How to drive an automatic car uphill? How to drive downhill with automatic transmission

Although the automatic transmission is indeed much more comfortable than the manual transmission, it is not possible to drive the automatic transmission car when it is always hung in D gear, and you still have to switch different gears in different road sections. For example, when the automatic transmission is uphill, just stepping on the accelerator is actually a wrong operation.

First of all, when the automatic transmission is uphill, you must put on the accelerator to refuel slowly, don't step too fast, so that it may be dangerous, and at the same time when going downhill, you must use a low gear, you can change to a first gear, he should not step on the accelerator, because he can slide down directly, and then be sure to control your speed with your right foot, and be sure to tighten the handbrake when you get on, and then go to the gear, and then everything is to pay attention.

Automatic transmission uphill, it is recommended to step on the accelerator before going uphill, use inertia to pass the ramp, and secondly, you can also switch to the low gear for climbing, so that the power is more sufficient.

Hang D gear, step on the accelerator, and pay attention to the general slope to hang D gear.

For automatic transmission models, many times it is "D gear to go all over the world", this method is no problem in the Pingchuan area, but if it is in a section with more ramps, such as mountainous areas, it is debatable. Because of the automatic transmission model, in addition to the four fixed gears of P, R, N, D, there are other gears.

Method steps.

1. Under normal circumstances, automatic transmission cars are driven in normal D gear, but D gear has a big drawback, that is, the engine braking almost does not work. When walking on a long downhill road, be sure not to drive in D gear to prevent accidents.

2. If you open the automatic transmission, no matter how long and steep the slope you go down, the old driver must use the D gear to cooperate with the brakes to drive, and the significance of hanging the S gear is not much, and the brake is the king. Sudden braking may cause brake failure, please use point brake on long downhill slopes, that is, slowly and lightly apply the brakes several times to reduce the speed of the vehicle, so that the speed of the vehicle can maintain a constant speed in the downhill road.

3. The cruise control cannot be controlled at all; It is recommended to use it if you don't understand the situation. The manual mode of the manual self-integration can be locked, and the manual mode can be used for the manual mode, but pay attention to the gear change.

4. An ordinary car running more than ten kilometers down the mountain road is enough to make you choke the burning smell in the cockpit after you click the brakes hundreds of times. The best way to do this is to take a break in the roadside parking area every few kilometers to give the brakes a chance to cool down.

5. Pay attention to the road conditions and step on the brakes in case of emergency. If you are unlucky, brake failure, don't panic; Repeatedly loosen and press the brakes several times, and the brakes have a chance to recover; Hold the steering wheel tightly, don't let the car go crooked, and pull the handbrake.

6. If nothing is ineffective, finding a safe place and crashing into it is the last choice. On the downhill road, there is a cliff on one side and a mountain on the other, and you can't brake, so you can lean towards the mountain and stop by reducing the speed of the car with the help of friction.

The correct way to go downhill with automatic transmission is:

1. When going downhill, change the gear to L gear, use the foot brake, and remember not to hang N gear;

2. Can not slide in neutral gear, the automatic transmission needs to be lubricated, when the gear is placed on N during driving, the oil pump can not supply oil normally for lubrication;

3. Under normal circumstances, you can brake with D gear with the point of downhill, if it is a large slope, use L gear to control the speed or use the manual mode to add and decrease gears to control the speed;

4. Pay attention to the road conditions, step on the brakes in case of emergency, if the brakes fail, you can repeatedly release the brakes several times, the brakes have a chance to recover, hold the steering wheel tightly, don't let the car go crooked, pull the handbrake.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing power, after buying a car does not affect the overall quality of life of the family, generally according to the average income of the family in the past three years, generally take out 20% of the family for three years, but not more than 10% of the value of the family's fixed assets.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store to confirm on the spot, including test drive, inquiry, loan, repair and maintenance, and other related information.

Automatic transmission vehicles, when going downhill, do not brake for a long time, automatic transmission or manual vehicles, switch the gearbox to the low-speed gear of manual mode, or switch to the L gear with L gear, and use the gearbox braking to cooperate with the brake to control the speed.

When going downhill, the car must not hang the gear in N gear, which will cause damage to the gearbox, and the speed is not easy to control, and the brake pads are easy to overheat, and the speed is out of control. For long downhill slopes with a general slope but a long downhill distance, first switch the vehicle to manual mode, and then use manual mode to adjust to the third gear of manual mode, and use the engine braking to cooperate with braking.

Precautions for driving downhill.

Before going downhill, you should test whether the braking performance is good, if there is a fault, you should go downhill after eliminating the fault, and use braking with caution on the downhill section.

Do not slam the steering wheel on the downhill section, because the downhill section has a large inertia, fast speed and improper use of the steering wheel is easy to cause overturning.

The distance from the vehicle in front should be kept at least 50 meters. If the slope is too long and the inertia of the car is very large, the distance between the workshops should be increased appropriately.

If you drive downhill and then uphill, when you are close to the bottom of the slope, you should be ready to rush the slope, release the brake pedal in time, and shift into high-speed gear in time.

If the downhill is not very long, and not very steep, D gear release the throttle, the use of engine traction can be slowly and uniformly downhill, the speed is too fast in the process can be lightly stepped on the brake to adjust the speed, if it is a very long or very steep downhill road, then you can hang into D2 or D3, to control the gear, D2 means the highest to 2nd gear, will not rise to 3rd gear, D3 is the highest to 3rd gear, in this way, you can make full use of the traction of the engine to effectively control the speed.

When the automatic transmission car is going downhill, it is forbidden to coast in N gear, and it must be engaged in forward gear.

How do you go downhill when driving an automatic car? It's not right to put on the brakes in D gear, it's safe to do so!

How to drive an automatic transmission car with a small displacement uphill?

I have the same opinion as you, and I have done this in practice, which is not steep or long.

Just step on the brakes, if it's a manual one, push it to the hand gear, use the first gear to pull down, and you don't need to step on the brakes.

In the past, cars were basically manual transmission, but with the development of technology, the vast majority of cars are now automatic transmission. The automatic transmission saves a lot of trouble compared to the manual transmission, there is no clutch, only the accelerator and brake. Therefore, it will be easier to go uphill with an automatic transmission, and you only need to press the accelerator to go uphill smoothly.

Novices who have just learned to drive do not have to worry about landslides when going uphill, and they can apply the brakes in time even if the car slides.

It is easy to go uphill with automatic transmission, there are a total of five items when taking the driver's license test, side parking, reversing into the garage, S curve, right-angle turning and half-slope start, and the most difficult of these five test items, and it is also recognized by everyone that is half-slope start. Because it is easy to slip or suddenly turn off in the middle of the road, but this kind of thing will only need to be worried about when taking the manual transmission test, and automatic transmission will not have these problems.

Since June 1, 2021, the automatic transmission test has been changed from the original five to four, and the half-slope start has been cancelled directly. Therefore, it shows that the test item of half-hill start is not difficult at all for automatic transmission vehicles, and there is no need to exist. But after learning this news, the candidates still felt extremely excited, after all, one less item, then the possibility of passing the test will also increase.

Although it is said that there is no need to take the half-slope start test in the exam, there are still many applications of the half-slope start in life.

In the parking lot, you often encounter a half-slope start, and the most common scene is when you come up from the parking lot, there will be a lot of vehicles going out of the parking lot, and they are queuing to go out. When the previous vehicle has not been driven out normally, the car you drive must be parked in the middle of the slope and wait for the vehicle above to complete the payment, so at this time you can show the importance of starting the half slope. As a novice, you don't have to panic, just put the brakes down before starting and press the accelerator to move forward.

In fact, the reason is very simple, if you step on the accelerator with D gear, once the power is insufficient, there will be a slip phenomenon, and the transmission will be damaged in serious cases. Then, the general practice of old drivers is to hang L gear uphill, so that the engine is maintained at a higher speed, maintain the maximum torque output, and it is more convenient to go uphill, which can effectively prevent rolling.

When you drive the automatic transmission uphill, you can go to the D gear, and then step on the accelerator to accelerate uphill, or there are some vehicles with S gear on it, and you can directly hang into the S gear to meet your own needs for going uphill.

We can switch to D gear and slam on the brakes on the uphill slope so that we can go uphill.

Just step on the accelerator, keep the speed of the car, don't slow down, otherwise you may slip, and pay attention to acceleration when going uphill.

Natural acceleration occurs when going downhill. Brake failure can occur when the speed is too high, which is very dangerous. Therefore, it is important to control your speed and descend slowly.

When operating downhill, do not mistakenly think that you can slow down at any time as long as you apply the brakes. Frequent use of braking can cause the braking device to overheat, and the car will cause bubbles of fuel in the pipes due to high temperatures, causing the engine to stall or brake poorly. Therefore, when going downhill, it is necessary to use the method of engine braking as the main method, supplemented by foot brake braking for deceleration operation.

How to drive an automatic car downhill.

Tip: Under normal circumstances, automatic transmission cars are driven in normal D gear, but D gear has a big drawback, that is, the engine braking almost does not work.

When the engine brake is required on the downhill slope, if the slope is small, as long as the ignition system is turned off, the engine braking can barely play a little role, and then the foot brake can be used to smoothly go downhill. If the slope is very steep and the speed cannot be controlled by the above actions alone, you must change to 2nd gear. Braking only works in 2nd gear, and most downhill climbs are done this way.

If you need to brake frequently even when the engine is in 2nd gear, switch to L gear. Engine braking is strongest in 1st gear, to the point where you sometimes have to press the throttle gently to get a smooth descent.

Automatic cars have been designed with this in mind, and this is the use of the gear indicated at the shift marker, which is forced to resist. This is because the automatic transmission gets faster and faster due to the acceleration of gravity when going downhill, and in order to overcome this phenomenon, a forced reverse gear has been added to the transmission.

When you engage the 1st gear position, the transmission only has one gear in one gear; When 3rd gear is engaged, there will be a gear, and it will switch between these three gears according to the road conditions, and will not go up to 4th or even 5th gear. This is the function of forced blocking, also known as downhill gear.

Now, the car gear type is divided into two types, automatic transmission and manual transmission, even people who don't know the car know, automatic transmission is suitable for friends who have just learned to drive, simple and easy to control, manual transmission is relatively complicated, the general old driver will choose to open the manual transmission, because its driving is more comfortable and free.

The steps for an automatic transmission car to start uphill are as follows:

1. Pay attention to the tachometer in the dashboard (the table on the left in the figure), the engine speed is generally above 1000 rpm when the cold car starts, wait for about 10 seconds, and wait for the speed to below 1000 rpm. When the rpm reaches 1000 rpm or less, press the brake with your right foot and lower the handbrake with your right hand.

2. Shift the gear from P to D. The P gear is the parking gear, and the D gear is the forward gear. (Note that the right foot is still on the brake at this time).

3. When the slope is very steep, quickly release the brakes, quickly give the throttle, and the throttle is slightly larger. Of course, you should also pay attention to the fact that there are no obstacles in front to prevent rear-end collisions.

The automatic transmission car starts basically the same as the manual, and the general slope D gear or afterburner third gear.

Steps:1Pull the handbrake and the car stops.

Put it in D gear and start accelerating before going uphill according to the slope - > slightly increase the throttle when you feel the lack of power - > gradually release the accelerator pedal when you are close to the top of the slope, and use inertia to "slide" over the top of the slope (because it is uphill, the throttle is also released to achieve the purpose of deceleration, and the fuel consumption is also reduced. If you still accelerate to the top of the slope with all your might, the speed of the vehicle will suddenly increase when going downhill, and braking again will waste fuel).

Start the car in P gear, then apply the brakes and shift to D gear (on a gentle slope). (Steep slope) shift to S or L. Release the handbrake first, then slowly release the brake, and finally slowly refuel.

Tell you, after starting, step on the brakes, hang into D gear, floor oil (or not so big, give oil 4000 rpm), release the handbrake, release the brake, O, uphill start, or ejection (premise: the engine should be strong, and the tires should grip the ground well).
