An ECU is configured to determine the life of a pressure storage tank. The pressure storage tank has a gas chamber filled with gas, an oil chamber connected to a common passageway, and a piston dividing the gas chamber and the oil chamber. The pressure storage tank is configured to store hydraulic oil in the oil chamber and to release the hydraulic oil from the oil chamber. The ECU calculates a movement amount of the piston based on the volume change of the gas chamber. The ECU determines that the life of the pressure storage tank has ended when an integrated value of the calculated movement amount exceeds a threshold value.

A control device of a vehicle is installed in a vehicle including: a body having a vehicle cabin and a floor panel constituting a floor of the vehicle cabin; a door opening-closing mechanism that drives a door mounted on the body to open and close; and a slope deploying mechanism that deploys a slope plate housed under the floor panel to the outside of the body. The control device coordinates the operation of the door opening-closing mechanism and the slope deploying mechanism. The control device opens the door by the door opening-closing mechanism after deploying the slope plate toward the outside of the body by the slope deploying mechanism.
