Problems solved by technology
Among them, the window anti-trap control is an important part of the car window control. The existing window anti-trap solutions usually require manual intervention to set, the operation is complicated, and it takes a long time. Professional and technical personnel are required to set and adjust the system. Re-calibration is required after the environment changes, the error is large, and the probability of failure is high. Once it fails, it will easily cause serious personal injury and property loss, and negatively affect the vehicle brand image.

Embodiment Construction
[0052] The key detection algorithm flow is as follows: figure 1 shown, including steps:
[0053] Step 1. Perform parameter initialization, set the window up button counter, window down button counter, set the window up button anti-mistouch flag value, window down button anti-mistouch flag value, window up button timeout action value , The overtime action value of the window down button, set the trigger value of automatic up and down, the value of the stop sign for the automatic up switch of the window, and the value of the stop sign for the automatic down switch of the window.
[0054] Step 2. Taking the rising process as an example, the count value of the counter is accumulated after the lift button or the remote lift command is triggered. If the count value of the window lift button counter is less than the set window lift button anti-false touch flag value, it is considered that a false touch action has occurred and the action will not be executed. , otherwise go to step 3...

The invention discloses a high-reliability vehicle window control method; and designed algorithms comprise a key detecting algorithm, a motor fault detecting algorithm and a vehicle window anti-pinching algorithm. A counting value of a counter set in programs in the algorithms is used as a reference value to judge if the key operation is normal; the counting value of the counter set in the programs and a motor returned current sampling value are used as main reference values to judge if a motor is broken down; and the counting value of the counter set in the programs and the motor returned current sampling value are used as the main reference values to judge if a vehicle window meets an obstacle. The vehicle window control is realized through software algorithms without adding hardware orwiring harness, so that the cost and the assembly time are saved. The anti-pinching algorithm performs self-learning calibration in the vehicle window acting process to guarantee that the anti-pinching control follows up the equipment state, so that the policy deployment control time is reduced, and the production efficiency is improved. The method improves the vehicle window control intelligenceand the equipment reliability.
Description
technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a method for controlling windows with high reliability Background technique [0002] With the increasing development of the automobile industry, from the national automobile industry strategic planning to individual users, more and higher demands have been put forward for the intelligentization of automobiles, while traditional automobile electronics are limited to simple control of mechanical parts of automobiles. The popularization of new technologies such as technology and network communication technology in the field of automotive electronics has made automobiles more and more intelligent, and more and more functions that were only available in high-end cars before have become standard equipment for modern cars. As an important part of a car, windows are an important part of the car, and the intelligent control of windows has become a standard feature of modern cars. ...
