Introduction of working principle of FSD system

BYD has independently developed the FSD variable damping suspension system, which is used for the configuration of vehicles equipped with Han models. FSD shock absorber is based on the design scheme of shock absorber and integrates additional frequency response valve system. According to the dynamic situation of the vehicle, different damping characteristics can be realized in suspension control and body control, providing the best comfort and stability scheme.

The FSD valve is used to control the oil flow in the damping cylinder, so as to automatically adjust its own hardness. When a vehicle passes through a bumpy road with high vibration frequency, the FSD valve opens two channels for oil flow to pass through, so that oil can pass through more easily, the damping force of the shock absorber is reduced, and the shock absorber becomes "soft", and the shock absorber plays the role of absorbing road impact, so that people in the vehicle have a comfortable driving experience. When the road conditions are good, the vibration frequency of the shock absorber is low, and the FSD valve in the shock absorber cylinder only opens one channel for the oil liquid to pass through. At this time, the damping force of the shock absorber is large, which makes the car more stable and more maneuverable when driving.

The FSD shock absorber equipped on the Han model can perfectly adapt to various road conditions such as low-lying, high-low and gravel roads by automatically adjusting the damping force and rebound speed, effectively filtering the bumpy feeling caused by different roads, and keeping the car body stable and comfortable for drivers and passengers, at the same time, it can also retain appropriate road feedback and improve the driving pleasure of the vehicle.

The Han family sold 31,786 vehicles in November, exceeding 30,000 vehicles for three consecutive months, and the cumulative sales exceeded 400,000 vehicles. As a mid-to-high-end self-owned brand, Han has been continuously sought after by consumers since its listing. Since the launch of a brand-new upgraded model in March, with the support of DM-i super hybrid and DM-p hybrid technology, the sales volume of Han family has continued to grow, with the cumulative sales exceeding 400,000.
