CTOnews.com March 21 news, BYD's high-end brand look up to auto officials today answered questions that netizens are concerned about, including the principle of turning around in place, looking up to whether U8 can sail or not.

When it comes to looking up at the U8 how to make a U-turn in place, looking up at the car says that the most direct and effective way to make a U-turn is to turn the wheels on the left and right sides in the opposite direction. This requires the vehicle to have the ability to control the four-wheel torque independently, so that the wheels can rotate both forward and reverse, and that the torque and power of the wheels are large enough to allow the wheels to break through the ground adhesion limit. Yi Sifang's four-wheel independent control and super power naturally have this ability. At the same time, in order to make the U-turn in place can be used in more road conditions, Yi Sifang provides precise torque control, allowing the vehicle to customize the steering angle and speed, which broadens the use of the U-turn function of U8.

In addition, looking up at the car official said that ordinary tires can also achieve a U-turn in place, and the realization of the U-turn function is not directly related to the tire model. Because Yi Sifang can independently adjust the power of the four wheels through the perception of the rotation state of the wheels, so as to ensure the normal operation of the U-turn function in place, and its power is enough to break through the ultimate grip of the vast majority of civil car tires. so as to ensure that under a variety of road conditions, carrying any civil tires can make a U-turn in place.

In view of the tire wear problem when making a U-turn in place, car officials say Yi Sifang has millisecond road condition perception and the ability to accurately control torque output. When making a U-turn in place, Yi Sifang can quickly sense the road adhesion and tire grip, and accurately calculate the minimum torque requirement to make the vehicle turn in place, thus in sand, snow, asphalt and concrete roads. can make the vehicle turn in place on the basis of minimizing tire wear.

"Yi Sifang" technology is the first mass-produced four-motor drive technology in China, which can realize accurate control of vehicle four-wheel dynamics by virtue of four-motor independent vector control technology. CTOnews.com has reported that the highest speed of the "Yi Sifang" platform is 20500rpm, with a total horsepower of more than 1100 horses.

It is worth mentioning that looking up at the car talked about whether U8 can sail as a ship, saying that looking up to develop the emergency floating function is to achieve emergency relief, including wild wading and urban waterlogging disasters. This is a passive safety function similar to an "airbag" rather than an active "entertainment" function. Although U8 has the ability to float for a short time, the car that can "paddle" is essentially a car, not a boat. No user is encouraged to try this feature in non-emergency situations.
