Abstract
A constant-speed running apparatus for a vehicle comprising a throttle-valve actuator for activating a throttle-valve opening angle of a vehicle engine, a constant-speed running controller for controlling the throttle-speed running, a continuously variable transmission (CVT) which is constructed in a power transmission path of the vehicle engine, and a CVT controller for controlling a transmission-ratio of the CVT; further comprising a detecting element constructed in the constant-speed running controller for a control efficiency of the constant-speed running for detecting an acceleration demand of a driver and for informing the CVT controller of the demand; and further comprising a correction element for calculating a corrected transmission-ratio as a corrected vehicle acceleration corresponding to a target vehicle accelerating force on the basis of the acceleration demand detected by the detecting element.
