Abstract
A method for detecting a faulty measurement channel on an elastic transmission element in a gearing mechanism, wherein the elastic transmission element has a first strain gauge assembly with multiple first measurement channels. For each measurement channel of the first measurement channels, a plausibility check is carried out using multiple first measurement signals.
Claims14
A method for detecting a faulty measurement channel on an elastic transmission element in a gearing mechanism, the method comprising:
- providing the elastic transmission element having first strain gauge assembly having a plurality of first measurement channels, performing a plausibility check for each of the first measurement channels using a plurality of first measurement signals.
A drive module comprising:
- a gearing mechanism having an elastic transmission element, and
- an evaluation unit having a first strain gauge assembly having a plurality of first measurement channels,
- wherein the evaluation unit is configured to;
- detect a faulty first or, if applicable, second measurement channel by performing a plausibility check for each of the first measurement channels using a plurality of first measurement signals,
- correct the faulty measurement channel using one or more first measurement signals and determine a torque acting on the transmission element using at least one of the corrected measurement channel or one or more remaining measurement channels.
