PURPOSE:To set up secure lock up operation by transmitting output inhibition signal for a fixed period of time on the basis of trigger given from Ex-OR circuit at gear shifting. CONSTITUTION:When a shift lever for gear change is operated, shift switches 50, 51 come in operation to put either one of photocouplers 53, 54 in conductive state. Then, one of input sides of Ex-OR circuit 58 is set to L in order to output 'H' voltage to AND circuit 59 as a trigger. Upon receiving this voltage, the second monostable multiplexor 20 outputs H voltage (output inhibition signal) to an invertor 19 for an assigned period. Then, supply of a trigger to the first monostable multiplexor 21 is forcibly interrupted. Thus, the lock up clutch comes in OFF state. |
