<P>PROBLEM TO BE SOLVED: To provide a drive control device that improves responsiveness when a vehicle is started without increasing costs. <P>SOLUTION: The drive control device includes: a torque converter 6 connected to a motor/generator 2; an oil pump 9 to be driven by the motor/generator 2; an accumulator 25 for accumulating the oil pressure generated by driving the oil pump 9; a lock-up clutch 12 that uses the oil pressure accumulated by the accumulator 25, so as to prevent differential rotation of the torque converter 6; and an oil-pressure sensor 32 for detecting the oil pressure accumulated by the accumulator 25. If the oil pressure detected when a vehicle is stopped, is below a predetermined value, the oil pump 9 is driven by the motor/generator 2 while the lock-up clutch 12 is released so as to permit differential rotation of the torque converter 6, thereby allowing the accumulator 25 to accumulate the oil pressure therein. <P>COPYRIGHT: (C)2012,JPO&INPIT |
