How does a car throttle work?

The working principle of the throttle: the throttle is a controllable valve to control the air into the engine, the gas into the intake pipe will be mixed with gasoline into a combustible mixture, so as to combust to form the work. Accelerator pedal position sensor to the driver needs to accelerate or decelerate the information transmitted to the throttle electronic control unit, ECU according to the information to calculate the corresponding throttle position, send a control signal to the throttle actuator, by the actuator will be opened to the calculated opening position of the throttle. ECU and other electronic control units (such as engine electronic control unit, automatic transmission electronic control unit, etc.) to communicate, according to the obtained throttle position sensor, the throttle is a control valve to control air into the engine. The ECU communicates with other electronic control units (e.g. engine electronic control unit, automatic transmission electronic control unit, etc.), and makes constant corrections to the position of the throttle valve according to the information obtained from the throttle position sensor, the engine speed sensor signal, and the vehicle speed sensor, so that the throttle valve opens to the ideal position required by the driver.
