Problems solved by technology

However, in this solution, due to the short distance between the two electrodes, the interaction between them is caused by the inductive capacitance, and it is easy to be interfered by foreign objects (rainwater, sludge, etc.), which will cause the mutual influence of the two capacitances to become larger.
prone to failure in complex environments

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] This example scheme abandons the original technical design concept that at least two capacitive sensor electrodes are integrated on one capacitive strip, adopts a capacitive strip, and only integrates a single (one) capacitive sensor electrode on it, and further forms The capacitive kick sensor, the capacitive kick sensor formed from this, effectively solves the unnecessary interference caused by the double electrodes that are too close; action recognition.

[0021] see figure 1 , which shows the system block diagram of the capacitive kick sensor provided in this example. It can be seen from the figure that the capacitive kick sensor 10 has a single capacitance strip and single electrode structure, and is specifically composed of a sing...

Abstract

The invention discloses a capacitive kick sensor, comprising: a single board computer, a processor, which only has a single capacitance band and a single sensing electrode, the single sensing electrode is integrated on the single capacitance band, and the capacitance band is connected to the processing device. This solution effectively solves the problem of ensuring the triggering performance of the kick sensor and improving the reliability of the sensor in different environments under the premise of reducing the installation conditions.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to a tailgate sensor. Background technique [0002] At present, automotive electronics are developing rapidly, and comfortable electronic products have gradually become an indispensable part. Car tailgate sensor is one of them. After many years of introduction and elimination of various solutions, capacitive tailgate sensors are widely used because of their simple implementation, sensitive sensing, and low cost. [0003] In the capacitive tailgate sensor, there are currently two options: [0004] One is to install the two capacitor strips separately at different positions at the rear of the car, and the two positions simultaneously sense human body movements. This solution has a high recognition rate, but because it is installed in two locations, and the capacitor strap itself has high requirements for the installation environment (away from metal, anti-static paint, etc.), it ...
