The response request for the gasoline engine throttle system of the hybrid electric vehicle power control unit and the status of electronic throttle system R＆D are analyzed. The PWM control algorithm for electronic throttle system based on fuzzy logic is put forward, and the circuit taking the Infineon TLE6209R chip as the core has been designed. Based on the algorithm and the circuit, the simulation model has been set up by Matlab/Simulink. The rapid control prototyping system with dSPACE is adopted to operate the real-time simulation on different mode, and the simulation result shows that the control algorithm and circuit are all effective. It would be beneficial to develop the product-throttle controller.
