Control device for vehicle

A control device for a vehicle comprising:

• an engine stop and start device configured to perform an automatic stop and a restart of an engine, which is a power source for the vehicle;
• a battery configured to supply electric power to the engine stop and start device;
• a vehicle speed detecting unit configured to detect speed of the vehicle;
• a battery current detecting unit configured to detect an electric current of the battery;
• a battery temperature detecting unit configured to detect temperature of the battery;
• a deceleration state detecting unit configured to detect a deceleration state of the vehicle;
• a fuel supply stop unit configured to stop fuel supply to the engine when the deceleration state detecting unit detects that the vehicle is in the deceleration state;
• an average charging current calculating unit configured to calculate an average of a battery current detected by the battery current detecting unit;
• and
• an SOC estimating unit configured to estimate an SOC of the battery from an average charging current and calculate an estimated SOC, wherein
• the control device calculates, with the average charging current calculating unit, an average of a battery current in a predetermined time from detection of a stop of the fuel supply to the engine in the deceleration state of the vehicle and permits a stop of the engine when the SOC calculated by the SOC estimating unit is larger than a predetermined value.
