Vehicle anti-theft and anti-cheat cryptographic system

Abstract

The invention discloses a burglarproof deception-proof code system of automobile, which comprises the following parts: CPU, data input and display equipment, alarming device, wherein the CPU connects each original ECU in the automobile; the legal user with two patterns as 'manager' and 'visitor' is stored in the CPU; the system enters 'normal' working pattern when enrolling the system at 'manager' ID; the user can operate automobile normally and sets 'visitor' user and effective driving time; the system can be enrolled to do normal operation within effective driving time preset by user when the user enrolls the system at 'visitor' ID; otherwise, the system can't be enrolled; if the user information is different from the stored user information in the CPU, the system enters 'burglarproof alarm' working pattern to trigger alarming device without starting automobile. The invention not only has reliable burglarproof ability, but also possesses unique robbery-proof function.

Description

【Technical field】 [0001] The invention belongs to the field of automobile electronic anti-theft, in particular to a vehicle anti-theft and anti-fraud password system. 【Background technique】 [0002] Along with popularizing of automobile, car theft phenomenon becomes serious day by day. The current vehicle anti-theft technology generally has three categories: one is the traditional electronic anti-theft alarm device, which has poor anti-destructive ability and low safety; the second type is the wireless-controlled anti-theft device, which is easily affected by the environment ( Such as vehicle vibration) and false alarms are generated, and this type of device needs to carry an additional remote controller, which is very inconvenient; the third type is a fingerprint recognition anti-theft device, which has a complex structure and high cost, and is difficult to meet the anti-theft requirements for renting and borrowing cars. deceive demand. In addition, the act of defrauding ...

The current vehicle anti-theft technology generally has three categories: one is the traditional electronic anti-theft alarm device, which has poor anti-destructive ability and low safety; the second type is the wireless-controlled anti-theft device, which is easily affected by the environment ( Such as vehicle vibration) and false alarms are generated, and this type of device needs to carry an additional remote controller, which is very inconvenient; the third type is a fingerprint recognition anti-theft device, which has a complex structure and high cost, and is difficult to meet the anti-theft requirements for renting and borrowing cars. Cheat demand

In addition, the behavior of defrauding vehicles by renting and borrowing cars is also very rampant, but there is no good way to solve this problem at present
