Method for controlling idle stop-and-go system
First Claim
1. A method for controlling an idle stop-and-go system based on one or more engine control modes including a starting mode wherein an engine control unit (ECU) starts an engine based on an engine stop release signal received from a starter/generator control unit (SCU), a normal mode for normally operating the engine, and an after-run mode wherein the ECU stops the engine based on an engine stop signal received from the SCU, the method comprising:
- determining whether a present engine control mode is the normal mode;
determining whether an engine stop signal is received from the SCU;
changing the engine control mode to the after-run mode in the case that the present engine control mode is the normal mode and an engine stop signal is received from the SCU; and
blocking illumination of an engine warning lamp.

Abstract
The method for controlling an idle stop-and-go system is based on one or more engine control modes, including a starting mode wherein an engine control unit (ECU) starts an engine by an engine stop release signal received from a starter/generator control unit (SCU), a normal mode for normally operating the engine, and an after-run mode wherein the ECU stops the engine based on an engine stop signal received from the SCU. Initially, it is determined whether a present engine control mode is the normal mode. Thereafter, it is determined whether an engine stop signal is received from the SCU. The engine control mode is then changed to the after-run mode whern the present engine control mode is the normal mode and an engine stop signal is received from the SCU. Finally, the engine warning lamp is blocked from illuminating.
