PURPOSE:To enhance the safety by studying the load of a motor when a motor- driven window is opened or shut, compairing the motor load, and reducing the load upon judging as pinching-in in case the motor load is greater. CONSTITUTION:When an opening covering member M1 is moved being driven by a driving means M2, the value based on the load of the driving means M2 sensed by a load sensing means M3 is studied as a comparative value by a comparative value studying means M4. When the driving means M2 is going to start, the comparative value is studied on the basis of the comparative value at the time of being stopped. When thereafter the covering member M1 is driven by the driving means M2 to make movement, the load of the driving member M2 sensed by the load sensing means M3 is compared with the studied comparative value by a comparing means M5. If the judgement is that the sensed load is greater than the studied comparative value, the load of the driving means M2 is reduced forcedly by a drive stop means M6. This permits precise sensing of the pinching-in, etc., irrespective of possible secular change. |
