Abstract

A method of controlling an electromagnetic relay includes supplying a first voltage to an exciting coil to bring a movable terminal into contact with a fixing terminal; causing a coupling state determination unit to determine that a coupling failure is detected in a case where the movable terminal is not brought into contact with the fixing terminal and the electromagnetic relay is not turned on despite the supplying the first voltage to the exciting coil; and supplying a second voltage higher than the first voltage from a booster circuit to the exciting coil in a case where the coupling state determination unit determines that the coupling failure is detected. The second voltage is generated by boosting the first voltage by the booster circuit.
