Instrumentation for an Urban Series-PHEV Bus With Onboard-Based Sensors and Automotive Network Standards

This paper focuses on the design and deployment of embedded instrumentation fieldbus networks for the monitoring and control of a hybrid urban-transport vehicle. This paper makes a brief introduction of the rationale in the hybrid electric vehicle (HEV) design challenges and states the general features of the “Tempus” city bus. Then, the development tools used are introduced, and these are linked to the implementation of wired controller area networks (CANs) embedded in the vehicle. Before providing a detailed description of some of the designed functions, the “Tempus” operating modes are summarized. Next, for brevity, only the implementation of the three main functions is discussed in some detail as case studies. Finally, the lessons learned, envisaged future work, and the main conclusions are presented.
