The invention relates to the technical field of vehicle motor control, and discloses a vehicle, a vehicle motor controller and a control method thereof. A main control module; a driving module and an I-GBT module, wherein the driving module is connected with the I-GBT module; the logic circuit module and the rotating speed detection module are also connected with a three-phase voltage circuit of the motor controller; the rotating speed detection module is used for acquiring a voltage signal of a three-phase voltage line, outputting a first electric signal when the current vehicle speed is greater than a preset vehicle speed, and outputting a second electric signal when the current vehicle speed is less than or equal to the preset vehicle speed; when the main control module is in a preset fault state, the power management module outputs a low-level signal, and the logic circuit module controls the driving module to enter a safe state mode according to the low-level signal and the first electric signal. Therefore, when the master control module is in the preset fault state, the master control module can enter the safety mode to protect the safety of the motor controller. Based on the setting of the rotating speed detection mode, the generation of unexpected braking torque in a low-speed region can be avoided.

    本申请涉及车辆电机控制技术领域,公开了一种车辆、车辆的电机控制器及其控制方法,包括:电源管理模块;主控模块;驱动模块及I GBT模块,驱动模块与I GBT模块连接;逻辑电路模块及转速检测模块,转速检测模块还与电机控制器的三相电压线路连接;转速检测模块用于获取三相电压线路的电压信号,在当前车速大于预设车速时输出第一电信号,小于等于预设车速时输出第二电信号;主控模块处于预设故障状态时,电源管理模块输出低电平信号,逻辑电路模块根据低电平信号与第一电信号控制驱动模块进入安全状态模式。因此,主控模块处于预设故障状态时,能够进入到安全模式,以保护电机控制器的安全。基于转速检测模式的设置,能避免在低速区产生非预期制动扭矩。
