Claim:
1. An electric power conversion control device for a vehicle, equipped on a vehicle including an electric power system that has an electric power converter for performing electric power conversion via the switching of a switching element, and supplies electrical power from the electric power converter to a rotation machine, said electric power conversion control device for a vehicle comprising: a switching control unit configured to control performance of the switching; an overvoltage abnormality detection unit configured to detect an overvoltage abnormality of the electric power system; and a collision detection unit configured to detect collision of the vehicle, wherein when the overvoltage abnormality detection unit detects an overvoltage abnormality, and the collision detection unit detects that the vehicle is not in collision, the switching control unit stops performance of the switching, and in a case where the overvoltage abnormality detection unit detects an overvoltage abnormality, and the collision detection unit detects that the vehicle is in collision, and when a voltage of the rotating machine or the electric power system exceeds an allowable value, the switching control unit stops performance of the switching, and in a case where the overvoltage abnormality detection unit detects an overvoltage abnormality, and the collision detection unit detects that the vehicle is in collision, and when a voltage of the rotating machine or the electric power system is the allowable value or less, the switching control unit performs the switching and increases the allowable value with an increase in the amount of time elapsed after the collision detection unit detects collision of the vehicle.
