摘要:
In a fuel cell system, regeneration-time voltage fixed control is implemented where during regeneration or when regeneration is expected to occur, output voltage of a fuel cell is set to a voltage value outside an oxidation reduction progress voltage range, and the amount of reactant gas supplied to the fuel cell is changed based on the amount of electric power remaining in an energy storage device. In the regeneration-time voltage fixed control, it is determined whether or not regeneration occurs while a moving body equipped with the fuel cell system is moving down a slope, and in the case where it is determined that regeneration occurs while the moving body is moving down a slope, the amount of the reactant gas supplied to the fuel cell is decreased in comparison with the case where it is determined that regeneration occurs while the moving body is not moving down a slope.

According to the present invention, information which is associated with a motion of a vehicle can be acquired even in the case where no vehicle travels on a road. Motion information, which is associated with the motion of the vehicle on the road where the vehicle traveled, is acquired along with time information. Reference traffic information, which is traffic information on the road at a reference time which is specified by the time information, is acquired from a traffic information providing device which constantly provides the traffic information. A correlation between the motion information and the reference traffic information is specified. Furthermore, estimated motion information, which indicates an estimated motion of the vechicle on the road at an estimate time when the motion is estimated, is acquired based on estimating source traffic information at the estimate time and the correlation, the estimating source traffic information being provided as the traffic information of the estimating source from the traffic information providing device in the case where no motion information is acquired at the estimate time.

An electric vehicle includes a device which determines, on the basis of the gradient of a road surface, a target acceleration of the vehicle in the case where the operational states of an accelerator (gas) pedal and a brake pedal of the vehicle are an OFF state when the vehicle is traveling on a down-slope road, a device which determines the correction amount of a regenerative torque for bringing the actual acceleration of the vehicle close to the target acceleration, a device which determines a basic target torque of an electric motor, which becomes a regenerative torque when the operational state of the accelerator (gas) pedal is the OFF state, on the basis of the operational state of the accelerator (gas) pedal, and a device which determines a target torque by correcting the basic target torque on the basis of at least the aforesaid correction amount. The output torque of the electric motor is controlled to the determined target torque. Thus, when the electric vehicle travels on the down-slope road, the regenerative operation of the electric motor is accomplished such that an acceleration suited to the gradient of the road surface can be generated in the vehicle while minimizing the influences of disturbance factors.
