Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an engine controller capable of ensuring oil pressure securely and reducing time loss when engaging a clutch. SOLUTION: This vehicle controller has a CVT 4 for shifting gear for driving force from an engine 1 and transmitting it, a mechanical oil pump 11 for supplying hydraulic fluid using the engine 1 as a driving source, and an advancing and backing clutch 3 for controlling transmission of driving force from the driving source to the CVT 4 and is provided with the engine 1 and a motor/generator 15 as the driving source. Lower limit guard is set to target rotational speed of the engine 1 to satisfy required rotational speed of the engine 1 for letting the mechanical oil pump 11 discharge hydraulic fluid. Consequently, a hydraulic pump of the mechanical oil pump 11 is quickly started to ensure oil pressure required for controlling gear shift and engagement of the clutch. COPYRIGHT: (C)2006,JPO&NCIPI
