Abstract

PURPOSE: To detect belt slips accurately without fail at low costs by comparing directly the signals synchronizing with the engine rotation and those picked out of the dynamo winding and detecting the slip occurrence rate with respect to the unit rotation of the engine.
CONSTITUTION: An output signal a is picked out of an alternating current dynamo 1 and added to a counter 7 through a wave form rectifying circuit 2. An ignition signal c is picked out of an ignition coil 3 and added to a frequency dividing circuit 6 through another wave form recifying circuit 5. The outputs of the frequency dividing circuit 6 and the counter 7 are added to a flip flop 8 so as to control a transistor 11 through an integral circuit 9 and a comparator 10. When the slip rate surpass the to tolerant value, a lamp 12 is lighted.
