  • Controls For Constant Speed Travelling (AREA)
  • Control Of Velocity Or Acceleration (AREA)

Abstract

PURPOSE: To stabilize a car speed satisfactory and prevent the hunting, by making a microcomputer store the car speed, outputting accelerating and decelerating signals at the time of acceleration and deceleration of a car, respectively, and controlling the car speed.
CONSTITUTION: The microcomputer 10 generates a control signal by receiving signals of the car speed sensor 1 and the engine cooling water temperature sensor 2. When this control signal has been received, the actuator 37 controls three built-in solenoid valves, and adjusts the opening of the throttle valve 36 of the carburetor 34. And in the event of the car speed is controlled state, the solenoid valve at the engine manifold side is operated by an acceleration control signal, and it is operated in the direction for opening the valve 36 by negative pressure. Also, the solenoid valve at the open air side is operated by a deceleration control signal, and it is operated in the direction for closing the valve 36. The remaining solenoid valve operates the release switch 4 when the car speed control is released, opens the passage of the open air side, and raises the deceleration effect by swiftly closing the valve 36. In this way, the stability of a car speed is made satisfactory and the hunting is prevented.
