Problems solved by technology

[0003] The disadvantages of the above technical solutions are: it takes a period of time from the keyless entry button (or capacitive sensor) on the door handle being triggered to the unlocking of the car door. The time for a single two-way communication is generally 125ms, and for two times it is 250ms. Smart key positioning Once, the validity of the smart key is verified once), if the act

Embodiment Construction

[0034] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0035] see figure 1 , the embodiment of the present invention, a kind of automobile keyless entry system detection method, comprises the following steps:

[0036] S1. The mobile terminal is bound to the car controller;

[0037] S2. The mobile terminal obtains and stores the GPS position information of the vehicle controller;

[0038] S3. The mobile terminal monitors in real time according to the GPS location information and judges whether the distance between the car and the mobile terminal is less than a first preset distance;

[0039] S4. If the distance between the car and the mobile terminal is less than the first preset distance, the mobile terminal remotely wakes up the car controller to perform smart key detection;

[0040] S5. T...

Abstract

The invention discloses a keyless entry system detecting method for an automobile. The keyless entry system detecting method for the automobile comprises the following steps that a mobile terminal is bound with an automobile controller; the mobile terminal acquires GPS position information of the automobile controller; the mobile terminal judges whether the distance between the automobile and the mobile terminal is less than a first preset distance or not according to the GPS position information; if the distance between the automobile and the mobile terminal is less than the first preset distance, the mobile terminal remotely wakes up the automobile controller to execute intelligent key detection; the automobile controller judges whether the distance between the automobile and the intelligent key is less than a second preset distance or not; if the distance between the automobile and the intelligent key is less than the second preset distance, the automobile controller performs intelligent key authentication and finishes the intelligent key authentication process; and if the time of keeping the distance between the automobile and the mobile terminal within the first preset distance exceeds a preset time, the automobile controller exits the intelligent key authentication process. According to the invention, the loss of the system is reduced and the practicability, convenience and safety of the system are improved.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, and in particular relates to a method for detecting a keyless entry system of an automobile. Background technique [0002] At present, the car keyless entry system has been widely used in mid-to-high-end models. The technical solution is: taking the driver's door keyless entry as an example, a low-frequency antenna (125KHz) and a keyless entry button are installed on the driver's door handle. (or capacitive sensor), after the keyless entry button is pressed or the door handle is detected by the capacitive sensor, the keyless entry control unit (integrated base station, including low-frequency signal transmission and high-frequency signal reception functions) is triggered to transmit through the low-frequency antenna Give the smart key (integrated transponder, including low-frequency signal receiving and high-frequency signal transmitting functions) a positioning signal, and the sma...
