Shulou(Shulou.com)11/24 Report--

CTOnews.com November 16 news, looking up to the auto official announced that the supercar platform will be released at the Guangzhou Auto Show, which will open on November 17, and the Yi Sifang concept car will also be unveiled at that time. Today, many bloggers have released an experience video of looking up at the Yi Sifang concept car, which has no steering column and brake calipers, but does not rely on pure mechanical structure to realize steering and braking.

The video shows that BYD looks up at the easy Sifang concept car similar to the U8, but the whole body uses a hollowed-out design, and the car is covered with anti-rolling frames, which is full of cyber beauty.

The biggest highlight of this car is its drive and control system, which is based on BYD's easy Sifang platform and uses four-wheeled independent motors, which can achieve some functions that traditional fuel vehicles cannot do.

The video from @ independent brand is the hope of the country, according to blogger @ Skywalker _ automotive engineer, the traditional steering relies on the steering wheel and the physical steering column behind, and the gear of the steering bar transmits the steering angle. then rely on the differential to distribute the speed difference and torque between the left and right wheels to achieve smooth steering. The easy square technology is different. According to the driver's steering intention, it calculates the required steering angle, and the computer distributes the torque of the front wheels on the left and right sides to deflect the steering rod and realize the wheel steering.

The traditional braking is by stepping on the brake and the torque is transmitted to the hydraulic cylinder to push the friction disc to clamp the brake disc to generate friction torque to achieve braking. The braking force is related to the foot depth and the force. On the other hand, Yi Sifang generates electromagnetic resistance torque by controlling four driving motors to generate electromagnetic resistance, which is a bit like single pedal mode. Officials say it can produce a maximum brake deceleration of 1.0g, and the braking distance with an initial speed of 60km/h can reach a minimum of 20 meters.

In January this year, BYD released a new high-end car brand look up and its core technology "Yi Sifang". "Yi Sifang" is China's first mass production of four-motor drive technology, is a set of four-motor independent drive as the core power system, from the perception, decision-making, implementation of the three dimensions around the characteristics of new energy vehicles to carry out a comprehensive restructuring, subverting the previous fuel vehicle powertrain capability system. Through the independent vector control of four motors, the vehicle trajectory is controlled to realize the functions of U-turn, agile steering and emergency floating water.

BYD is expected to release more information about the car tomorrow, when CTOnews.com will bring the latest report.
