Fault Containment and Error Detection in TTP/C and FlexRay
نویسنده
چکیده
TTP/C and FlexRay are two protocols that have been designed for use in time-triggered systems for safety-critical applications. This paper investigates the fault-containment and error-detection mechanisms of safety-critical time-triggered systems that are based on these two protocols. The following critical failure modes of a fault-containment region are introduced and analyzed in detail: babbling idiot failures, masquerading failures, slightly-off-specification (SOS) failures, crash/omission (CO) failures, and massive transient disturbances. After a short description of the two time-triggered protocols TTP/C and FlexRay this paper tries to show how the two protocols handle these failure modes at the architecture level.

A Comparison of TTP/C and FlexRay
With the announcement of BMW and DaimlerChrysler to 15 develop the new time-triggered protocol FlexRay for safety critical “Xby-Wire” applications, the time-triggered technology is moving into the mainstream of the automotive electronics market. This paper compares the established protocol TTP/C with the new protocol FlexRay from BMW and DaimlerChrysler. This comparison is based 20 on the spars...
متن کاملByzantine Fault Containment in TTP/C
The TTP/C protocol is a communication protocol for safety-critical real-time applications. It is designed to meet both the cost constraints of the automotive industry and the stringent safety constraints of the aeronautics industry. This is achieved by using the static nature of the TTP/C communication pattern to build relatively cheap communication controllers being supervised by guardians tha...
متن کاملAn FSM-based monitoring technique to differentiate between follow-up and original errors in safety-critical distributed embedded systems
Nowadays, distributed embedded systems are employed in many safety-critical applications such as X-by-Wire. These systems are composed of several nodes interconnected by a network. Studies show that a transient fault in the communication controller of a network node can lead to errors in the fault site node (called original errors) and/or in the neighbor nodes (called follow-up errors). The com...
متن کاملFault Tolerance Evaluation Using Two Software Based Fault Injection Methods
A silicon independent C-Based model of the TTP/C protocol was implemented within the EU-founded project FIT. The C-based model is integrated in the C-Sim simulation environment. The main objective of this work is to verify whether the simulation model of the TTP/C protocol behaves in the presence of faults in the same way as the existing hardware prototype implementation. Thus, the experimental...
متن کاملStudy the Effect of Soft Errors on FlexRay-Based Automotive Systems
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 ...
