The embodiment of the invention discloses a motor torque determination method which is used for determining the motor torque of a vehicle, a motor is used for driving a transmission in the vehicle, and the method comprises the steps that the current noise frequency spectrum and the current corresponding relation of gears of the transmission when the vehicle is driven at variable speed under the preset working condition are obtained, and the current corresponding relation is obtained according to the current noise frequency spectrum; determining the current sound pressure level of the gear and the current sound pressure level of the background, determining the current protruding amount of the current sound pressure level of the gear relative to the current sound pressure level of the background, and when the current protruding amount is larger than a preset protruding amount threshold value, determining the current sound pressure level of the gear based on the running speed corresponding to the protruding amount larger than the preset protruding amount threshold value in the current corresponding relation. And the to-be-adjusted running speed is determined, the motor torque corresponding to the to-be-adjusted running speed is adjusted to obtain the current corresponding relation again, and the current corresponding relation is determined as the target corresponding relation of the vehicle under the preset working condition. The embodiment of the invention also provides a motor torque determination device, vehicle-mounted equipment and a computer storage medium.

    本发明实施例公开了一种电机扭矩的确定方法,该方法用于确定车辆的电机扭矩,电机用于驱动车辆中的变速器,包括:获取车辆在预设工况下变速行驶时变速器的齿轮的当前噪声频谱和当前对应关系,根据当前噪声频谱,确定齿轮的当前声压级和背景的当前声压级,确定齿轮的当前声压级相对于背景的当前声压级的当前凸出量,当当前凸出量大于预设凸出量阈值时,基于当前对应关系中大于预设凸出量阈值的凸出量对应的行驶速度,确定待调整行驶速度,调整待调整行驶速度对应的电机扭矩,以重新得到当前对应关系,将当前对应关系确定为车辆在预设工况下的目标对应关系。本发明实施例还同时提供了一种电机扭矩的确定装置、车载设备和计算机存储介质。
