Starting control method for idle stop-start vehicle

Abstract

The present invention relates to a starting control method for an idle stop-start vehicle, wherein the idle stop-start vehicle comprises a battery system, a starter generator control system, an engine fuel injection control system, an engine with a crankshaft and a key switch. The starter generator control system includes a starter generator controller and a starter generator device. The starter generator controller is electrically connected to the battery system, the starter generator device and the key switch, and stores a first angle information of the crankshaft before the key switch is turned off. The engine fuel injection control system is communicatively connected to the starter generator controller. The starter generator device is coaxially arranged with the crankshaft. The engine fuel injection control system is electrically connected to the battery system and the engine, respectively. Thus, through the starting control method of the idle stop-start vehicle of the present invention, the engine fuel injection control system can be effectively improved to accurately control the injection at the correct angle that the crankshaft rotates while the engine is to be started, so that the engine can be started faster and the time for the starter generator control system to drive the engine can be shortened.
