Abstract

PURPOSE: To control rotating velocity to a setpoint as well as to make controls of a throttle valve actuator in such a way that actual value and setpoint operations go along with engine rotating velocity, and at the time of treadling an accelerator, lower limits of the differnce are settled between the both signals which are released.
CONSTITUTION: Intermittent signals from a breaker point 12 of an engine igniter as actual value of rotating velocity input through an ignition switch 11 and a transistor 21, etc. to an operational amplifier 28. Further, signals from a cooling system thermistor 29 and an air conditioner switch 36 as a second signal of target rotation input through a transistor 33, etc. toward the front of an amplifier 47. And third signal calculated by the amplifier 47 is taken within lower limits which are settled by an amplifier 50. Its fourth signal is calculated with the signal from 29 by the transistor 55, which actuates an actuator 59. Besides, when an accelerator 72 is treadled, the signal takes action of releasing the settld lower limits of the amplifier 50.
