Abstract

The intelligent driving system for new energy vehicles consists of steering by wire, braking by wire, shift by wire, and accelerator by wire. Chassis by wire technology is a key technology involved in intelligent driving of new energy vehicles, and is also an effective support for promoting the continuous updating and development of intelligent driving. It is a hot issue in the research, development and manufacturing of new energy vehicles at this stage. Chassis by wire technology is a key technology for the update and development of intelligent driving of new energy vehicles, and is an inevitable choice for intelligent driving of future vehicles. The application of chassis by wire technology has changed the complex mechanical connection equipment, hydraulic, pneumatic and other components in the past, greatly promoting the improvement of energy efficiency and the sustainable endurance of new energy vehicles. At present, the consensus in the new energy vehicle industry is "wireless control without autonomous driving", which also well illustrates the important position of chassis by wire technology in the intelligent driving field of new energy vehicles. Based on the author's actual research, the structure of intelligent driving by wire system for new energy vehicles and the basic principle of chassis by wire technology is discussed, and the full vector control chassis by wire technology is analyzed.
