Abstract
A distance measuring system for an automotive vehicle is provided. The distance measuring system outputs laser pulse signals at given angular intervals over an object detectable zone, and receives a signal produced by reflection of one of the outputted signals from a reflective object to determine the distance to the object. The distance measuring system also includes an object type determining function of determining a type of the object present in the object detectable zone. When there are a plurality of signals produced by dispersion of a single shot of the laser pulse signals, and when distances derived by signals reflected from most of the object detectable zone show given shorter distance values, the object present in the object detectable zone is identified as a particle such as snow or fog floating in the air.
