Intelligent chassis technology

Intelligent chassis technology helps new energy vehicles to be equipped with intelligent control centers, focusing on the future development direction.

Automatic driving is the only way for the development of automobile technology in the future; Meet the needs of "resources" vs "travel"; The popularization of autonomous driving requires the integrated development of chassis wire control technology and domain control technology. The development of intelligent and autonomous driving promotes the development of intelligent chassis technology; Intelligent chassis is a necessary condition to realize high-level automatic driving and an important carrier of intelligence.

Intelligent chassis provides a bearing platform for automatic driving system, cockpit system and power system, and has the ability to identify, predict and control the interaction between wheels and the ground and manage its own running state, thus realizing the intelligent driving task of vehicles. The execution response time and execution accuracy of the by-wire control system require multi-level safety backup design after the main system fails;

Safety-oriented related technical requirements are as follows: (1) Have a safety degradation mode that meets the relevant ASIL level requirements; Redundant unit takeover correlation; Requirements for timeliness and redundancy of communication; Soft-hard decoupling technology requires the boundary definition and power-responsibility division of fusion control; System compatibility design; Interface design of anti-interference design subsystem of the system; Functional security, expected functional security and network information security, combined with the relevant safety technical requirements of "chassis operation foundation" and "intelligent technology bearing", the corresponding safety standards are constructed and expanded to guide the safe development and operation of intelligent chassis. Focus on the user experience brought by the integration of wire control and domain control.

Industry standards should be established according to relevant technical indicators and requirements to promote the healthy development of intelligent chassis technology. Based on the national "double carbon" strategic goal, the low-carbon design of intelligent chassis is imperative. It is suggested that industry standards should be established for key indicators and technical requirements, and relevant national emission standards should be optimized, so as to constrain the development, production and operation of the industry, conduct standard research and ranking for key projects, and check for missing items, especially those that have not yet established standards.
