Method of and apparatus for opening/closing control of motor-driven opening/closing member of vehicle

摘要

An opening/closing control apparatus detects an overload placed on a movable member of a vehicle such as a sunroof and a power window while it is sliding. Further, it prevents overload detecting operation (reversing motion) from being made by a cause other than an overload. A control processor circuit compares a driving current value of a motor detected at predetermined intervals with a preset current value and corrects an overload threshold value to a threshold value of higher value when the driving current value detected when a first predetermined time period has passed after the start of the motor does not exceed the preset current value. Thereafter, the control processor circuit determines that an overload has occurred when a change in the driving current value has exceeded the overload threshold value.
