What is Yaw? In which situations can you help us?

All cars have something in common. Automotive Science. This sector structures its profession in technical knowledge about the operation of a car. A sub-branch of automotive science is physics, where there are very important attributes: pitch, swings Yes yaw. The latter is the one we are dealing with, which we can first define as the accidental or involuntary deviation of the vehicle from its natural course.

Yaw occurs when the weight of a vehicle shifts from the center of gravity to the left or right. This is a change that the driver will feel when sitting in their car. For example, if you suddenly drive, brake and accelerate, the car will move around its horizontal transverse axis (pitch). This causes the vehicle to rotate around its center of gravity. Yaw performs during turns. Anything that makes your car revolve around its center of gravity is a deviation from its trajectory.

What is Yaw?

Cross a pole from the top of a vehicle. The clockwise or counterclockwise movement of the pole and the car is called yaw. Another definition of yaw is, well, spin. Here the vulture is nothing more than a value. It has no power on a vehicle. However, it is very important for calculations. When a car turns, the wheels turn at different speeds. For example, those on the right turn faster than those on the left as the vehicle turns to the left.

A moving vehicle is by definition sand lean in curves because it points in a different direction than the direction it moves at any point in it. This is because the wheels further from the inside of a curve take up more area than the wheels closer to the inside line. This creates an unbalanced force, which causes a vehicle to rotate. Everything happens at the speed of differential boxes, but that’s another story. That axial movement is the yaw, which means the car is moving in a different direction than it is pointing.

Yaw is important because air hits the car differently when it is at an angle to oncoming air compared to when it hits the air head-on. Therefore, place the vehicle in a position where the air helps it to turn slightly. Because the yaw can be caused by a different value in centrifugal forces applied to the front and rear wheels, or also by a difference in adherence in the same.

In the vast majority of cars, the rear axle describes a smaller radius than the frontTherefore, the centrifugal force in the latter will be greater than in the former, as long as we assume that the weight balance on all wheels is equal. Starting from the principle that the centrifugal force is inversely proportional to the radius of the bend and directly proportional to the weight carried by the axles, the center of the car moves forward so that the additional load on the front axle exceeds the value of the axles centrifugal forces.

Basically, if we want to make the car change direction, it is necessary to produce a certain yaw. If we take a turn with a certain turning circle and the yaw is not sufficient in relation to the speed of the vehicle in the turn, then the known understeer. If, on the other hand, the vulture is excessive, the so-called upset. Therefore, depending on where the vehicle’s traction is or the different force applied when braking, the vehicle will yaw, slip into a slip (lake or donkey).

What is Vulture Control?

Similar to the differential lock, which controls the distribution of torque to the driving wheels, yaw control helps reduce vehicle understeer and oversteer and provides faster turning power. And the system that cars have to control that yaw and raise or lower it so that it stays on the path the wheels mark is what we commonly know as stability control (ESP).

If the yaw control is set too high, there is even a risk that too much slip will occur and tire wear will increase significantly. Even if, when it is in the right place, the turning ability of the car is very prominent. The yaw control setting is an important compromise depending on the layout design to be tackled, although this is already in a professional setting. In road cars, the calibration of the system and suspension is done, knowing what the safest reactions should be at all times.
