Abstract:
1. A control device for a vehicle, said vehicle including a rotating electric machine, a power storage device for supplying electric power to said rotating electric machine, and a relay for switching a state of an electric power supply line connecting said power storage device and said rotating electric machine to each other between a conducting state and an interrupted state, said control device comprising: a vehicle control unit for putting the state of said electric power supply line into said interrupted state when a first condition on a state of said vehicle is satisfied; a state of charge detecting unit for, in parallel with an operation of said vehicle control unit, detecting a state of charge of said power storage device and transmitting detected said state of charge to said vehicle control unit and for putting the state of said electric power supply line into said interrupted state when a second condition on the state of said power storage device is satisfied; and a power supply interrupting unit for putting the state of said electric power supply line into said interrupted state with said relay in response to a request from at least either one of said state of charge detecting unit and said vehicle control unit, said second condition is a condition that an abnormality occurs in said power storage device, and said state of charge detecting unit requests that the state of said electric power supply line be put into said interrupted state after standby time has elapsed since the state of said electric power supply line was switched by said relay from said interrupted state to said conducting state when said second condition is satisfied during startup of said vehicle.
