The Detection And Control Research Of Electronic Throttle

Nowadays, the world automobile industry develop on an unprecedented scale. Sincereform and opening, China ’s economic develop at an alarming rate of development, at hesame time，China ’s automotive industry is also accompanied by rapid economic growth inChina and progress. It affects daily a travel to our way of life growingly. however,energyconsumption, environmental pollution, and travel security issues have become increasinglyprominent.Therefore, the research of automobile fuel economy, travel safety and ride comfort willalso be the future direction of development; Auto attendantly its fault detection anddiagnosis are becoming increasingly important. In this paper, we study the electronicthrottle control system, the degree of opening of the throttle valve system is not entirelydependent on the driver’s direct operation of the accelerator pedal, electronic throttlecontrol system according to the current conditions to intervene the opening degree ofvalve timely, to make the engine in the most optimal mode of operation, therebyimproving automobile fuel economy, safety and travel ride comfort and so on.By reading a lot of literature, first of all, I acquaintance the electronic throttle basicworking principle and the main characteristics,and research the current development ofelectronic throttle, relevant content as well as the difficulties that may be encountereddeeply. Summing up the general fault of the throttle causes and conventional detectionmethods. by making physical detector,we detect electronic throttle, in order to determinethe integrity of the internal resistance of the stepper motor idle speed in the motor, anddetect the position sensor of the throttle, as well as electronic throttle signal value at eachangle is normal and judge the throttle valve is catching and so on. Research methods usedto build the model, the use of matlab simulation software to build motor control module,PWM control model and the accelerator pedal position sensor model of the electronicthrottle control system...
