Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] see figure 1 , figure 2 and (Note: The curve in the figure represents the farthest effective distance of the remote control and the directivity of the remote control of the whole vehicle in the 360° range around the car)

[0017] , the technical scheme of the test method of the vehicle remote control performance of a kind of car remote control key access control system of the present invention is: carry out according to the following steps:

[0018] The first step is to select an open field test site; the open field test site 3 requires that there are no obstacles 20 cm above the ground within a range of at least 25 meters by 25 meters;

[0019] The second step is to mark the origin of the coordinates and make a test circle; mark the origin of the coordinates at the center of the open field test site 3, and use this as the center of the circle to pull out a l...

Abstract

The invention discloses a test method for a finished automobile remote control performance of an automobile remote control key access control system. The technical scheme is as follows: the method is implemented through the following steps: 1. selecting an open area test site; 2. signing an origin of a coordinate, and making a test circle; 3. putting a tested automobile; 4. installing a test instrument; 5. testing the finished automobile remote control performance; and 6. plotting to judge the remote control performance. According to the test method, the finished automobile remote control performance can be tested in an open area without a large professional automotive antenna test darkroom so as to greatly lower the cost of the finished automobile remote control performance; meanwhile, the measurement result is real and effective and can directly represent the finished automobile remote control directivity and effective remote control distance of the remote control key access control system; the open area can be selected according to the practical situation; and test positioning and signal measurement are both finished by simple equipment, so that the test method is convenient to operate and has good flexibility, and the test efficiency is greatly improved.

Description

technical field [0001] The invention belongs to a test method for automobile electronic components, in particular to a test method for the vehicle remote control performance of a car remote key access control system (RKE). technical background [0002] Car Remote Keyless Entry (RKE, Remote Keyless Entry), as a technically mature car radio frequency electronic component, has basically become the standard configuration of various models on the market. Car users' demand for the car remote key access control system is no longer just the realization of functions, but more attention is paid to the reliability and convenience of remote unlocking and locking. Due to the complexity of the metal structure of the vehicle and the electromagnetic environment inside and outside the vehicle, it will affect the remote control performance of the remote control key access control system. As a vehicle manufacturer, it is necessary to verify the reliability of the remote control performance of ...
