Description
Technical field
This utility model relates to body of a motor car electronic applications, relates more specifically to a kind of anti-pinch vehicle dormer window controller based on detection motor load electric current.
Background technology
The skylight that anti-pinch vehicle dormer window controller is mainly used on automobile controls, and in the closing process of skylight, if running into obstacle, when causing resistance (the most anti-grip force) to reach certain value, skylight does not turns off, but retreats, and skylight is opened to maximum rating stopping.
Current anti-pinch vehicle dormer window controller is broadly divided into measurement skylight motor load electric current and catches two kinds of methods of Anti-pinch motor Hall element pulse to identify whether skylight clips to foreign body or human body, the method catching Hall element signal, owing to anti-grip force is accurate, commonly used by some luxury cars, but its fancy price, also makes some low and middle-grade cars configuration skylight to realize.Using the method measuring load current, owing to using common DC motor, its motor cost is substantially reduced, but its load current fluctuations is less, causes anti-grip force to be forbidden, once in a while it also occur that skylight clips to the people that child's neck causes dies accident.Some anti-pinch louver controller uses Anti-pinch motor, but owing to control algolithm falls behind, again results in anti-grip force and control inaccurate, thus cause accidents such as missing folder.
Utility model content
