Abstract:
1. An abnormality detection apparatus for a starter control system of a vehicle, which includes a pinion control actuator, a motor control switch part, a first drive part and a second drive part, the pinion control actuator, when energized, moving a pinion gear of a starter for starting an engine of a vehicle from an initial position at which the pinion gear is disengaged with a ring gear of the engine to an engagement position at which the pinion gear is engaged with the ring gear, the motor control switch part provided in a current supply path to a motor of the starter which rotates the pinion gear, and operable to turn on independently of energization of the pinion control actuator and energize the motor by conducting the current supply path when turned on, the first drive part for performing a first drive operation, which energizes the pinion control actuator to move the pinion gear from the initial position to the engagement position at a start time of starting the engine, the second drive part for performing a second drive operation, which turns on the motor control switch part to energize the motor to start cranking of the engine after an elapse of a predetermined delay time from a start of the first operation of the first drive part, the abnormality detection apparatus comprising: a start time abnormality detection part for checking whether an actual delay time is a normal value, the actual delay time being an actual period from a start of the first drive operation by the first drive part to a start of the second drive operation by the second drive part at the time of starting the engine.
