The invention relates to a motor torque control method and device, electronic equipment and a vehicle. The motor torque control method comprises the following steps: determining a correction coefficient based on a resonant frequency when the resonant frequency meets a torque limiting condition in response to the change of driving information of a vehicle; the resonance frequency is used for representing the vibration characteristic of the seat in the target direction, the resonance frequency is determined based on a frequency response function, and the frequency response function is used for reflecting the transmission characteristic of the seat to vibration from a vehicle bottom plate in the vehicle driving process; and according to the correction coefficient, the output torque of the vehicle is corrected, so that the driving comfort is adjusted in real time, the requirement for dynamic balance of the comfort in the vehicle driving process is met, and a guarantee is provided for improving the market competitiveness of the electric vehicle.
本申请涉及一种电机扭矩控制方法、装置、电子设备及车辆。电机扭矩控制方法包括:响应于车辆的行驶信息发生变化,在共振频率满足扭矩限制条件时,基于共振频率确定修正系数;共振频率用于表征座椅在目标方向上的振动特性,共振频率基于频响函数确定,频响函数用于反应车辆行驶过程中,座椅对来自车辆底板的振动的传递特性;根据修正系数,修正车辆的输出扭矩,从而实现对驾乘舒适度的实时调整,满足车辆行驶过程中的舒适性动态平衡要求,为提高电动汽车的市场竞争力提供了保障。
