    • Purpose: To provide an engine start control device that can secure electronic reliability without increasing the number of parts for detecting abnormalities Solution means: This device is equipped with a switch 127 that turns on and off the supply of power to a starter motor of an engine, a first starter switching element 131 and a second starter switching element 152 connected in series in a power supply circuit for the above-mentioned starter motor, a first control means 126 that sequentially turns on/off the first starter switching element and the second starter switching element based on operation of the switch 127, a voltage detection means 144 that detects the voltage at a connection point P between the first starter switching element and the second starter switching element, and a second control means 126 that detects abnormalities of the first starter switching element and the second starter switching element from the voltage at the connection point detected by the voltage detection means.
    • 目的:提供可以确保电子可靠性而不增加用于检测异常的部件数量的发动机起动控制装置解决方案:该装置配备有开关127,其向发动机的起动电动机供电, ,在上述起动电动机的电源电路中串联连接的第一起动开关元件131和第二起动开关元件152,顺序地接通/断开第一起动开关元件和第二起动器的第一控制单元126 基于开关127的操作的开关元件,检测第一起动开关元件与第二起动开关元件之间的连接点P的电压的电压检测单元144以及检测第一起动器的异常的第二控制单元126 开关元件和第二起动器开关元件从由电压检测到的连接点处的电压 表示手段。
