Abstract:
1. A start control device for a vehicle comprising: an operation detection device that detects a signal from an engine starting switch for starting a first engine mounted in a vehicle; a rotational speed detection device that detects engine rotational speed of the first engine; a coolant temperature detection device that detects coolant temperature in the first engine; a storage device that stores a first coolant temperature map in which first determination rotational speeds for use in determining whether or not the first engine has achieved complete combustion are determined for several coolant temperatures in the first engine, and a second coolant temperature map in which second determination rotational speeds for use in determining whether or not a second engine has achieved complete combustion are determined for several different coolant temperatures in the second engine; a complete combustion determination device that determines that the first engine is in a complete combustion state when the rotational speed of the first engine reaches one of the first determination rotational speeds that is determined for the coolant temperature detected at the start of the first engine in the first coolant temperature map; a starter motor control device that controls a starter motor to cause the starter motor to crank the first engine from the time when the operation detection device detects the signal until the complete combustion determination device determines that the first engine is in a complete combustion state; and an information acquisition device that acquires first engine information on the first engine, wherein the storage device has stored the first coolant temperature map and the second coolant temperature map associated with the first engine information and second engine information, respectively, and wherein, when the information acquisition device acquires the first engine information, the complete combustion determination device selects the first coolant temperature map associated with the first engine information and determines that the first engine is in the complete combustion state based on the first coolant temperature map.
