ABSTRACT:
The invention relates to a method for preventing at a vehicle gearbox selection of an operationally erroneous gear in the absence of a gear change regulating speed signal. The absence of the gear change regulating signal is detected by a fault detection circuit or by a fault detection routine, which thereby sends an output signal to an operative circuit or the like. The operative circuit ensures that erroneous gear selection is prevented and/or triggers a fault indication.
With the intention of ensuring that a fault already existing when the vehicle starts can be detected, the invention is essentially distinguished in that during the fault detection routine it is determined whether the engine is running, whether a forward gear is engaged, the clutch is engaged, and whether and with these conditions extant whether the speed has attained a given minimum speed within a predetermined time. If said minimum speed is not attained, an output signal is sent to the operative circuit which presents an erroneous gear selection and/or triggers a fault indication.
