Kick control method and system of automobile electric stern door

Abstract

The invention provides a kick control method and system of an automobile electric stern door. The method includes the steps that a first kick sensor is arranged and used for detecting a kick action atthe first height and generating a first waveform according to the kick action at the first height; a second kick sensor is arranged and used for detecting a kick action at the second height and generating a second waveform according to the kick action at the second height; a first rising edge gradient and a first falling edge gradient are obtained through calculation according to the first waveform, and a second rising edge gradient and a second falling edge gradient are obtained through calculation according to the second waveform; and if the difference value of the first rising edge gradient and the second rising edge gradient is smaller than a set threshold value, and the difference value of the first falling edge gradient and the second falling edge gradient is smaller than a set threshold value, a kick induction controller sends a kick stern door opening request signal, so that the vehicle stern door is opened. The use intelligence of an automobile can be improved, and the comfort feeling of a user is improved.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to a kick control method and system for an electric tailgate of an automobile. Background technique [0002] With the increasing intelligence of automobiles, electric tailgates have become the standard configuration of many mid-to-high-end models, and the function of kicking the tailgate has become an application trend. The kick sensor is mainly used to detect the kicking action. When the foot is kicked into the sensing area at the bottom of the tailgate, the tailgate can be opened automatically, bringing an intelligent experience to the user. The existing kick sensor is installed on the inner wall of the rear bumper. When there is a kick action, the control box will collect a waveform with a rising edge and a falling edge through the kick sensor to judge that there is a request to kick the tailgate. Therefore, if there is Small animals passing or staying under the c...
