Abstract

The invention discloses a ripple wave anti-pinching control method for an automobile window. The ripple wave anti-pinching control method for the automobile window includes the following steps that inthe running process that automobile window glass ascends and descends, under the condition that the glass does not ascend to the top and does not descend to the bottom, after the automobile window isoperated N times in an inching manner or automatically, when a user performs operation for descending, the automobile window glass is forced to descend to the bottom so that pulse calibration of thetravel of the automobile window can be performed; when the automobile window glass ascends to the top, travel calibration is performed, and the pulse travel is set 0; when the automobile window glassdescends to the bottom, travel calibration is performed, and the automobile window pulse travel stored in an EEPROM is taken out and is assigned to a current automobile window position counter; duringignition starting of an engine, the window ascending and descending forbidding function is stopped, except the anti-pinching operation happens; after the anti-pinching operation happens 3 times, theanti-pinching function is cancelled in 5 s, and the anti-pinching function is automatically restored after 5 s; when the automobile window glass ascends or descends N times, the function of soft stopis cancelled one time, and the automobile window travel calibration is performed; and the automobile window travel is ceaselessly calibrated, and the anti-pinching safety and reliability of the automobile window are greatly improved.

Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to an automobile window ripple anti-pinch control method. Background technique

[0002] Ripple anti-pinch is used more and more in the existing technology, but because the ripple anti-pinch inherently has the defect of losing pulses when the window starts and stops, so that real-time compensation for pulses is required, but because the pulses are integers, the mathematical construction Modulo compensation is often a multiplication and division operation. Due to the operation, the decimal point will be lost when the data type is converted, which will cause the cumulative error of the pulse stroke. Contents of the invention

[0003] The object of the present invention is to provide an automobile window ripple anti-pinch control method, which continuously calibrates the stroke of the window and greatly improves the safety and reliability of the anti-pinch of the window.
