Time-triggered CAN, implementations, development and testing tools

The Controller Area Network (CAN) has seen enormous success in automotive body and powertrain control systems, and in industrial automation systems using higher layer protocols such as DeviceNet and CANopen. Now, the CAN standard ISO11898 are being extended to Time Triggered CAN (TTCAN) to address the safety critical needs of first generation drive-by-wire systems. However, their successful development depends upon the availability of silicon and software support, and appropriate development & analysis tools. This paper outlines some of the exciting developments at Warwick Control Technologies which includes:a) An implementation that can run deterministically at 60% bus loading at 1Mbit/s and 70% at 500Kbit/s (almost twice that of traditional automotive CAN systems), b) Interoperability testing with the Bosch c) Rapid control prototyping for a TTCAN Embedded Node, and d) TTCAN transmitter/fault injector tool.
