The car's driving mode is bionic, and the water surface that crawls on the ground and floats is ruined.

The automotive industry loves small animals. For example, Ford likes rabbits, Jaguar likes tigers, Peugeot and Roewe like lions, Dodge likes sheep, Porsche likes cows, Ferrari likes horses, and pigs The north... Well, in fact, in addition to the car logo, some driving modes of the car are also learned from animals, so now the car is not just as simple as driving forward and backward.

Creep mode

The word "creep" is generally used to describe the slow movement of insects, snakes and the like. Applying it to cars is to learn the meaning of insects traveling slowly. Just think about how slow a snail is. The full name of creep mode can be called "low-speed cycle driving assistance system", or simply and crudely called "fool's off-road system", which is generally installed on off-road vehicles.

When driving on some slippery roads such as gravel roads, rain and snow roads, pothole roads, etc., the vehicle is prone to wheel slippage or pitting. Enabling creep mode eliminates the need for the driver to operate the accelerator and brakes. The vehicle can automatically control the engine's torque output and allocate four-wheel braking force based on road condition feedback to achieve the effect of smoothly passing through poor road surfaces at slow speeds. Since it is automatically controlled by the system, this is quite annoying for novice off-roaders.

Crab walking mode

This mode is easy to understand. As the name suggests, it walks like a crab. Of course, crabs walk sideways, so it is also called sideways mode. Currently, there are two main ways to allow vehicles to move sideways. First, like the Hummer EV, the front and rear wheels can turn at a large angle at the same time, so that parallel power output in the same direction allows the vehicle to move laterally. Hyundai IONIQ 5 is more radical, equipped with four-wheel motors, and each wheel can turn 90 degrees; Toyota is even more powerful, with a new patent that allows the four wheels to turn 360 degrees at will.

The second way, if you watch BYD’s U8 launch video carefully, you will find that its wheels did not turn, but the vehicle moved laterally. In fact, it is mainly achieved by "tires". On the outer ring of the traditional wheel, there is also a circle of small rollers arranged obliquely. These oblique rollers work together to achieve the effects of going straight, turning, and traveling horizontally. You have to get a Ph.D. in physics to understand the specific principles, but Brother Man won't explain it.

This kind of wheel is actually patented by a Swedish company called Mecanum Wheel, not BYD. In fact, it is not a rare item. Many robots in robot competitions are also equipped with such wheels.

Floating mode

Speaking of BYD looking up to the U8, the conference video also showed a scene of it walking on the water, like a crocodile floating on the water. It is not difficult to make a car float. What is difficult is the sealing of the vehicle. As long as water does not enter the car body, it can float on the water like a boat. But this means that the vehicle's cooling and other systems have to find another way. It is unknown how BYD solved the problem. Anyway, the vehicle has a certain buoyancy reserve, and the rest is left to the vortex generated by the high-speed rotation of the wheels to propel it.

Of course, amphibious cars are not a new thing. As early as 2003, there was a real amphibious car called Gibbs Aquada. However, its building concept is still based on boats. The body of the car is basically a model of a boat. In order to prevent water from entering, there are no doors. The wheels can be folded and put down like the wheels of an airplane, and even water-driven ones also rely on propellers.

Flight mode

Walking on the ground and floating on the water are indispensable, and flying in the sky is indispensable, so there are flying cars. There are also several forms of realization of flying cars. For example, the flying car that Geely wants to invest in is, to put it bluntly, just an airplane with foldable wings. In the folded state, the top speed on the ground is 110 kilometers per hour. If you want to go to the sky, it takes 40 seconds for the wings to unfold, and then a 30-meter run-up to go to the sky. The maximum flight range is about 800 kilometers.

There are also split structures, such as the flying car released by Beijing Institute of Technology, which consists of three parts: aircraft, passenger cabin, and chassis. Chassis + passenger cabin = car, aircraft + passenger cabin = helicopter. . As for practical significance, it is estimated that there is still a long way to go.

Of course, there is also the flying car in Xiaopeng’s concept, but since it is a concept, the imagination like the picture is too limited, and the persuasiveness of making money is -1. Speaking of which, is this kind of thing that can go into the sea and fly into the sky still a car? It's just a name for a car. Brother Man also plans to raise funds to build a car. A drill bit can be added to the front of the car to drill into the ground, or the entire water storage tank can dive to the bottom of the sea like a submarine. This is called stealth mode. Are the bosses interested in investing?

In general, with the development of science and technology, cars are no longer just pure means of transportation. By incorporating more technologies, they make travel easier and more interesting, and can cope with different scenarios. The demand for travel is a good thing after all.
