动扭矩,目标输出扭矩为目标车辆的驱动电机在当前电机转速下所能输出的扭矩,电机驱动扭矩为限制之后的驱动电机驱动目标车辆行驶的最大输出扭矩。本申请通过对驱动功率的限制来实现对车辆行驶过程中车速的限制,进而降低车辆出现事故的概率,以降低车辆受损的现象,尽可能避免车主财产受到损失。
