Effective car acceleration – Car driving

Effective car acceleration

The main mistake is the slipping of the drive wheels (when the car is stationary, and the drive wheels rotate). If on any surface, whether asphalt or ice, you do not allow it, then consider that you already own a piece of skill. How to learn this?

On a flat road, preferably on an unloaded car (with a manual transmission), at idle, turn 1st gear and start the first movement without pressing the accelerator pedal at all, i.e. working only with the clutch pedal. When the car starts moving (idle speed), stop it by “pressing the clutch” and repeat again. It turned out? Try the same thing, but using 2nd gear. Do not overdo it! Two or three times happened – enough!

At such a start of movement, your drive wheels will not slip – there will not be enough engine power and, in extreme cases, it will simply stall. In ordinary life, we, of course, will not start the movement like this, except in rare cases when it’s very slippery. The conclusion is simple: the lower the engine speed at the start of movement, the greater the likelihood that there will be no slipping! In order to make the car easier to start moving, the front wheels must be set strictly straight!

But how can one accelerate quickly on slippery ice? More about this below.

The beginning of the movement or “acceleration”, to put it simply. Many will even name the necessary terms — weather tires, a powerful motor — and they will be right, but only partially. What else is important to know, and most importantly – to be able to?

We dare to remind you that the main mistake is, firstly, the driving wheels of your car skidding in place. The car is not located in a straight line with respect to the direction of movement, and the front wheels are turned (do not stand strictly straight). This is the second. How to learn to feel the beginning of slipping? A simple exercise, with the beginning of movement without “gas”, we think, did not cause great difficulties.

Lesson two. Subtle sensations

The car stands with the engine running on level ground. Engage I gear and slowly release the clutch pedal. There will come a moment when your car, before you start moving, as if “straining”. Pay attention to this, try to feel it.!

After the moment of “tension”, if you release the clutch a little more, movement will begin. But, as soon as the car makes a rush to move, and the wheels turn slightly, press the clutch exactly enough so that it stops and the “tension” is eliminated. Performing this non-stop, you will swing the car on the spot. The smaller the amplitude, the better! Ideally – the tires are in place, and the rim barely noticeably turns back and forth.

Exercise can be performed anytime, anywhere, it is absolutely safe. Now you know exactly how your grip works and in what range. By the way, all of the above can be done on a car with automatic transmission.

The next stage of training and sensations. The car stands still, you increase the engine speed to any value (for example, 2.500 rpm.) And hold it for a long time. It is better to do this by looking at the instrument – the tachometer, if there is, and if not, then by ear. Your task, by turning on I gear, start moving while holding the engine speed that you set before. From the beginning to the end of the exercise, the turns are the same – they do not fall and do not rise. Doing it all the better on the site, where there is no movement of cars and pedestrians. At the first attempts, it is better to look at the tachometer, again, if there is one. You need to start with a slight increase in speed and, as you complete it, complicate the task by increasing them. It is important to pay attention to the speed of releasing the clutch pedal, namely: try to do this as soon as possible.

If everything is done absolutely correctly, then the car accelerates quickly and without slipping, and the higher the engine speed that you hold, the faster. There comes a time when the execution becomes impossible due to the occurrence of slippage. Most often, this means that for a given pavement you have crossed the line and the engine speed is too high. The conclusion is simple: the higher the coefficient of adhesion, the greater the speed for quick acceleration we can afford! Performing acceleration in this way, you begin to catch the beginning of slipping, if you make a mistake – this is the uniqueness of the exercise.

Acceleration tricks and the start of movement

1. If you need to win the “start”, then the maximum form of your readiness for this is when the engine speed is chosen correctly, the front wheels are straight, and the car swings slightly in place (see Exercise above);

2. At the beginning of the movement, the center of gravity of the vehicle shifts back, loading the rear wheels. If a car with rear-wheel drive, this increases the acceleration efficiency, and if with a front-wheel drive it lowers (front, driving wheels are loaded). Using the rocking technique in place, i.e. moving the car back and forth, you and the center of gravity move back and forth. Using its movement (depending on the type of drive of your car), you can increase the efficiency of the starting moment, and even on very slippery roads start moving without slipping.

What is an extreme driving school?

Over the past year, as a result of an accident in Russia, about 35 thousand people died, approximately 270 thousand were seriously injured.

What follows from this? And the fact that most drivers either can not figure out their car, or simply can not navigate in a particular situation on the road.

What to do? How to reduce the number of accidents, and therefore the number of victims, sometimes completely stupid accident?

We will not say that before you get behind the wheel, it’s worth looking at a driving school at least a couple of times and don’t start turning the “steering wheel” with the rights you just bought and a friend explaining for 15 minutes what the gas and brake pedals are. Well it is clear.

But how to learn to behave in extreme situations on the road? This will not be taught to you in a regular driving school, and the prospect of learning it from your own skin, I think, does not seduce anyone, and it is not a fact that you will learn this when you are in an accident.

And there is a way out! As soon as you have received any driving skills in one of the driving schools, run and apply to the so-called “Extreme Driving School”. True, there are not such establishments in all corners of Russia..

And what is the “Extreme Driving School”? “SHEV” is the same driving school, only of a higher level. People come to it who already have a driver’s license, but who seek to learn to act confidently in extreme situations on the road and not lose control over these situations.

“SHEV” has special platforms, various types of cars and professional instructors that will help you master all the skills of a super-driver.

When filling out an application, you will need to determine your level of “self-knowledge and skills”, instructors will also help you with this. Only after that you will be able to start classes on a certain course. There are basically three such courses: Beginner, Midi and eXtrime.

Novice is a course for people who have just gained rights and still cannot confidently move around the city streets.

“Midi” is a course for those drivers who already have driving experience, but who are afraid to go to the streets with heavy traffic.

But the course “eXtrime” is intended for people with a rich driving experience and freely tacking on the roads.

In the process of training, a professional instructor will teach you how to act correctly in various extreme situations of any complexity: from ice to a difficult emergency situation. All situations will be reproduced at special sites, there will be an opportunity to visit the same situation, but on different machines.

Initially, for example, in a situation with ice, you will observe the whole process, sitting in the passenger seat, your personal instructor will be driving. The next attempt will be yours. Situations will be complicated with every lesson..

As a result, by the end of the course you can not only improve your skills, but also avoid most accidents. And if you find yourself in an unpleasant situation, you can not let everything go by its own accord, but quite professionally get out of it.

To go submit documents to “SHEV” or not, now it depends only on you.

In turn, I hope that you make the right choice. Well, good luck on the road!

What is the turning apex, and how is it important for everyday driving 10

What is the turning apex, and how is it important for everyday driving

What is the turning apex, and how is it important for everyday driving

What is an apex, and why this knowledge can be useful to every driver in everyday car life?

The mythical apex is what every rider in every turn must get into, according to each commentator, and where the car should bring him to, according to every car journalist. One cannot miss him, one cannot be mistaken with him, and it is not so easy to find him..

What is apex?

From a purely geometric point of view, the apex is the pivot point, that is, the point where the wheels on the side the car is turning will touch the inner curb or dividing line of the road. If you imagine a turn in the form of a hill, it will be a geometric peak, which is why the apex is called the turn peak. It can also be described as the point at which the car moves most slowly, finishes turning and begins to straighten the path, and at which the entrance to the turn conditionally passes into the exit from it.

However, the geometric apex is not the only important point in the turn: from the point of view of racing, it does not always lie on the best trajectory of the turn. There, besides him, two more apexes rule: early and late.

What is early and late apex?

The early apex is a point lying on the inner side of the road or the dividing strip of the road to the geometric apex – in this case, it turns out that the car slightly “cuts off” the path relative to the path that includes the geometric apex, and then leaves the turn wider than it. Late apex is the opposite situation when a car enters a bend wider than a path containing a geometric apex, touching the inside of the bend after it, and leaves the bend along a narrower arc.

Speaking about all three types of apex, it is worthwhile to understand that for each particular turn the ideal apex can differ from all three types, gravitating to one of them: after all, when passing a turn, there can be different tasks – for example, get through it as quickly as possible or cut it as fast as possible trajectory.

What is the turning apex, and how is it important for everyday driving 11

In terms of driving, the difference between early and late apex is important. When passing a turn along a trajectory with an early apex, the speed at the entrance to the turn will be higher and the path traveled will be shorter, but in order to keep within the turn and not fly out at the exit, you will have to slow down more actively and more actively turn the steering wheel after the apex, as well as exit the turn more slowly and over a wider path. In the case of the late apex, everything is exactly the opposite: at the entrance, the arc will be wider, and the speed before the apex will be lower, but at the exit, after the apex, it will be easier to fit into the turn and, using its entire width, exit it at a higher speed. Since it is precisely the fast and controlled exit from the turn that is important for the successful passage of the route, the late apex is considered more correct. The early apex is often considered a mistake, as it forces the steering wheel to turn in a corner, risking the stability of the car and losing speed. More correct and safer is the passage when, after the apex, the driver begins to straighten the path.

What does it mean to “miss the apex”?

To miss the apex usually means not to fall into the very optimal trajectory on which the desired apex for the task lies. For example, wanting to take a turn along a trajectory with a late apex, turn the steering wheel too early and thereby lose speed at the exit.

How this knowledge can be useful in everyday life?

The theory of cornering is one of the fundamental difficulties of car racing. But we will not delve into the theory with different combinations of road configurations after a turn and consider a conventional public road, where there is only one turn, it has a simple shape, and getting out of it is not complicated.

In such everyday driving, it is important and useful to understand what the “correct” late apex is. Like races, each turn here is still unique, and the way it is better passed depends on many factors, such as the type of road surface, type of car drive, season, road moisture, and more. However, the late apex principle works at permitted speeds almost universally.

The essence of safer cornering in everyday life is precisely the choice of a trajectory with a late apex: it is worth braking and choosing the optimal speed before the turn, enter it wider, pass it through the late apex and exit along a narrower and, therefore, safe trajectory without risk meet the turn and fly to the side of the road or oncoming lane. That is, under normal road conditions, the same principle works that we described as correct in the first paragraph: for safe cornering, you need to choose a path in which you do not need to brake and turn the steering wheel after the apex to fit into the turn – but vice versa it will be possible to slightly add gas and begin to straighten the front wheels.

What is best to sing while driving

Still not singing while driving? Maybe you should start doing this. The most important thing is to choose the right composition.

It is generally believed that music in the car is a distraction from driving. This is not necessarily the case. According to the British company Chroma, if you sing while driving, music can help cheer up or, conversely, relax.

“Our research has shown that singing significantly improves the psychological state and physical well-being, because it involves the neurochemical systems of the body responsible for praise, motivation, pleasure and stress,” said Daniel Thomas, Chroma director. “If you sing while driving, your senses come into motion, and the diaphragm starts to work and saturates the brain with oxygen.Thanks to this, chemical processes begin in the body that positively affect your psychological state, and at the same time fucking you, “he adds.

At the same time, Thomas makes a reservation that, of course, singing alone cannot be the answer to all questions. But sometimes it’s better to turn on the music, and start to sing along if you need to relax or, conversely, concentrate. Therefore, drivers are advised to have a playlist with their favorite songs on hand..

“Other academic studies show that even music that sounds just in the background has a positive effect. For example, in classrooms. It improves attention, mental abilities, memory and concentration. That is, the very qualities that you need when driving while driving long distances, “says Daniel Thomas.

So which songs are perfect for driving? Chroma has compiled a list of several tracks. So, if you have a long road ahead, then Tracey Chapman’s Fast Car composition is best suited, if you sing while driving. And if, on the contrary, you want to relax, then the best option is to listen to Moby’s Memory Gospel.

Extreme Driving Lesson # 4 – One-Hand Speed ​​Steering

Extreme driving lesson number 4 - One-handed taxiing - Extreme driving - Car driving - A variety of tips for car enthusiasts - Everything for a car in St. Petersburg 20

A professionally trained driver is required to master the steering technique with one hand, especially the left one, since to overcome some critical situations it is necessary to simultaneously shift gears or turn on the parking brake for a while to lock the rear wheels of the car. In addition, one-handed steering increases safety during high-speed driving and difficult reverse maneuvering, as it allows you to expand the rear view sector by turning the body 90 ° to the right.

The technique of circular taxiing with one hand has the following features (positions 1-6 in the upper figure). The initial position of the hand is on the number ’12’ (by analogy with the dial of the watch). After turning the steering wheel to the position of the hand on the number ‘8’ or ‘4’ (depending on the direction of rotation), the driver intercepts the steering wheel in the lower sector by rolling over the back of the hand. This method allows, without losing contact with the steering wheel, to rotate the brush 180 ° to move from thrust down to thrust up.

On vehicles with a horizontal steering wheel (buses, some trucks), circular steering is performed by rolling through the palm of your hand.

In some critical situations, when the car is skidded and rotated, the first revolution is best done with the left hand, and with the right hand, engage the lower gear. One-handed steering will help you more safely maneuver in reverse, because by turning the hull, you will increase the field of view. The main thing is to learn hand rolling in the lower sector. This technique allows you to maintain contact with the steering wheel while rotating..

Of course, performing a roll does not create ideal conditions for controlling the steering wheel in the lower sector, since slippage of the hand is possible. But still, this is much better than a complete loss of contact. To provide greater security of reception and to reduce 1 of its time allows jerkiness of taxiing. This method is necessary so that the roll occurs during inertial rotation of the steering wheel, since due to insufficient contact of the hand with the steering wheel, the possibility of maximum traction is excluded.

One-handed steering is an element of some of the finest tricks. The techniques and methods for their implementation are as follows:

  • stabilization of the car during critical drift – anti-skid is provided by high-speed taxiing with two hands, but the first revolution (360 ° rotation) is desirable to be performed with one hand, since this technique is faster due to fewer interceptions;
  • high-speed turn of the car through 180 ° – simultaneously with taxiing, the driver turns the parking brake on and off with the right hand, thereby achieving a sliding rear axle and, as a result, rotation of the car;
  • stabilization of the car when rotating 360 ° – taxiing with one hand is used twice. First, for a 180 ° turn (see the previous trick), and then for a ‘turn’ of the car by rotating around the rear wheels (‘police turn’).

One-handed steering is most often combined with two-handed steering and allows stabilization of the vehicle in situations involving loss of stability.
