The invention relates to a motor driving circuit, a vehicle and a chip, the motor driving circuit comprises a safety mode selection circuit, a first control module, a second control module and a driving module, the safety mode selection circuit is connected with the first control module, the second control module and the driving module, and the driving module is used for being connected with a motor. The first control module is used for operating a pre-configured protection mode selection program, and the second control module acquires system operation data; the safety mode selection circuit is used for generating a target mode selection signal according to the system operation data and inputting the target mode selection signal to the driving module under the condition of determining that the first control module fails; and the driving module controls the motor to enter the target safe operation mode according to the target mode selection signal. Thus, under the condition that it is determined that the first control module breaks down, the target safe operation mode matched with the current working condition of the motor driving system can be switched through the hardware circuit, and therefore the safety and stability of the motor driving system can be effectively improved.

    本公开涉及一种电机驱动电路、车辆及芯片,电机驱动电路包括,安全模式选择电路,第一控制模块,第二控制模块以及驱动模块,安全模式选择电路与第一控制模块、第二控制模块和驱动模块连接,驱动模块用于连接电机,第一控制模块用于运行预先配置的保护模式选择程序,第二控制模块获取系统运行数据;安全模式选择电路,在确定第一控制模块故障的情况下,根据系统运行数据生成目标模式选择信号,输入至驱动模块;驱动模块,根据目标模式选择信号控制电机进入目标安全运行模式。这样,能够在确定第一控制模块故障的情况下,通过硬件电路切换到与电机驱动系统当前工况相匹配的目标安全运行模式,从而能够有效提高电机驱动系统的安全性和稳定性。
