Problems solved by technology

But at the same time, due to the sensitivity characteristics of the touch panel during driving, the user will inevitably encounter certain areas during driving, which will cause false triggering of the keys.
As a result, the impact on driving comfort and safety cannot be underestimated.
[0003] If a force-sensing solution is used, the button can only be triggered after the user reaches a certain pressure on the touch button, which can reduce the risk of false triggering, but at the same time will cause an excessive cost burden

Embodiment 1

[0034] Such as figure 1 , the installation area of ​​the automotive interior touch panel is around the central control shifter, among which A1, A2, A3, A4, B1 and B2 are buttons visible on the shape of the touch panel. During driving, due to the touch panel Sensitivity characteristics, the user will inevitably encounter certain areas, such as B1, during driving, which will cause false triggering of buttons.

[0035] According to the user's human-computer interaction habits, when manipulating, the palm will be placed on the C area, and the C area will be kept in contact with the C area for a long time during the operation of other buttons. The invisible sensing area of ​​the C area is used as the detection area. Area.

[0036] A method for preventing false touches of a touch panel in this embodiment, such as figure 2 , including the following steps:

[0037] S1. Set the detection area C to identify the touch event;

[0038] S2. Determine whether the touch event is valid, a...

Embodiment 2

[0051] A method for preventing false touch of a touch panel in Embodiment 1, such as figure 2 , the difference is that when the detection zone is not triggered, step S4 is executed,

[0052] Step S4 includes the following sub-steps:

[0053] S41. Collect the trigger touch area and trigger touch time in the touch panel area;

[0054] S42. Perform analog-to-digital conversion on the trigger touch area to obtain a second detection value positively correlated with the trigger touch area;

[0055] S43. If the second detection value is greater than 50% or the trigger touch time is greater than 30 ms, determine that the touch event is legal; otherwise, the touch event is illegal, and determine that it is a false trigger.

[0056] Wherein, the second detection value is a percentage of the trigger touch area or the detected touch area to the total touch area in the area.

[0057] Through the method in the present invention, by collecting the trigger touch area and trigger touch tim...

Abstract

The invention discloses a method for preventing mistaken touch of a touch control panel. The method comprises the steps that S1, a detection area is arranged to identify touch control events; S2, whether the touch control events are valid or not is determined, and if yes, whether the detection area is triggered or not is judged; S3, if yes, the triggered events are judged to be legal, otherwise the step S4 is executed; S4, according to the triggered touch area and the triggered touch time of the triggered events, whether the touch control events are legal or not is judged, wherein the detection area is arranged on the touch control panel according to the man-machine interaction habit of a user and is kept in a contact state for a long time during operation. The method can effectively lower the mistaken triggering probability of a touch key, effectively lower the interference of the surrounding environment to the touch control panel and reduce mistaken triggering.

Description

technical field [0001] The present invention relates to the field of false touch prevention, and more particularly, to a method for preventing false touch of a touch panel. Background technique [0002] At present, the development trend of automotive interior control panels has gradually evolved from traditional button panels to touch panels. Touch panels have the characteristics of long service life and high reliability. At the same time, they can also be very well adapted to different interior styling requirements. . In terms of lighting effects, the touch panel lighting can be combined with sliding and scrolling gestures based on sliders and pulleys, which has excellent human-computer interaction effects. At the same time, because it is a non-mechanical contact switch, there are no mechanical moving parts, and the panel can be made into a sealed type, which can also effectively achieve the effects of waterproof, dustproof, oil-proof and anti-static interference. But at ...
