How to drive an automatic car in rain and snow?

Long time no see, old friend. I haven't updated it because of something at home. The temperature has plummeted these days, and it is expected that there will be a blizzard for several days. Today, we will talk about the problem of safe driving in snowy days and make a discussion. Welcome experienced people to discuss and share in the discussion forum.

On snowy days, it is not an exaggeration to drive at 80, 60 or even 30 km/h on the expressway.

Slow enough speed is the first rule to ensure the safety of driving in ice and snow. In case the vehicle is out of control and needs to slow down, it is advisable to use the traction of the engine to gradually control the speed, and then gently step on the brakes continuously to make the vehicle stop completely. Many novices who drive automatic gears only know P, R, N and D gears, and L and 2 gears have no idea what they are for. Master Wang said that under special circumstances, the automatic gear should also use two gears, L and 2, to prevent the vehicle from sliding forward.

Different models behave differently in ice and snow. Four-wheel drive models have uniform power distribution, and each wheel is a power tire, which is not easy to slip or fall. Automatic transmission models equipped with snow mode can adapt to the start and driving in snow and ice, which is very helpful for novice drivers; Manual gear depends more on the driver's experience and skills.

However, no matter what kind of car, it is inevitable that it will suddenly lose its grip on the snow and ice ground. Therefore, never start suddenly or brake suddenly, which is the common rule of all cars. During driving, when the snow on the road surface is deep, try to walk on the track driven by other vehicles or on the road surface dried by vehicles.

Whether going uphill or downhill, it is advisable to use low gear. When going uphill, you may suddenly lose power because the tires slip. Low gear can provide more torque to offset the wet ground and make the vehicle more dynamic. When going downhill, you can keep a proper speed by the traction of the engine. When you start downhill on a slope of 20 degrees, you can successfully control the speed within 20km/h without braking in the first gear. In addition, if the vehicle is equipped with an automatic limit switch, the limit switch can be turned on to prevent the vehicle from automatically shifting into the fourth gear, so as to ensure sufficient power of the vehicle and limit the speed too fast.

The turning speed of the vehicle shall not exceed 20km/h.

Driving and turning on icy roads is also a headache for novices. If you are not careful, it may cause the vehicle to slip out of control. Master Wang said that many snow traffic accidents were caused by drivers turning at high speed. Some don't know if they should turn at a low speed, and some suddenly hit the direction in an emergency. He said, control the speed and give yourself enough reaction time to deal with emergencies. When turning, the speed should be slow and the angle should be small. If the vehicle is driving forward when turning, you should relax the throttle and reduce the turning angle of the front wheel until the front wheel is controlled, and then turn the steering wheel in the direction you want.

It is best to control the turning speed on ice at 10- 15km/h, and do not exceed 20km/h when turning on snow.

When the vehicle skids, tap the steering wheel in the sliding direction.

Another mistake that beginners are most likely to make. In which direction does the front of the car tilt? On the conventional road, it is known that it can only be corrected by hitting the car body in the opposite direction, but it will speed up the vehicle crossing on the ice that has already started to slip. The correct way is to turn the steering wheel slightly in the slipping direction, and then slowly correct the driving direction after completely controlling the direction and speed of the vehicle.

When the vehicle slips, the most important thing is to keep a calm mind. Extraordinary problems are handled with a normal mind, and there will be confusion in a hurry. In addition, if the tires slip when starting or climbing on the ice, you can sprinkle some sand, gravel or coarse salt in front of the wheels to reduce the slippage. You can also spread rough items such as felt and straw mats. It is unlikely to slip in the snow in Changsha. If it happens, you can try to get out of the snow pit. If not, you need to find something hard to put in front of the tire and start it slowly.

[Friendly reminder]

Expressway can't take the expressway.

Super novices often despise the driving skills in expressway. They always think that the straight road only needs to control the throttle and brakes, and even the steering wheel is too lazy to move. What's the difficulty? Yes, but I didn't know that the extraordinary situation in expressway required extraordinary experience. On February 2-3, 654381October, dozens of serial rear-end collisions occurred in expressway, Hunan Province, which really deserved the name of "free maintenance, welcome rear-end collisions".

Therefore, we advise the super novices not to take the technical examination with the mentality of laughing at expressway. If you must travel, you'd better choose public transportation. It is much safer to give your life to others than to take it into your own hands. Expressway serial rear-end collision is the most prone accident in the snow. For beginners, we should strictly implement the concept of "stopping for three minutes without grabbing a second". There is no more skill to prevent rear-end collision. Keeping a safe distance four times longer than usual and keeping a safe speed is the right way. It is not an exaggeration to reduce the speed to 80, 60 or even 30 km/h, especially when passing through the construction section, it is necessary to control the speed.

What needs to be reminded is that expressway does not change lanes at will, but respects his own life and that of others. If there is an accident or malfunction, put a warning sign at least 200-400 meters behind the car. People must not stay in the car, stand on the shoulder of the road, or even stay by the car. It is safe to stand outside the guardrail and wait for rescue. If the road traffic deteriorates or heavy snow affects the line of sight, if you plan to stop and wait, it is also very dangerous to stop at the shoulder, and usually the relatively safe port is not safe. It is best to enter the service area as far as possible, so as to ensure the safety of vehicles and not cut off the supply on the road in the case of continuous deterioration of weather.
