Remote-control no-key system for automobile and data processing method thereof

Abstract

The invention discloses a remote-control no-key system for automobiles and a data processing method thereof. The system is composed of an induction key system and a vehicle-mounted control system and is characterized in that the induction key system is composed of an LF (lower frequency) receiving coil, a key central processor, a key base station processor, a transponder, a storage and a UHF (ultra high frequency) key antenna module; the vehicle-mounted control system is composed of an LF emission coil, a UHF vehicle-mounted antenna module, a central door inductor, an igniter, a vehicle-mounted central processor, a vehicle-mounted base station processor, a door lock controller, a central lock controller and an engine control system. When data is processed, a communication link for identity authentication is is required to be built between the vehicle-mounted control system and the induction key system to open the door lock and ignite the engine. Even if people break into the vehicle, the vehicle engine can not be ignited without the key, so that the burglar-proof performance of the vehicle is greatly improved, and the automobile also has the function of one-button starting.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a keyless remote control system for automobiles and a data processing method thereof. Background technique [0002] With the development of technology, there are many keyless car entry systems, but many old-fashioned car systems do not have the function of long-distance car induction system. In order to have the function of the keyless entry system, many technology manufacturers have improved the original car. The method adopted is: cut off the connection line between the induction coil and the control circuit of the anti-theft control lock (base station) part of the original car, and take out the induction coil. At the same time, insert the original car key into the induction coil, and put it in the hidden place of the car together with the transponder. In this way, as long as the car owner connects the connecting wire between the anti-theft controlle...

Problems solved by technology

[0003] However, although this modification method realizes one-key start of the car, because the transponder is placed in the car, the thief can also drive the car away as long as the connection line is connected, so the anti-theft performance of the car is reduced.
