Abstract
A constant travel speed control apparatus is for use in a vehicle and utilizes time delay control which is a kind of adaptive control for estimating an unknown term. A plurality of targeted paths, each having a certain waveform, for causing the actual speed of the vehicle to converge on a target speed are provided and an error vector is defined on the basis of the paths. The actual speed of the vehicle can be made to converge on the target speed thereof with a constant convergence performance along a target path in spite of the fluctuation of vehicle dynamic characteristics.
