What is anti-pinch power window technology?
Anti-Pinch Power Window: Anti-pinch technology is a safety system which modern vehicles employ in the power windows. The power window is the window which uses an electric motor to operate. As the name suggests, this technology prevents the winding up of the power window.

The power window is the window that uses an electric motor to operate. As the name suggests, this technology prevents the accidental winding up of the power window. If the system senses any obstacle in the path of the glass, it prevents the window glass from moving further up.
What is the maximum force a power window can exert?
The maximum force a power window is allowed to exert on any object is 100N. Compliance with this limit must be monitored and enforced in a range of 4mm to 100mm from the top window frame, which is successfully meet by prototype designed.
How does the speed of the power window system work?
The speed is selected based on the window gap and is reduced as the window gap approaches a pinch region such that the pinch-force is limited to a safe value. A vehicle power-window system ( 400 ) comprises a window assembly ( 410 ), a battery ( 420 ), an electric motor ( 430 ), a mechanical assembly ( 440 ), and a control circuit ( 450 ).

Q: How Does the Anti-Pinch Feature Work on My Power Windows? - YourMechanic
Basically, anti-pinch works by measuring the amount of electrical current the motor uses that drives the glass up and down. Like practically everything on a modern car, the windows are controlled by an electronic control unit (ECU).When you operate the switch for the window to go up or down, you’re actually just sending a signal to the ECU that you want the window to go up or down, so the ...

A power window anti-pinch sensor, characterized in that, at least two capacitors and sensor detecting circuits are provided on the surface of the top edge of the window glass (13); the most top capacitor is the main detecting capacitor C1, and the lower capacitor is the auxiliary detecting capacitor C2. The main detecting capacitor C1 and the auxiliary detecting capacitor C2 detect whether ...
What is anti pinch window?
Hence In the case of window equipped with anti-pinch technology, the electric motor is fitted with a sensor which can sense the resistive force acting against the motion of the glass. As soon as the motor detects the obstacle, the winding action stops immediately and it starts operating in reverse direction. As a result, the window comes down; avoiding any injury to the occupant.

How does battery voltage affect window speed?
For example, in systems that close the window at a uniform speed (which must be relatively low in order to satisfy anti-pinch requirements), a reduction in battery voltage has the undesirable effect of further decreasing the already low speed at which the window closes. Thus, there is also a need for an approach that at least partially compensates for variations in battery voltage so that the amount of time that it takes to close the window is less negatively impacted.
What is H02H7/08?

Why is the shaft of the electric motor driving the window rotating too fast to be stopped in time?
In some existing power window systems, the shaft of the electric motor driving the window generally rotates too fast to be stopped in time to avoid exceeding a 100 newton pinch force. This is a consequence of the fact that conventional power window motors have considerable inertia and thus do not slow down instantaneously . Therefore, to avoid exceeding the maximum allowable pinch force, it is necessary that the window speed be limited while the window is being raised through the pinch region.
What is power window?
Power windows are standard equipment in many vehicles manufactured at the present time. An important problem in power window systems relates to pinch force, which is defined as the force that is exerted upon an obstruction (e.g., a person's head) that is introduced between the window glass and the window frame while the window is closing. One accepted specification is that, while the window gap (i.e., the distance between an upper edge of the window glass and a corresponding top portion of the window frame) is between 4 millimeters (mm) and 30 mm (i.e., the pinch region), the pinch force must not exceed 100 newtons.

What is step 104?
Step 104includes four sub-steps that are described as follows: (a) when the window gap, y, is greater than a first value (e .g., 60 millimeters), V is set at a first voltage, V1, as described by 106,108; (b) when y is less than the first value but greater than a second value (e.g., when 60 mm≧y>30 mm), V is set at a second voltage, V2, that is monotonically adjusted as y is reduced, as described by 110,112; (c) when y is less than the second value but greater than a third value (e.g., when 30 mm≧y>4 mm), V is set at a third voltage, V3, as described by 114,116; and (d) when y is less than the third value but greater than zero (e.g., when 4 mm≧y>0), V is set at a fourth voltage, V4, as described by 118,120. When y reaches zero, the window is closed and V is set equal to zero.
