Abstract:
1. A control system for a vehicle having an electric power generator, an electric power storage unit, a drive motor driven by electric power supplied from at least one of the electric power generator and the electric power storage unit, and drive wheels driven by drive power supplied from the drive motor, the control system comprising: a demanded drive power calculating section calculating a demanded drive power required for driving the vehicle; an allowable drive electric power output calculating section calculating allowable drive electric power output of the electric power storage unit required for compensating a delayed response of the electric power generator with respect to a variation in the demanded drive power; an available electric power output calculating section calculating available electric power output of the electric power storage unit to be outputted on the basis of a state of charge of the electric power storage unit, the available electric power output being electric power outputable from the electric power storage unit; and a target electric power output calculating section calculating to be produced from the electric power generator on the basis of the demanded drive power, the allowable drive electric power output of the electric power storage unit and the available electric power output of the electric power storage unit, wherein the control system controls the electric power storage unit on the basis of the allowable drive electric power output and the available electric power output, and the electric power generator on the basis of the target electric power output so as to control the vehicle correspondingly to the demanded drive power.
