Topic: What for actually it is necessary (many beeches.)
When I was silly and young is yet familiar with , I thought that this such adaptation which switches transmissions and "squeezes out coupling" in an automatic mode. Then I did a bit of traveling on and understood that I deeply was mistaken. Actually, the principal organ of control of the car, which behavior cardinally changes at appearance is a pedal of gas. Here let's take any petrol (well it is possible also diesel) the average car with a manual transmission, and think, than controls the gas pedal? More or less technically the right answer consists that it changes an amount of the fuel arriving in the engine, and , through regulation of an amount of arriving air. But you it is serious?? What, somebody, pushing gas in a floor at driving on the car, pushing a gas pedal thinks "here now leads to discovery of the throttle dampfer on an inlet collector, what in turn allows the engine to consume the greatest possible amount of fuel, what considering current turns of the engine gives 70 h.p. of capacity what leads to magnification of turns of its rotation, what in turn leads to a dial-up of speed of the car with acceleration so much that g"? I am assured, at daily driving so anybody (or nearly so anybody, except for the mechanics at present adjusting a turbo-supercharging by the machine of the client) does not think. All think about the same, but in a little simplified type "here now pushing a pedal leads to car acceleration". Also it is finite, in most cases such simplification works. These are the most typical and economic (harmless) scenarios of relocation for a car in a mode of 2-3 thousand turns and a gear change on reaching these boundaries. The brain works simply: pushed gas - went. Engine turns grew too strongly - switched upwards. Threw gas - were decelerated. Turns too low - switched downwards. All well and only sadden an iridescent pattern of universal happiness and slowness, breaking from traffic lights with squeal of rubber and we howl the engine somewhere near to a cut-off. However here there is a big dirty trick because actually all it works absolutely on another how I wrote in the first paragraph about "the engine can consume the greatest possible amount of fuel". And what the machine is dispersed proportionally to pushing gas is an illusion as acceleration is proportional to pushing only in very narrow range of values of this pushing, because that? Correctly, engine turns. The engine does not consume on 2000 turns as much some gasoline, how many on 5000. But thus here these all maximum capacities and accelerations to 100 for 10 for budgetary cars - they on such turns, since 4000 and above. But nobody goes by such turns permanently as it , is uneconomical . Therefore more or less skilled driver if needed quickly to be dispersed on includes a hill-climbing gear, and to teapots in driving schools knock "before overtaking include 3 transmission", i.e. to use all capacity of the car it is necessary to push not simply gas, but also correctly to select transmission to a check point. (Here it would be possible to arrange lyrical digression about on the routes, happened that not so skilled or tired driver irregularly estimated position on road, quitted on overtaking and was not in time. Because, when he understood that is not in time, it is reflex indented a gas pedal into a floor, but the car as gathered slowly speed on 5 to transmission, and continued it to do before the collision. And business was at all in a lack of horsepowers. But, I will not be about it) In what all it results? To that at control of machine with to the driver not simply it is necessary to make any additional motions by feet and hands. It just a small problem. Even at driving in cork on small speed it results only in training of certain muscles and does not strain a brain. The present problem consists that a gas pedal loses the intuitively clear for the normal user (not the sportsman and not the mechanic) assignment - to control car acceleration. All the same to force a pedal to do something close to it, the driver should hold in mind additional parameter - current turns of the engine, or that is even worse, two parameters - current speed and current switched on transmission. It most of all baffles me as the person who is engaged UX and user interfaces a little. Developers of the interface of the user speak - to force this vehicle set in motion by magic, to go faster, insufficiently simply to press on these crystal full-spheres more strongly - it is necessary to be convinced even of the correct position of stars and to shift a magic amulet in one of 5 tanks (if you will shift in wrong, all blows up). What the hell? Same magic! I simply want, that the vehicle went faster at my desire, what for to me the nobility about what that there amulets and tanks turns and current transmission? So, summarizing. is not not to switch a hand of transmission and not to squeeze out coupling. More truly, and for this purpose too, but it not its principal bonus. Its principal effect - that car acceleration starts to be proportional to pushing a gas pedal. As soon as the driver does not accept acceleration on current transmission, it continues to push gas - switches downwards and still downwards and so to - before transmission minimum accessible at present. As gives that effect - the more pushed, the went faster. That allows to discharge a brain from in it of current switched on transmission, speed and all other parameters like a moon phase. It is not necessary to think before manoeuvre and to include reduced - you simply you speak "I want to overtake as fast as possible this truck" and the machine itself selects it on what transmission is better to make. How much pushed gas - so the machine and goes within the limits of the possibilities. It is very convenient, actually.
