RESTART RESPONSIBLE METHOD OF IDLE STOP AND GO FUNCTION

摘要

PURPOSE: An ISG(Idle Stop & Go) restarting reaction method is provided to improve restarting reactivity using a gradient change of brake oil pressure immediately reacting to the change of pushed degree of a brake pedal and dropping after an idle stop. CONSTITUTION: An ISG restarting reaction method determines a change timing of an Idle-Go using a gradient change of brake oil pressure immediately reacting to the change of pushed degree of a brake pedal and dropping after an idle stop. A determining method is as follows. Conditions for an Idle-Stop are satisfied so that the brake oil pressure is monitored while the engine is turned off. A maximum value(A=max) of the brake oil pressure is detected and memorized, and the brake oil reduced in comparison to the maximum value is detected(S50). [Reference numerals] (AA) Start; (S10) Idle-stop conditions are satisfied?; (S20) Stopping an engine; (S30) Detecting the current brake oil pressure; (S40) A=max(brake oil pressure); (S60) Restarting the engine
