Electronic throttle control simulation experiment system

The invention relates to an electronic throttle control simulation experiment system. The overseas research of the electronic throttle control system (ETCS) has over twenty-year history, the products prepared by manufacturers are beginning to be put on the market largely and the current generation of the electronic throttle products has been launched. The system of the invention comprises a control circuit, wherein the control circuit comprises a signal acquiring and processing circuit, a MCU, a power drive circuit, a DC motor control driver, an accelerator pedal position sensor (PPS) and an electronic throttle position sensor (TPS); the accelerator pedal position sensor and the electronic throttle position sensor are used to separately input the accelerator pedal control signal and feed back the throttle position signal, the A/D converter of the MCU converts an input analog signal to a digital signal, after the control algorithm calculates control quantity, the control signal is output from a high-speed outl
