To maintain and improve the durability by suppressing deterioration of a battery while ensuring as large a use area as much as possible of the capacity of the battery mounted on a vehicle.
A control device for a vehicle has an upper limit value of the remaining battery capacity at traveling (H1) that is set when the vehicle is traveling and an upper limit value of the remaining battery capacity at parking (H2) that is lower than the upper limit value of the remaining battery capacity at traveling (H1) and is set when the vehicle is parking, as upper limit values of the remaining battery capacity. According to the traveling state of the vehicle, the control device for a vehicle switches between the upper limit value of the remaining battery capacity at traveling (H1) and the upper limit value of the remaining battery capacity at parking (H2). When parking, the upper limit value of the battery capacity is controlled so that it may be within a range that can suppress the progress of deterioration, and when traveling, the battery capacity can be used in a wide range to secure enough traveling performance of the vehicle. Thereby, the battery capacity can be efficiently used and the deterioration of the battery can be suppressed when the vehicle is left unused for a long time period.
