摘要： There are provided a method of evaluating a basic curved surface for a reflecting mirror, an evaluation system for evaluating a basic curved surface for a reflecting mirror, and a computer-readable storage medium on which a program is recorded. There are provided a step (105a) of entering light source information on a light source and design information representative of a basic curved surface, and a step (105e) of displaying closed curved lines on a display device. The closed curved line data represents one or more closed curved lines which are included in one or more planes intersecting an axis Ax as well as in the basic curved surface. The axis Ax is determined to extend in a direction in which light from a light source is to be reflected by a reflecting mirror and to pass through a light source position defined by the light source information. The closed curved line data can be generated by obtaining lines of intersections of the plains and the basic curved surface. By displaying these cross sections, the schematic shape of the basic curved surface is visibly grasped with respect to the direction in which light from the light source is to be reflected.

摘要： In a vehicle headlight optical axis automatic adjusting system, a pitch angle in the longitudinal direction of a vehicle is calculated from a signal of a height sensor. Filtering corresponding to a control mode according to the acceleration is fixed and is not frequently switched unless the constant speed state of the vehicle continues for a predetermined time. The pitch angle may be calculated on the basis of the vehicle rear height value by using a prediction expression which is divided into a plurality of regions of vehicle postures according to loading conditions of an occupant load and a trunk load in correspondence with the vehicle type. The pitch angle may be updated when the vehicle enters a constant speed driving mode, i.e., stable driving mode, so that even when one trip is not finished the error is cancelled.
