Abstract:
1. A device for controlling a start of a vehicle in which an output of a driving force source is output from a transmission via a torque converter including a lock-up clutch, the device comprising: a start request detection unit adapted to detect a start request for the vehicle; a hydraulic pressure control circuit adapted to control torque transmitted by the lock-up clutch by controlling an engagement force of the lock-up clutch when the vehicle starts; a rotation speed detection unit adapted to detect an output rotation speed of the torque converter; an elapse wait unit adapted to wait until a predetermined time period elapses since detection of the start request by the start request detection unit; an increase wait unit adapted to wait until the output rotation speed of the torque converter increases to a predetermined rotation speed or higher when the vehicle starts; and an engagement control unit adapted to issue an instruction to the hydraulic pressure control circuit such that the lock-up clutch is placed in slip engagement and is able to transmit the torque when the following conditions are both satisfied: the predetermined time period has elapsed since detection of the start request by the start request detection unit; and the output rotation speed has increased to the predetermined rotation speed or higher.
