Method for determining distance between object e.g. person and motor vehicle e.g. car, involves receiving light reflected by object using light receiver at predetermined angle of incidence

摘要

The method involves irradiating a light at a predetermined viewing angle from a light transmitter (A) to object (O). The light reflected by object is received by a light receiver (6) at a predetermined angle of incidence. The distance (h) between vehicle and the object is detected in response to the viewing angle, angle of incidence, a distance (S') between object and light transmitter, and distance (S'') between light receiver and object. Independent claims are included for the following: (1) sensor system for determining distance between object and vehicle; and (2) vehicle.
