This article will help you distinguish the BYD Yunniang suspension system

The technologies that BYD has incorporated into their mass-produced cars, such as the DM-i super hybrid, e-platform 3.0, blade battery, and Yunniang chassis control system, are becoming increasingly familiar. The first three are relatively straightforward to understand based on their names, but many car enthusiasts are still puzzled by the Yunniang system. This confusion is partly due to the complexity of chassis technology and partly because the system is divided into several variants: Yunniang-C, Yunniang-A, Yunniang-P, Yunniang-X, and Yunniang-Z, which makes consumers wonder which one is the best. In this article, I will provide a detailed explanation to help clarify these different systems.
 

Technical Features of Yunniang C

The full name of Yunniang C is the Intelligent Damping Body Control System. This system is currently installed on models such as the BYD Song L, BYD Han, BYD Tang, and Denza D9.

Working Principle: Yunniang C adjusts the strength of the active suspension damping by controlling the solenoid valve of the shock absorber. This allows the system to modify the hardness of the chassis system according to changes in the road surface.
 

Performance:

• Paved Roads: Yunniang C provides a stable driving experience.
• Mountain Roads: It ensures lateral support by increasing the hardness of the suspension damping.
• Unpaved Roads, Speed Bumps, and Uneven Roads: The suspension damping is softened to improve comfort.

Summary: Yunniang C strikes a balance between control and comfort but leans more towards comfort, making it suitable for consumers who prioritize a comfortable driving experience.
 

 

Technical Features of Yunniang A

Yunniang-A’s intelligent air body control system is currently featured in the Denza N7, a mid-to-high-end model under BYD Auto. Yunniang A incorporates two core technologies: iCCT (intelligent Comfort Control Technology) and iCVC (intelligent Vector Control Technology).

1. iCCT (Intelligent Comfort Control Technology):

   • Function: This technology suppresses the head-raising or nodding phenomenon during acceleration and deceleration, maintaining the vehicle’s front and rear balance to ensure a smooth and comfortable ride.

2. iCVC (Intelligent Vector Control Technology):

   • Function: This integrates the suspension, braking, and drive systems to enhance road performance. It significantly improves cornering performance and provides high controllability, particularly beneficial for mountain driving.

Comparison to Yunniang C:

• Focus: While Yunniang C is designed with a balance between control and comfort, Yunniang A emphasizes greater controllability and sportiness. It is a feature of BYD's high-end series models and is ideal for consumers who prioritize driving quality.

 

Technical Features of Yunniang P

The full name of Yunniang P is the Intelligent Hydraulic Body Control System. It is currently installed in the Yangwang U8 and BYD Leopard 5. Yunniang P is specifically designed for off-road vehicles, and one of its core features is the long-stroke lifting function. For example, the Yangwang U8’s suspension can achieve a lifting stroke of up to 150 mm in off-road conditions.
 

Key Features:

• Individual Wheel Adjustment: Yunniang P allows for independent adjustment of each wheel's height. When the vehicle is parked on uneven terrain, the system can balance the body horizontally, a feature referred to as "camping mode."

• Enhanced Off-Road Capability: On rugged cross-axle roads, Yunniang P can adjust the ground clearance of each wheel individually. This improves the vehicle's passability and escape ability, enhancing its off-road performance and limit.

Summary: Yunniang P is tailored for off-road conditions, offering significant advantages in terrain adaptability and vehicle stability. Its advanced hydraulic control system ensures superior performance in challenging environments.
 

 

Technical Features of Yunniang X

The Yangwang U9, equipped with Yunniang X technology, showcases full active body control capabilities. This technology achieves "0" roll, "0" pitch, three-wheel driving, vehicle dancing, and in-situ jumping, representing the highest level of global body control systems. BYD has once again pioneered the industry, leading the development of body control technology.

Features of Yunniang X:

1. Fully Active Suspension: Yunniang X employs a fully active suspension system driven by motors, enabling precise vertical control of the vehicle.

2. High Response Speed: The system allows for rapid adjustments in vehicle height and suspension stiffness, including the capability for the vehicle to perform "jumps."

3. Intelligent Perception: Yunniang X utilizes ADAS sensor data to perceive road conditions in real time, making predictions and adjustments accordingly.
    

While specific technical details of Yunniang X have not been fully disclosed, its demonstrated performance has generated high expectations for future mass-produced models.
 

 

Features of Yunniang Z

When driving, the tires make contact with the ground, and the suspension is crucial for connecting the tires to the vehicle's body. To handle impacts from various directions, the suspension must manage stress along the X, Y, and Z axes. Traditional suspensions use shock absorbers and springs—whether air springs, electromagnetic suspensions, or coil springs—to buffer along the Z axis, reducing road vibrations.
 

With the advent of electrification, suspension design now offers more possibilities. Suspensions can be controlled by 48V voltage, leading to innovations such as disconnectable 48V anti-roll bars. BYD's Yunniang Z advances this by using higher voltage and replacing traditional shock absorbers with motors. This setup offers superior adjustment speed and accuracy.

Key Features of Yunniang Z:

1. Motor-Driven Suspension: Replaces traditional shock absorbers with motors, eliminating the oil buffer and resulting in reduced energy loss and faster response speeds. Adjustments can be completed within 10 milliseconds, allowing for up to 100 automatic adjustments per second. This speed is more than 10 times faster than traditional adaptive suspension systems.

2. Enhanced Flexibility: The rapid adjustment capability significantly improves vehicle handling at high speeds, making the vehicle more agile.

Impact on Driving Experience:

A small step in body control translates to a significant improvement in travel comfort. The Yunniang intelligent body control system combines extreme performance with safety, offering a transformative upgrade to the driving experience. With its advanced technology, high intelligence, safety features, stable driving, and comprehensive coverage, the Yunniang system will be integrated into Dynasty, Ocean flagship models, Tengshi, Yangwang, and other professional personalized brands. This integration will elevate BYD's entire brand and redefine luxury car standards in the new energy era.
