The invention provides a vehicle active noise reduction method and device, electronic equipment and a storage medium. And in the running process of the automobile, the target amplitude is searched in the mapping relation between the preset target amplitude and the motor rotating speed through the current motor rotating speed, and a noise reduction signal is generated based on the current motor frequency, the target amplitude and the reverse motor phase, so that the order noise of the gear is counteracted, and active noise reduction is carried out on the automobile. According to the mode, torque distribution of a front electric drive system and a rear electric drive system does not need to be adjusted, the corresponding noise spectrum is inquired according to the current rotating speed of the motor, the anti-phase noise reduction signal is played for active noise reduction, and in this way, the howling suppression effect can be improved under the heavy load condition. The torque distribution of the front and rear electric drive systems does not need to be adjusted, so that the driving safety is not influenced.
本发明提供一种车辆主动降噪方法及装置、电子设备、存储介质。在汽车行驶过程中,通过当前电机转速,在预先设定的目标幅值与电机转速之间映射关系中查找目标幅值,基于当前电机频率、目标幅值和反向的电机相位生成降噪信号,以抵消齿轮的阶次噪声,以对车辆进行主动降噪。这种方式不需要通过调节前后电驱系统的扭矩分配,而是根据当前电机转速查询对应的噪音频谱,播放反相降噪信号进行主动降噪,这样在重载的情况,能够提高对啸叫的抑制效果。由于本发明不需要调节前后电驱系统的扭矩分配,从而也不会影响驾驶安全。
