摘要：
A constant speed cruise control system of duty ratio control type for approximating an actual tarveling car speed to a stored target car speed, by on/off control of a control valve (10,89a) of an actuator (ACT,102,89,155) to adjust the throttle valve opening degree by an output duty ratio D obtained from a control line (70) having a gradient showing a conversion characteristic of car speed and duty ratio. The system has a controller (ECU) in which
a set duty ratio SD corresponding to the target car speed is calculated as and the output duty ratio D is calculated as where G: gradient of control line
ΔV: car speed deviation
DM: integrating element responding quickly to duty ratio change
SD1: integrating element responding slowly to duty ratio change
n: constant and the controller (ECU) corrects to integrate the set duty ratio SD in a direction of approximating the output duty ratio D.
