AI Technical Summary

Technical Problem

In current technologies for intelligent driving of vehicles, reliability is ensured by setting up a backup controller for a single domain controller. However, this cannot cope with multiple failures of the controller and communication lines, resulting in limited system reliability.

Method used

The system employs a multi-layered redundant interactive system, including a main actuator, a secondary actuator, a main controller, a secondary controller, a main channel, and a secondary channel. Through multi-layered redundancy design, it can still operate normally in the event of multiple failures, ensuring the reliability of signal transmission.

Benefits of technology

It improves the reliability of the vehicle's intelligent driving system under multi-point failure conditions, ensuring that the system can still work normally when multiple points fail, and enhances the system's redundancy and reliability.

Abstract

The application discloses a kind of multilayer redundancy interactive system and method, it is related to automobile technical field, the system includes executor, controller and passage;Executor includes main executor and vice executor, controller includes main controller and vice controller, passage includes main passage and vice passage;Controller is used to when main controller is normal, control signal is sent to executor by main controller;When main controller fails, control signal is sent to executor by vice controller;Passage is used to when main passage fails, the control signal of controller is sent to executor by vice passage;When vice passage fails, the control signal of controller is sent to executor by main passage;Executor is used to when main executor is normal, control signal is received by main executor;When main executor fails, control signal is received by vice executor.The reliability of system is increased.
