VEHICLE TRAVELING CONTROL APPARATUS

A vehicle traveling control apparatus includes an imaging device, a sensor, an information storage, a traveling road detector, an imaging height detector, and a control unit. The traveling road detector detects that a vehicle is traveling on a road satisfying a condition. The imaging height detector detects a distance from a surface of the road to the imaging device position. The control unit includes a separation height estimator that estimates a height of a separation part, based on a result of the imaging height detector and the preset imaging device position, and a sensor height estimator that estimates a distance from an upper surface of the separation part to the sensor position, based on a result of the separation height estimator and the preset sensor position. The control unit stops detection by the sensor if a value estimated by the sensor height estimator becomes a threshold or less.
