Abstract:
Disclosed herein is a sunroof control apparatus for preventing malfunctions. The sunroof control apparatus includes a sunroof motor which opens and closes a sunroof and a control portion which outputs a first control signal which drives the sunroof motor in a direction of opening the sunroof and a second control signal which drives the sunroof motor in a direction of closing the sunroof. Here, the control portion estimates angular velocity, torque, and a torque change rate according to a current voltage of the sunroof motor based on an estimator designed in advance. Also, when the estimated torque change rate is a preset threshold or more, the control portion determined that an object is caught in the sunroof while the sunroof is being closed and outputs the first control signal.
