Abstract: PROBLEM TO BE SOLVED: To provide a vehicle control device that can execute slip start control in which a lock-up clutch is put in a semi-engaged state during the start of a vehicle, and which suppresses the generation of a shock during the slip start control.SOLUTION: When the generation of the vibration of output shaft torque is determined due to the excess gripping of the lock-up clutch during the slip start control at the start of the vehicle, the control pressure of the lock-up clutch is reduced by learning at a side where an instruction value of a lock-up control pressure is reduced (updating a learning value so that the lock-up control pressure is made to be a depressurization side). The learning control can reduce the instruction value of the lock-up control pressure when the torque vibration caused by the dispersion of the hardware of an SLU solenoid valve actually occurs. Consequently, the shock during the start of the vehicle can be prevented while securing a fuel consumption effect by the slip start control.
