Abstract

The present invention provides a functional safety monitoring device and method for a communication chain of an intelligent driving vehicle software architecture. The functional safety monitoring device includes a functional safety monitoring module, and the functional safety monitoring module includes a service layer diagnosis function module, an ECU abstraction layer diagnosis Function module, MCU abstract layer diagnosis function module, the first failure processing module, the second failure processing module, the third failure processing module, and the emergency operation module; the present invention greatly reduces the The possibility of safety problems due to failure of information transmission, and the ability to know the module that caused the failure, provides essential support for subsequent error correction and improvement of communication links, and the invention can achieve functional safety ASIL D level requirements.

Description

technical field [0001] The invention belongs to the technical field of Autosar software framework of intelligent driving vehicles, and in particular relates to a functional safety monitoring device for communication chain of software framework of intelligent driving vehicles. Background technique [0002] With the rapid development of the automotive technology industry, the trend of automotive communication networking is becoming more and more prominent, especially in the field of intelligent driving, the software complexity is getting higher and higher, and the functional failure caused by the information interaction between software components has attracted increasing attention from all parties. In the communication link (COM module, OS module, PDUR module, interface layer, driver layer), no matter which module fails, it will affect the data transmission of the application layer, which will cause abnormal system signal transmission, and then affect the safe driving of the w...
