    • When a vehicle is decelerating a controller of a motor-generator (2) computes a target charging current according to a charge state of a high voltage battery by a target charging current computing unit (23), and limits this current by a first limiter (24) having a limiter value. An electrical load current supplied to vehicle-mounted electrical loads is computed by an electrical load current detecting unit (27). A target generation current produced by the motor-generator (2) is computed by adding the target charging current and electrical load current, by a target generation current detecting unit (28, 30). This computed value is limited by a second limiter (31) having a limiter value which varies according to an engine rotation speed, ON/OFF state of an air-conditioner and speed ratio. When the vehicle is decelerating the motor-generator (2) is made to function as a generator driven by recovery energy, the high voltage battery and a low voltage battery for the vehicle-mounted electrical loads are charged without overcharging and excessive vehicle deceleration is prevented.
    • 当车辆减速时,电动发电机(2)的控制器根据目标充电电流计算单元(23)根据高压电池的充电状态计算目标充电电流,并且通过第一限幅器( 24)具有限制器值。 通过电力负载电流检测单元(27)计算提供给车载电气负载的电力负载电流。 由目标产生电流检测单元(28,30)通过将目标充电电流和电力负载电流相加来计算由电动发电机(2)产生的目标发电电流。 该计算值由具有根据发动机转速,空调的ON / OFF状态和速度比而变化的限制器值的第二限制器(31)限制。 当车辆减速时,电动发电机(2)作为由恢复能量驱动的发电机起作用,用于车载电力负载的高电压电池和低电压电池被充电而没有过度充电,并且防止了过大的车辆减速 。
