<p>PURPOSE:To resume the control of the means of actuator of a constant-speed traveling device after the operation of a clutch is over, by regarding the operation of said clutch as the time of shifting a gear when the operating time of clutch is finished within a predetermined time. CONSTITUTION:When controlling for constant-speed traveling, a stored car speed is compared with the then car speed in an electronically controlling device 10, and control-solenoid controlled duty is determined so as to equalize the difference between them. For example, when deceleration is necessary, a duty ratio becomes low, the rate of time, at which a negative pressure control valve 110 allows the open air to pass through the inside of a negative actuator 100, is increased, and a throttle valve is closed by the negative pressure actuator 100. These operations are reversed at the time of accelerating. The electronically controlling device 10 regards the time of operating a clutch, if it is within a predetermined time, as the time for shifting a gear and, after the operation is over, resumes the control of the means of actuator, which has been released, to enable constant-speed traveling.</p> |
