NOVELTY - The hybrid vehicle (20) has input-output restriction setting unit which sets output and input restrictions as maximum positive and negative electric power that permit discharge and charge of secondary battery (50) based on state and electrical storage ratio of secondary battery, respectively. A correction unit corrects absolute value of output and input restrictions set by input-output restriction setting unit by negative correction value which becomes large, so that ratio difference obtained by subtracting electrical storage ratio from reference electrical storage ratio is large.    USE - Hybrid vehicle.    ADVANTAGE - Charge of the secondary battery by excessive electric power which might arise when a shift position is changed from neutral is suppressed.    DETAILED DESCRIPTION - An electronic control unit (ECU) for engine (24) controls the internal combustion engine (22) and an ECU for motors (40) control electric motors (MG1,MG2) with charging/discharging of the secondary battery by electric power within the range of the set output and input restrictions. A reference electrical storage ratio setting unit sets the set electrical storage ratio as reference electrical storage ratio for every predetermined time, when the output restriction set by the input-output restriction setting unit is not zero value or less, maintains the set reference electrical storage ratio, wen the output restriction set by the input-output restriction setting unit has zero value or less, and a shift position is not neutral. and sets the value which adds ratio variation obtained by subtracting electrical storage ratio before being set for predetermined time from electrical storage ratio, to the set reference electrical storage ratio, as a new reference electrical storage ratio, when a shift position is neutral.
