Isitronic is the trade name of a robotic mechanical gearbox. This checkpoint combines the convenience of the "machine" and the benefits of "mechanics". This design was developed jointly with LUK and Opel companies, and included in the package of models Opel Zafira, Astra and Corsa.

Easytronik, what is it different from the rest of the gearboxes

In cars with isitronics there is no clutch pedal, and its role is performed by an electromechanical drive. In the design of such a box, two working modes are implemented at once - automatic and semi-automatic. During operation, the electronic unit fully controls the PPC automatically. That is, the PPC behaves like a regular automaton, but the PP operations, and are performed as part of the break of traction.

Device and principle of operation

The ECU control algorithm is made in this sequence:

1. Torque becomes smaller.
2. The clutch is turned off.
3. Selected gear.
4. Synchronization occurs.
5. The transfer is included.
6. Clutch is turned on.
7. Torque becomes more.

When choosing a semi-automatic mode, the speed switch is performed by the driver manually. This mode switches the transmission sequentially using the selector lever. The manual mode switching mode in isitronics is called "Active SELECT" and is a similar type of typotone.

Iitronic, the history of the invention

The high cost and complexity of traditional "automata" is known to all modern drivers. Naturally, the question arose: "Is it possible at the modern level of technological development, there is no possibility to reduce and simplify this design?" This is the opportunity and was found by the engineers of the company Opel, who developed a unique checkpoint, and the transmission, which was based on their new technology, was called "Iitronic".

The idea of \u200b\u200bthis development is pretty simple. If there are debt designs of the manual transmission, then why not equip the CAT data by an automatic control system. However, a problem arose in the control algorithm. If in the classical automatic transmission, all nuances arising in connection with various conditions of load and movement successfully assumes a hydrotransformer, which ensures the smoothness of switching, then in a robotic MCPP hope only to the highest accuracy of feedback, because the adhesion remains, and, accordingly, associated problems. Thus, despite the massive world research, until recently, replacing the work of a person's work of the management algorithm of the robot did not produce any auto manufacturing.

However, engineers of the well-known company Opel were able to solve this problem. Its basis is a "tricky" adaptive algorithm, which has the ability to self-step. The manual transmission itself, while structurally remained the same, only supplemented with three drives - clutch, inclusion of gear and shift rod. The control of the coordinated simultaneous operation of these drives is made by the control unit receiving signals from a plurality of special sensors - throttle, crankshaft revolutions, acceleration, speed and others. As a result, the solution to switch the transfer is made by the "brains" of the checkpoint of isitronics. It is worth noting that it happens very quickly and sufficiently weigly, which makes it possible to actually forget about the main problem of this gearbox - a break of power flow when switching.

Izitronik, why only Opel company uses

To date, Opel actively applies this development to almost all of its models - Zafira, Astra and Corsa. Fiat's autocontracene also did not stay aside. Most other manufacturers of cars prefer classic automatic transmission or variators. This happens for several reasons. First, as a result of power break. Secondly, due to the mechanical "entity" of isitronics, there is a need for quite frequent maintenance. As a result, over time you have to change the clutch. Control the drive of the gearbox and so on. This should be done no more than on the "mechanics", but it is not compared with the classic automatic transparent.

Isitronic, pros and cons

PPC Izitronic is an excellent choice for a car owner who respects comfort, likes to save and used to calmly measured ride. Most likely, such a driver in the process of driving simply will not feel the difference between automatic transmission and isitronized. At the same time, the difference in their price is very noticeable. In addition, operating costs to a large mileage (clutch replacement) at the winner of isitronics will be significantly ahead of the "automatic".

As for motorists who are accustomed to the "torn" ride style and harsh accelerations, when using isitronics, they may face disappointment, since it feels acceleration will not be very pleasant, and repair may well need much earlier than expected.

Tips Profi, how to extend the service life of the transmission box isitronics

First, when switching the transfer it is necessary to release the gas pedal, otherwise the electronics will reset the revolutions, which is why jerks and failures will appear.

Secondly, when stopping, translate the selector lever to the neutral position, which will extend the tightness of the grip.

Thirdly, follow the health of the stop signals, since with the open chain as a result of the blur lamp, the robot cannot find out that the brake pedal is pressed.

Fourth, Opel company categorically prohibits the vehicle in the parking lot with the transmission enabled. A parked car must be left on a neutral with an included parking brake (handbone).

In addition, the first three thousand kilometers is running in, so it is necessary to ride with special accuracy.
