Embodiment Construction

[0067] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0068] according to figure 1 and figure 2 , the present invention includes an automobile electronic control host 1 and a remote controller 2 installed in the automobile, the automobile electronic control host 1 is connected with five antennas L1, L2, L3, L4, L0, and the automobile electronic control host 1 includes a position Judgment module 10.

[0069] Such as figure 1 As shown, the remote controller 2 can receive low-frequency signals from the antennas L1, L2, L3, L4, and L0, and send radio frequency signals to the vehicle electronic control host 1.

[0070] Such as figure 2 As shown, the end of the car body, that is, the middle part of the front end and the rear end are respectively placed with antennas L1 and L3, the antenna L1 in the middle of the front end of the car body is placed at the instrument panel of the cab, and the antenna L3 in the ...

Abstract

The invention relates to an automobile control method with remote control identification, relating to control and comprising the following steps: A. by taking an automobile body as a point of origin, four coordinate quadrantal subareas are divided, and two terminal antennae and two side antennae are respectively positioned on two coordinate axes; B. an automobile electrical control host machine receives trigger signals and starts position detection control, a position judging module acquires corresponding detection intensity data of each antenna; C. the position judging module judges the position of a remote controller or the subarea where the remote controller is positioned by utilizing the maximum calibration value of the central antenna as a reference value and utilizing the detection intensity data of each antenna; D. the position judging module judges the position of the remote controller by taking the automobile body corner end of the subarea as a reference point and combining the reference point with the antenna detection intensity data of the subarea, and each subarea comprises a terminal antenna, a side antenna and the central antenna; and E. the automobile electrical control host machine carries out corresponding operation according to the position judging result of the judging module. The method has strong reliability and operability, and good universality.

Description

technical field [0001] The invention relates to control, in particular to an automobile control method with remote control identification. Background technique [0002] Car anti-theft devices have been widely used in the automotive industry. For example, each time you open the door, you must first release the anti-theft device. In use, the anti-theft device can only be released after the user presses the unlock button on the remote control. At this time, the car door can be opened. The operation process is relatively cumbersome, which makes users feel inconvenient. [0003] Hands-free access control system (Passive Keyless Entry) PKE system is based on the ordinary anti-theft technology, adding remote control car inside and outside identification technology, when the user carries the remote control, he can directly press the button on the door handle to open the car door without taking out the remote control device, which provides great convenience to users. [0004] Its b...
