Problems solved by technology

However, there are many environmental factors at the rear of the car, such as rain, snow, sand, etc., and the two capacitance bands cannot identify whether there are environmental factors, so the validity of the signal cannot be determined, and the anti-interference ability is low.

Embodiment Construction

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained in conjunction with specific drawings.

[0019] In this example, on the basis of the existing two capacitor bands, the third capacitor is used to bring the signal to detect environmental changes, and the first and second capacitor bands used to sense the kick signal can be sensed. Compensation is carried out to realize the compensation interference signal of the kick sensor under the influence of the external environment to obtain the real signal.

[0020] For the introduced third capacitive strip, it can be directly drawn on the corresponding processor PCB, saving space and material resources, and easy to install. The third capacitive strip can be used to detect the influence of environmental factors such as rain and snow. Compensate the sensing signals of the first and second capacitor bands for sensing...

Abstract

The invention discloses a kick sensor system for a car tail door. The kick sensor system comprises a first capacitive strip and a second capacitive strip which are used for sensing the foot-kicking action and further comprises a third capacitive strip used for sensing environment factors, and a processing module. The processing module collects signals of the first capacitive strip, the second capacitive strip and the third capacitive strip, and conducts correction-compensation on foot-kicking action sensing signals of the first capacitive strip and the second capacitive strip according to thesensed environment factor signals sensed by the third capacitive strip. According to the scheme, false triggering caused by the environment factors can be reduced effectively, and the anti-interference performance of the kick sensor to the environment is improved.

Description

Technical field [0001] The invention relates to sensor technology, in particular to a kick sensor for vehicles. Background technique [0002] Today's automotive electronics technology field is changing with each passing day, and more electronic products have become more and more humanized, satisfying people's pursuit of comfort, safety, intelligence and other factors. For a better user experience, it is more convenient for users to open the tailgate of the car when their hands are full. Now the kick sensor has become the mainstream with its comfort, convenience, and safety features. [0003] At present, there are many sensing methods for kick sensors, such as ultrasonic sensors, microwave sensors, infrared sensors, capacitive sensors, and so on. Capacitive sensors have become mainstream due to their low cost, convenient and quick installation, and low probability of false sensing. [0004] The design of the existing capacitive kick sensor is mainly that two capacitive bands are ins...
