- FIG. 6 is a flowchart for explaining a main part of the control operation of the electronic control unit 10, that is, a control operation for automatically starting the engine 12 according to the engine automatic start request while the engine is stopped and the motor is running.
- This flowchart is repeatedly executed with an extremely short cycle time of, for example, about several milliseconds to several tens of milliseconds when the engine is stopped and the motor is running.
- step S1 corresponding to the engine automatic start determination means 90, it is determined whether or not a predetermined engine automatic start condition is satisfied. In this embodiment, it is determined that the engine automatic start condition is satisfied when at least one of the motor travel permission conditions is not satisfied.
- the engine rotational speed N E which is, for example, be started by the first electric motor speed N M1 is energized to the first electric motor M1 is raised
- the engine 12 is started by being raised to a predetermined rotational speed, for example, an idle rotational speed NEIDL or more, supplied with fuel by the fuel injection device 84 and ignited by the ignition device 86.
- the differential limiting clutch (differential Since the limiting device 94 includes the engine starting differential limiting means 94 that limits the differential rotation between the front driving wheel (first driving wheel) 30 and the rear driving wheel (second driving wheel) 32 by the CL, the differential limiting is included. A state in which the play that exists in the power transmission path between the engine 12 and the front drive wheels 30 and the rear drive wheels 32 is packed due to the differential restriction between the front drive wheels 30 and the rear drive wheels 32 by the clutch CL.
- the engine Since the engine is started at this time, it is possible to easily suppress the noise generated when the engine is running, that is, the rattling noise caused by the rattling, at a low cost. That is, when the differential limiting torque TL is applied to the differential limiting clutch CL when the engine is started, a vehicle driveline (power) is generated by a slight diameter difference, that is, a rotational difference between the front drive wheels 30 and the rear drive wheels 32. As the circulating torque is generated in the transmission path), the backlash of the mesh such as a spline is reduced, so that even if a torque change occurs when the engine is started, the generation of abnormal noise due to the backlash is preferably prevented.
- the engine starting differential limiting means 94 calculates the driving torque T that fluctuates when the engine 12 is started by the engine automatic start control means 92 and is stored in advance. From the above relationship, based on the calculated drive torque T, as the drive torque T increases, the limiting force for differential rotation between the front drive wheel 30 and the rear drive wheel 32, that is, the differential limit torque TL increases. Therefore, the power transmission path between the engine 12 and the front drive wheels 30 and the rear drive wheels 32 is loosened by the minimum necessary differential restriction by the differential restriction clutch CL. Therefore, it is possible to suppress the drivability and the fuel consumption from being lowered by performing the differential limitation by the differential limiting clutch CL more than necessary.
