This morning, on the first day of work in the Year of the Tiger, it snowed heavily in Hangzhou. There is snow in many parts of the city, and many people rush to the West Lake and the suburbs to see the snow. Snow viewing is not to be missed, but it is also necessary to pay attention to driving safety. Orange Persimmon Interactive reporter synthesized the opinions of many industry insiders and sorted out some driving references for everyone:
First, check and add antifreeze. Because there is less cold weather in the south, some owners may add ordinary tap water to the antifreeze, the original antifreeze will be diluted, resulting in a decrease in the freezing point of the antifreeze, then in the ice and snow weather, parking the car outside may make the diluted antifreeze freeze, when driving it is easy to make the engine water temperature too high, and even lead to damage to the engine parts, so it is best to replace the antifreeze.
Second, maintain appropriate tire pressure. Winter temperature is low, according to the principle of thermal expansion and contraction, the tire pressure of the tire will also change, the owner should appropriately increase the tire pressure to reduce the tire wear consumption, it is recommended to maintain a tire pressure of 10 to 15% higher than the standard, but can not exceed the maximum tire pressure specified in the product manual. It should be noted that in the case of ice and slippery road surface, the tire pressure is too high will affect the adhesion of the tire, at which time the owner should appropriately reduce the tire pressure. In addition, in the cold winter, the car owner often checks the tire pressure, and when the tire pressure is insufficient, the tire pressure should be replenished in time to protect the tire pressure.
Third, warm water to remove ice and snow, pay attention to water temperature. Old drivers all know that the window ice can be washed with warm water, but be sure to pay attention to the water temperature, do not use boiling water, otherwise it may damage the window glass, and damage the wiper rubber strip and paint. Snow driving, the first thing to face is that the wiper is frozen on the windshield, do not force the windshield to open the wiper, will hurt the rubber sheet on the wiper, and even burn the wiper motor, it is recommended to put the wiper up when stopping, to avoid the wiper being frozen.
Fourth, wear sunglasses to prevent dazzling. If the snow is very large, there will be snow on the ground, when driving, the surrounding white expanse, the reflected sunlight is very dazzling, it is easy to make the eyes tired, so it is best to wear sunglasses when driving to avoid vertigo.
Fifth, defogging and defrosting, keep the line of sight clear. In ice and snow weather, the front windshield is prone to fogging, affecting the driving vision. Cars are generally equipped with front wind gear defrost, rear window / exterior mirror heating function (many low-end models are not equipped), when driving, if the front windshield fogging, after pressing the corresponding button, you can quickly remove the fog and frost on the front window, rear window, exterior rearview mirror.
The front windshield defogging button is a wavy line logo with three arrows up, and the rear windshield defogging button is a rectangular wavy line logo with three arrows up. You can also open the air conditioning refrigeration function, and then open the external circulation, adjust the air conditioning outlet to the maximum air volume, only ten seconds, the fog on the glass will disappear. If the car is not equipped with an external mirror electric heating function, you can prepare a cotton cloth, and you can wipe the rearview mirror clean at any time when you stop and wait for the red light.
Sixth, maintain the distance between the vehicles, strictly prevent sharp braking. Ice and snow weather, snow and ice on the road make the road surface more slippery, tire adhesion is reduced, the braking distance will become longer, so when driving, you must pay attention to controlling the speed (it is best not to exceed 40 yards), and maintain a certain safe distance with the car in front (the distance is best kept at 2-3 times the usual), and do not overtake at will.
If you follow the car too closely, it is easy to have a rear-end accident. In case of emergency, do not slam on the brakes with one foot, which can easily lead to the side of the vehicle. Before braking, you should tap the brakes a few times to slowly stop the vehicle, and also remind the rear car to concentrate. Drive in places where the snow is deep, and try to follow the ruts in front of you to prevent falling into the deep snow.
With the increase in electric vehicles, driving electric vehicles in ice and snow weather should pay attention to the above matters as well as fuel vehicles, and also pay attention to the following matters:
1. Timely charging and full power travel. Because the mileage of electric vehicles is limited, especially in winter due to the impact of temperature drops, the endurance will generally decline by 30%-50%, and it must be fully charged before departure. Generally, the remaining 100 kilometers of endurance must be charged as soon as possible. In winter, if you do not drive for a long time, it is best to charge it every three days, which is very important to keep the car battery active.
2. Plan the charging point in advance. Before driving an electric car, be sure to plan your travel route and know where to recharge. Generally, there are charging piles in the service area of the high-speed, but there may be many cars queuing up in front of the charging piles, and they need to wait. In the countryside, where there are charging piles, try to replenish the electricity as soon as possible.
3. Try not to park outdoors. In the low temperature environment in winter, the chemical reaction of the power battery will slow down, resulting in a decrease in performance, a decrease in charge and discharge, and a shrinking mileage. Therefore, try not to park outdoors, if there is really no indoor parking environment, you can add a piece of clothing to the vehicle when parking; it is also best not to charge in the outdoor open air, low temperature weather will reduce charging efficiency.
4. Control the temperature of the air conditioner and save electricity. Electric vehicles because there is no engine heat dissipation, so air conditioning heating is achieved by converting heat from electrical energy, so the air conditioner in the winter driving will consume a lot of electrical energy, which makes the mileage shrink. Therefore, it is necessary to make rational use of air conditioning and reduce the temperature of air conditioning appropriately to save electric energy. It is also possible to keep the interior of the car warmed with less power consumption, seat heating and steering wheel heating.
In short, when traveling on snow days, drivers must pay attention to observing the road conditions, reasonably planning travel routes, encounter intersections, crosswalks, and be sure to give way to pedestrians and slow down! To drive an electric vehicle on an ice and snowy road, you should use a small throttle to start. Because the motor torque release is very fast, it is easy to slip, planing, tailing, especially when the vehicle starts and accelerates, try to use the economic mode small throttle to drive the vehicle.
The key to driving on snowy days is to be "slow" and be sure to maintain a good driving mentality.
