Abstract

The invention relates to a touch recognition method and device for a touch key, a vehicle, equipment and a medium. The method comprises the steps of: obtaining a sampling output signal based on an output electric signal of a capacitive touch key; calculating the cumulative increment of the rising time period in the sampling output signal; acquiring the duration time value of the accumulated increment belonging to a preset first threshold range; when the duration value is greater than or equal to a preset second threshold value, judging that a touch signal exists; determining the maximum valueof the accumulated increment as an attenuation recognition threshold value; and using the processor for receiving the sampled output signal, calculating the accumulated reduction amount of a descending time period in the sampled output signal, and confirming that the touch is ended when the accumulated reduction amount belongs to a third threshold range determined based on the attenuation recognition threshold, wherein the maximum value of the third threshold range is smaller than the attenuation recognition threshold. According to the invention, by recognizing the rising trend segment of thepulse signal caused by finger touch, the touch signal applied to the capacitive touch key by the user can be effectively recognized, and omission recognition, false recognition and / or false triggeringof the touch signal are / is avoided.

Description

technical field [0001] The present application belongs to the technical field of touch keys, and in particular relates to a touch recognition method, device, vehicle, equipment and medium of touch keys. Background technique [0002] Due to its long service life, high safety and beautiful appearance, capacitive touch buttons are gradually replacing traditional mechanical buttons and are widely used in products that require buttons such as mobile phones, home appliances, smart homes, and cars. [0003] However, the traditional capacitive touch keys are prone to false triggers during use, or the technical problem of missing touch signal recognition, which brings troubles to users. Contents of the invention [0004] Based on this, it is necessary to address the problems in the above-mentioned background technology and provide a touch recognition method, device, vehicle, equipment and method that can effectively recognize the touch signal applied by the user to the capacitive t...
