Brief introduction of electronic throttle

Among the internal components of motor vehicles, the device that controls the fuel supply of internal combustion engine is called throttle. Its function is to manipulate the throttle opening to control the flow of combustible mixture and change the speed and power of the engine to meet the needs of automobile driving.

The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. However, the application of this traditional throttle valve is limited and lacks accuracy. With the rapid development of automotive electronic technology, Electronic Throttle (EGAS) came into being.

Electronic throttle is an electronic control device that transmits the signal of the depth and speed of stepping on the throttle through a position sensor, so as to realize the throttle function. This signal will be received and interpreted by the on-board microcomputer, and then a control command will be issued, requiring the throttle to open the angle it should open quickly or gently according to the command. This process is accurate and fast. There will be no mechanical wear problem.

Electronic throttle control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator.

The displacement sensor is installed in the accelerator pedal to monitor the position of the accelerator pedal at any time. When it is detected that the height position of the accelerator pedal changes, the information will be sent to the ECU instantly. The ECU will calculate and process these information and data information from other systems to calculate a control signal, which will be sent to the servo motor relay through the line. The servo motor drives the accelerator actuator, and the data bus is responsible for the communication between the system ECU and other ECU.
