9.1.2 Constant Traction
A pre-set traction value activates the eddy-current brake immediately which maintains a
constant traction for the duration of the measurement.
The values to be set are oriented on
• the model and size of the test vehicle
• and on the desired inclination angle.
A steady incline (sloping surface) is simulated in this mode. It can be used, for example, to run
the engine of the test vehicle up to operating temperature. The higher the value entered for the
traction the larger the angle of inclination The simulated slope can be driven in any gear or
speed. The eddy current brake effectiveness remains constant at all speeds.
1 Position the vehicle on the dyno and fix it.
2 Call up the menu LOAD SIMULATION and
then the menu point CONSTANT TRACTION
.
The following screen appears:
3 Enter the target value of the traction F-
Target using the digit keys.
4 Use the button <F8 CONTINUE>.
The measurement screen appears.
With 4-wheel drive vehicles the traction target value is divided between front and rear
(depending on the vehicle-specific distribution of forces).
