Introduction: For the models of the BYD Han family, I believe everyone is already very familiar, and BYD Han has been optimizing and upgrading around intelligent cockpits, driving experience, and assisted driving in the past three years; This time, the BYD Han family will usher in a new OTA upgrade, one of the highlights of this upgrade is the Yunjian-C intelligent damping body control system, which can make the vehicle more fun to drive, and also better take into account the comfortable experience of driving. Earlier we have done a test drive experience on BYD Han EV(configuration| inquiry), DM-i, DM-P and other models, today is mainly for this upgraded Yunjian-C system to bring the driving experience with you to share, about the exterior and interior part will not be too much detail here, interested students can look at our earlier test drive article.
Yunzhen-C intelligent damping body control system, by controlling the shock absorber solenoid valve to adjust the damping, can realize stepless adaptive adjustment of damping, which can meet the needs of drivers and passengers in different use scenarios. When the vehicle passes over bumpy roads, Yunjian-C adopts a high-frequency and small-damping comfort control strategy to make the chassis "soft", which can effectively buffer the road excitation input and effectively improve comfort; When the vehicle is in rapid cornering, acceleration, braking, the low-frequency and large-damping control strategy is adopted to make the chassis "hard" and provide greater support, thereby improving the handling experience of the vehicle.
2. How does it feel to drive?
The road we test drive today is mainly a mountain road with many curves, and we know that electric vehicles tend to experience more surging in straight-line acceleration, and for curves, how can we really feel the handling of a car? Since this test drive is driving on an open mountain road, considering the road conditions and the existence of social vehicles, the speed is not too high, but there are not many cases of sharp acceleration and sharp deceleration in mountain roads, and when the vehicle accelerates quickly from a stationary or slow speed, you can feel that the vehicle is well suppressed, and when you step on the brakes when entering a corner, the vibration of the vehicle "nodding" is also controlled by the body.
Driving on the road with multiple curves, you can also feel that under the control of Yunzhen-C, the suspension support on the outside of the vehicle becomes stronger, and the vehicle roll is also suppressed well, even if the vehicle is in different speeds or different corners, the feeling of roll is actually very close, it can be seen that this set of predictive ability of Yunzhen-C can adjust the suspension support strength according to real-time vehicle conditions or road conditions.
3. How is the riding experience?
In addition to driving, today when riding, I also feel the ability of the Yunji-C system to control the stability of the vehicle, and when passing through some continuous and fine undulating roads, the vehicle's resolution of vibration is obvious, and it will not affect the riding experience.
When driving on more intense mountain roads, the longitudinal and lateral center of gravity shifts of the occupants in the car are controlled very high, and the rear passengers will not feel dizzy when driving on the curved mountain road. Not only is the driving texture excellent, but the riding experience is also very high-class.
4. What other surprises?
In addition to the Yunjian-C system, this OTA upgrade also upgrades the iTAC intelligent torque control system, profile mode, UWB digital key, mobile phone forget reminder and other functions. Among them, the iTAC intelligent torque control system can improve vehicle dynamics, stability and handling by intelligently adjusting the driving torque.
iTAC can quickly identify the trend of the vehicle's operating status through a unique control architecture and algorithm according to the motor state, body attitude and wheel state, and intelligently allocate the driving torque of the front and rear axles to improve the dynamics, stability and handling of the vehicle. For example, during today's test drive, there was a sudden rainstorm, and iTAC can quickly adjust the driving torque of the front and rear axles when the wheels have a precursor to skidding, so as to ensure the stable play of the torque of the whole vehicle, so that the vehicle can obtain sufficient traction and prevent the occurrence of skidding. And in today's sudden rainstorm, the control of the vehicle in terms of stability is indeed felt.
Summary:Through today's test drive, you can feel the improvement of the vehicle in terms of driving control, comfort and driving quality, especially in the process of today's test drive on the mountain road, although the vehicle's acceleration ability is very strong, the overall driving feeling of the vehicle in the mountain road does not give people an abrupt feeling, but this experience that takes into account the fun and comfort of driving makes BYD Han have more driving experience, and we are more looking forward to the vehicle's future market performance.
