Abstract
PURPOSE: To release the control circuit for the automobile speed control unit for automobiles with a given safe running condition, even if the release switch is faulty.
CONSTITUTION: The output from the automobile speed detection section 1 is converted into a DC voltage in proportional to the automobile speed at the automobile speed signal generator 2. On the other hand, the depression of the set switch 4 starts the count of constant frequency pulse with the oscillation count memory clircuit 3, the output from 2 and 3 is compared, the circuit 3 stores the value which is a given value close to zero for the difference, and if the automobile speed is out of this, the output current of the output Tr19 is increased or decreased to adjust the slottle angle and to keep the speed constant. Since the resistors 39 kand 40 cause sufficiently greater voltage division Vo, when the output and the speed are linear with each other, the self-hold of the relay 10 circuit is not released. But, if it is decreased than, e.g., the lower limit S1, the output of the amplifier 14 rapidly increases to cut off Tr9, resulting in performing required safe operation.
