Looking forward to the U8 real car debut with Yunnian -P body control system.

On April 10th, I looked forward to the appearance of the U8 real car. As the first mass-produced model launched by BYD’s high-end brand, we look forward to U8 positioning a million-level new energy hard-core off-road, equipped with "Easy Sifang" power system, and providing four wheels and four motors. It is also equipped with BYD Yunqi -P intelligent hydraulic body control system released today. It is reported that Wangwang U8 is expected to go on sale in August.

Looking up at U8, there is a huge I-shaped grille on the front face, and there are also dot matrix LED light sources on both sides. The car body will also have an electric hidden door handle, and the shape of the rear is very tough. The external spare tire is located in the center, and the rear has "L" and dot matrix LED light sources, which have strong recognition. The top of the new car is equipped with lidar to provide high-level autonomous driving technology.

Previously, the official data showed that the length, width and height of U8 were 5319*2050*1930mm, and the wheelbase was 3050mm. It is expected that the car will also have excellent space performance. Polygonal wheel arch integrates hardware such as laser radar, camera and side sign lamp, and its modeling design is practical.

In terms of interior, the new car adopts a four-spoke flat-bottomed steering wheel, which is more in line with the hard-core temperament of the vehicle. In addition, the size and clarity of the all-LCD instrument panel have a good performance, and it will adopt a joint screen design. In terms of seat layout, the vehicle will adopt a 7-seat layout form of 2+2+3.

In terms of power, the new car is equipped with the "Easy Sifang" power system, which provides four wheels and four motors. The maximum power of a single motor of the vehicle is 220-240kW, and the maximum torque is 320-420 N m, with the fastest 3-second acceleration performance. In addition, it is also equipped with a square blade battery and a non-loaded body.

"Easy Sifang" is a set of power system with four-motor independent drive as the core, which has been completely reconstructed around the characteristics of new energy vehicles from three dimensions: perception, decision-making and execution, completely subverting the power system capability system of previous fuel vehicles. It can realize accurate control of vehicle four-wheel dynamics by means of four-motor independent vector control technology.

The body stability control of traditional fuel vehicles is limited by its era and technical development, and the speed and accuracy of perception are far from the ultimate safety. There are some problems in the implementation level, such as slow response, low efficiency, low power and low degree of four-wheel differentiation. Compared with the traditional fuel vehicle power system, the "Easy Sifang" technology can independently adjust the dynamics of the four-wheel end of the vehicle at millisecond speed through a more perceptive electric drive system, thus better controlling the body posture.

Thanks to the above technical achievements, the "Easy Quartet" technology can provide users with greater safety redundancy. For example, after a single wheel of a vehicle has a flat tire, the torque of the remaining three wheels can be accurately adjusted at a frequency of 1,000 times per second, and the body posture can be compensated and intervened by the driving wheel in time to help the driver stop the vehicle stably and controllably. This function is expected to avoid the occurrence of secondary accidents to the greatest extent from the root of power.

With the "Easy Sifang" technology, the vehicle core system protection ability reaches IP68 level, and the vehicle body and cockpit are well sealed, so it can even obtain the emergency floating ability by virtue of the four-wheel independent vector control function.

In addition to the ultimate security, "Easy Sifang" will also provide users with the ultimate performance and experience. The "Easy Sifang" platform has a maximum rotation speed of 20500rpm and a vehicle horsepower of over 1,100 horsepower, which can meet the performance requirements of various extreme scenes such as streets, off-road and racetracks. The powerful power brought by independent research and development of highly integrated motors also supports the "Easy Sifang" technology to realize flexible in-situ U-turn function on high adhesion roads such as asphalt roads.

With the independent positive and negative torque output capability of the four-motor drive technology, the "Easy Square" platform can even achieve a braking distance of less than 40 meters and an agile steering capability of less than 12 meters when the steering gear and brakes are not working, so that large SUVs also have the flexibility of not losing A0-class cars.
