Display adaptation data in the report
 |
In order to achieve optimal shifting quality, the principle of adaptive pressure control is used in the DIWA.5 transmission. It allows the control unit to largely compensate for individual manufacturing tolerances and ageing conditions which may reduce the shifting quality. In short: The transmission software is optimized to low wear and high shifting comfort. The ECU report displays all correction values of adaptation. For further information, please see:
Adaptation, operational principle.

Adaptation data must be deleted after maintenance work on the DIWA.5 transmission. |

How to evaluate the adaptation data displayed:
Shifting adaptation Engine torque classes
0 1 2 3 4 5 6 7 Shifting adaptation PA correction [bar] 1-2 shift This display shows correction values for the initial pressure PA, split up into the individual upshifts / downshifts and the engine torque classes. 2-1 shift 2-3 shift 3-2 shift 3-4 shift 4-3 shift Shifting adaptation PR correction [bar] 1-2 shift This display shows correction values for the control pressure PR, split up into the individual upshifts / downshifts and the engine torque classes. 2-1 shift 2-3 shift 3-2 shift 3-4 shift 4-3 shift Shifting adaptation, adaptation counter 1-2 shift This display shows the individual adaptation counters, split up into the individual upshifts / downshifts and the engine torque classes. If the counter reading is <5, adaptation of this correction value is still in the coarse adjustment phase. If the counter reading is = 5, adaptation of this correction value is in the fine adjustment phase. 2-1 shift 2-3 shift 3-2 shift 3-4 shift 4-3 shift Pressure curve Downshift 3-2 Downshift 4-3
Braking adaptation Speed classes
0 1 2 3 4 5 6 7 Braking adaptation PA correction [bar] This display shows the individual correction values for the initial pressure PA, split up into the individual speed classes. Braking adaptation PR correction [bar] This display shows the individual correction values for the control pressure PR, split up into the individual speed classes. Braking adaptation, adaptation counter BR This display shows the individual braking adaptation counters, split up into the individual speed classes. If the counter reading is <5, adaptation of this correction value is still in the coarse adjustment phase. If the counter reading is = 5, adaptation of this correction value is in the fine adjustment phase. Transmission slip [rpm] Retarder 1st gear 2nd gear 3rd gear 4th gear Adaptation experimental values of the Voith customer service:
The following standard values can be used as reasonable maximum limits for adaptation. Upshifts at full load and downshifts at zero load are examined here. 1-2 shift L5 + L6 maximum + 1bar 2-3 shift L5 + L6 maximum + 1bar 3-4 shift L5 + L6 maximum + 1bar Downshift 4-3 L0 maximum +1bar Downshift 3-2 L0 maximum +1bar
