Theme Winter driving is always in demand, let alone in February alone. Given the constant changes of temperature in our time with you this question becomes more urgent. Of course, some theoretical knowledge is not enough, but nonetheless, the practice will be easier when you know what to expect from snow or ice-crusted roads. In extreme cold the ice is less podtaivaya under the tread, "holds" the bus is better. That's the film of moisture causes the slipperiness of ice. The same bus is better "holds" the rough ice, worse - a smooth, even worse - a lumpy, like cobblestone pavement. And what about the tires themselves? Dangerous delusion of some motorists is like a tire with a large "off-road" tread (including a special winter) is good on the ice. On slippery surfaces better tires melkoraschlenennym saturated tread. On pure ice tread depth does not matter: if blocked at least the front wheels, the car is out of control! Tire adhesion coating reaches a maximum at the transition from rolling to sliding. This is true for ice. Al, "playing" brakes, manages to keep the wheels just on the verge of Hughes, seeking the most effective braking. Wheel, skid-reaching, uncontrollably. Intermittent braking, when the moment is weakened the pressure on the pedal more efficiently, the wheels begin to roll properly - the car is returned control. By the way, if intermittent inhibition demonstrates the wizard, then moving behind him, you can not notice this - his brake lights are lit continuously. Car registration in recent years are increasingly equipped with antilock brake system (ABS). It operates as follows: if in the process of braking any wheel becomes blocked, the sensor will immediately note the change of its angular velocity. The computer issues a command to disinhibited wheel to prevent further blockage. Sometimes this occurs at a rate of 10,115 times per second, the brake pedal is "shaking" under foot. As a result, the ABS allows the driver to maintain control over the car. And yet, this system should not be overestimated, since the efficiency of inhibition depends not so much from her, but on the coefficient of friction. So do not neglect the tires for the season. Some experienced drivers will disable the ABS, more appropriate for beginners. This is not recommended: experience might bring. You can slow down the engine, without turning off the ignition and transmission. Motor brake is recommended in the following sequence: reset the fuel supply without turning off the clutch, squeeze the clutch, to include a lower gear and re-enable the clutch. The car will increase the momentum and will gradually slow down the speed. It is possible to smoothly podtormozit braking system. This total inhibition very effectively creates a no less braking force than the pads. Four wheel vehicle deceleration that is achieved in both ways, almost equally. Moreover, if we apply them at the same time - slowing down will remain the same. After all, it is actually given by the properties of ice and tires - and nothing more. On the ice, preference is given to engine braking, because blocked (nekatyascheesya) wheel on the ice uncontrollably. Rolling - even in partial slip - provides a minimum of handling, the car obeys steering ... How effective can maneuver on the ice, if all the traction wheels only spend on it? In other words, turn the steering wheel at a constant speed of the car, do not overclock and do not slow down. Try an ice platform to make the experience. At the same speed, for example, 20 mph, turn the wheel at a certain angle, but with a different tempo. If this is done slowly, the car should be behind the wheel, steer. If you turn the wheel quickly, the car will move in the same direction, because the tire contact with the road is frustrating to slip. Especially noticeable when the steering wheel to turn at a large angle. Therefore, you can maneuver on the ice, but very gently, delicately, sudden movements, he does not forgive. Generally on a slippery road distance between the cars must meet twice the speed. If you are moving at a speed of 30 km / h, the distance to the vehicle in front should be 60 m. The use of snow shaft for braking is particularly justified until the middle of winter, when snow still becomes caked - moving over to the car is almost not affected. In snow, the car stops very quickly - in this case the inertial forces tend to deploy it across the road. Move the snow to non-stop and switch gears. If you do not let a long jam slipping wheels. On the ice, especially the flat, the machine behaves in logical: brakes, accelerates helm. Harder to go to the rear wheel drive car, if it snows in the relatively warm weather, while on the road - wet mess. Here especially summarize broad, low-profile radial tires, even with excellent tread. The car suddenly for beginners, it may be unmanageable. Layer of compacted snow tire easily shifted down, just you try to brake or turn. In these circumstances, even moving in a straight line, the car can spontaneously enter into a skid, as the rear wheels tend to slip off the next, pressed on the front wheels and acting as if the rails. And as has been said in the beginning, without training you never see the skill of driving on winter roads. Exercise is better, where adhesion of tires with reduced coverage, but no more than two to three times compared with the usual asphalt. Powerful motor will perform any conceived by a reception. Very good for this area with groomed snow on a frosty day. Exercises are also necessary on the ice, but later, when they learn in the snow. Here is you will feel the treachery of ice! Hone your ability to keep the car on a given course in spite of drifts excellent help with the crackdown on full throttle on promorozhennaya, "dry" snow. Drivers are front-wheel drive, in varying degrees, mastered a new technique, often overestimate it. While the front wheels provide tractive force, the machine is obedient. Passing a slippery turn on front wheel drive car, the gas discharge is not recommended. Temptation holder front-drive cars fast, even on the ice, it is easily controlled - unlike the rear-wheel drive, which is already at low speeds start to "swim." The front-wheel scheme is particularly insidious when braking, not peculiar to classical. It is worth to remember everything.
