The invention discloses a motor controller and an electric automobile, the motor controller comprises a main control chip, a power supply chip, a turn-off path module, a drive circuit module and an IGBT power module, the power supply chip is connected with the main control chip, and the power supply chip is used for providing a low-voltage power supply for the main control chip; the main control chip, the turn-off path module, the driving circuit module and the IGBT power module are connected in sequence, and the main control chip is used for obtaining multiple sets of recovery signals and controlling the driving circuit module to output corresponding driving signals through the turn-off path module according to the multiple sets of recovery signals so as to control the IGBT power module to enter a corresponding safety mode. Therefore, on the basis that the hardware structure of the motor controller is not changed, the corresponding driving signals are generated according to the multiple sets of recovery signals so as to control the IGBT power module to enter the corresponding safety mode, and therefore the safety and reliability of the motor controller are ensured while the manufacturing cost of the whole vehicle is prevented from being increased, and the driving experience of a user is improved.

    本发明公开了一种电机控制器和电动汽车,其中,电机控制器包括:主控芯片、电源芯片、关断路径模块、驱动电路模块、IGBT功率模块,其中,电源芯片与主控芯片相连,电源芯片用于为主控芯片提供低压供电电源;主控芯片、关断路径模块、驱动电路模块和IGBT功率模块依次相连,主控芯片用于获取多组回采信号,并根据多组回采信号通过关断路径模块控制驱动电路模块输出相应驱动信号,以控制IGBT功率模块进入相应的安全模式。由此,在不改变电机控制器硬件结构的基础上,根据多组回采信号生成相应的驱动信号,以控制IGBT功率模块进入相应的安全模式,从而在避免整车制造成本增加的同时,确保电机控制器的安全可靠性,提升用户的驾乘体验。
