摘要： First temporary capacity reduction control that when acceleration ON is judged during coasting lock-up, brings lock-up clutch (20) into slip state by decreasing torque transmission capacity of lock-up clutch and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is executed. Control unit performing second temporary capacity reduction control that when return of accelerator pedal depression is judged during the progress of returning to lock-up state, decreases torque transmission capacity again and subsequently returns lock-up clutch to lock-up state by increasing torque transmission capacity is provided. In second temporary capacity reduction control, torque transmission capacity is decreased with predetermined torque transmission capacity by which lock-up clutch is not fully disengaged being lower limit value. Abrupt engagement of lock-up clutch and engine racing can be therefore avoided when acceleration is changed from ON to OFF during control of lock-up clutch from disengagement or slip state to lock-up state.

摘要： A device for controlling a start of a vehicle includes a rotation speed obtaining unit that obtains an actual engine rotation speed of the engine, a target rotation speed computing unit that computes a target rotation speed of the engine in the slip control, a control target value computing unit that computes a control target value, which is a target value for controlling the engine rotation speed to the target rotation speed based on the actual engine rotation speed and the target rotation speed, and an instruction value computing unit that computes an instruction value for the lock-up clutch necessary to control the engine rotation speed to the control target value based on the control target value.
