BYD DiSus Intelligent Body Control:

Electric vehicles have transformed how we think about power and environmental responsibility. But as EVs grow in performance and capability, a new expectation has emerged: the ability to deliver both thrilling dynamics and first-class comfort—in every scenario from city highways to rugged off-road terrain. Meeting these demands requires more than a strong battery or motor. It requires intelligent control over the entire vehicle body.

That is the mission behind BYD’s DiSus Intelligent Body Control System, known in Chinese as 云辇 (Yun Nian)—a name inspired by the mythical concept of “riding the clouds.” More than a suspension upgrade, DiSus is a complete, AI-driven chassis solution engineered to keep the vehicle stable, occupants comfortable, and driving confidence high on any road surface.

1. The Purpose: Making Stability Intelligent

Traditional vehicles rely on passive suspension components that react mechanically to bumps, roll, and weight transfer. Electric vehicles accelerate faster and carry heavier battery packs, making old suspension strategies less effective.

DiSus introduces intelligence into the equation. It actively analyzes driving conditions, predicts body motion, and adjusts in real time—creating a smooth and controlled experience far beyond passive systems.

Three Core Benefits

• Better comfort — reduces body movement from potholes and uneven surfaces
• Better handling — keeps the vehicle flatter and more responsive in corners
• Better safety — enhances control during extreme maneuvers or emergency situations

Where a conventional suspension reacts, DiSus proactively manages stability.

2. A Scalable System with Three Technical Levels

BYD has developed DiSus as a modular and scalable body-control platform:

*Adjustment range depends on model configuration

Each system uses high-precision sensors and central computing but targets different vehicle segments—from mainstream SUVs to flagship luxury models.

3. How DiSus Works: Fusing Data, Speed, and Smart Control

At the heart of DiSus is a fast-response sensing and control mechanism:

• Vehicle accelerometers measure body motion
• Wheel-speed detectors track traction and ground reaction
• Cameras and radars recognize road surfaces ahead*
• High-speed processors execute adjustments within milliseconds

*Forward road preview first implemented on Yangwang models, and expanding to premium BYD and Denza vehicles

The Result

• Reduced nodding during acceleration and braking
• Lower body roll during cornering
• Softer absorption of sudden road impacts
• Constant wheel contact for better grip and stability

This makes the cabin stay balanced—not tossed around—whether quickly changing lanes or traveling on challenging terrain.

4. Technology Breakdown: C, A, and P

DiSus-C — Intelligent Damping Control

Used in models like Song L and Sea Lion series

• Electronically adjustable shock absorbers
• Improves both comfort and handling
• Greatly enhances high-speed stability and long-distance comfort

DiSus-A — Intelligent Air Suspension

Used in vehicles like Denza N7 and high-trim BYD models

• Adjustable ride height for comfort, aerodynamics, and off-road clearance
• Supports automatic leveling when passengers enter/exit
• Enhances energy efficiency on highways by lowering stance

DiSus-P — Fully Active Hydraulic Control

Flagship level, first seen in Yangwang U8

• Motor-driven hydraulic pumps independently control each wheel
• Capable of lifting a single wheel or even all wheels for floating mode stability
• Strong vertical control keeps cabin flat even in 3-wheel support conditions

This is the system that enables U8 to perform vehicle drift control, crab walks, and stable driving in tire-loss emergencies—setting new standards for global body control performance.

5. Unique Advantages vs. Global Competitors

While air or adaptive suspensions exist in luxury brands like Mercedes E-ABC, Audi eABC, and Tesla air suspension, BYD takes a different approach:

Conclusion: DiSus offers luxury-segment capability across more models at a broader market scale.

6. Driving Scenarios Designed for Real Needs

DiSus isn’t just for luxury comfort—it improves confidence in all types of driving:

• Urban Roads: Smooth handling over speed bumps and potholes
• Highway Speeds: Flatter body control and reduced “floaty” sensation
• Winding Roads: Strong anti-roll improves cornering precision
• Off-road Trails: Extra ground clearance and enhanced wheel articulation
• Emergency Maneuvers: Better grip means better avoidance ability

Electric SUVs especially benefit from DiSus by counteracting high center-of-gravity behavior caused by heavy battery packs.

7. A Technology Built to Be Mainstream

What sets DiSus apart is BYD’s philosophy of technology democratization. Instead of limiting advanced suspension systems to top luxury vehicles, BYD is rolling DiSus into:

• Mid-size SUVs (Song L, Sea Lion 05)
• Premium sedans (Han series future versions)
• Flagship brands (Denza and Yangwang)

This ensures millions of users, not just a select few, gain access to intelligent chassis control earlier than the industry standard.

Conclusion: Confidence You Can Feel

Suspension is one of the only components that passengers feel every second of the journey. With DiSus, BYD has engineered that experience into something more:

• Softer when comfort matters
• Firmer when dynamics matter
• Smarter when safety matters

Electric mobility isn’t only about quiet cabins and powerful motors—it is about ensuring every drive feels controlled, composed, and enjoyable. BYD DiSus makes that vision a reality today, paving the way for future intelligent mobility to be not just electrified, but truly refined.
