Bus Guardian for FlexRay
Original language description
The FlexRay [1] is a new communication protocol for the safety-critical real-time applications in automotive. The node-local bus guardian (BG) is used for higher safety and also is responsible for enabling/disabling the media access and error detection.This paper describes hardware implementation of a node-local bus guardian into the field-programmable gate array (FPGA) Cyklone. An improved behavior of BG in the dynamic segment has been introduced and documented. This work is a part of research dealingwith the reliability of x-by-wire systems in automotive. The main object of the bus guardian is supervision of CC which includes channel protection against unauthorized access of CC during diverse protocol operation control states - wakeup, startup, normal active, normal passive and halt. The BG consists of five main blocks described below.
