Matters needing attention in self-driving

First, when parking, try to put the front of the car outward. One is convenient for walking, and the other important function is anti-theft. Although this is not everything, if I am a thief, I only have the chance to steal a car.

Second, the principle of parallel driving is not to let the rear car step on the brakes. This is also the principle of crossing the road as a pedestrian. If you let him step on the brakes to avoid you, he may step on the gas pedal!

Third, you must slow down when crossing the intersection, whether it is a green light or not, at least you can't refuel, especially at intersections without traffic lights. In our country, many people don't cherish life, so don't compete with them!

Even if you are a novice, don't drive very slowly on the expressway, and it's the same on the loop or the elevated road. I often take the ring road, and I often see many big cars forcibly merging in order to overtake a car with a speed of only 40 kilometers per hour, which is very dangerous! Big trucks are difficult to start and run, so truck drivers don't like to step on the brakes. He would rather overtake in parallel than slow down to third gear and then spend 10 minutes to increase to fifth gear.

Don't follow too close when you are caught in a traffic jam or waiting for a red light. Unless someone wants to block it, at least leave a distance where you can break through. In case the front car breaks down, you will be added in the middle.

6. When queuing, in order to prevent others from being crowded, half of the car body should be set aside to one side of the car when it is blocked. For example, if you queue in the left lane, people often come from the straight lane to block it. You should try to press the right line of the left-turn lane with the right wheel, leave yourself room to go around to the left, and then follow the car in front, so it is difficult to get stuck.

Seven, when driving normally, the front car suddenly merges to give way to you, which is absolutely not good. Our driver hasn't realized this yet. Do not overtake with oil. It is best to loosen the oil immediately to prepare for braking, and at the same time quickly observe the rearview mirrors on both sides to determine which side to merge. You have a situation in front of you.

8. When you have trouble looking at other cars in the rearview mirror, you should turn on the light, not to see the road clearly, but to let others see you, especially when it rains during the day!

Six Points for Attention in go on road trip in Summer

1. Sunglasses should meet the requirements. The dark color of sunglasses will delay the time for the eyes to send images to the brain. This visual delay causes speed perception distortion and makes people make wrong judgments. Especially when the car is traveling at a speed of 80 kilometers per hour, too deep sunglasses will prolong the driver's response to the situation by 100 milliseconds and increase the sudden braking distance by 2.2 meters. Serious accidents often occur in this situation.

2. It is not advisable to overeat and drink cold drinks. During driving, most of human blood will flow into tense muscles to supply enough nutrition and transport waste, which will temporarily reduce the blood supply of gastrointestinal tract. At this time, if you eat a lot of cold drinks such as ice cream, it will cause sudden contraction of gastrointestinal blood vessels and decrease of blood flow, which will often cause physiological dysfunction, affect the digestion of food, and may also cause gastrointestinal diseases such as abdominal pain and diarrhea. Therefore, drinking cold drinks in summer is not as good as drinking hot tea, because hot tea can dilate capillaries, open sweat pores, relax sweat glands, and sweat freely, which is beneficial to the body to emit heat. Theophylline in tea also has diuretic effect.

3. Gas lighters should not be used. Some drivers put gas lighters on the hood after lighting cigarettes, which is very dangerous. Disposable gas lighters have a plastic container filled with liquefied gas. When the container is hit or the temperature reaches above 40℃, the gas will expand when heated, and the plastic shell will explode due to the impact or heating. Once a fire breaks out, the consequences are unimaginable.

4. Tighten the water tank cover. At high temperature, evaporation of oil and water will naturally increase. The fuel tank cover should be tightly covered, and the oil pipe should be prevented from leaking; Always check the water level of the water tank, the oil level and height of the crankcase, the brake fluid level in the brake master cylinder, the electrolyte density and level in the battery, etc. When the working oil is insufficient, it should be replenished in time according to the regulations.

5. Avoid driving for a long time. In hot summer, you should try to avoid driving for a long time. Pay attention to rest in time when driving. Try to park in a cool and ventilated place. If the pointer of the thermometer has pointed to the near-high temperature area, you must stop the car and turn off the engine to "cool down". If the radiator is cooled with water, be careful not to wet the pipeline. It is best to develop the good habit of cleaning the radiator regularly, which can improve the heat dissipation effect of the engine and reduce the overheating of the engine. Pay attention to the fact that the fan belt can't stick oil during maintenance to prevent slipping.

How to pay attention to safety in go on road trip in autumn and winter

1. Know the weather of the destination in advance. In autumn and winter, the weather is changeable, and rainy weather often occurs. So before you leave, you should know the weather at the destination and bring umbrellas and other rain-proof tools. If you encounter bad weather such as fog and rainstorm, it is best to change the travel time or route to avoid traffic problems or mudslides and landslides caused by bad weather and ensure travel safety.

2. Design the route in advance. The tourist route can be divided into two parts. First, determine the scenic spots to go. After determining the scenic spots, you must choose a good driving route. The choice of driving route should follow the principle of expressway first, then national highway. At the same time, according to the map and the information provided by friends who are familiar with the route, we can know the location of road conditions, food, accommodation, gas stations and so on. Try to choose regular scenic spots and try not to be curious.

3. Check the driving experience of different types of vehicles before departure, and it is very important to be familiar with the driving characteristics of vehicles before going out. Before traveling, the vehicle should be thoroughly inspected, including whether there is oil leakage or water leakage (see if there are traces of oil and sewage on the ground under the vehicle); Measure the tire pressure to see if it is appropriate; Check the oil condition (pull out the dipstick to see if the oil color on it is normal and the oil height is appropriate); Check whether the spare tire is intact; Wait a minute. If the car rental company rents a car, the inspection of the car rental company has been completed, but it needs to be checked again when picking up the car.

4. Pay attention to the road conditions on the road. In addition to weather factors, road information and driving safety are also very important to drivers, especially in foggy autumn and winter. It's best to ask for directions in advance, get accurate information and avoid unnecessary troubles on the road. It should be noted that the number of ice and snow days increases in autumn and winter. There will be rain and snow in many places in the north, so we must pay attention to slow down. In addition, no overtaking, no overloading, no fatigue driving and no drunk driving. It is best to install GPS satellite navigation system on the vehicle. On the one hand, it is convenient to know the road conditions, and at the same time it is helpful to locate quickly when encountering accidents.

Matters needing attention in self-driving ice and snow tourism in winter

1. The winter temperature in the north is about -30℃~o℃, and it will be lower than -30℃ in some places. It should be all down jackets (hats are best), high-necked thick sweaters, wool pants, down pants, gloves and so on. If you go to the Qinling Mountains and the north of the Yangtze River, you must wear Gao Xue cotton shoes. In winter, there is snow and ice on the northern roads, and the roads are slippery, so it is easy to slip when wearing leather shoes. It is best to wear snow-proof cotton shoes or sports shoes, and remember not to wear leather shoes, otherwise it will be inconvenient to move.

2. The snow pit is located in the snowfield near the sea. Most of the original roads are covered with snow. When the road is unclear, don't rush forward. You need to find the trunk as a staff and find out the depth before you can move forward. If you fall into a snow pit, don't struggle, because the more you struggle, the deeper you get, and you have to wait for help.

3. Many places in the north are anti-skid, and the roads are covered with snow and ice in winter, so the tires are easy to slip. So every tire should have a snow chain. When there is snow and ice on the road, it is necessary to add snow chains to the wheels.

4. Most of the freezing in northern winter is below 0℃. When turning off the fire at night, drain the water in the water tank by the way, otherwise the water will freeze after a night of frost, or it will be replaced by an unfrozen liquid.

5. Prevention of diseases, easy to catch a cold in winter, and travel to Gan Yang porn and other drugs for treating colds; Northerners love cold dishes, and people who are not used to it are prone to nausea. They need antidiarrheal drugs such as berberine. Dry mouth in the north needs heat-clearing granules such as Xiasangju and Huanglaoji.

6. Anti-snow blindness In winter, there is snow in the north, and the snow is highly reflective. You need to wear sunglasses to protect your eyes when you go out.

How to take a bumpy country road by car?

1. Control the speed. There are many obstacles such as potholes and gravel on the dirt road, so the driving speed should not be too fast, otherwise the vibration of the vehicle will be aggravated, which will not only damage the transmission system and driving system of the vehicle, but also directly threaten the driving safety. Especially in rainy days, when driving on roads with stagnant water and mud, you must stabilize the throttle and control the speed. Even if you need to slow down, you must control it by reducing the throttle.

2. When there are potholes and rocks on the road surface, consider the ground clearance of the vehicle and carefully turn the steering wheel to avoid them. Be especially careful when passing through soft, muddy and stagnant sections. If necessary, you should get off and observe first. When it is determined that the wheels will not sink into the soil, you can slowly pass through the low gear. If the newly opened dirt road has ruts, try to drive along the ruts, and don't take risks blindly.

3. Be careful when going downhill. Whether it's sunny or rainy, you should choose the medium and low speed gear when going downhill, reduce the throttle and go downhill slowly, and don't slip downhill in neutral. Because the dirt road is bumpy, rocky and complicated, it is often necessary to brake and slow down on the way down the mountain to avoid it, especially when some dirt roads have sharp bends on the way down the mountain. If they slide down the slope in neutral, it is easy to cause major accidents such as vehicle deviation, side throw or even rollover when braking.

4. When driving safely, don't get too close to the car in front, so as to avoid the dust raised by the car before sunny days or the muddy water splashed in rainy days blocking the line of sight. Pay attention to the road surface during the meeting, especially don't be too close to the shoulder in the rain, in case of accidents caused by vehicle sideslip.

5. Prevent sideslip. When the front wheel slips, you should stabilize the throttle and correct the direction and driver. When the rear wheel slips, turn the steering wheel in the slipping direction, and drive in the loop after the rear wheel is straightened. If the rear wheel slips sideways when going downhill, you can step on the accelerator appropriately to accelerate. After the sideslip is eliminated, drive at the original speed. How to drive through mountains, water and sand?

1. The mountain climbing road is characterized by long and steep slope, narrow and sharp bend and limited vision. When driving, always pay attention to the road conditions, the steering timing should be accurate, the gear shifting action should be rapid, and at the same time, pay attention to various traffic signs so as to take measures in advance. When crossing dangerous mountain roads with mountains, cliffs or rivers, you should keep a low speed and drive carefully. Slow down and whistle when turning.

2. The wading vehicle has poor wading ability. When the water depth is more than half of the height of automobile tires, it is not advisable to risk wading. When wading, you should put on a low gear, so that the car can smoothly enter the water from the shore and avoid splashing. Keep the engine with enough power when driving, and avoid stopping, shifting gears or slamming the steering wheel. Keep your eyes on the fixed Japanese standard, not on the running water, so as not to interfere with your vision and make a mistake in your direction. After landing, drive at a low speed for a certain distance, and lightly step on the brake pedal several times to make the brake shoe rub against the brake drum.

The attached moisture is heated and evaporated, and after the braking efficiency is restored, it turns to normal driving.

3. When there is sand in front of the sand outlet, it must be accelerated in advance, and the oil can not be collected until it is all passed. When crossing the soft sand, never stop, keep the wheels turning at a constant speed. Otherwise, once the car stops, it will be difficult to start again. When a car passes through the sand, it sometimes feels that the wheels encounter strong resistance because the sand is too soft. At this time, the speed will obviously slow down. Don't panic, step on the gas a little and try to increase the speed. When driving in the sand, don't suddenly increase the throttle, because this may cause a driving wheel to idle, and the car will lose its driving force and fall into the sand.
