In various embodiments, there is provided a method for reducing vibrations of a body (1) of an electric vehicle by means of an electric machine (4) of the vehicle, the method comprising: determining vibrations of a subframe (2) or vibrations of the body (1) in a region of a force introduction location via the subframe (2), wherein the motor (4) is supported on the vehicle body (1) or the auxiliary frame (2); determining a torque which is required to be generated by the electric motor (4) in order to introduce forces into the subframe (2) or the body (1), said forces counteracting forces which are caused by the determined vibrations and which act on the subframe (2) or the body (1); and adjusting at least one drive signal of the electric machine (4) on the basis of a change in the drive torque of the electric machine (4) such that the desired torque is generated. An electric vehicle configured to perform the method according to the invention is also provided.
在各种实施方案中,提供了一种用于借助于电动车辆的电机(4)来减小所述车辆的车身(1)的振动的方法,所述方法包括:确定副车架(2)的振动或所述车身(1)在经由所述副车架(2)的力引入部位的区域中的振动,其中所述电机(4)支承在所述车身(1)上或所述副车架(2)上;确定为了将力引入到所述副车架(2)或所述车身(1)中而需要由所述电机(4)产生的扭矩,所述力抵消由所确定的振动引起的并且作用在所述副车架(2)或所述车身(1)上的力;以及基于所述电机(4)的驱动扭矩的变化,调节所述电机(4)的至少一个驱动信号,使得产生所需扭矩。还提供了一种被配置为执行根据本发明的方法的电动车辆。
