Abstract: The motor control device is an electric motor control device including a control unit (control circuit unit) configured to output a forward-rotation command or a reverse-rotation command to the electric motor. The control unit includes a position detector (door opening/closing information generation circuit) configured to detect a rotation direction of the electric motor when a detection signal is input from a rotation sensor (Hall integrated circuit (IC)), which detects the rotation of the electric motor, while no current is supplied to the electric motor. The control unit includes an electric current supply device (pulse width modulation (PWM) command generation circuit) configured to supply an electric current by which the electric motor is rotated in an opposite direction to the detected rotation direction by increasing an electric current supply duty ratio every time the detection signal is switched.

Abstract: When a main switch (82) is in an on-state, a controller (80) allows an electric motor (41) to drive a sliding door to open and close an opening, and when the main switch (82) is in an off-state and a half latch switch (66) is in an on-state, the controller (80) performs a braking control to allow the electric motor (41) to generate a braking force. When the main switch (82) is in the on-state, the sliding door can be opened and closed automatically. When the main switch (82) is in the off-state and the sliding door is closed manually, the improperly-closed state detecting switch is switched on before a full-latch state, the controller performs a braking control of the driving source. In this manner, damage to components caused by the inertial force of the driving source which results from an abrupt stop of the opening and closing unit can be certainly prevented without enhancing the rigidity of a casing, etc.
