Abstract
A method for zero-resetting of a device for measuring transmitted torque while a cycle is in motion consists in monitoring a phenomenon or a parameter which is normally variable during normal use of the cycle and which disappears or becomes constant when the driving wheel rotates on free-wheel motion. When the disappearance or the constant character of the phenomenon or parameter thus monitored is observed during a predetermined period of time, one initiates zero-resetting of the detector system or of the measuring system proper of the torque-measuring device. The device for carrying out the method includes on the one hand a monitor for the phenomenon or parameter and on the other hand a control which are operated in dependence on the signal emitted by the monitor and which are then capable of producing action on the detection system or the measuring system in order to reset either of these two systems to zero.
