ENGINE STARTER DEVICE FOR VEHICLES

To provide an engine starter device for vehicles that prevents kickback on the basis of crankshaft speed in the vicinity of the compression top dead center of an engine. A motor stage determination unit (801) of a kickback prevention unit (80B) determines the angular range of an ACG starter motor (48) as a motor stage (MSTAGE) on the basis of the direction of the current flowing through each phase of the ACG starter motor (48). An instantaneous NE measurement unit (802) measures the instantaneous NE of a crank shaft (40) for each stage. For example, if the motor stage is switched at a 10-degree cycle, the instantaneous NE within said 10 degrees is measured. An ignition control unit (803) delays the ignition timing of the engine when the instantaneous NE at a crank angle corresponding to the vicinity of the top dead center of the engine is equal to or less than a reference NE (NEref). 提供车辆用发动机起动装置，其基于发动机的压缩上止点附近处的曲柄轴速度来防止反冲。反冲防止部(80B)的电机状态判断部(801)基于在ACG起动电机(48)的各相流动的电流的流向而将该ACG起动电机(48)的角度范围作为电机阶段(MSTAGE)来判断。瞬时
