Tires are easy to slip in rainy days, and the incidence of traffic accidents is about 30%~60% higher than that in sunny days.

At high speed, the vehicle speed is 120km/h, even faster. Once the road is wet and slippery, the tire slips and rolls over, and the mortality rate is almost 100%.

Decelerate ahead of time

First of all, if tire slippage is detected, the throttle will slowly loosen and the speed will decrease. The vehicle speed should be controlled within 100km/h/h, and the faster the vehicle speed, the easier the tire will slip.

Zhang Haiquan of Southeast University has a master's thesis "Study on typical vehicle braking behavior under wet and stagnant asphalt pavement conditions", which reads. The buoyancy of the water film on the tire varies with the speed of the vehicle. There is a critical water skiing speed, below which it is relatively safe to drive. According to its simulation research on the critical water skiing speed, it is concluded that the critical water skiing speed of ordinary family car tires is100 km/h/h.

One thing to note here is that since we have to slow down and drive so fast, there is a dangerous situation. I just let go of the whole throttle and started. This is also undesirable. Hou Lizhi published a paper entitled "We should form a good habit of operating the accelerator pedal smoothly" in Zhongnan Automobile Transportation magazine, which said. When the automobile is driving on rainy, muddy and icy roads, the road adhesion coefficient is small.

Don't slam on the brakes or release the accelerator.

The second is almost understandable. Just now, don't put the gas directly.

The second one, of course, is not a sudden stop, is it? After the vehicle skidded, the tire was lifted off the ground by water and lost its grip. When it suddenly braked, the tire got stuck. At this time, even if the ABS system is involved, it is very likely that it will be too late. We shouldn't take risks.

Don't fiddle with the steering wheel

The third thing to pay attention to is to hold the steering wheel with both hands. Don't move with one hand, don't mess with the other hand, don't hit the direction with the other hand, and stay where you are.

Zhang Chi published a paper "Traffic Risk Analysis of Expressway Waterlogged Section Based on Driving Dynamics" in the Journal of Traffic Information and Safety. The concept mentioned above is called "side slip angle of the center of mass", which is the included angle between the direction of vehicle movement and the longitudinal direction of the car body. As long as the included angle exceeds 5, there is a risk that the car will get out of control by pushing its head or swinging its tail.

When you encounter the possibility of slipping, or when you are already skiing, don't try to turn the steering wheel at once, fix it and bring it back. If you do this, it is likely to exceed the 5 just mentioned.

When I meet other cars, stay away from the water. Hearing this, some friends will ask: I have hit the car in front. It is always bad not to step on the brakes, and it is always bad not to hit the direction, right? Don't you just call? Therefore, it is very important to keep good habits when driving at high speed in rainy days. In addition to those mentioned just now, the safe distance between cars is also very important. Stay away from it and leave more room for braking and hitting.

So generally speaking, it is very important to keep the distance between cars when it rains.

If water is found on the road surface, try to control the speed within100 km/h/h. Below this speed, the family car will not easily float like a bar of soap on your sink.
