Unter- und Übersteuern: Unterschied? - Bloch erklärt #10 | auto motor und sport

For us car fans, yes, something like that again, Johann Wolfgang von Goethe in the car world, no one has given us

lovers sayings about our favorite toy like the tall Bavarian and one of his most famous sayings. famous is: "If you climb the tree." First you will understeer. If you hear the tree, then you have oversteered and I will not now participate in the discussion about whether the saying perhaps did not first come from rally professor Rauno Aaltonen, but we will clarify the question. what this understeer and oversteer actually is to clarify if my little help vehicle called Meet is from a German startup or a prototype and it has a special feature and that is that I can use it to represent dynamic driving situations to scale that on my phone cell I have the driving dynamics simulation and the car does exactly the same and now we will start with the understeer of an important driving dynamic situation, there is a curve here and I really want to follow this curve exactly with my car because now you will be I have my car here and there the following happens, push out like this He on the radius here while the front wheels follow the original radius more or even a little more extreme that means German engineer I have a greater lean angle in front than behind Understeer What does the driver from the one sitting behind the wheel?

He wants to drive in a certain radius. He should be

matic, but he does not push out and does not have. the feeling that I can drive the radio so under control how it all looks we will show it now with the car and the simulation and then I will give some gas here with a cell phone The handlebars are tight and tight, which is why not It meets my steering specifications, but the tip is significantly larger than what I wanted, it pushes outwards and so I have to transfer a certain total force and he has to decide whether he now drives in a straight line or builds up the force on the sides and the faster he learns, the less force can be built up on the sides or the other way around, Benny drives very fast and still prepares to turn.

Haye is no longer my story. I keep driving straight. or a very large radius, no matter how you turn the tires. Now the normal driver has two options: either he goes off the grass, which means the car is in front, I have a little more pressure on the front wheels and maybe I can drive. In a tight corner I let my steering angle be slightly so the tire no longer has to transmit as much lateral force. We go to the garden and then turn left harder because these two reactions are relatively natural and every driver can do it.

Consequently, understeer is a fairly safe driving dynamic situation and finding solid ground again feels like a Japanese Italian having rear-wheel drive car trauma. There is such a shift that it tends to oversteer the car. He is not a development engineer in the world. Cars with oversteer go into series production, but they all have understeer. It is also not tested with excess power or with a truck, each car is transversal, but it is driven in a circle, defames the researchers faster and faster and we prefer not to suddenly increase the speed, you will feel how the car starts above the front wheels and pushes it up, even in a rear-wheel drive car, I still have our steering towards the king of oversteer, so looking at it.

For example, I can even drive it to oversteer, but that has nothing to do with understeer or fundamental oversteer. You're doing well, I think everyone agreed on that. I agree that oversteer is much cooler and more spectacular than understeer. And by the way, I can also cause oversteer in a front-wheel drive car, for example with a sudden change in load so that the car goes away at the same time. In theory, that's what we need to get the car back on track and I promise. now let's get to the point visually what is it called, but first a little music or driving physics, we will put the car in a layout here, which happens because the rear wheels have a larger radius than the front wheels, the German engineer scares at an angle .

The rear wheels are bigger than the front ones, you can imagine that now we are starting to overtake. Why can the rear wheels only decide between driving straight or traveling sideways at their limit and when they completely overtake the rear wheels? It will break like this and the front wheels will go forward and now we start skidding. If I can maintain this separation with the accelerator pedal, the pro also says to turn with the accelerator and I can only do it with a rear. Wheel Drive Vehicle The more I gas, the more I turn, the less I turn and my car breaks down.

That, of course, puts me in a better mood and now we'll see that with the car. It only affects three. It requires a lot of skills if you don't have them. So at some point you will be lying in a ditch with a beautiful coastline or you will have cut down one tree after another, which means you can. On the one hand, you have to adjust the steering and co

unter

steering accordingly and you also have to adjust your foot on the accelerator. The cars are finite and too slow, all this together is hardly possible for an inexperienced driver and that is why the cars never adjust.

Through the factory controls, by the way, the optimal thing is neutrality, which is the fastest way to move, unless you want to take a sharp turn, then you can look at the long handbrake to fly the project, but then we'll do it. return to walter braun
