“…When redundant transmissions are required, every node must be built up with two or more TTCAN controllers and application software must be arranged for handling replication. Like FlexRay, the FlexCAN [10][11][12] architecture has been designed to meet requirements of determinism, fault tolerance and reliability, and this has been achieved by adding extra features to CAN. In this paper the FlexCAN architecture is utilized to design the DbW system of the lift truck.…”

This paper describes the design of a drive-by-wire system for a commercial lift truck using the FlexCAN communication architecture. FlexCAN is a recently developed architecture based on the CAN protocol to support deterministic and safety-critical applications. The main features of FlexCAN are its simplicity and ready implementation based on COTS CAN components. The main steer-by-wire design tasks are listed and a description of how each of the tasks was accomplished using the FlexCAN architecture is detailed. A performance evaluation of the design is included.

“…Assuming that at any given instant the primary components are ECU2, CAN2, S1-a, S2-a, A1-a, and A2a, the system operates as follows: when a driver command is sent from the steering wheel, the primary sensor in the hand wheel (S1-a) will send the corresponding signal to ECU2 on both CAN channels. The components actually keep track of which CAN bus is the primary one according to an error detection and recovery mechanism [12] not detailed here. Only ECU2 will perform its functions (calculations) and output its messages on both CAN buses.…”

“…6 provides an appropriate framework for defining several safety protocols and mechanisms, particularly those dealing with reconfiguration after failure detection. In particular, a flexible error detection and reconfiguration protocol has been developed and implemented as part of the proposed architecture [12]. The reconfiguration protocol supports any number of replicated hardware and software components that together select a primary component.…”

“…6 in the CANoe simulator of the entire system according to the safety-critical requirements stated above. are part of the error detection and recovery protocol [12]. As to the failure mode requirements, we tested to see if the system minimizes the occurrence and severity of the failure modes by fault injection (e.g., a fault in a hand wheel sensor for testing failure mode rw-cmd).…”

A hardware and software architecture suitable for a safety-critical steer-by-wire systems is presented. The architecture supports three major failure modes and features several safety protocols and mechanisms. Failures due to component failures, software errors, and human errors are handled by the architecture and safety protocols. A test implementation using replicated communication channels, controllers, sensors, and actuators has been performed. The test implementation uses the CAN protocol, Motorola S12 microcontrollers, and Microchip MCP250XX components with a steering wheel and road wheel simulator. The focus of the paper is on the application level, using system engineering principles which incorporate a holistic approach to achieve safety at various levels.
