Patent number: 8934211Abstract: A solenoid control device executes feedback control such that a drive current for a solenoid follows a target current, by driving, through PWM, a MOSFET provided on a power supply line to the solenoid. An overcurrent detection circuit that outputs an overcurrent detection signal when the drive current for the solenoid reaches an overcurrent determination current value is provided, and it is determined whether an overcurrent is generated. Whether a short-circuit occurs between both terminals of the solenoid is determined by monitoring whether the overcurrent detection circuit is repeating an output of the overcurrent detection signal and a stop of the output of the overcurrent detection signal.Type: GrantFiled: February 26, 2013Date of Patent: January 13, 2015Assignee: JTEKT CorporationInventors: Atsushi Takeshita, Hisaaki Wakao, Kiyoshige Kato, Kazuhiro Murakami
