A start control apparatus includes a position sensor (14), a basic start determination processor, and a sensor output determination processor (53), and a start permission continuation processor (55). <??>When a power line for supplying electrical current to the starter motor is provided near the position sensor, a magnetic field is generated by the electrical current flowing by starting the starter motor. The magnetic field may affect the Hall IC, and couse errors in the sensor output of the Hall IC, and decrease the performance of the Hall IC. <??>As a result, even if the shift lever is actually in a position for selecting the engine start range, it may be determined erroneously that the engine start range is not selected due to the errors generated in the sensor output of the Hall IC. In this case, the start of the starter motor is prohibited unintentionally. To avoid this inconvenience, when the start permission signal is generated, the motor is started, and electrical current is supplied to the motor, it is determined whether distinctive variation characteristics are detected in the sensor output. When the distinctive characteristics are detected, permission for the start of the motor is continued. Therefore, the start of the motor is not prohibited when the shift lever is actually in the position for selecting the engine start range, and the engine is started reliably. Thus, the driver does not feel a sence of discomfort. <??>Further, when a power line is provided near the position sensor, it is not necessary to provide a shield or the like for interrupting the magnetic field for protection. <IMAGE> |
