The invention relates to a burglary prevention verifying method and system of a hybrid vehicle. The burglary prevention verifying method includes a digital code stream generating step, a first digital code stream operation step, a second digital code stream operation step and a digital code stream comparing step. The digital code stream generating step includes that a driving motor and a bidirectional motor generate a digital code stream A1 and a digital code stream A2 respectively to the CAN (controller area network) communication network; the first digital code stream operation step includes subjecting the digital code stream A1 and the digital code stream A2 to first rule operation to obtain a digital code stream B1 and a digital code stream B2 correspondingly; the second digital code stream operation step includes that the driving motor and the bidirectional motor subject the digital code stream A1 and the digital code stream A2 to second rule operation respectively to obtain a digital code stream B1' and a digital code stream B2 respectively; the digital code stream comparing step includes comparing whether or not the digital code stream B1' and the digital code stream B2' are identical with the digital code stream B1 and the digital code stream B2. By means of the burglary prevention verifying method, safety of burglary prevention verification can be improved, and burglary prevention verification time is shortened.
Description
technical field [0001] The invention relates to an anti-theft verification method and an anti-theft verification system of a hybrid vehicle, in particular to a starting mode of a hybrid vehicle with the participation of a secondary anti-theft function. Background technique [0002] The car anti-theft verification function is divided into two levels, the first level is the anti-theft verification of the key, and the second level is the anti-theft verification of the driving parts. Any one of the first-level anti-theft verifications does not pass the vehicle and will not start. [0003] For traditional automobiles and hybrid electric vehicle systems, there is no difference in the first-level key anti-theft verification process, but the second-level anti-theft verification process for the power source and the subsequent system start-up process are different. [0004] The anti-theft verification process of the traditional vehicle system is verified between the engine controller...
