<P>PROBLEM TO BE SOLVED: To provide an engine start control device that can be quickly started without generating shock caused by an insufficient line pressure, even if a restart request is made during an unintentional release state of a clutch. <P>SOLUTION: The engine start control device includes: a power transmission system including an engine 1 having a driving motor 8 provided thereon and the hydraulically-controlled clutch 11; a mechanical pump 4 that is disposed on the power transmission system to supply a hydraulic pressure; an electric pump 5 connected in parallel to the mechanical pump 4 and independently driven; a hydraulic sensor 6; a means 10a that stops the engine when an idling stop condition is satisfied and starts the engine when a restart condition and a fuel injection condition are satisfied; a means 10c that drives the electric pump when the hydraulic pressure is less than a first hydraulic pressure while the engine is stopped by idling stop; and a means that drives and control a driving motor to become a target speed so that a change in the target speed is small compared with the change exhibited when the hydraulic pressure is equal to or higher than a second hydraulic pressure, when the hydraulic pressure is less than the second hydraulic pressure, and the restart condition is satisfied after the idling stop. <P>COPYRIGHT: (C)2013,JPO&INPIT |
