Vehicle central lock antitheft method and system
First Claim
1. A vehicle central control antitheft method, comprising:
- performing, by a central control system, identity verification for a remote control via cipher matching;
selecting, by the central control system, an alert status in response to a result of identity verification of the remote control, status of an ignition switch and an action of opening or closing a vehicle door, wherein the alert status comprises a pre-alerting status, an alerting status, an alarm activation status, and an alarm inactivation status;
encrypting, by the central control system, the alert status, and transmitting the encrypted alert status to an engine management system;
receiving and decrypting, by the engine management system, the encrypted alert status transmitted from the central control system, and determining whether the alert status is verified and is an alarm inactivation status;
performing safety authentication between the engine management system and the central control system in bidirectional encrypted communication once the alert status is verified and is the alarm inactivation status; and
permitting, by the engine management, an engine to start after the safety authentication is passed.

Abstract
A vehicle central lock antitheft method and system includes a central lock system which is connected by radio with a remote controller for identity verification using rolling codes (S101, S102), wherein the central lock system chooses a security state (S103) and transmits the security state to an engine management system according to the verification result, the ignition IG status and the door switch status signal indicating opening or closing of the door (S104). The engine management system receives the security state transmitted by the central lock system and verifies the identity of the central lock system by code matching (S106); security identification between the engine management system and the central lock system is carried out by bidirectional encryption communication (S107). The engine management system then decides whether or not to lock the engine according to the result of the security identification.

12. A vehicle central control antitheft system, comprising a remote control, a central control system and an engine management system, wherein:
-
the central control system performs identity verification for the remote control via cipher matching, selects an alert status in response to a result of identity verification of the remote control and status of an ignition switch and an action of opening or closing a vehicle door, encrypts the alert status, transmits the encrypted alert status to an engine management system, wherein the alert status comprises a pre- alerting status, an alerting status, and alarm activation status, and an alarm inactivation status; and the engine management system communicates with the central control system via a data bus, receives and decrypts the encrypted alert status transmitted from the central control system, determines whether the alert status is verified and is an alarm inactivation status, performs safety authentication with the central control system in bidirectional encrypted communication once the alert status is verified and is the alarm inactivation status, and permits an engine to start after the safety authentication is passed. - View Dependent Claims (13)
