A vehicle control apparatus includes a branched lane determination section for determining whether an own vehicle lane in which an own vehicle is travelling is a branched lane, a reference line selection section for selecting as a reference line a lane marking on a side opposite to a side on which a branch lane branches from the own vehicle lane, a vehicle control unit for controlling the own vehicle to travel following an object preceding vehicle as a following control object, and a propriety determination section for excluding the object preceding vehicle from being the following control object if the own vehicle lane is determined to be a branched lane and a state quantity based on an offset distance between a movement track of the object preceding vehicle and the reference line exceeds a predetermined threshold.

The invention belongs to the technical field of measurement, and specifically discloses a method for measuring the vertical and horizontal offset of a positioning line. The method for measuring the vertical and horizontal offset of the positioning line comprises the following steps: step S1, determining the calculated mileage of a positioning point design coordinate and a line direction coordinateazimuth angle, and determining the offset distance and declination angle relationships between the positioning point and the mileage point when the positioning point deviates from the line design line; and obtaining line element solution element data; step S2, selecting an observation point; step S3, obtaining positioning point design data; step S4, collecting observation point coordinates; and step S5, obtaining the offset in the vertical and horizontal directions of the observation point; calibrating the point location and completing the plane positioning measurement when the offset meets the design requirements; and performing correction processing when the offset does not meet the design requirements. The method for measuring the vertical and horizontal offset of the positioning linecan effectively avoid the environmental impact around the positioning point and ensure the reliability of the observed data; the line king-pile coordinate calculation model is unified by using a mitigation curve to deduce an integral formula; and the vertical and horizontal offset of the observation point line is directly determined through comprehensively processing the design and observation coordinate data of the positioning point line.
