DEVICE AND METHOD FOR CONTROLLING ISG LOGIC

摘要

PURPOSE: An apparatus and a method for controlling ISG logic are provided to stably start ISG vehicles by controlling engine RPM and the fluid pressure of a brake after an idle stop. CONSTITUTION: An apparatus for controlling ISG logic comprises a transmission unit, a driving unit, and a braking unit. The transmission unit displays the current state of a gear level of a vehicle, and controls the fluid pressure of a transmission during the re-staring or idle stop. If a brake pedal is turned on while the gear level is in a driving state, the driving unit performs the idle stop. If the brake pedal is turned off while the gear level is in the driving state, the driving unit re-starts an engine. The braking unit controls the behavior of the vehicle by controlling the fluid pressure of the brake. The transmission unit controls the auxiliary oil pump of the transmission in order to maintain the fluid pressure of the transmission.
