Research Status of Electronic Throttle

The research of electronic throttle originated in 1970s, and the products came out in 1980s. Over the years, foreign research on electronic throttle has made very rapid development. The development trend can be summarized as follows: the control strategy develops from linear control to nonlinear control, from auxiliary electronic throttle to independent electronic throttle system, from single control function to integrated development of multiple control functions, taking into account the improvement of power, economy, handling stability, emission and ride comfort.

Many foreign companies have carried out in-depth research and development of electronic throttle system, such as Bosch, Pierberg, Delphi, Visteon, Toyota, Hitachi, Denso, Ma Ruili and so on. , they launched a series of products aimed at various brands of high-end cars. Although some domestic cars such as POLO are also equipped with electronic throttle system, there is no systematic and in-depth research on ETC and no mature products.

At present, some luxury cars in China, such as Bora, Audi, Passat, POLO and Hongqi, have been equipped with electronic throttle control systems, but they are all imported technologies, and little is known about their core technologies. Fortunately, in recent years, China FAW Group Corporation has developed an electronic throttle control system and applied this technology to Hongqi HQ3 luxury car. In addition, some universities in China have carried out research on electronic throttle control system, and achieved phased results. For example, Jilin University has developed an electronic throttle controller for automobiles, and the dynamic response of the controller meets the design index. Hunan University has developed an electronic throttle controller based on OSEK/VDX, and constructed the software and hardware architecture of electronic throttle based on POW-EROSEK embedded operating system. Beijing Institute of Technology designed a fast control prototype of electronic throttle fuzzy controller.
