Application of CAN message timing analysis to system-level fault diagnostics and networked control in vehicles

This paper first discusses deterministic and stochastic characteristics of CAN message response times. They are then extended to depict system behaviours by featuring CAN message traces, which helps develop a system-level fault diagnostic method to address the increasing complexity of vehicles. These characteristics are also applied to formalize in-vehicle control systems which are made networked and distributed due to the vehicle complexity.
