Throttle Control System in Today
At present, although some domestic high-class cars, such as Bora, Audi, Passat, POLO, Hongqi, etc., have been equipped with electronic throttle control systems, they all belong to foreign-introduced technologies and have little knowledge of their core technologies. Fortunately, over the years, China FAW Group has developed an electronic throttle control system and applied it to the Hongqi HQ3 premium sedan. In addition, some domestic universities have carried out research on electronic throttle control systems and achieved phased results. For example, Jilin University's development of automotive electronic throttle controllers has realized the dynamic response of controllers to meet design specifications; Hunan University carried out research and development of electronic throttle controller based on OSEK/VDX, and constructed electronic throttle hardware and software architecture based on POW-EROSEK embedded operating system; Beijing Institute of Technology carried out rapid control prototype design of electronic throttle fuzzy controller.
Integration and integrated control are not only the development direction of electronic throttle control system, but also the development direction of automotive electronic control system in the future. It helps simplify electronic throttle control systems, reduce manufacturing costs, and enhance information exchange between systems. Currently, ETC has evolved toward integrated and centralized control, such as integration of idle speed control, cruise control, reduced shift shock control, throttle return control and vehicle stability control. Or the brake anti-lock control system, the traction control system and the drive anti-skid control system are integrated to perform the brake control.
