What is the working principle of electronic throttle?

[EvaMarie]

Electronic throttle works by controlling the opening of the throttle valve through cables or wiring harnesses to achieve automatic control function. It replaces traditional throttle cables or rods with wiring harnesses or wires, installing a micro motor at the throttle valve to drive its opening - this is known as drive-by-wire, where wires replace the original mechanical transmission mechanism. Advantages of electronic throttle: 1. It can accurately interpret the driver's intention based on the details of throttle pedal movement, enabling precise control; 2. High stability, less prone to stalling or jerking. The electronic throttle control system mainly consists of throttle pedal, pedal position sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator.
