PROBLEM TO BE SOLVED: To provide a control device for vehicle which has suppressed lowering of acceleration feeling at the friction start time.SOLUTION: A control device for vehicle for performing a friction start includes: target value setting means for setting a power source rotational frequency target value from an accelerator opening; slip control means for performing slip control for controlling a hydraulic pressure so that a rotational frequency difference occurs in engagement elements at the start; and rotational frequency prediction means for calculating prediction rotational frequency of an output shaft for performing slip control in which the rotational frequency of the power source can be maintained substantially at the power source rotational frequency target value, in the case where synchronization is performed to make the rotational frequency difference of the engagement elements zero before the start. The slip control means makes the hydraulic pressure of the slip control a value at which the rotational frequency of the power source can be maintained substantially at the power source rotational frequency target value before a measurement value of the rotational frequency of the output shaft surpasses the prediction rotational frequency, and after the prediction rotational frequency of the output shaft has surpassed the prediction rotational frequency, increases the hydraulic pressure of the slip control, and starts synchronization control so that the rotational frequency difference of the engagement elements becomes zero.SELECTED DRAWING: Figure 3 |
