Abstract: PROBLEM TO BE SOLVED: To provide a control device of a drive unit for a vehicle which can properly perform the drive control of an engine even at the slip of the vehicle and the non-slip of the vehicle, in the drive unit for the vehicle having a differential mechanism which outputs power from the engine to drive wheels and in which a differential state is controlled by a differentiating electric motor.SOLUTION: A hybrid control means 86 principally controls the engine 8 on the basis of a differential part actual output rotation speed being an actual rotation speed of an output rotating member 19. Then, at the slip of the vehicle 6, the hybrid control means controls the engine 8 on the basis of a vehicle-speed reference output rotation speed corresponding to an actual vehicle speed V in place of the differential part actual output rotation speed. Accordingly, the drive control of the engine 8 can properly be performed so that engine power does not become unnecessarily large at the slip. Furthermore, since the engine 8 is basically controlled on the basis of the actual rotation speed of the output rotating member 19, the drive control of the engine 8 can also properly be performed even at the case other than the slip of the vehicle 6.

Abstract: PROBLEM TO BE SOLVED: To prevent a driver from feeling incongruity when an internal combustion engine is started.SOLUTION: At stop-state starting time when an engine is started in a stop state, when an output limit Wout of a battery is a threshold Wref or less (S120), the engine is started by motoring with adding braking force of a minimum fixing braking force Flomin or more, that is a minimum braking force required for fixing wheels (driving wheels 39a and 39b, and driven wheels) at stop-state starting time by a hydraulic brake (S110, S160 to S200). Thereby, at the stop-state starting time when the output limit Wout of the battery is greatly limited, it is suppressed that the driver feels incongruity by securely fixing the wheels, and discharge power from the battery is reduced by suppressing power consumption of a motor MG2.

Abstract: PROBLEM TO BE SOLVED: To start an engine at more proper timing in a hybrid vehicle with an engine, a motor for outputting power for traveling, and a battery for supplying electric power to the motor. SOLUTION: Power P1 that can be used for traveling from a battery during traveling while stopping an engine and power P2 that can be used for traveling from a battery with engine motoring are calculated (Step S410). Surplus electric power Pmar of the battery is set to be smaller as output limit Wout as the maximum power that can be output from a battery becomes smaller (Step S420). A threshold value for starting Pstart is set based on the power subtracting the surplus electric power Pmar from the power P1 or the power P2 (Step S430). The engine is started when a request power requested for traveling is not less than the threshold value for starting Pstart. Thereby, the engine can be started at more proper timing.

Abstract: PROBLEM TO BE SOLVED: To suppress a risk of over-discharge of a storage device caused by a drop of battery voltage liable to occur due to a decrease of generated output by a motor MG1 or a relative increase of output from a motor MG2 to cope with demand torque required of a driving shaft. SOLUTION: When temporary target charge/discharge electric power Pbtmp based on the residual capacity SOC of a battery is on the charge side (S340), target charge/discharge electric power Pb* is set by multiplying the temporary target charge/discharge electric power Pbtmp by a correction factor α having a tendency to become larger in proportion to the rise of an output fall degree ΔPe which is the falling degree of power output from an engine when operating the engine at a target operating point, with respect to power corresponding to the target operating point (S360, S370). The engine and two motors are then controlled to charge/discharge the battery with electric power based on the target charge/discharge electric power Pb* and to output torque required of the driving shaft, to the driving shaft. The over-discharge of the battery can thereby be suppressed even when the output fall degree ΔPe is comparatively high. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To appropriately set an initial driving condition in selecting a shift position associated with a plurality of driving conditions and allowing a driver to select arbitrary driving condition among the plurality of driving conditions. SOLUTION: A hybrid vehicle 20 sets a tentative first stage SPitmp corresponding to a vehicle velocity V when a driver switches from a D position to an S position (Step S120).
