Under the background of the increasingly serious global energy crisis and environmental problems, governments and enterprises around the world have paid more attention to the development of a new generation of sustainable energy. The fuel cell bus has become an ideal choice for new energy vehicles due to its zero emission, high efficiency as well as long endurance. A fuel cell bus consists of various components, such as fuel cell stacks, power batteries, DC/DC converter, electronic motor and etc. A distributed control system is developed for the fuel cell bus which has been facing many challenges from complex electromagnetic environment, demands of on-line monitoring and diagnosis, wide working temperature range, energy dynamic optimization (EDO) ability and etc. In order to meet the requirements of the challenges, a series of novel electronic technologies have been successfully implemented in the control system, including J2ME based wireless Bluetooth monitoring system for ECU, time triggered in-vehicle networks, EDO-oriented route intelligent recognition by GPS, Hardware-In-the-Loop simulation, seamless automatic code generation and etc. These novel methods and technologies accelerate the development of the control system, shorten the system debugging time, and improve the quality and reliability of the whole control system. This paper presents the application process of these electronic technologies on the vehicle control system for a fuel cell bus, one project sponsored by China 863 Hi-tech Research Program.
