Embodiment Construction

[0054] see Figure 1a and Figure 1b , the example system includes a control module 102 disposed inside a vehicle 101 . The control module is arranged to communicate with the door locking mechanism 103 to lock or unlock the vehicle.

[0055] In the case of smart start, the control module may also provide a signal or command to other electronic modules 104 installed in the vehicle to start the engine.

[0056] The control module 102 may receive some request to perform a particular smart entry or smart start function from the remote transceiver 105 , the door handle 106 , the push start switch 107 , or from other modules installed within the vehicle.

[0057] The control module must detect the presence of the remote transponder within a particular area of ​​the vehicle to determine whether it is necessary to perform a particular smart entry or smart start function.

[0058] see Figure 3a , in the vicinity of the vehicle 101 , there is an example of an area 301 where the pres...

Abstract

The invention relates to a method and a system for passively entering and passively starting an automobile by using an artificial neural network. The method at least comprises the following steps of: transmitting signals from antennas, measuring signal intensity values, and sending the signal intensity values serving as input vectors to the artificial neural network. The system comprises at least three antennas (108), (109) and (110), a control module (102) and a remote transceiver (105), wherein the at least three antennas (108), (109) and (110) are arranged in a vehicle detection area and used for transmitting the signals; the control module (102) is used for receiving the measured field intensity and predicting the position of the remote transceiver; and the remote transceiver (105) is used for measuring the field intensity of each antenna and sending the measured field intensity values to the control module (102). The method and the system can mainly be used for detecting the vehicle detection position area with complex shape, so that the development cost of the system is reduced and the performance of the system is improved at the same time.

Description

technical field [0001] The present invention relates to a method and system for intelligent entry and intelligent starting of automobiles using an artificial neural network. Background technique [0002] Passive entry and passive start systems are well known in the automotive industry for performing vehicle functions, such as locking, unlocking doors, or starting the engine, without requiring an operator to perform specific actions on a remote module. [0003] In currently known smart entry and smart start systems, a remote transceiver, commonly referred to as a "fob" or "card", is provided. Such a remote transceiver could be attached to the key fob as a stand-alone unit, or could be part of the top of the ignition key. The remote transceiver automatically sends radio frequency (RF) signals to the vehicle to perform any of a variety of remote control functions, such as unlocking the doors, starting the vehicle's engine, and / or turning on interior and / or exterior lights. ...
