Creep mode
The word "crawling" is generally used to describe the slow-moving movements of insects, snakes and so on. Applying it to cars means learning the meaning of worms moving slowly. Think about how slow snails are. Crawling mode can be called "low-speed cycle driving assistance system" or simply "fool off-road system", which is usually mounted on off-road vehicles.
When driving on some gravel roads, rain and snow roads, potholes and other roads that are prone to slipping, the wheels of the vehicle are prone to slip or get stuck. When the creep mode is enabled, the driver does not need to operate the throttle and brake, and the vehicle can automatically control the torque output of the engine and distribute the four-wheel braking force according to the road feedback, so as to achieve the effect of smoothly passing through the bad road at low speed. Because it is automatically controlled by the system, it is silly for beginners to cross-country
Crab walking mode
This model is easy to understand. As the name implies, it is to walk like a crab. Of course, crabs walk sideways, so it is also called horizontal mode. At present, there are two main ways for vehicles to walk sideways. First, like the Hummer EV, the front and rear wheels can turn at a large angle at the same time, so that the parallel power output in the same direction can make the vehicle move sideways. Modern IONIQ 5 is more radical, equipped with four-wheel motor, each wheel can turn 90 degrees; Toyota is even more powerful. The new patent allows four wheels to turn 360 degrees at will.
In the second way, if you carefully watch the video of BYD raising its head at the U8 conference, you will find that its wheels are not turning, but the vehicle is moving sideways. In fact, it is mainly achieved by "tires". In the traditional wheel outer ring, there is also a circle of small inclined rollers, which work together to achieve the effects of straight, steering and transverse movement. You have to get a Ph.D. in physics to understand the specific principle, so Brother Wen won't explain it.
This kind of wheel is actually a patent of a Swedish company, called McNamun Wheel, not BYD's. In fact, it is not a rare commodity. Many robots in robot competitions will also wear such wheels.
Floating mode
Speaking of BYD looking up at U8, the video of the conference also showed it walking on the water, just like a crocodile floating on the water. It is not difficult to realize the floating of the car, but it is the sealing of the car that is difficult. As long as the car body doesn't get water, it can float on the water like a boat. But this means that the cooling system and other systems of the vehicle must find another way. As for how BYD solved it, it is unknown. Anyway, the vehicle has a certain buoyancy reserve, and the rest is left to the eddy current generated by the high-speed rotation of the wheels to propel.
Of course, aquada is nothing new. As early as 2003, there was a real aquada called Gibbs Aquada. However, its concept of building a car is still based on the ship, and the body is basically a model of the ship. To prevent water from entering, there is no door. Wheels can be put away and put down like the wheels of an airplane, and it is necessary to rely on propellers to get down to the hydraulic drive form.
Aircraft mode
Walking on the ground and floating on the water, it is impossible to fly without the sky, so there is a flying car. There are also several forms of flying cars, such as the flying car that Geely wants to invest in. To put it bluntly, it is an airplane with foldable wings. In the folded state, the top speed of ground running is 1 10 km. If you want to go to the sky, it takes 40 seconds to spread your wings, and then run 30 meters upwards, and you will go to the sky. The maximum flight mileage 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: the plane, the passenger compartment and the chassis. Chassis+cabin = car, plane+cabin = helicopter. As for the practical significance, it is estimated that there is still a long way to go.
Of course, there are flying cars in Tucki's concept, but since it is a concept, the imagination of pictures and the like is too limited, and the money is persuasive-1. Is it still a car that can fly to sea? Just a car name. Mango also plans to finance the car. You can add a drill bit to the front of the car to drill underground, or the whole water storage tank can dive to the bottom of the sea like a submarine. This is called stealth mode. Is the boss interested in investing?
Generally speaking, with the development of science and technology, cars are not only simple means of transportation, but also incorporate more science and technology, which makes travel easier and more interesting and can meet the travel needs of different scenes. After all, it is a good thing.
