Patent ID: 7997363

Claim:
A vehicle control system comprising: a storage battery unit connected to vehicle-mounted devices to feed electric power to the vehicle-mounted devices; a charging condition detection unit for detecting a charging condition of the storage battery unit; a torque actuator including an internal combustion engine and a generator that generates electricity by using a torque of an output shaft of the internal combustion engine and electrically charges the storage battery unit; and a driver-required wheel torque calculation unit for calculating a driver-required wheel torque; a correction wheel torque calculation unit for estimating vibrating conditions of a vehicle, and calculating a correction wheel torque for the driver-required wheel torque to decrease vibrations of the vehicle; a target wheel torque calculation unit for calculating a target wheel torque based on the driver-required wheel torque and the correction wheel torque; a required output shaft torque calculation unit for calculating a required output shaft torque, which is to be generated by the torque actuator, based on the target wheel torque; a battery-required generator torque calculation unit for calculating a battery-required generator torque required to generate electric power for maintaining a predetermined base amount of the electric power by monitoring an amount of electric power stored in the storage battery unit; a torque division unit for dividing the required output shaft torque into a low frequency component and a high frequency component and calculating a target engine torque and a target generator torque, the target engine torque being calculated as a difference between the low frequency component and the battery-required generator torque, and the target generator torque being calculated as a sum of the high frequency component and the battery-required generator torque; a torque actuator control unit for controlling the internal combustion engine and the generator to realize the target engine torque and the target generator torque by the internal combustion engine and the generator, respectively.
