The invention relates to the technical field of vehicles, in particular to a control method and device of an electric drive system, an electric drive controller and a vehicle. The method comprises the steps that the current rotating speed requirement and/or the current torque requirement of the vehicle are/is obtained; if the current rotating speed demand and/or the current torque demand do/does not meet the current response capability of the electric drive system, the current rotating speed demand and/or the current torque demand are/is adjusted based on the current response capability of the electric drive system; and sending the adjusted current rotating speed demand and/or the adjusted current torque demand to a motor controller MCU, and receiving fault information reported by the MCU when the adjusted current rotating speed demand and/or the adjusted current torque demand do not meet the current response capability of the electric drive system. Therefore, the problems that the VCU and the MCU do not judge the output signal and report a motor fault, a user is misguided to replace the motor and the like are solved, the response of a wrong instruction is effectively avoided, the reliability is improved, and the complaint of the user is reduced.
本申请涉及车辆技术领域,特别涉及一种电驱系统的控制方法、装置、电驱控制器及车辆,其中,方法包括:获取车辆的当前转速需求和/或当前扭矩需求;若当前转速需求和/或当前扭矩需求不满足电驱系统的当前响应能力,则基于电驱系统的当前响应能力,调节当前转速需求和/或当前扭矩需求;将调节后的当前转速需求和/或调节后的当前扭矩需求发送至电机控制器MCU,并接收MCU在调节后的当前转速需求和/或调节后的当前扭矩需求不满足电驱系统的当前响应能力上报的故障信息。由此,解决了VCU和MCU未进行输出信号的判断而上报电机故障,误导用户更换电机等问题,有效地避免了错误指令的响应,增加可靠性,减少用户抱怨。
