Testing the haptic response

in vehicle controls

Torque/angle readings are checked continuously during cyclical testing of motor vehicle controls to assess their haptic response.

Torque/angle measurement

on vehicle dashboard controls

Precision torque sensor model 8661
  • Non-contact transmission
  • Torque measurement < 0.05 Nm
  • Angle resolution 0.0885 °
DIGIFORCE® 9307
  • Comprehensive process monitoring
  • High sampling rate
  • Measurement accuracy of up to 0.05 %

Task

Das haptische Verhalten von Drehschaltern soll anhand des Drehmoments / Drehwinkels gemessen werden. When monitoring the haptic response of a rotary switch, it is important to measure precisely the torque that must be applied (adjustment force required > proprioceptive sensation > tactile sensation). 

Specific Requirement

Sehr kleines Nenndrehmoment durch geringe Betätigungskräfte. Feine Winkelauflösung, um feine Rastpunkte des Drehschalters abbilden zu können. 

solution

The precision torque sensor model 8661 can be used to measure reproducibly and extremely accurately ultra-low torques over a defined angle range during forward and return movement. Durch die Verwendung des Drehmomentsensors Typ 8661 wird außerdem der konstruktive Ausbau verringert, da kein zusätzlicher Drehwinkelsensor erforderlich ist. Ausgewertet wird das haptische Verhalten der Drehschalter mit dem DIGIFORCE® 9307 anhand des Drehmoment-/Drehwinkelverlaufes.
