Obstruction sensor

What is an obstruction sensor and where it is to find everywhere? It is the interconnection of the activity of an electric motor to the results of its work. Not so easy. For how can it discover whether the larger effort eg for closing a glass pane based on stiff window guides or real obstacles?

The methods, with those an electric motor or its electronics remarks possible obstacles, you can read here. We deal now with their effects in practice, state of the art 2015. To do this we first need to extend significantly the spectrum, because now not only windows are electrically opened and closed primarily.

There are so-called closing aids, if e.g. a rear door when getting out was ajar only. So as a driver you have to get out no longer and close the door. Is it a sliding door, so it opens and closes more often electrically. Of course, this also applies to the sunroof and the roof of convertibles. The preliminary endpoint is reached with the automatic tailgate, for its control often gestures are enough.

Brave New World, but showing cracks when it comes to the pinch protection. The seems particularly difficult just before the final closure of the mostly heavy flaps. Children's hands can suffer serious injuries here. So at this point the advice, please once this accident protection to try on your own car at all places be worth considering, possibly even before buying a car at the dealer. The pinch protection is namely only prescribed when the function continues to run automatically by touching the relevant button.

Because one thing is not at all certain, namely that it works everywhere, as with the driver's door. Some manufacturers already start to skimp on the passenger door. The more cost-effective and smaller the car, the more likely the pinch protection is entirely absent. Perhaps it is here believed that the motors are too weak for serious injuries. But you know, even a weak can be strong with the appropriate transmission

Whether now makes sense or not, even the normally functioning pinch protection is not guaranteed in any case. Knows your child that this only works if one taps only briefly the button for 'go up'. If you hold it tight, the electric motor prevails whatever the cost. In any case, you should this play through once with your little child with an artificial finger.

In the absence of pinch protection, the force, by which an injury is possible, conforms to the component to be moved. The forcibly closing window perhaps might not lead to a bone injury, the closing of a door or even tailgate but already. And indeed, there are manufacturers that are able even these considerable forces to catch so that nothing can happen here. 11/15
