Abstract
A control system for a vehicle including a three-phase AC motor, a first switching device, a second switching device, and a power converter, is provided. The control system includes a short-circuit detector, and an ECU. The ECU is configured to: (a) control the power converter, when it is determined that the vehicle is stopped, so as to place, the power converter in a predetermined condition in which one of the first switching device and the second switching device for all of the three phases is in an OFF state, and (b) control the power converter when the short-circuit detector detects a short circuit in one of the first switching devices and the second switching devices, so that said one of the first and second switching devices in which the short circuit is detected provides the ON state in the predetermined condition.
