Abstract:
1. An engine start controller, comprising: a battery; a starter motor driven by the battery to start an engine; an activation switch that outputs a START command for starting the engine; an engine start control unit directly connected to the activation switch and outputs an OPERATE command when the START command is received from the activation switch; a bypass circuit directly connected to the activation switch, such that both the engine start control unit and the bypass circuit receive the START command simultaneously; an activation circuit connected to the engine start control unit and the bypass circuit, and connects the starter motor to the battery to activate the starter motor when at least one of the OPERATE command output from the engine start control unit and the START command via the bypass circuit is received; and revolution-detecting unit that detects a revolution of the engine, wherein, the engine start control unit outputs the OPERATE command when the engine start control unit receives the START command from the activation switch, and also determines, based on the detected revolution of the engine, that the engine is rotating at a speed less than a predetermined value due to the START command received via the bypass circuit.
