Since the target engine torque is set so that the operating point of the engine 1 is on the high-efficiency engine torque line, good fuel efficiency and exhaust performance are also ensured.
- FIG. 9 is a diagram for explaining the contents of the control in the power generation mode.
- the generated torque of the motor generator 4 is controlled to the target motor torque, which is a value obtained by subtracting the engine no-load torque (the torque required to rotate the engine itself) from the target engine torque.
- the power generation torque of the motor generator 4 is not gradually increased stepwise to the target power generation torque as shown by the dotted line in FIG. 8, but is gradually increased over a predetermined transient time as shown by the solid line.
- the change in the load (power generation torque) of the engine 1 becomes gradual, and disturbance of the engine rotation speed can be avoided, so that power generation can be performed stably without deteriorating the exhaust performance.
- an idle stop that stops the operation of the engine 1 is executed. Obtainable. Since the S0C of the power storage device 9 is sufficient, the vehicle can be started only by the output of the motor generator 4 at the time of restart, and the opportunity of starting only by the output of the motor generator 4 is not reduced.
- control system is composed of a plurality of controllers.
- the number of controllers may be larger or smaller, and the control system may be composed of one controller.
- the present invention can be applied to a parallel hybrid vehicle having an engine and a motor generator as drive sources of the vehicle, and is useful for improving starting performance, fuel consumption performance, and exhaust performance.
