Vehicle control system and vehicle control method

The invention provides a control system for a vehicle. The vehicle comprises a three-phase AC motor, a first switching element, a second switching element and an electric power converter. The control system comprises a shortcircuit detector and an ECU. The ECU is configured in manners of (a) when vehicle stopping is determined, controlling the electric power converter so that the electric power converter is in a preset state in which one member in the first switching element and the second switching element is in the off state for aiming at totally phase in the three phases, and (b) when the shortcircuit detector detects shortcircuit in one member in the first switching element and the second switching element, controlling the electric power converter so that the switching element in which shortcircuit is detected is in an on state in a preset state. 提供种用于车辆的控制系统，该车辆包括三相AC电动机、第开关元件、第二开关元件以及电力转换器。控制系统包括短路检测器和ECU。将ECU配置成：(a)当判定车辆停止时，控制电力转换器，以便使电力转换器处于预定状态，在该预定状态中第开关元件和第二开关元件中的者针对三相中的全部相处于关断状态，以及(b)当短路检测器在第开关元件和
