Abstract

PURPOSE: To improve the driving performance of a vehicle, by enabling to accelerate the vehicle at a desired acceleration rate manually in case of accelerating the vehicle during its constant-speed operation and operating the same at a constant speed attained by acceleration by use of an automatic constant-speed operating system.
CONSTITUTION: A system for operating a vehicle at a constant speed, shown in the drawing, comprises a controller 20 for detecting the deviation between the actual vehicle speed and a setting vehicle speed and producing a control signal for reducing the deviation to zero, and a vacuum operated servo system for controlling the opening of a carburetor 3 in response to the output of said controller 20. The controller 20 is composed of an actual vehicle speed detecting section 30, a section 40 for storing a setting vehicle speed, and an error amplifying and controlling section for giving the above-mentioned control signal to a servo valve 7. In such a system, there is additionally provided an acceleration switch 60, which consists of a veraible resistor 62 and a switch 61 having an input terminal connected to a power circuit. Here, the output terminals of the switch 61 and the variable resistor 62 are connected respectively to a relay driving circuit and a power amplifier 52.
