Control system and method of power-operated tailgate based on millimeter wave

Abstract

The invention discloses a control system and method of a power-operated tailgate based on millimeter wave, wherein the control system includes a power-operated tailgate control unit, a power-operatedtailgate execution unit and a millimeter wave detection unit; the millimeter wave detection unit acquires a kick signal and transmits the kick signal to the power-operated tailgate control unit; the power-operated tailgate control unit judges the kick signal and sends out an effective command so as to automatically and intelligently control the power-operated tailgate execution unit to execute anaction; it is more comfortable for a user to use, and it is more convenient to control; a millimeter wave sensor of the millimeter wave detection unit includes a millimeter wave control component anda microstrip array antenna for detecting the kick signal; the microstrip array antenna is used to acquire the kick signal. The control system has the advantages of low power consumption, high detection sensitivity and the like, is suitable for detecting a moving target moving at the speed ranging from 0.2 km / h to 10 km / h, and also has the advantages that great abilities to penetrate mist, dust andotherness, great interference resistance and the like.

Description

technical field [0001] The invention relates to the technical field of automobile tailgate control, in particular to an electric tailgate control system and a control method. Background technique [0002] At present, the common opening methods of the electric back door mainly include: remote control key opening, central control switch opening, back door switch opening and kick sensor opening; the main ways to close the electric back door are: remote control key closing , The central control switch is closed, the back door switch is closed, and the kick sensor is closed, which brings convenience to the user. In particular, the kick sensor switch can control the opening of the electric tailgate when it is inconvenient to operate the buttons with both hands. closure. [0003] The traditional kick sensor uses a capacitive tailgate sensor. This capacitive sensor works in two ways: [0004] One is to separate and install the two capacitor strips at different positions at the re...

Problems solved by technology

However, in this solution, since the distance between the two capacitors is relatively close, the interaction between the two capacitors is affected by the inductive capacitance itself, and it is easy to be interfered by foreign objects (rainwater, sludge, etc.), which will cause the mutual influence of the two capacitors to become larger.
