Many friends who drive will contact the underground garage every day. Parking in the underground garage can keep the car out of the wind and the sun, but many friends have experienced large and small accidents in the process of going up and down the basement, especially novice friends, Hoes and other accidents often occur in the narrow basement above and below. Below we summarize the issues that need attention in the process of going up and down the basement.
● Wear seat belts even if it is slow!
A horrifying accident happened a while ago. A novice female driver was killed in an underground garage due to an operating error. Putting aside the problems of unskilled driving and garage design, assuming that the female driver fastens her seat belt, the result will not be as serious as death.
Although the speed in the basement is not much faster than people walking, but even at this speed, there are dangers. For example, an occupant who hits a wall at 10km / h per hour may be injured due to forward inertia. If the driver is unskilled and the brake is mistaken for the accelerator, the danger factor is very large. The female driver in the above case is a good example. So we remind again: if the car starts to exercise, be sure to fasten your seat belt, even in the basement where the speed is not fast.
● The speed must not be fast / the direction must be precise
The entrance ramp of most underground garages is designed as a curve or spiral. This is to save limited floor space, so this increases the technical difficulty of entering the basement. I once saw a female friend in the basement. At that time, the head of the car hit the outside wall. There are two points to note here: speed and steering angle.
1.Speed-strictly follow the speed limit
When going down the basement, remember to slow down. Because the ground has an angle, the friction between the wheels and the ground is different from that on flat ground. It is more prone to understeer. Turn more outward, and finally rush out. It is recommended that when going downhill in a basement, whether it is a straight road or a ramp, you must strictly follow the speed limit of the basement. The speed limit in domestic basements is basically 5km / h. If the basement does not have a speed limit card, it is also necessary to consciously control the above safe speed limit.
2. Speed control: Use 1 gear for downhill, do not use neutral gear for sliding!
One more thing to note when going downhill is that you must not use neutral gear! Because the braking force required at this time is much larger than that on flat ground, it is more difficult to control the vehicle speed. If you lose the engine traction at this time, it will be very dangerous. So be sure to use 1st gear when going downhill, use the engine's reverse drag to limit vehicle speed, and cooperate with brake control. Manual automatic models need to use the manual mode to reduce the gear to the first gear. If it is an automatic gear model without the manual mode, hang the gear to the first gear or the L gear.
Even if the vehicle speed is controlled, if the position determination of the two "corners" of the front of the vehicle is not accurate enough, it is easy to occur on narrow basement ramps. It is suggested that for novice friends who have poor body measurements and space judgments, they can usually practice more, use wooden poles and other props to assist, and use the method of inside perspective + outside observation to strengthen the judgment of the two corner positions of the front of the car. In addition, for cars with longer wheelbases, pay attention to the margin of the rear, because the longer the wheelbase, the larger the inner wheel difference. If you only look at the front of the car, it may be inevitable that the rear of the car will bump into the wall. Don't be afraid of trouble, usually practice more in the car to avoid more trouble in the future.
● Don't press the line when going down the basement
The angle of the basement ramp is generally very large, so do not cross the solid yellow line in the middle, because when the up and down cars see each other, it is too late to react. Although the speed of the collision in the basement is not fast, but the responsibility is fixed. In terms of handling, it will be a lot more difficult than flat ground. In addition, blocking the entrance and exit of the basement not only affects the collision vehicles, but also delays the time of all people entering and leaving the basement.
● The car at the bottom of the chassis can go diagonally to the top and bottom of the slopePeerless King
Although the height of the car's head and tail from the ground, and the top and bottom of the basement are carefully designed, no bumps will occur during normal use. However, when lowering the basement, pay attention to the possibility that the lower edge of the front bumper may be injured. If you go on a steep slope, you should reduce the speed to a very slow speed when descending to the bottom of the slope. It is recommended to control the speed at 5km / h to pass through the bottom of the slope, otherwise it is likely to hit the lower edge of the front bumper. If the car is fully loaded and the body is pressed very low, you must also be careful when the up and down angles are relatively large. In extreme cases, you can use the oblique up and down method to avoid bumpers bumping into the ground.
● When entering the basement, wait for the car in front to drive away before proceeding
For novice friends, if you are worried about the level of your slope, simply wait for the front car to climb to the top of the slope to pass completely before starting. If you really do n’t know your level, you can follow the car in advance and let it wait to ensure that you have enough distance to make up for it after operating errors.
The following video is because the female driver driving the white car was too close to the car during the uphill process, which caused her to stop on the ramp, but her hill-lifting skills did not pass, which caused a collision with the vehicle in the rear. Harmony handled the matter very friendly, but as a novice and an inexperienced friend from Po Qi, it is recommended that you wait until the front car is fully on the slope and then start.
● Do not hang the D block or step on the clutch with the block when taking the card and paying the fee
You need to get a card when entering the parking lot. This seemingly simple action is also a security risk that cannot be ignored. In order to get the card conveniently and quickly, most people are used to stopping the car by pressing the brake when entering or leaving the parking lot. For old drivers who are skilled in driving, this may not cause any harm, but it is not recommended to do this "figure saving" operation. For novices, this operation is extremely prone to accidents, because at this time our attention is on taking cards and looking for money. It is likely that we have forgotten to block. If it is an automatic block, D block and stop When the foot accidentally left the brake pedal, the car slipped forward, and it was inevitable to walk in a narrow basement. If the car is manually blocked, it will definitely cause aggression and flameout when the foot leaves the clutch, scaring oneself and causing panic and confusion. If the car slips backwards, it will cause trouble.
● Turn the steering wheel over toll booth
When taking the card or paying the money, we need to bring the car close to the toll booth, but at this time our attention is on the close, and it is easy to ignore whether the steering wheel returns to normal after approaching. If the steering wheel does not return to normal, start again. There may be accidents like hitting a wall.
● Pay attention to height limit rods
In general, there will be height limit prompts and height limit rods at the basement entrance. It is best to have a general understanding of the height of the vehicle you are driving. Before you get off the basement, check to see if you have exceeded the limit height. It's also tricky to repair the car if it is injured. Although the chance of this problem is relatively small, it needs to be reminded.
● Use light reasonably
Underground garages are generally dimly lit, and the recognition rate of cars driving in the basement without lights is greatly reduced. This is especially true at the entrance. Generally speaking, there are curve reflectors at the ramps of the basement, so when driving in or out of the ramp, you should develop a good habit of using high beam lights to make it easier for the oncoming cars to find your car and increase safety. coefficient.
● The ventilation in the basement is not good. The lower basement is switched to the internal circulation.
There is also a detail that is beneficial to the health of the occupants in the car. It is necessary to develop the air conditioner to switch to the inner circulation before getting off the basement. If the window is opened, it is recommended to close it. Because the basement is generally not well ventilated, and the exhaust gas emitted by the car inside, the air in the basement is filled with "toxic gases" such as carbon monoxide, carbon dioxide, sulfur oxides. For a short time, you ca n’t put it out. If you forget to switch the inner loop every day, a long time will inevitably affect your health.
