Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The window ripple multi-channel anti-pinch control module provided by the embodiment of the present invention includes: five current detection units, five isolation, filtering, amplification, shaping units, five drive output units, switch acquisition unit, communication unit and central control unit unit, among which, five current detection units are used to detect the current change of the window and sunroof motors when they are working, so as to determine whether obstacles or resistance are encountered in the anti-pinch area. When an obstacle is encountered, the motor stops rising and boun...

Abstract

The invention discloses a car window ripple wave multiway anti-pinching control module and method. The control method includes the following steps that S1, when a motor moves, pulse signals formed by ripple waves are acquired in real time; S2, after the acquired signals are processed, the position of a car window and the position of a skylight are determined by distinguishing whether obstacles or resistance exists in an anti-pinching region or not; S3, when the obstacles exist in the anti-pinching region, the car window or the skylight is controlled to rebound to the safe distance; S4, when the car window or the skylight is completely opened or completely closed, the motor is controlled to stop moving, stalling of the motor is avoided, and the motor is protected. By means of a ripple wave mode, a four-door anti-pinching function can be achieved only with one module, and cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to a control module and method for multi-channel anti-trapping of vehicle window ripple. Background technique [0002] In recent years, automobile products have gradually become popular in our country and entered the field of mass consumption. But the risks that come with it are also emerging. For example, there are frequent accidents in which passengers are accidentally pinched by electric windows in cars, and the injuries to children are especially serious. The door and window control module with automatic anti-pinch function has gradually become a trend, and the demand for all four doors with anti-pinch function is gradually increasing. The four-door anti-pinch door and window control system in the Hall mode requires four door control DCU modules, which is costly. Contents of the invention [0003] Aiming at the defects of the prior art, the purpose of the present i...
