  • Electric generation control system for hybrid vehicle
    Patent number: 5614809
    Abstract: When the remaining capacity of a battery on a hybrid vehicle is smaller than a threshold value or the battery is unable to output the amount of electric energy required to propel the hybrid vehicle with a propulsive electric motor, the engine is started by a generator which operates in a motor mode. After the engine has been warmed up, the generator operates in a generator mode to generate electric energy which is supplied to the battery and the propulsive electric motor. The threshold value for the remaining capacity of the battery is greater as the atmospheric pressure is lower. Therefore, if the hybrid vehicle is running under a low atmospheric pressure such as on a highland, the electric energy is supplied from the generator to the battery and the propulsive electric motor at an early stage where the capacity of the battery is relatively high.
