摘要： PROBLEM TO BE SOLVED: To prevent the operation control of an actuator from unnecessarily stopping by switching the execution and the stop of the operation control of the actuator according to whether data of the specified object is stabley obtained or not. SOLUTION: When the object with a new label appears with the division of the object, the new object is decided as the new target in a target judgment unit 12. When the object before the division of the new target is the target, a locking off inhibition flag FL, is set to '1', the operation control of the actuators A1 and A2 is continued and the travel control of a self-vehicle, which follows the target, is executed. When the object appeared by giving the new label with the division of the object is decided as the new target, the locking off inhibition flag FL is set to '0' if the new target is not obtained by division. A locking on processing unit 13 temporarily stops the operation control of the actuators A1 and A2 .

摘要： PROBLEM TO BE SOLVED: To give time allowance for dealing with am avoiding operation and the like a driver by stopping the operation control of an actuator when an object selected as a specified object does not have the lateral width of not less than a prescribed value. SOLUTION: A part of a preceding vehicle is hidden in a state where a part of a four-wheel vehicle 18 which is difficult to be detected by an object detection sensor is interrupted between a self-vehicle 16 while it travels a straight road and a preceding vehicle 17 decided as a target, a state where the compact car of a two-wheel vehicle which is difficult to be detected by the object detection sensor is interrupted between the self-vehicle 16 and the preceding vehicle 17 decided as the target and a state where the four-wheel vehicle which is difficult to be detected by the object detection sensor is interrupted on the same turn track between the self-vehicle 16 during turn travel at a corner and the preceding vehicle 17 decided as the target, the preceding vehicle 17 being the target is judged that it does not have the lateral width of not less than the prescribed value W. It is judged that the object which is difficult to be detected by the object sensor exists. Then, the operation control of both actuators is stopped.

摘要： PROBLEM TO BE SOLVED: To prevent a decrease in operation response on a normal travel road surface while preventing the operation control of an actuator from being unsmooth owing to the detection of a reflecting object as to a vehicle which recognizes an object in front of itself and operating the actuator according to data on the recognized object. SOLUTION: Through a switching means 19 which performs switching operation according to the output of a road surface judging means 16 judging whether or not a reflecting object is installed on a road surface, the relative speed of the object recognized on the basis of the output of an object detection sensor detecting the position of the object in front of the vehicle to the vehicle is filtered by a 1st low-pass filter 17 when the road surface judging means 16 judges a nonreflection object installation road surface and then filtered by a 2nd low-pass filter 18 having a higher coefficient than the 1st low-pass filter 17 when the road surface judging means 16 judges the reflecting object installed road surface.

摘要： PROBLEM TO BE SOLVED: To surely determine an abnormality of detection in the case where detecting condition of the same object is intermittently continued with a non-detecting condition interposed between the detecting conditions by comparing the received quantity of light before detecting the non-detecting condition and the received quantity of light in the detecting condition after the non-detecting condition is passed with a threshold value. SOLUTION: A distance sensor for vehicle computes a distance from an object in front of a vehicle to the own vehicle. At the time of measuring distance, there is a case where a distance to a preceding vehicle cannot be accurately detected due to stains on the rear part of the preceding vehicle as an object and due to the lowering of the quantity of the reflected light from the preceding vehicle during the traveling. In the case where the same object detecting condition is intermittently continued with a non-detecting condition interposed between the detecting condition, and in the case where the received light variable just before losing the preceding vehicle and the light received variable at the time of new detection after passing the non-detecting condition are equal to a preset threshold value or less, abnormality of detection is determined. A determination that the preceding vehicle is hard to be detected is securely performed. When abnormality of detection is determined, an informing device is operated so as to inform the hard detecting condition to a vehicle driver.
