本发明公开了一种电动汽车用驱动主动短路的控制方法和装置,其中所述控制方法包括以下步骤:PDU控制器同步输出主动短路安全状态使能信号和PDU继电器关断信号;通过PDU继电器关断信号使电机控制系统退出升压充电模式;电机控制系统退出升压充电模式后,通过主动短路安全状态使能信号使电机控制系统进入主动短路安全状态。本发明解决了升压充电模式下电机控制器由于故障误进入主动短路安全状态,造成驱动模块损坏的风险。
Disclosed is a control method of driving active short circuit for electric vehicles, including the following steps: outputting, by a power distribution unit, PDU controller, an active short circuit safety state enable signal and a PDU relay shut-off signal synchronously; in response to that the vehicle fails in a boost charging mode, making a motor control system exit the boost charging mode through the PDU relay shut-off signal; and after the motor control system exits the boost charging mode, making the motor control system enter an active short circuit safety state through the active short circuit safety state enable signal. The present application futher relates to an apparatus for driving active short circuit for electric vehicles. In practical application, the risk of a driving module being damaged caused by an electric motor controller in a boost charging mode entering an active short-circuit safety state by mistake due to a fault is solved.
