The constitution and working principles of the electronic throttle control system were introduced, and a design of the fuzzy controller of electronic throttle was represented in this paper. In addition, the rapid control prototyping of the fuzzy controller was designed based on the dSPACE GmbH's real-time simulation system DS1103 PPC single controller board. The experimental results indicate the developed fuzzy controller can satisfy the requirements for running practical application of the automotive electronic throttle.
