are cineva timp sa explice pentru cei care n-au auzit niciodata de asa ceva ? http://www.garajul.r...tyle_emoticons/default/crazysanta.gif

[MikeTekRacing]

sistem care:
-intareste suspensia (au amortizoarele alea "smechere")
-schimba sensibilitatea volanului (parca intareste servoul)
-schimba modul de raspuns al pedalei de acceleratie

mai multe detalii poate un posesor de opel (VIPER....) sa ne dea

Advanced chassis: Premiere for IDSPlus with electronic adaptive suspension CDC

A completely new dimension of balance between comfort and active safety can be experienced in the new Astra with the optional, adaptive IDSPlus suspension system and electronic Continuous Damping Control (CDC). This integrated chassis control network (ICC), where the control units and sensors of ESPPlus, ABS and CDC communicate constantly via the high-speed CAN (Controller Area Network) data bus system, is making its premiere in the compact segment. With IDSPlus, Astra drivers can activate a special performance mode by pressing the Sport Switch. This selects suspension settings for the enthusiast-driver, adapts the steering and accelerator response and, with automatic and "Easytronic" transmissions, adjusts the shift points higher up the rpm range.

Jaffar, vezi thread-ul cu suspensia BOSE. IDS e strabunicu�, sa zic asa.

[VIPER]

Nu chiar. Nu are legatura numai cu suspensia, deci nu chiar. Plus ca cea propusa de Bose este deocamdata concept, pe cand IDS+ se foloseste deja de 2 ani, si a ajuns la generatia 2, IDSplus2. Si, din nou, nu se refera numai la suspensie.

[lexus]

Ok.

[jaffar]

vreau si eu un drive test pleeze !

[canan17ro]

Pe scurt si in romaneste - fiecare amortizor este controlat electronic si i se ajusteaza taria cu presiune de gaz in timp real, in functie de suprafata de rulare, conditii atmosferice (ex. vant lateral), forte G (ex. in curba la dreapta amortizoarele de pe stanga se intaresc, la franare cele de pe fata, la accelerare cele de pe spate) - asta e CDC (Continuous Damping Control) parte principala a IDS+. Pe langa astea exista un mod Sport care se activeaza de la un buton de pe bord (pe care evident scrie Sport ) si care intareste foarte tare amortizoarele (preferabil sa se ruleze pe drum perfect asfaltat). Butonul Sport mai scurteaza cursa directiei si o intareste, motorul raspunde mult mai prompt la apasarea pedalei de acceleratie.
IDS+ mai cuprinde : ESP+ (poate frana 3 roti simultan), TC (Traction Control), CBC (Cornering Brake Control), CDC (am zis mai sus), UCL (Understeer Control Logic).

Cam asta e!

Adica nu mai face Astra torque-steer ?
Hmm . Interesting .

[canan17ro]

Face dar mult mai putin.

@Jaffar: tocmai tu ai scapat ne-testat? Io iti fac drive-test, da' numai cu tine in dreapta

"motorul raspunde mult mai prompt la apasarea pedalei de acceleratie"

Adica, de ce ar vrea cineva, vreodata, ca motorul sa nu-i raspunda cat mai prompt cu putinta la apasarea pedalei de acceleratie? Nu asta cautam toti, raspuns cat mai rapid? De ce tre sa apas un buton ptr asa ceva?
Poate am inteles eu gresit.

[canan17ro]

Pentru ca nu poti merge constant cu o masina care ar fi setata in acel fel. Acceleratia este foarte violenta in prima faza iar frana de motor la fel. Esti ba in fata ba in spate si daca nu ai de gand sa mergi sportiv e enervant rau. Asa masina fara sport e o solutie de compromis iar cu sport pedala nu mai are lag-ul specific drive-by-wire.

deci gata, nu mai suport. cind imi aratati careva si mie minunatiile astea ?

intrebare: ai zis ca schimba si "viteza" directiei. cum face asta ?

[canan17ro]

Cred ca scade presiunea in caseta de directie. Cert e ca directia devine mai "grea" si mai precisa.

[jaffar]

mai grea sau mai usoara e una, numarul de ture de la maxim la maxim e alta
am mai vazut la o masina buton de schimbat "taria" directiei, dar nu prea imi dau seama cum functioneste.

[LaScurt]

Cred ca scade presiunea in caseta de directie.

La Astra, servodirectia e hidraulica?

[Dee]

Electro-hidraulica. Ca sa se evite lipsa de feeling specifica directiilor full electric vezi Megane.

[jaffar]

nu e la majoritatea masinilor ?

[Extremero]

Asa masina fara sport e o solutie de compromis iar cu sport pedala nu mai are lag-ul specific drive-by-wire.

Se poate creste viteza de reactie a pedalei de acceleratie si la alte masini [in speta la a mea]?

Ca uite asa mi se face dor de vremea carburatoarelor si a cablurilor de acceleratie. Offf.

[canan17ro]

Nu ai ce sa-i faci din pacate! Ai descris bine sezatia - e de carburator .

Deci ce am obs. legat de directie : pe loc nu e nici o diferenta la cursa dar in mers se simte. Nu stiu cum face. Jaffar tu ar trebui sa stii cum e ca BMW-ul are ActiveSteering care cam tot asta face dar mult mai ponuntat.




Asa arata ei ce face IDS+ :
Acceleratia, amortizorele, directia si pentru easytronic schimba sus in ture. Sunt multe flash-uri despre subiect dar nu se pot copia.

EDIT - apasati pe Sport

Varianta oficiala :

Pressing the Sports button will change the characteristics of the following systems to a Sports mode:

Engine: the engine will respond more spontaneously to accelerator pedal position.
Steering: The steering becomes more direct, thereby improving steering feel.
MTA or AT transmissions: The gearshift times on automatic or MTA transmissions will be shorter and the timings assigned to higher engine speeds. If the cruise control is switched on, this change will not occur.
CDC system: When the Sports program is switched on, damper control will be adapted to a sportier driving style - stiffer chassis tuning.
ESP: Is switched off by pressing the Sports switch for longer.

Continuous Damping Control (CDC)

Continuous Damping Control (CDC) is a continually variable damping system and is a completely new system in this class of vehicle. CDC adapts the damping performance of the vehicle's shock absorbers to the respective driving situations and road surface quality. The CDC system utilises the "Skyhook" operating principle. The aim of the "Skyhook" principle is to keep the body as steady as possible through variable damping, regardless of the condition of the road. For this, the system utilises as a reference point a so-to-speak imaginary virtual plane (e.g. the sky above the vehicle) which is stored as a computing model in the CDC control unit. The aim is to keep vehicle body movements as horizontal as possible with this plane. All vertical movements are compensated for as much as possible by targeted actuation of the individual shock absorbers. These actions are carried out in a matter of milliseconds.

Shock absorbers

The shock absorbers can be steplessly adjusted electronically. The CDC system continually monitors the movements of the wheels and vehicle and immediately changes the damping of each individual shock absorber. The chassis is thereby tuned in an optimum fashion to the respective driving situation. As a result, the Astra-H offers excellent ride comfort without compromising on safety reserves. Braking performance on uneven roads is also optimised and wear of the shock absorbers is compensated for up to a certain limit.

Shock absorber adjustment is calculated by a control unit and is based on the following information:

Road conditions
Vehicle speed
Brake actuation
Wheel acceleration
Steering movement
Vehicle's angle of inclination in the longitudinal and lateral direction (lift, roll, pitch)
Lateral acceleration (yaw rate)
Switch position - Normal or Sports driving style
ESP signal for damping correction
