Abstract

The invention relates to a vehicle integrated data processing method capable of realizing real-time failure switching, which comprises the following steps: 1. building a system hardware platform; 2. electrifying the system; 3. determining a main control module; 4. establishing a periodic task; 5. determining whether the modules are normally self-checked; 6. starting the application task; 7. determining whether the modules have failure or receive manual control commands; executing the failure processing procedure; 9. executing switching command response; and 10. ending. The invention solves the technical problems that the existing vehicle integrated data processing system and method have low reliability, can not realize real-time switching during failure, and have complicated structure and large volume. Adopting a 1plus 1 backup method, the invention greatly enhances the reliability of the system, can realize the real-time switching of the modules and can ensure simple structure and small volume of the system.

Description

Technical field [0001] The invention relates to a data processing method that can realize real-time failover. Background technique [0002] The existing vehicle integrated data processor (VIDP) generally includes a central processing unit module, a multimedia module, a power supply module, a real-time control module and a public interface module. In order to improve the reliability of the vehicle integrated data processor system, a backup method is generally adopted. , That is, two sets of identical vehicle data processors are used, and if one of the processors fails, it will switch to the other system. However, this method has the following disadvantages: [0003] 1. Low reliability. If two sets of complete machines fail one after another, the entire system cannot work. [0004] 2. Since the two mutually backup systems are physically separated from each other, when the main control machine fails, the backup machine cannot know the previous working status and data of the main cont...
