When driving an automatic transmission car, can I switch gears at will, and do I need to step on the

There are more and more car functions, and many configurations and functions are not very good at using them, for example, there are so many buttons on the center control panel, many people don't know the use of each button, at most they can turn on the radio and listen to songs, and other convenience functions will not be used. For gearing, a lot of functions have also been added, with manual integration, there are also various driving modes, and many people don't know how to use it. Generally, only two gears are used, forward to hang D gear, backward to hang R gear, such as M gear, S gear, and even N gear are rarely used.

Today we're going to talk about some operations about automatic gear mounting.

You can hang D gear for normal driving, so can you switch gears at will while driving? You can switch between D gear and S gear or M gear at will, you don't need to step on the brakes, and you don't even need to release the accelerator, you can just switch back and forth. If the driving is normal, why change gears?

Let's take a look at the S gear first, the S gear is a sport mode, in fact, it is not much different from the D gear, but it will delay the timing of the shift. Assuming that the D gear will be upshifted at 2000 rpm, and the S gear should be 2500 rpm, always maintaining a low gear and high speed, so that the torque output of the engine is greater and the car is more powerful, which is generally used when overtaking or wanting to start quickly. If you want to overtake, switch from D gear to M gear to speed up the overtaking, and the car will be more responsive.

If you don't understand, you can think of it this way, assuming that at the same speed, the 6th gear 2000 rpm and the 4th gear 2500 rpm acceleration ratio, it must be the 4th gear 2500 rpm faster.

The manual car has M gear, which is a manual mode, which needs to be manually added and reduced, and it can also be hung directly from D to M while driving. Some cars do not have the letter M written on them, but they have plus and minus signs, and this place is also in manual mode. A push on the shift knob in the direction of the plus sign is to go up one gear, and a push in the direction of the minus sign is to go down a gear.

After D to M, the gearbox will automatically select a reasonable gear according to the current speed, and then it will be controlled by the driver, so there is no need to worry about sudden gear changes, the gears will be out of order, causing the vehicle to suddenly slow down or accelerate, and will not have a bad impact on the gearbox.

When should I hang the M gear? If you experience the feeling of controlling the gear, you can use M gear like a manual transmission, but in fact, it is more used when going up and down a large slope. If the ramp is large, use M gear to lock in a low-speed gear, such as first or second gear, when the gear ratio is relatively large, and the vehicle climbs more easily.

The downhill gear is also low-speed, which can effectively use the engine's braking to control the speed, so it will not drive faster and faster, and it is safer to drive.

Switch gears while driving, and do not engage R and P gears, which will damage the gearbox. Both P and R gears require you to apply the brakes and press and hold the gear lock switch on the shift knob. Any gear that can be put in by doing so cannot be switched while driving, and the car must be parked to change before it can be changed.

This is to protect the gearbox and make it a little more troublesome for the driver to gear up in case it is misplaced.

The automatic transmission car can not switch gears at will during driving, especially can not switch to neutral or parking gear, which will cause damage to the gearbox, but in the process of driving, you can switch from the driving version to the sports version, or the manual mode of manual integration, and you do not need to step on the brake and loosen the accelerator when switching.

You can switch gears at will, you don't need to step on the brakes and release the throttle, but don't cut into reverse gear to avoid damaging the gearbox.

No, because as long as the automatic car is in the forward gear, you just need to step on the accelerator and brake, and you will adjust the gear according to your speed, and the automatic transmission is so simple, unlike the manual transmission, the gear shift has to speed up and decelerate.

It is best not to switch gears at will during the automatic transmission car, which may damage the gearbox, and you need to step on the brake and loosen the accelerator to stop the car slowly.

I think you can change gears at will, and you don't have to hit the brakes, because the automatic transmission automatically shifts gears according to the speed of the car, so you can adjust the gears just by adjusting the speed.

You can shift gears, you don't need to step on the brakes, and the vehicle is actually moving, which means that the unit is in low gear, and the shift at this time is nothing more than switching to S gear or M gear.

I don't think so, because the automatic transmission only has a D gear, so there is no need to apply the brakes either.

If the brake and accelerator are pressed at the same time in the automatic transmission, the situation is that you can find that the rear wheels are spinning in place, and they will still wear out to the engine (the manual transmission will not start).

If you press the brake and accelerator together while driving, the car will still stop as usual, but the car will nod forward sharply and then stop immediately, similar to the usual sudden braking. This is because most cars have a brake priority system.

If the brake priority system detects that the driver intends to brake, but the brakes are not successful, it will automatically switch the engine to idle to prevent the car from continuing to rush forward. When driving, you should pay attention, see farther, generally observe 150 meters away, see the dynamics of the vehicle in front and whether there are intersections and schools in front, slow down in advance, and try to avoid sudden braking.

Pressing the accelerator and brake at the same time will cause the engine to emit black smoke, which will burn out the engine for a little longer.

If it's in neutral, of course, the car won't go, and the engine roars.

If you are in gear: the manual transmission car depends on the number of gears, the high-end will turn off, and the low-gear brake will not be able to hold. If the horsepower is also enough, the braking performance is enough, the engine overheats and burns or the clutch slips until it burns out.

Automatic transmissions can cause the transmission oil to heat up dramatically.

Automatic: Engage in D gear, press the brake with your left foot, and press the accelerator with your right foot to the end. When the engine speed is stable, the brakes are released, and the car ejects and starts. It's cool, but it's damaging to the gearbox.

<> "Is it to step on the brakes or loosen the accelerator when decelerating in an automatic transmission?"

Many Qixin car owners often drive manual transmission vehicles due to key tremors, so when they occasionally drive an automatic transmission vehicle, they may not know how to slow down the automatic transmission vehicle. So does the automatic transmission car slow down by pressing the brakes or loosening the accelerator?

Under normal circumstances, the automatic transmission vehicle needs to slowly release the car accelerator first, and then slowly press the brake pedal of the car, at this time the speed of the automatic transmission vehicle will slow down.

If you need to stop when driving an automatic transmission vehicle, the owner needs to drive the automatic transmission vehicle to the designated parking space, and then step on the car brake, directly hang the automatic transmission vehicle on the n gear, you can pull up the automatic transmission vehicle handbrake, and then release the foot brake to turn off, after the automatic transmission vehicle is turned off, the owner needs to push the vehicle's gear into the P gear, and then pull out the key of the automatic transmission car.

When the owner drives an automatic transmission vehicle, it is actually similar to driving a manual transmission vehicle, and the automatic transmission vehicle often does not need the owner to manually change gears during driving, so the automatic transmission vehicle does not need to step on the clutch one more step to slow down. Quiet Wheel.

Automatic transmission is in this state and does not need to apply the brakes. First of all, since the vehicle is moving, it means that the gear is in D gear. Shifting gears at this point is nothing more than switching to S or M.

Automatic transmission vehicles are not allowed to switch to N, P, and R gears while driving. As for the specific reason, I will not go into detail here, and interested friends can go to the Internet to check the information on their own.

Switching to S gear or M gear, the gearbox will automatically match the gear according to the vehicle's current speed, rpm and other factors. The owner only needs to be responsible for the gear, and the rest is handed over to the vehicle's driving computer.

However, there are the following special circumstances: 1. The gear enters the R gear; 2. The gear leaves from the P gear; 3. The gear enters the P gear. In the above three cases, not only must the brakes be pressed, but also the lock button on the gear knob must be pressed to engage the gear.

The locking button, also known as the gear lock, is located on the side of the top of the gear knob. Examples of practical operations:

R gear to P gear, need to press; P gear to R gear, you need to press; R gear to D gear, no need to press; D to N, no need to press.

It can be understood in this way: when entering a gear that may cause a reverse impact on the transmission closed old box, it will be locked, and the lock button must be pressed to unlock when changing gears.

You don't need to release the throttle for acceleration, and you don't need to release the throttle until you decelerate.

There are 2 concepts for automatic shifting.

1. Manual shift to change the operating mode. Examples: Changing from P to D, etc.

2. Change the gear shift of the reducer reduction ratio during the march.

For the first type of shift, it is necessary to press the brakes to carry out, otherwise it will be dangerous; For the second type of shifting, it is the car computer that automatically operates according to the actual situation. As for the "loose throttle shift" is a common method for experienced drivers, it can reduce fuel consumption when used properly, and it is not a shift as soon as the throttle is released.

Precautions for controlling the throttle.

1. Relax the clutch and step on the accelerator closely, and act quickly.

2. When stepping on the accelerator pedal, the force should be soft, so that the pedal is gently lifted.

3. The gear should be selected appropriately, so that the engine runs at medium speed and large throttle most of the time to save fuel.

4. Before the car stops and turns off, the accelerator pedal should be released first, and the empty accelerator pedal should not be slammed.

If the accelerator and brake of the car are stepped on together, different cars will behave differently, but it is best not to do this for family cars, which is related to the safety of the owner and car maintenance

1. Brake and accelerator pedal, generally speaking, will increase vehicle fuel consumption, wear brake discs, etc., but at different speeds and road conditions, it may also lead to sudden deviation of the imitation vehicle, causing safety threats;

2. It is normal to step on the accelerator and step on the car to "scratch the tire" in situ according to everyone's understanding, but in the actual situation, stepping on the accelerator and braking at the same time may not achieve the result of "scratching the tire" in situ, because there are prerequisites for achieving this effect;

3. If your car is a front-mounted Wang Hezheng front-wheel drive car can not be realized, this condition also restricts most cars, ordinary cars are front-wheel drive cars, four-wheel drive can not be realized, only rear-wheel drive cars can be realized. Brake throttle at the same time - brake priority systemMany car owners have heard of the brake priority system, this technology is to maximize the protection of passenger safety when the driver makes a wrong judgment, most of these situations appear in driving;

4. Brake priority system refers to a system that allows the driver to stop the car by pressing the brake pedal when he presses the accelerator pedal and the accelerator pedal is fully open (that is, the accelerator pedal is pressed to the end), that is to say, the brake priority system will automatically switch the engine to idle when it detects that the driver is unsuccessful in trying to implement braking.

Millions of car purchase subsidies.
