Electrostatic capacitor switch unit

Abstract

An electrostatic capacitor switch unit. The present invention provides a capacitive switch device and a control method thereof. The capacitive switch device comprises: a touch sensing unit (100) comprising a sensing electrode (110) and a transmitting electrode (120) disposed on a substrate (2); and a touch control module (200) disposed on the substrate (2) and configured to confirm a touch manipulation state of a operator based on a sensing signal from the touch sensing unit (100) and output a touch output signal, wherein the transmitting electrode (120) outputs a transmission signal in response to a transmission control signal from the touch control module (200), and the sensing electrode (110) detects signals in response to a sensing control signal from the touch control module (200) forbeing applied to the touch control module (200). The touch control module (200) enables the sensing electrode (110) and the transmitting electrode (120) according to a preset mode.

Description

technical field [0001] The present invention relates to a capacitive switching device, and more particularly, to a capacitive switching device having a simplified configuration that allows both smoother operation and compact arrangement for more accurate detection of contact with a human body. Background technique [0002] Vehicles such as automobiles are required to function as various types of convenience tools capable of providing users with a more stable and comfortable driving state, in addition to functioning as moving tools. Accordingly, vehicles are equipped with various conveniences, various types of switches for operating and controlling them, and devices for displaying them. [0003] Various switches are centrally provided at the steering wheel of the vehicle to improve driver's convenience. Depending on the circumstances, the complex physical arrangement of the switches may cause the driver to cause erroneous operations or fix his or her eyes on the steering whe...

AI Technical Summary

Problems solved by technology

In either case, traditional mechanical switches involve issues where capacitive sensors are susceptible to the surrounding environment (e.g., temperature and humidity / magnetic fields)

In other words, when the surrounding environment such as water, magnetic field, and electric field changes greatly suddenly, the existing touch algorithm determines that the human body touches, and there is also a problem that the touch algorithm maintains the state that the human body has been touched until the suddenly changed environment returns to its original state so far
