REGENERATIVE CONTROL DEVICE FOR HYBRID VEHICLE

摘要

A regenerative control device for a hybrid vehicle includes a regenerative braking power control unit prohibiting or limiting execution of first regenerative braking to charge the battery with power generated by the regenerative power generation of the traveling motor generator during deceleration when it is determined that it is necessary to restrict charging of the battery. Under condition where the execution of the first regenerative braking is prohibited or limited, the regenerative braking power control unit causes second regenerative braking to transmit rotary driving power to the engine by rotating the power generation motor generator by the power generated by the regenerative power generation, to be executed when the operation unit is set to a regeneration level in an increasing direction, and causes the second regenerative braking to be stopped when the operation unit is set to a regeneration level in a decreasing direction.
