<p>In this hybrid vehicle (1), which is provided with a hybrid system having the functionality of causing both an internal combustion engine (10) and a motor/generator (20) to be drive sources for vehicle (1) travelling, when solely the regeneration torque (T1) from the motor/generator (20) is sufficient for the target request braking torque (Tt) during deceleration of the hybrid vehicle (1), solely the regeneration torque (T1) resulting from the motor/generator (20) is imparted, and when same is insufficient, braking torque (T2) resulting from compression release braking is generated in addition to the regeneration torque (T1) resulting from the motor/generator (20). Also, when even the sum of the regeneration torque (T1) resulting from the motor/generator (20) and the braking torque (T2) resulting from the compression release braking is insufficient for the target request braking torque (Tt), braking torque (T3) resulting from exhaust braking (12) is added. As a result, it is possible to secure sufficient braking torque during deceleration of the vehicle (1) while using the braking energy as charging energy as much as possible.</p> |
