How do you drive an automatic car uphill and downhill?

It should be noted that the L gear of the automatic transmission is a low-speed gear, which is equivalent to the first and second gears of a manual transmission car. When the speed of the car is fast, it is not allowed to engage the L gear, which will impact the gearbox. However, the L gear can be directly attached to the D or S gear.

<> the most common uphill and downhill scenario in daily urban commuting is the up and down of the basement, the following is to take the up and down of the basement as an example to briefly talk about the brakes to be pressed to death at one time, and try to avoid the thermal attenuation of the brakes caused by long-term braking, resulting in a decrease in brake braking force. Reduce the speed of the car to about 15-20 kilometers per hour as much as possible, which is equivalent to the first gear position of the manual transmission. Of course, some cars now also have a manual self-integration.

Push it up to D1, and then push it to D2It is also equivalent to the first and second gears of manual transmission, and the first and second gears are used uphill, depending on the size of the slope, and the low gear and high speed are uphill; Downhill, also in first gear or low gear, using the low speed of the engine to open the control.

The driving computer will issue instructions according to the driving state to upshift and downshift, but the particularity of the uphill slope will make the vehicle frequently upshift, and there will be frequent "drag gear" state, not only the power is weak and the power output is not smooth, but also more likely to produce product Not long ago, a relative of mine who has been working in Pingchuan returned to his hometown to play. He is middle-aged, and his driver's license has been obtained for a few years, but the car has just been picked up for more than a month.

Just use the D gear, and the transmission will automatically detect the load of the car and will not automatically upshift. Many car critics say that the L gear is used uphill, which is a statement that does not understand the principle of the gearbox! L gear is not uphill, L gear when the hydraulic change is also for the automatic transmission car uphill and downhill how to drive, there is not much talk and operation,I think it's perfectly possible to go up and down the hill in D gear and cooperate with the brakes at the same time, but I want to emphasize that you must not coast in neutral gear!

You have turned on the automatic transmission, isn't it just for the convenience of the picture, there is no manual gear plus and minus, the trouble of oil off the coordination, we are a convenient, worry-free.

An automatic car only needs a small amount of brakes when going downhill. Go straight to the gas pedal when going uphill, but don't press too hard.

The automatic transmission must be fueled when going uphill, but it must be very slow when going downhill, and it can be properly braked to maintain a constant speed to prevent the car from rolling over.

Be sure to turn the automatic transmission to the lowest when going downhill and up to avoid a slide and control it well.

The first is not to press the accelerator too hard when going uphill, and to gently press the brakes when going downhill.

When an automatic transmission car is going downhill, it is best to be able to put a low gear on. This makes it possible to use the drivetrain in the lower gear to reduce the speed of the vehicle and ensure safety. In addition, when going downhill, you should use the brakes of the vehicle correctly, and you should not step on the brakes all the time, which will cause the brakes to overheat and the braking effect of the brakes will be affected.

In addition, when going downhill, it is best to choose some potholes to reduce the speed of the car, and if it is safe to do so, you can also go downhill along a z-shaped trajectory, preferably not in a straight line.

When an automatic car goes downhill, it should first be in a low gear. Automatic cars also have low speed gears, so when driving an automatic transmission car downhill, we had better hang on the low speed gear, and then use the transmission of the low speed gear to reduce the speed, reduce the pressure on the braking system, and reduce the occurrence of accidents; Second, use the brakes correctly. When going downhill, the automatic car should not step on the brakes all the time, and the brake pads will be worn out if they are not put back for a long time, and the temperature of the brake pads will be too high due to friction, and the braking effect of the brakes will also drop greatly, so it is best to brake when going downhill, and do not step on the brakes for a long time; Finally, use potholes to slow down.

When going downhill, we can also use potholes on the road to slow down, and try to drive in a zigzag, which is more conducive to reducing speed. <>

Automatic cars also have high speed and low speed gears, and when going downhill, it is best to be able to hang on the low speed gear, so that you can use the low speed to control the speed of the car and ensure safe driving. <>

When going downhill, many people will keep stepping on the brakes, in fact, this will not only wear out the brakes, but also cause the temperature of the brake pads to be too high, which will reduce the braking performance, and the use of point brakes is the most correct braking method. <>

When going downhill, we can also use potholes on the road to slow down, and we can also drive along a z-shaped trajectory while ensuring safety, which is also conducive to reducing speed.

1) Reduce the speed of the vehicle before going downhill so that the vehicle enters the downhill at a slow speed.

2) Shift into the appropriate gear before going downhill, generally you should choose the second or third gear. It is strictly forbidden to change gears after entering the downhill section.

3) In the downhill section, it is strictly forbidden to coast in neutral gear, and it must be put into the appropriate gear, and the speed of the vehicle sliding must be reduced by using the traction of the engine.

4) Use braking with caution on the downhill section, test whether the braking performance is good before going downhill, and if there is a fault, you should go downhill after eliminating the fault. On long downhill slopes, braking can be applied intermittently to effectively control the speed at which the vehicle is descending. Avoid using emergency braking as much as possible, and when emergency braking is necessary, apply the brakes only when the vehicle is in an upright forward position.

5) The steering wheel should be used lightly in the downhill section, and the steering wheel should not be slammed to prevent overturning due to large inertia force, fast speed and improper use of the steering wheel.

6) The distance between vehicles should be kept at least 50 meters. If the slope is too long, the inertia force of each vehicle is very large, and the workshop distance should be increased appropriately.

7) If the downhill is followed by an uphill slope, when approaching the bottom of the slope, you should be prepared to rush the slope and switch into the high-speed gear in time.

It is necessary to hang the low gear first to reduce the pressure on the braking system, and then point the brake, and not step on the brake for a long time, which will cause the temperature of the brake pads to be too high and the braking effect will be weakened.

You can choose D gear, so you can slow down well and keep the brakes on it. Don't choose a neutral gear to save fuel. Doing so may damage the car. Brake failures can also occur.

When going downhill, you can shift the gear to D gear, and step on the brakes to slow down the speed.

There is a difference between automatic transmission and manual transmission, the gearbox will be continuously shifted, and if you go downhill, you can drive normally in the running gear, and there are no special operation requirements.

When going uphill, you should drive in first gear, you should also apply the brakes when driving, so that you can start slowly, and when going downhill, you should control the speed of the car, and you should also maintain first or second gear for driving at a constant speed.

When going downhill, be sure to step on the brakes and go down gently, try to move forward when going uphill, and then step on the accelerator, because only in this way can you walk better and avoid problems.

The car can drive on the accelerator when going uphill, and be sure to brake and drive slowly when going downhill, which is the correct way to drive.

How do you drive an automatic transmission car uphill and downhill? When and how to shift gears? This is the question asked by the questioner.

Before the question, let's review the shifting of automatic transmission vehicles. Automatic transmissions: Shifts are based on the engine speed (engine load) and the speed at which the vehicle is traveling. In L mode and M mode, the gear will not move up Remember, remember to make good use of this feature of the automatic transmission

Automatic uphill: When an automatic transmission car is on the normal ramp section of a general highway, it can use D gear to go uphill. The reason is that we need to keep pressing the accelerator to supply the engine fuel when going uphill in D gear, so that we can do the work and constantly overcome the resistance of the car when going uphill.

If you loosen the throttle on the way uphill, the speed will be reduced, and the automatic transmission vehicle will drop into the next gear and increase the uphill torque according to the reduced speed. If the speed of the vehicle rises during the uphill uphill, the upshift will be performed according to the current speed.

If the automatic transmission car needs to climb a particularly steep slope, it can be climbed in L gear. Generally, the L gear has 1 3 gears, which is called low gear, which has a good low torque and meets the requirements of the uphill slope. On special steep slopes, you can hang a gear suitable for the current slope in advance, and the L gear will have a lock function, which will not cause the vehicle to change gears when going uphill.

If the automatic transmission car has M gear, it is also possible to climb the hill with the first or second gear on the M gear. Automatic descent:

When an automatic transmission car stops at a general highway ramp, it engages D gear and then uses the brakes to go downhill within the specified speed limit. If it's going downhill, you need L or M gear, and it's best to use the engine brakes to control the speed.

When an automatic transmission car is used downhill, especially when using D gear on long downhills, the D gear of the automatic transmission will be increased or subtracted according to the driving time. Exactly in D gear, downhill vehicles will get faster and faster under the acceleration of gravity, so that D gear will shift upwards to accommodate the current speed. After braking and decelerating to control speed, the vehicle in D gear will downshift to accommodate the current speed.

As a result, this will result in frequent shifts in the D-speed gearbox. To avoid this, users in manual mode can switch to manual mode. In hand-based side-motion mode, the transmission will only downshift based on the speed of the vehicle, not upshifts due to high speed.

Manual mode (M) downhill is one of the safest primary modes.

How to drive uphill and downhill in an automatic car? When and how to shift gears? This is the question asked by the questioner.

Before the question, let's review the shifts of automatic cars. The shift of an automatic transmission vehicle accelerates and decelerates the vehicle according to the speed of the engine (engine load) and the driving speed of the vehicle. No upshifts are performed in L mode and M mode.

Remember to always take advantage of this feature of automatic shifting. Automatic uphill transmission: When the automatic transmission takes the regular slope section of the ordinary road, it can use D gear to go uphill.

Why? Because when we are going uphill in D gear, we need to keep pressing the accelerator to supply fuel to the engine, and constantly do a good job of overcoming the vehicle's climbing resistance when going uphill. On the way uphill, when the oil trap door is loose and the speed decreases, the automatic transmission will increase the uphill speed according to the reduced speed to the next gear.

If the speed of the vehicle rises on the way uphill, it will be upgraded to the uphill slope according to the current speed. If you need to climb a special steep slope in an automatic transmission, you can climb uphill in a low gear. The general L gear has 13 gears, called low gears, which are conducive to the low torque demand on the uphill slope.

When climbing special steep slopes, you can hang up a stop suitable for the current slope in advance. The L-gear has a function of locking the stops, so the vehicle does not switch between stops on uphill slopes. If the automatic car has M gear, it can also climb on the sidewalk in 1st or 2nd gear of M gear.

Automatic transmission downhill: When the automatic transmission vehicle descends the general road ramp, use the brake after getting into D gear, and do not exceed the specified speed limit. If you are going downhill, choose L or M gear and use the engine brake to control the speed of the vehicle.

If the automatic car uses D gear downhill, especially long downhill, the D gear of the automatic car will adjust the gear according to the car's condition. That is, the vehicle in D gear downhill is getting faster and faster under the acceleration of gravity, and D gear is increased to adapt to the current speed. Then, after braking and slowing down to control the speed, the D gear is downshifted to accommodate the current speed.

As a result, the transmission in D gear shifts frequently. To avoid this, you can switch to manual mode if you have one. In manual mode, the transmission only downshifts based on the speed of the vehicle, not because of the high speed.

Manual mold car belt type (M) downhill is one of the safest main ways.
