  • Startup control device, lock determination method, and method for controlling starter motor
    Patent number: 10202922
    Abstract: A startup control device controls a starter motor. The startup control device includes lock determination circuitry and motor control circuitry. The lock determination circuitry estimates a current value supplied to the starter motor based on a temperature of a battery, a remaining electricity amount in the battery, and an output voltage of the battery when the battery supplies electricity to the starter motor, determines a threshold period of time according to the current value estimated, and determines that an internal combustion engine does not start if a rotational speed of the internal combustion engine does not exceed a referenced speed within the threshold period of time after starting supplying electricity to the starter motor. The motor control circuitry stops supplying electricity to the starter motor when the lock determination circuitry determines that the internal combustion engine does not start after starting supplying electricity to the starter motor.
