    • A roadside detection system installed in a vehicle to detect a roadside of a road on which the vehicle travels includes detection results acquiring means, first edge line detecting means and second edge line detecting means. The detection results acquiring means emits light waves or electromagnetic waves to a target detection region in which an object to be measured is detected and acquires an objective distance and a reflection intensity, for each of separate regions obtained by separating the target detection region into a plurality of divisions. The first edge line detecting means detects a first edge line that is a candidate of a roadside based on each objective distance. The second edge line detecting means detects a second edge line that is a candidate of a roadside based on each reflection intensity. A driver assistance system and a roadside detecting method are also provided.

    • An apparatus and method for recognizing presence of an object is provided, the apparatus and method are mounted on or implemented a vehicle. In the apparatus and method, by scanning a beam-shaped electromagnetic wave, data showing reflection intensities of reflected waves and distances between the vehicle and objects outside the vehicle are obtained. Based on the detected data, characteristics presented by frequency distributions of the distances and intensity frequency distributions of the refection intensities obtained in multiple rows in a field of view in the height direction of the vehicle. The characteristics depend on an angle of the electromagnetic wave to a road on which the vehicle travels. It is determined that the characteristics are obtained from the road when the characteristics meet predetermined requirements.

    • A visibility condition determining device for a vehicle has a lighting device, an in-vehicle camera and an image processing unit. The lighting device is mounted on the vehicle and irradiates an outside of the vehicle with its light beam. The in-vehicle camera picks up an image including a transmission space through which the beam irradiated from the lighting device is transmitted in an imaging area, and including a non-irradiated area that is not directly irradiated with the beam in a background of the transmission space in the image. The image processing unit determines a visibility condition outside of the vehicle based on a brightness of the non-irradiated area in the image which is picked up by the in-vehicle camera when the lighting device irradiates outside of the vehicle.
