Claims (4)

[Claims] 1. A starter control device for a vehicle-mounted internal combustion engine, comprising: a starter that starts and drives an internal-combustion engine mounted on a vehicle; and a control unit that controls the starter. A detection unit that detects an intention display operation related to a starter operation by a driver other than the operation, the control unit based on the detection by the detection unit,
A starter control device for a vehicle-mounted internal combustion engine, which controls the starter of the vehicle's internal combustion engine to be driven. 2. The starter control device for a vehicle-mounted internal combustion engine according to claim 1, further comprising: when a driver identification code is input from a driver, the input identification code and an identification registered in advance. A starter control device for a vehicle-mounted internal combustion engine, comprising: a normal user confirming means for permitting drive control of a starter of the control means when the two identification codes match with each other by comparing the codes. 3. The starter control device for a vehicle-mounted internal combustion engine according to claim 1, further comprising: a seating detecting unit configured to detect whether a driver is sitting in a driver's seat; and a seating detecting unit. A starter control device for a vehicle-mounted internal combustion engine, comprising: seat confirmation means for permitting drive control of a starter by the control means when a seat is detected. 4. The starter control device for a vehicle-mounted internal combustion engine according to claim 1, wherein:
Further, a failure detection means for detecting whether there is an obstacle to the start of the vehicle, and a failure for permitting starter drive control of the control means when the failure detection means detects no failure. A starter control device for a vehicle-mounted internal combustion engine, comprising: a presence / absence check unit.
