Abstract

A control method of an idle stop and go system is provided. The method includes determining whether a stop condition of an engine operating in an idle state is satisfied and determining whether a pressure increase value of a brake oil formed during a predetermined time period is greater than a predetermined value when the stop condition of the engine is satisfied. A valve connected to a hydraulicline to which the brake oil pressure is transmitted is then temporarily closed and then reopened when the pressure increase value is greater than the predetermined value. The engine is stopped after the valve is temporarily closed and reopened.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2017-0147520 filed on November 7, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a control method of an idling stop and start system, which reduces exhaust gas and fuel consumption by stopping the engine when a stop condition is satisfied while the engine is rotating in an idling state, and in the stopped state of the engine, When the release condition is met, restart the engine. Background technique [0004] Normally, even when the vehicle is stopped, the engine continues to run, so fuel continues to be consumed, which further pollutes the air environment. Accordingly, research has been conducted on idle stop and go (ISG) systems in order to reduce fuel consumption of vehicles and protect the environment. When the vehicle is stopped and certain conditions are ...
