Abstract:
To provide an automatic closure control device that can reduce the number of internal switches more than before.SOLUTION: An automatic closure control device, which controls a closure mechanism driven by a motor to bring a vehicle door into a fully closed state, detects a state of an internal switch that detects an engagement between a latch of the closure mechanism and the vehicle door, and a drive current that is supplied to the motor when a PWM (Pulse Width Modulation) signal is supplied to the motor as a drive signal, and estimates an operation state of the closure mechanism on the basis of the drive current and the state of the internal switch, thereby bringing the vehicle door into the fully closed state.SELECTED DRAWING: Figure 1
