The invention is suitable for the technical field of automobiles, and provides a torque adjusting method and device of a vehicle motor, a vehicle-mounted terminal and a computer readable storage medium, and the method comprises the steps that the current temperature of a front axle motor of a vehicle is obtained; as the front axle motor is close to the fuel cell engine, heat dissipation of the front axle motor is difficult due to electric pile heat radiation, and therefore when it is detected that the current temperature meets the set condition, the first torque value of the rear axle motor of the vehicle is determined according to the preset standard temperature of the front axle motor; and the torque of the rear axle motor is adjusted based on the first torque value, and at the moment, when the total torque requirement of the whole vehicle is not changed, the torque of the front axle motor is also changed, so that the current temperature of the front axle motor is close to the standard temperature. Compared with the prior art that heat dissipation is conducted by adjusting the rotating speed of a cooling fan, the influence of driving equipment of the vehicle on automobile heat management in the running process of the vehicle is considered, and therefore the control accuracy of heat management is improved.
本申请适用于汽车技术领域,提供了一种车辆电机的扭矩调整方法、装置、车载终端及计算机可读存储介质,所述方法包括:获取车辆的前桥电机的当前温度;由于前桥电机距离燃料电池发动机较近,电堆热辐射导致前桥电机散热困难,因此,当检测到当前温度满足设定条件时,根据预设的前桥电机的标准温度确定车辆的后桥电机的第一扭矩值;基于第一扭矩值对后桥电机的扭矩进行调整,此时,在整车的总扭矩需求不变时,前桥电机的扭矩也得到改变,使得前桥电机的当前温度向着标准温度贴近。与现有技术通过调整冷却风扇转速进行散热相比,本申请考虑到车辆在运行过程中时,车辆的驱动设备对汽车热管理的影响,从而提高了对热管理的控制准确率。
