Title:
CONTROL DEVICE FOR IDLE STOP AND RESTART FOR VEHICLE
Document Type and Number:
Japanese Patent JP3589143
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To avoid the risk when the time required for restart is long in a vehicle in which the idle of an engine is stopped in a temporary parking and driven by a motor in restart operation and then restarted, and to ensure a quick starting performance in a slope.
SOLUTION: In the release after idle stop, the elapsed time is measured while driving the engine by the motor (S1-S3). In a place except a slope, an idle stop prohibition flag FPH is set to 1 when the engine speed after the lapse of a prescribed time is less than a lower limit value to prohibit the following idle stop (S4-S7). The engine is then restarted after the intake negative pressure is developed (S9→S10), and the engine is immediately restarted in the slope (S4→S10).
