＂American stop＂ doesn’t even roll over？ Looking up at U7, why is it so stable？

At the Shanghai Auto Show, which opened on April 23, I looked up to the brand to bring all the models to the show. Among them, it was officially listed on March 27 not long ago, with two power forms of pure electricity and plug-in, as well as four-seat and five-seat layouts, with a starting price of 628,000 yuan.

It is worth noting that Wangwang U7 is not only equipped with four-wheel independent torque vector control technology, but also equipped with the world’s first intelligent suspension body control system, Yunqi -Z, and the plug-in version is also equipped with the first domestic horizontally opposed engine.

Thanks to the above hard-core technology, it is hoped that U7 can show excellent passability in daily driving and various difficult working conditions, and its safety is better guaranteed.

Recently, Wangwang U7 also demonstrated a variety of projects in the offline internship in Beijing. Let’s take a look at the ultimate technical strength of U7 from the real performance of the vehicle!

 

The engine, transmission and chassis, the three major parts in the oil truck era, are electrified and intelligent in the new energy era. In terms of body, automobile suspension is a typical example.

Previously, the air suspension mounted on the car was advanced, but the response speed and control accuracy were relatively limited. Today, the development of new energy vehicles gave birth to the evolution of traditional hydraulic shock absorbers into electronic control.

Yunqi -Z is the world’s first suspension motor developed by BYD in full stack, which can directly convert electric energy into kinetic energy, so as to achieve the full link conditional speed of only 5 milliseconds, and the real millisecond response. In addition, the height adjustment accuracy of Yunqi -Z reaches 1 mm, and the peak power of the system reaches 50kW.

This makes it possible to adjust the height with high frequency at the fastest speed of 500mm/s when looking up at U7 in the driving process, such as encountering rocks at the bottom, potholes, or height limiting poles at the top, so as to achieve efficient and accurate obstacle avoidance, prevent vehicle collision and improve the safety of vehicles and drivers and passengers.

Looking up at U7 Elk, the maximum speed can reach 95.78 km/h. Relying on the extreme performance of Easy Square, the vehicle can not only achieve zero acceleration in 2.9s, but also control the torque of each wheel end in real time, stabilize the body posture and ensure driving safety.

In the high-speed lateral rear-end collision (commonly known as American stop) test, the stopped vehicle will hit the rear bumper of the stopped vehicle at high speed. In the United States, the origin of "American stop", the police will use this method to make the pursued vehicle out of control, so as to carry out the next law enforcement.

In the test process of looking up at U7, due to the easy square technology, the change of wheel end torque is accurately identified, and the torque of four wheels is accurately controlled. In addition, Yunxiao -Z instantly presses down to adjust the center of gravity of the car body, increase damping and stiffness to restrain the body roll, so that the vehicle can maintain a stable posture and continue to drive normally without losing control.

Of course, the probability of the so-called "American stop" in real life is still very low, and ordinary people may not be so small as to hit the right side that is most likely to lose balance when they encounter a driving accident. However, it is still a very dangerous thing to encounter a sudden puncture at high speed.

When looking up at U7, there is a flat tire on one side of the wheel, the center of gravity of the car body can also be adjusted by the instantaneous depression of Yunqi -Z+the four-wheel instantaneous perception and the four-wheel torque vector distribution can be completed, so as to help the vehicle return to stable driving at an extremely fast speed, thus ensuring the safety of people on board.

Through the above extreme test scenarios, it is not difficult to see that U7 truly practices the phrase "safety is the greatest luxury", interprets the technological luxury with the ultimate performance experience, and redefines the D-class sedan with a number of industry-leading exclusive technologies.

At present, Hope U7 has arrived at the store one after another, and friends who are interested in this car can experience it in person. Through the road test drive, I think everyone can personally feel the completely different control experience brought by the fully electronically controlled vehicles in the new era.
