When most people take a driver's license, they learn to block the car by hand, but they drive it automatically. Therefore, lack of formal training on the basic knowledge of automatic driving, often have some bad habits. Don't underestimate this point. Once the habit-building achievement is very difficult to change, the best way is to develop good habits at the beginning of driving to avoid entering the driving misunderstanding.

Misunderstanding 1: rely on D to block the world

When a lot of people drive an automatic car, they do n’t care about putting the lever in the position of D. No matter what the road conditions are, they are all handled by the D block. This is why people say that driving the automatic car is simple. In fact, people who really know how to drive an automatic car will move the bar up and down at an appropriate time to adapt to different road conditions. Under normal road conditions, we can always drive in D gear. However, when driving on mountain roads, it is necessary to choose an appropriate time to drop to low gear.

If the vehicle speed is too fast, it has exceeded the maximum speed of the gear you want to reduce. At this time, the damage of the downshift to the automatic transmission is very large, and it is easy to burn the friction plates in the transmission. Moreover, many automatic transmissions There is a self-protection mode, this operation is simply impossible to achieve. In this case, you need to use the brake to reduce the speed, and then engage the corresponding gear. In particular, you should pay attention to: using low gear does not want the car to slip faster and faster, instead of slowing down the speed of the fast car, if you want to slow down, use the brake until you think it is slow enough, then lower the gear, use the engine Brake to control vehicle speed.

Misunderstanding 2: Injury to the car with the left foot brake

Many people have the operation of using the left foot to brake. They believe that when the automatic transmission car is opened, the left foot is liberated without the bondage of the clutch, and the right foot operates the throttle and the brake, too tired. Simply use the left foot Come to brake, so the division of labor is more reasonable if you operate a pedal with one foot! And on a relatively large slope, even the automatic transmission is easy to slip backwards, and it is no longer easy to slip when you brake and then refuel.

On the surface, it seems that this statement makes sense, but it is not. Think about when we are driving, except when going up a large slope, how often is the throttle and brake used together? If it is not extreme off-road, this situation is almost non-existent. Have a chance to try, the left foot brake simply can not grasp the strength of the brakes.

Although the left foot brake has also been regarded as an orthodox technology, and I have seen some car manufacturers provide users with training materials, but that was a long time ago. Even if it cannot be said that the left foot brake is the wrong operation method, I think this is not a good method. Before many people have mastered this method, it is easy to become the operation of braking while refueling. Every part of the friction work is subject to wear, especially the clutch friction plate. Such a large pressure is very harmful to it. At the same time, refueling and braking, the transmission and the brake kill each other, this is definitely not a Smart move.

Myth 3: Misuse of temporary parking

Whether a short stop (such as a green light at a crossroad or a traffic jam on the road) waits, whether to use D gear or N gear, this is the most common problem with automatic transmission and the most controversial. In fact, both methods have shortcomings. Of course, the shortcomings of one method will naturally become the advantages of the other method. Let's look at D gear first. The disadvantage is that the engine has to bear a certain load. When the air conditioner is turned on in D gear, the speed will be reduced by two or three hundred revolutions compared to idle speed. , You must step on the brakes, sometimes you ca n’t stop the car with the handle brake, which will increase the chance of accidents. If the right foot is soft for a long time, it may run into the front car; and, the entire engine , The transmission, the axles, the wheels and the brakes are all acting on each other. Obviously, this will aggravate the wear of the friction surfaces of those connected positions.

Looking at the N gear, the disadvantage is that when you drive again, you must re-enter the D gear. Such a first cable (general term for the brake pads and clutch plates in the automatic transmission that lock the planet gears) will naturally be one more Wear, and there will also be a certain impact, which affects the comfort of the ride.
