On Monday, BYD unveiled DiSus (“Yunnian” in Chinese), an electric-powered body control suspension system that it claims is the primary complete Chinese resolution for vertical car dynamics. Overseas automakers have already mastered an identical technology for his or her inner combustion automobiles.
The Chinese electrical car pioneer plans to scale the technology to varied fashions throughout its Dynasty and Ocean lineups, in addition to premium sub-brands together with Yangwang and Denza, because it expands its presence within the luxurious automobile phase.
Why it issues: BYD Chairman Wang Chuanfu mentioned that the corporate’s latest-iteration suspension system is about to “fill the gaps” China has in dealing with core useful capabilities comparable to driving dynamics and chassis control (our translation).

- Another variant makes use of adaptive dampers and air springs to cut back vibrations and preserve the trip easy, and the car’s trip top will be adjusted by 150 mm to assist passengers out and in of the automobile.
- The system additionally guarantees to supply excessive vertical dynamics capabilities, as body roll throughout cornering and cargo adjustments will be lower down, which the corporate hopes to make use of to realize a big edge within the luxurious Chinese client phase.
- The Chinese title of the system “Yunnian” combines “Yun,” which refers to clouds, and “nian,” which refers back to the highest degree of carriage in historical China, reserved just for emperors and concubines.
AI strategies and algorithms: Having traditionally supplied few particulars about autonomous driving and in-car software program, BYD mentioned the body control technology will use a sensor suite and central processor, making the automobile adaptable to sure automated driving functions.
- The outfitted car will be capable to detect objects and potential highway hazards at a distance of as much as 150 meters, whereas algorithms for movement control will enable the suspension to deal with bumps earlier than a wheel even reaches them.
- BYD will first use the technology within the upcoming U8 off-road car beneath the Yangwang sub-brand with a price ticket of greater than RMB 1 million ($150,000), and the Denza N7 crossover set to go on sale later this yr.
- A base model of the system can even be obtainable to house owners by way of over-the-air updates with their high-end variations of the Denza D9 van, the Han sedans, and the Tang crossovers. The firm didn’t give a exact timeframe for the replace.
Context: Vehicle control technology of this type is a mature characteristic in high-end international manufacturers and has been nearly fully dominated by global suppliers comparable to German’s Continental, analysts at Chinese brokerage Essence Securities wrote in a analysis be aware on Oct. 29 final yr.
- Mercedes-Benz launched its Magic Body Control system with a highway sensing system for highway floor detection to its S-Class automobiles in 2013.
