We are used to a very simple model of interaction with a car, when clear actions on our part should lead to the same adequate reaction of the “iron horse”. But life is much more diverse and can bring unexpected surprises. This happens especially often in winter. Why? Yes, because at this time of year, smart active safety assistants are in the most defenseless position. After all, they can influence the situation only with the help of wheels that are in contact with the road. And the adhesion coefficient can be so low that their positive contribution to solving the problem is negligible.
However, a person is able to constantly control the situation, analyze the behavior of the car and make the necessary adjustments to its actions. Let’s imagine a simple situation. We are approaching a gentle and therefore fast bend to the right. Ice on the road. We turn the steering wheel to the right, waiting for an adequate response from the car. But he does not come: for some reason the “swallow” does not obey. Stabilization diligently tries to do something, the brakes actively try to slow down, and the torque redistribution system tries to influence handling and still start the car on the required trajectory. But as we said, on ice and at high speed, she’s not going to succeed. Moreover: the car turns into a brick that slides limply to the outer curb.
But stones can also be controlled! This requires intelligence and an understanding of the physics of the process when a car enters a corner. The car only went straight because the combination of speed and steering angle conflicted with the low coefficient of friction. The tires cannot maintain contact with the road and the trajectory of the car. All is lost? No! If, when you turned the steering wheel to the right, the car went straight ahead, then turning the steering wheel to the left may have some effect in this situation. Let’s try.
As the steering wheel returns to the “straight” position, the car’s behavior begins to change: it will try to take the correct turn again. And not only due to the fact that the front wheels restore contact with the surface, because reducing their angle of rotation reduces the load on the contact patch. Something else will happen.
At the moment when the front tires “hook”, the rear ones, which were previously in relatively reliable contact with the road, will suddenly switch to skidding and, under the influence of centrifugal force, will begin to shift the rear axle of the car to the left, causing the vehicle to turns even more actively. And this will happen even against the background of the operation of the state-of-the-art stabilization system. Which in impotent rage will squeal with brakes and active differentials, because at that moment the car went into a paradoxical extra-control mode.
And the movement of the steering wheel to the left, that is, in the direction of reducing the angle of rotation of the front wheels, will lead to an increasingly active turn of the car to the right. And although this phenomenon also occurs on summer paving, it manifests itself most clearly in winter, which professionals shamelessly take advantage of. But the described mode also has a “dark” side. Such an unusual response can cause the machine to over-torque, which the pilot may not be ready for. In short, do not enter a corner at a speed that requires the driver to use complex driving techniques.
