ABSTRACT:
A vehicle travel control system includes a cruise control ECU, an engine control ECU and a brake control ECU. The cruise control ECU checks whether a driver's actual concentration degree is insufficient relative to a required concentration degree in terms of safety in surrounding environments of the subject vehicle. When such possibility arises, even during the cruise control, the speed of the subject vehicle is controlled to match a control vehicle speed lower than a set vehicle speed or a control distance to a preceding vehicle.
