Publicity! The first batch of 6 companies/product solutions were shortlisted to compete for the annual intelligent driving/chassis award

Entering 2024, the automotive industry is about to usher in a new technological revolution. This new revolution is not only about the intelligent driving model, end-to-end software algorithms and system innovation, but also the integration and further integration and optimization of the intelligent driving system and chassis control to improve the driving experience. For example, the magic carpet suspension is a typical fusion case, which is based on the integration of intelligent driving perception and air suspension system to achieve functional upgrades.

At the same time, the intelligent driving system is also shifting from functional competition to experience competition cycle. According to the monitoring data of the Gaogong Intelligent Vehicle Research Institute, from January to June 2024, 580,700 new cars equipped with NOA were delivered as standard in the Chinese market (excluding import and export), a year-on-year increase of 177.05%, and the pre-installation rate was 6%.

Whether it is Huawei's Turing chassis, Geely's AI digital chassis, or Zhiji's Lingxi digital chassis, they all emphasize new competitiveness such as multi-modal fusion perception and intelligent body collaborative control, further improving driving safety, and greatly enhancing comfort and stability.

Another set of data shows that from January to December 2023, 7,957,700 new cars were delivered to passenger cars (excluding imports and exports) in the Chinese market, a year-on-year increase of 60.31%, and the installation rate rose to 37.68%; Among them, the assembly rate of new energy vehicles is more than 80%.

At the same time, from the supply chain level, higher requirements are also put forward for relevant participants. On the one hand, intelligent driving solution providers need to further strengthen the integration ability of chassis control and the optimization of motion control algorithms. On the other hand, for chassis-by-wire suppliers, whether it is steering, braking or suspension systems, there is also a need for further integration of body perception and dynamic control capabilities.

In late September 2024, the 17th Gaogong Intelligent Vehicle Developer Conference and Intelligent Driving and Chassis Integration and Upgrading Forum will focus on the upgrade of intelligent driving experience and the comprehensive wire-controlled chassis "tuyere", and the annual intelligent driving/chassis benchmarking product solutions and supplier awards will also be awarded at the same time.
