Trunk opening and closing method and keyless entry and start system

Abstract

The invention relates to a trunk opening and closing method and a keyless entry and starting system. The trunk opening method comprises the following steps of receiving a level signal output by a trunk automatic sensing opening system; identifying the level signal; and if the level signal is a preset action signal, transmitting the preset action signal to an automobile body control module; triggering the automobile body control module to judge a locking state; receiving a locking state judging result returned by the automobile body control module; and if the judging result is that a trunk is locked, judging whether a valid intelligent remote key is available within an external antenna detecting range or not within a preset time; and if the valid intelligent remote key is available within the external antenna detecting range, transmitting a trunk unlocking request signal to the automobile body control module; and controlling a trunk opening mechanism to open the trunk through the automobile body control module. According to the trunk opening and closing method and the keyless entry and starting system, provided by the invention, the trunk is automatically opened and closed; the safety of the automatic opening and closing function of the trunk is guaranteed; the range of the applicable automobile models is wide; and automobile purchasing cost is reduced while the convenience for users is enhanced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for opening a trunk, a method for closing a trunk, a keyless entry and start system for opening a trunk, and a keyless entry and start system for closing a trunk.

Problems solved by technology

However, when the car owner holds items with both hands, the car body is dirty or the weather conditions are bad, etc., the above-mentioned method of opening and closing the trunk brings great inconvenience to the car owner.

[0003] In view of the above-mentioned problems, most of the existing technologies realize the automatic opening and closing of the trunk without manual contact through technologies such as voice opening or reversing radar, but their applicable models need to have an electric trunk opening function, which requires car owners Purchasing luxury or even top-end models greatly narrows the scope of customers' choice of cars
