But many drivers still have doubts about the actions of the computer, as if nearby - a driving school instructor pushing the pedals. The reason is clear: the systems of the first generations were far from perfect and an experienced driver in a real traffic situation often replayed the programmer.

Therefore, when TRW, one of the leading developers in this field, proposed to test its latest systems at the winter training ground, I was in a critical mood: to torture - so to torture! And here I am in Lapland, near the Arctic Circle. The Swedish town of Arvidsjaur is famous not only for skiing and winter fishing, but also for a huge training ground on a frozen lake. In addition to two circles with a diameter of 200 and 500 m with ice and snow paths, there is a site with deep snow and wide strips of rolled snow and polished ice to carry out the "rearrangement". A little further away, on the earth’s firmament, there are strips of ice and heated asphalt for testing ABS (parallel, as well as alternating in a checkerboard pattern and in random order), a hangar with a fifteen percent slope of ice / asphalt, where they are experiencing hill starting assistance systems, and a race track.

TORQUE

Let's start with stabilization systems. Subject "Peugeot 407" - not quite a standard car. On a production copy, the ESP automatically turns on at a speed of 50 km / h (this is the manufacturer's requirement), here you can also check the behavior of the car without electronics at any speed. We leave on a small ice circle. The speed with the involved ESP reached 70 km / h. The car drags slightly, but it does not leave the trajectory and does not “shut up”, maintaining a stable speed. We turn off the ESP - already at 55 km / h the drift begins, but with the help of a steering wheel and gas it is possible to bring the stable speed to the same 70 km / h. The Peugeot 407 has a distinct oversteer, so he doesn’t like gas discharge, but the engineers did a great job - it’s a pleasure to drive it. On the outer snow circle, the speed with the electronics turned off was able to increase to 85 km / h, but ESP here refused to accelerate the car faster than 50 km / h, although it behaved quite docilely! A similar picture is on a large circle, only the speed here has exceeded one hundred. “Snow and ice require different management programs,” the TRW engineer explained to me, “but it is very difficult to determine the type of coverage by indirect signs. The main thing for us is to avoid unpredictable situations, but if the driver can drive faster, please!”

The next car, the Opel Vectra C, showed equally excellent handling with neutral understeer. ESP works just perfectly (unlike first-generation systems, it brakes not one but three wheels), leaving the driver the opportunity to adjust the trajectory of the wheel. The speeds here were even slightly higher than on the Peugeot, and in the snow I was unable to overtake the computer.

But the third “experimental” - “Volkswagen Golf” strove to jump out, both with the ESP turned on and off. It’s good that there was a real, and not an electric handbrake on hand - only he helped to return the car to the trajectory. A familiar picture! Nevertheless, the role of the chassis settings cannot be underestimated: electronics can’t completely “break” the character of a car. Although without it - even worse. At maximum speed, the percentage of ideal hits in the trajectory is low, and with ESP - although the departure, but small.

CLIMBING HILL

The Hill Assist system has already become a serial system, including on low-cost mini cars, which are usually equipped with a manual transmission in Europe. Test "Lancia-Epsilon" - just one of them. Having released the brake pedal on the rise, I have three seconds to start moving - while the ESP unit holds the pressure in the system. For everyday driving is enough. For vehicles of a higher class, TRW offers a more advanced option - “fleet” (Auto-P). The electro-hydraulic system (where the pressure in the system can be created by a separate pump) holds the brake for up to 3 minutes, and then automatically puts the car “on the electric handbrake” - such as, for example, on the Audi A6 (with a compact planetary gear). A similar mechanism is also used as a service brake - while on prototypes.
