Abstract

The invention discloses a composite PKE (passive keyless entry) automobile encryption and antitheft system. The composite PKE automobile encryption and antitheft system comprises a base station and a transponder, wherein the base station is arranged on an automobile; and the transponder is arranged on a key of the automobile. The composite PKE automobile encryption and antitheft system is characterized in that the encryption and antitheft system mainly comprises two encryption modes, the first encryption mode is a medium-distance and remote Bluetooth encryption mode, and the second encryption mode is a near-distance encryption mode which is similar to the traditional PKE encryption mode. The encryption and antitheft system comprises the composite remote and near-distance double-encryption mode, random weighting codes are added to perform scrambling on the basis of encrypted rolling codes, the safety of the system is twice greater than that of the traditional PKE encryption system, and the cracking difficulty is greatly increased. Compared with the traditional PKE encryption system, the composite PKE automobile encryption and antitheft system has the advantages that only a Bluetooth wireless communication circuit is added, and because the Bluetooth wireless communication circuit has excellent low-power-consumption characteristic, power consumption can be reduced further in a low-speed breathing mode.

Description

technical field [0001] The invention relates to the technical field of front-mounted and rear-mounted driving anti-theft equipment for automobiles, in particular to a compound PKE encrypted anti-theft system for automobiles. Background technique [0002] The traditional car PKE (keyless entry) encryption anti-theft system, the working mechanism is that the base station (car) first conducts short-distance (1-3 meters) low-frequency (125KHz) inquiry, and the legal transponder (smart key) then passes the high-frequency ( 315 / 433MHz), the encrypted rolling code information is sent back, the base station completes legal identity authentication after decryption, and the vehicle is automatically disarmed. [0003] The traditional car PKE encryption method is well known to everyone, and the possibility of being cracked by criminals is greatly increased. Therefore, it is necessary to develop a new type of composite encryption PKE anti-theft system to improve the safety of future cars...
