ESP: is it a whim or a necessity? Is it necessary to have this system in the car or can you easily do without it? You will learn the answers to these questions from this article.

ESP is a system of electronic stabilization or exchange rate stability. Whoever likes to be called. Different manufacturers may have different names. Twin brothers are DSTC, DSC, VSC, VDC, ESC systems.

ESP. What does this give the driver?

First of all safety in extreme situations. In case of danger, the system takes the initiative and intervenes in control in a matter of fractions of a second. ESP controls the vehicle's lateral dynamics and helps maintain directional stability. In particular, it is able to prevent side slip and skidding, stabilize the trajectory of movement and the position of the machine. This is especially true when driving at high speeds and with poor traction. Of course, nothing in this world is perfect, and no one can guarantee 100% protection. But this smart assistant will help you out more than once in extreme situations.

The principle of its operation is quite simple. It receives data from the ABS sensors and, if necessary, brakes the wheels.

History

Something similar to modernESP was patented in 1959. The German company Daimler-Benz called such an invention a "control device". However, it was only in 1994 that the idea was put into practice. Since 1995, the ESP system has been serially installed on the CL600 coupe, and then on all S and SL cars. Is it a whim or a necessity?

Judging by the fact that today this option is available on almost all car models, it can be judged that the system has proven itself well. But don't buy ESP Japan. Trust the original package.

ESP: What is it and how does it work?

The system is connected to the engine control unit, ARS (traction control) and ABS. ESP continuously processes signals from various sensors. In particular, thanks to the ABS, the system receives data on the speed of rotation of the wheels. The position of the steering wheel and the pressure in the brake system are also taken into account. But the main indicators are the angular velocity sensor, which is calculated relative to the vertical axis, as well as the lateral acceleration sensor. It is these devices that are able to give a signal that a lateral slip has appeared along the vertical axis, determine its degree and give orders for further actions. The system constantly monitors vehicle speed, engine speed, steering angle and skid.

The controller continuously compares the actual behavior of the car on the road with that which is laid down by the program. If deviations are observed, the system perceives this as a dangerous situation and takes action.action to fix it.

To return the car to its previous course, the system can give a command to force the braking of the wheels. This action is performed by the ABS hydraulic modulator, which pressurizes the brake system. At the same time, a command is given to reduce torque and reduce fuel supply.

The system works constantly - when braking, accelerating and even when coasting.
