During braking on wet roads, what is the correct

by:DEFUS     2020-05-24
There are two situations that I can think of when the brakes on the slippery road are offset. The first case: the front wheel is locked and the direction is out of control When the car turns, the steering wheel deflects, and the ground generates static friction on the side of the tire to make the tire roll in the direction it points. If the tire is locked, there will be a very large resistance in the tire rolling direction. This resistance is much greater than the static friction of the ground against the side of the tire, so after the tire is locked, the friction of the tire will break through the ground and begin to slide forward. No matter how you move the steering wheel, the car will not have any steering action. It is very dangerous for a car to have no steering ability, as long as the steering wheel is locked, it will inevitably lose its steering. The well-known ABS is to avoid steering failure caused by tire lock. The only effective and very effective method when steering failure occurs due to tire lock is to immediately release the brakes, as soon as the steering wheel resumes its direction of rotation and immediately recovers. Unfortunately, the vast majority of drivers can't release the brakes even after the front wheel is locked and the steering is out of control, because in that emergency, people instinctively step on the brakes, even if they know they are useless. Therefore, the first encounter without the front wheel lock is often based on luck, and the car stops. If you are out of luck, you run into it. Therefore, I suggest that car owners without ABS can actively try the feeling of losing the steering after the brake is locked under the right circumstances, and then experience the feeling of regaining the direction of the brake release. In this way, when you encounter such a situation, you will have greater control over the vehicle. The second situation: the direction is too fierce, leading to dumping When braking on wet roads, the center of gravity moves to the front wheels, and the rear wheel grip decreases. At this time, flicking the direction is prone to flick. In the event of a tail flick, the vehicle will turn around in place, while in the other case, the vehicle will roll out of control or cause a serious collision. The most effective method when tail flicking occurs is to alleviate and correct by changing the direction. The principle is: where the rear of the car is deflected, the direction is towards which side. For example, in the picture above, the rear of the car is sliding toward the driver's right side. All the driver has to do is quickly turn to the right, so that the danger can be resolved. Although the two situations mentioned above can be turned into danger with reasonable and effective intervention, to be honest, many times not only rely on technology, but also on luck. Not all drivers can resolve the crisis when they encounter this situation. So I think it makes more sense to avoid dangerous situations. Here are some experiences to share with you. 1. Prevent in advance. For example, when you want to overtake on a slippery road, you can change lanes in advance, so that we have enough time and distance to change lanes, and the direction does not need to be too fierce. And when you approach the road before you change lanes because of too little time and distance, the direction is naturally more, and it is more likely to flick. 2. Try to avoid stepping on the brakes when turning, for example, fully decelerating on a straight road in advance when passing a curve, and then pass the curve at a low speed. This can avoid stepping on the brakes in a curve and reduce the risk of losing control.
