  • Patent number: 8818627
    Abstract: An object of the invention is to increase the recovered kinetic energy as much as possible in a regeneration control system for a vehicle that converts the kinetic energy of a wheel into electrical energy while the vehicle is decelerating. To achieve the object, in the invention, the electric energy generated by a generator is decreased at the time when the wheel slips. In consequence, the recovered kinetic energy can be made larger as compared to the case where the electric energy generated by the generator is decreased based on an anticipation of slippage of the wheel made in advance.

  • Patent number: 8744677
    Abstract: The present invention is intended to suppress a change in a braking force due to a change in the magnitude of friction of an internal combustion engine, in a regenerative control system for a vehicle in which kinetic energy of wheels is made to be converted (regenerated) to electrical energy, at the time of deceleration running of the vehicle with the internal combustion engine mounted thereon. In order to solve this subject, the present invention is constructed such that the change in friction of the internal combustion engine is offset by adjustment of a regenerative braking force by regulating an amount of excitation current supplied to an electric generator according to the magnitude of friction in the internal combustion engine, at the time of deceleration running of the vehicle.
