Abstract

The invention provides a touch key control method and control system, and the method comprises the following steps: a touch key generating a corresponding capacitance value C according to the touch action of a user; when the capacitance value C rises from an initial value C0 to a set upper limit threshold value C1, the vibration unit driving the touch key to generate a vibration sense; when the capacitance value C is decreased from the upper limit threshold value C1 to the lower limit threshold value C2, the vibration unit driving the touch key to generate vibration sense; wherein the CO, C1 and C2 are positive real numbers, and C0 (C2 (C1). The touch key control method is simple, selection and cancel of the current touch key can be accurately judged by setting the upper limit threshold value C1 and the lower limit threshold value C2, the vibration unit drives the touch key to generate vibration sense to inform a user of the selection condition of the current touch key, and the user can have better use experience.

Description

technical field [0001] The invention relates to the field of touch keys, in particular to a touch key control method and control system. Background technique [0002] At present, touch buttons are used to control many electronic products and equipment, including automotive electronic products, such as the switch, temperature, and air volume adjustment of automotive air-conditioning devices. [0003] According to the working principle, the touch switch can be divided into two types: capacitive and inductive. The capacitive touch key can accurately detect the effective touch of the finger through the insulating material shell (glass, plastic, etc.) more than 20mm, and can ensure that the sensitivity, stability, and reliability of the product will not be affected by environmental conditions. Changes or changes due to long-term use, and has waterproof and strong anti-interference capabilities, super protection, and super adaptable temperature range. [0004] However, compared ...
