PROBLEM TO BE SOLVED: To provide a tracking-travel control apparatus capable of suppressing deterioration in fuel economy caused by using a radar sensor, while maintaining an operation load burdened to a driver.SOLUTION: A tracking-travel control apparatus (1) includes: a millimeter-wave radar (2) for detecting an inter-vehicle distance relative to a preceding vehicle; a tracking-travel control part (20) for causing a vehicle itself to tracking-travel after the preceding vehicle; a near-infrared laser radar (4)/camera (6) for detecting a distance of the vehicle itself to a forward obstacle, the near-infrared laser radar/camera operating with smaller power consumption than the millimeter-wave radar; and an ECU (18) for stopping operation of the millimeter-wave radar in the case of the vehicular speed of the vehicle itself is equal to or less than a given speed, and resuming the operation of the millimeter-wave radar on the basis of the inter-vehicle distance relative to the preceding vehicle detected by the near-infrared laser radar/camera during the operation stop of the millimeter-wave radar. |
