The rapid development of modern automotive electronics technology has been promoted by social demands, laws and regulations and the progress of electronic technology. The technology of wire drive is one of its main directions. Electronic throttle control
is a part of automotive power control system. It plays an important role in automotive power and driving control.
With the development of automotive electronic control technology, electronic throttle control system
(ETCS) is one of the modern engine electronic control technologies, which is widely used in automotive dynamic control systems such as idle speed control, drive anti-skid control, cruise control and automatic transmission control. ETCS replaces the traditional mechanical throttle operating system, which is the trend of automobile development. At present, the research on this technology has been very thorough abroad, and the domestic research is still in its infancy. Throttle is affected by spring reset torque, damp torque, intake disturbance and viscous friction torque, motor drive torque in the working process.
