FlexRay, as a communication protocol for automotive
control systems, is developed to fulfill the increasing demand on the
electronic control units for implementing systems with higher safety
and more comfort. In this work, we study the impact of
radiation-induced soft errors on FlexRay-based steer-by-wire system.
We injected the soft errors into general purpose register set of FlexRay
nodes to identify the most critical registers, the failure modes of the
steer-by-wire system, and measure the probability distribution of
failure modes when an error occurs in the register file.
