摘要： PROBLEM TO BE SOLVED: To appropriately suppress drive torque fluctuation occurring due to a reaction force when rotationally driving and starting an engine by a first motor generator MG1 of an electric type differential part by using a second motor generator MG2 connected to a power transmission path at a rear wheel side. SOLUTION: A clutch CL capable of connecting the two rotating elements (CS, CR) of three rotating elements (CS, CCA, CR) of a front and rear wheel power distribution device 14 is provided, and the clutch CL is engaged when an engine 20 is rotationally driven and started by the MG1, so that it is possible to appropriately accept the reaction force by the MG2 to suppress drive torque fluctuation. When the clutch CL is engaged, a difference between front and rear wheels 44 and 34 is restricted and there is the possibility of the occurrence of a tight corner braking phenomenon or the like. However, when a steering angle Φ is equal to or more than a prescribed value, the start of the engine 20 is stopped, so that the occurrence of the tight corner braking phenomenon or the like during turning travel due to the start control of the engine 20 is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a control device of a vehicle capable of suppressing a vibration in starting at a high steering angle.
SOLUTION: An ECU executes a program including a step (S100) which detects a throttle opening, a vehicle speed, the gear step of a transmission, a steering angle, and an acceleration in the longitudinal direction of a vehicle, as the information required for determining whether or not it is necessary to control a control clutch of a control coupling, and a step (S400) which applies an engagement torque to the control clutch when it is determined that it is necessary to control the control clutch (YES at S200) since there is a possibility of occurrence of a stick slip when the steering angle is larger than a predetermined steering angle and the vehicle is in starting.
