Abstract

The invention provides a function safety monitoring device and method for an intelligent driving automobile software architecture communication link. The function safety monitoring device comprises afunction safety monitoring module. The function safety monitoring module comprises a service layer diagnosis function module, an ECU abstraction layer diagnosis function module, an MCU abstraction layer diagnosis function module, a first failure handling module, a second failure handling module, a third failure handling module and an emergency operation module. According to the invention, a software architecture BSW layer communication link is monitored; the possibility of safety problems caused by information transmission failure is substantially reduced, modules causing failure can be known,necessary support is provided for subsequent error correction and communication link improvement, and function safety ASIL D grade requirements can be realized.

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...
