China-based EV maker BYD unveiled its DiSus Intelligent Body Control System designed for new energy vehicles (NEV) on April 10. The system, which features vertical motion control, will be available on several models across the company's four brands.
While luxury brands like Mercedes-Benz and Audi have their unique body control systems, BYD is the first Chinese automaker to develop the technology, according to chairman and president Wang Chuanfu.
BYD said DiSus is a comprehensive system of perception, decision-making, and execution focusing on vertical motion control to improve the driving experience. The system can minimize a vehicle's risk of rollover and reduce the displacement of occupants during high-speed cornering, full-throttle acceleration, or emergency braking, the company added.
The DiSus system consists of three branches - DiSus-C, DiSus-A and DiSus-P. According to CnEVPost, the DiSus-C can receive thousands of signal inputs every second. With the high-speed processing of the DiSus intelligent computing center, the system can enable rapid damper adjustment.
DiSus-P is the most advanced among the three branches, CnEVPost reported. BYD claimed it is the world's first intelligent hydraulic body control system. The DiSus-P suspension can lift four wheels simultaneously. It can also trigger the third-stage stiffness in an emergency to reduce the impact load by 50%.
BYD said the DiSus system will protect cars from scratches or damage under snowy, muddy, or flooded road conditions. The company will put the system into several models of the BYD brands DENZA, Yangwang, and a new professional and personalized brand it will introduce to the market in the summer of 2023. But the carmaker did not specify the time the system will be available.
Wang has said BYD is targeting 3 million vehicles in sales this year, aiming to become the largest Chinese automaker by the end of 2023.
According to Reuters, the announcement of the self-developed body control system showed BYD's intention to expand to the premium market. Currently, most of the company's cars are priced below CNY300,000 (US$43,641), which is considered the mass market segment.
