PROBLEM TO BE SOLVED: To provide an automatic cruise controller that can hold excellent driving feeling regardless of the state of a travel road. SOLUTION: The target value AT is obtained on the basis of intervehicle time deviationΔT and relative speed Vr, and the target value AT is corrected using correction factors K0, K3 set according to the gradient and bending degree of a travel road. An output adjustment command VLc inputted to an engine output control part 20, and an auxiliary brake operation command BC inputted to a brake control part 18 are generated on the basis of the corrected target value ATh. In case of the target value AT being the positive value (that is, target acceleration) when travel resistance estimated from engine speed and fuel injection quantity is small (during travel on a downward slope, for instance), the correction factor K0 is set to the smaller value than 1.0 so as to decrease target acceleration. In case of the target value At being the negative value (that is, target deceleration), the correction factor is set to the larger value than 1.0 so as to increase target deceleration.
