<p>PURPOSE:To prevent the racing of an engine by confirming the continuation of a neutral or parking position signal several times in the case of this signal being outputted by a shift position sensor during travel with a powder clutch in the locked state, and putting the clutch in the current non-applied state only in the case of this signal continues. CONSTITUTION:In the case of a shift position sensor 9 outputting a neutral N or parking P signal during travel with a powder clutch 3 in the locked state, the continuation of this signal is confirmed by repeating a routine several times. When the shift position is changed to advance D or retreat R during this confirmation, the clutch 3 is maintained in the locked state. In the case of the N, P signal disappearing during the confirmation, the shift position sensor 9 is judged to have contact failure due to vibration or the like, and the clutch 3 is maintained in the locked state. When the N, P signal continues, shift operation is judged to have taken place, so that an exciting current from an exciting current driving circuit 10 is stopped to put the clutch 3 in the released state. The racing of an engine can be thereby dissolved.</p> |
