2. The window anti-pinch technology is realized by "touch" and "vision". The so-called "touch" means that when the electric window mechanism senses that there is a foreign body on the glass, it will automatically stop the glass from rising. Relying on "vision" is an advanced control system, actually an optical control system, which monitors whether there are foreign objects in the moving range of the electric window, so as to control the glass movement and prevent foreign objects from touching the glass.
3. Many window anti-pinch devices judge the position of the glass through the Hall sensor. If a foreign object prevents the glass from rising during the glass rising, the electric window will immediately stop rising and immediately descend to the bottom to realize the anti-pinch function.
4. The so-called anti-pinch electric window is to install a set of current sensors, and the Hall sensor always detects the speed of the motor. When the electric window rises, once the motor speed slows down, when the Hall sensor detects that the speed changes, it will report information to the ECU, and the ECU will send instructions to the relay, and the circuit will reverse the current to stop the motor from rotating or reversing (descending), so that the window will stop moving or descending, so it has certain anti-pinch function.
