    摘要: A control system is provided for a hybrid vehicle with an engine, a motor, and a power storage unit. The control system comprises: an assist trigger threshold value setting device for setting a throttle opening state when the motor starts assist for the output from the engine; a throttle opening state lower limit setting device for setting a lower limit by subtracting a predetermined value from the threshold value obtained by the assist trigger threshold value setting device; a generation reduction device for gradually reducing the generation by the motor between the lower limit and the threshold value so that the generation finally becomes zero when the present throttle opening state reaches the threshold value, when the vehicle shifts from a generation state, in which the motor acts as a generator and the output is supplied only from the engine, to an output assist state in which the motor assists the output.

    摘要: A hybrid vehicle control apparatus for improving fuel consumption ratio by making appropriate the deceleration perception of the hybrid vehicle is provided. It is determined whether the flag setting of a brake ON determination flag is “1”. If the brake is OFF, a brake OFF regeneration amount is obtained, and is assigned to the deceleration regeneration computed value. It is determined whether a remaining batter charge is greater than or equal to a predetermined normal power generation mode execution upper limit remaining charge. In the case where the determination result is yes, it is determined whether a control vehicle speed is greater than or equal to a predetermined high speed deceleration regeneration reduction lower limit vehicle speed. In the case where the determination result is yes, the value obtained by multiplying the deceleration regeneration computed value by a predetermined high speed deceleration regeneration reduction coefficient, for example 0.8, is set as a new deceleration regeneration computed value.
