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.
