This paper describes a vision system, which is based on ASIC (Application Specific Integrated Circuit) approaches, for vehicle guidance on highways. After reviewing related work in the field of intelligent vehicles, stereo vision, and ASIC-based approaches, the paper focuses on a stereo vision system developed for intelligent cruise control. The system measures the distance to the vehicle in front using trinocular triangulation. Application specific processor architectures were developed for low mass-production cost, real-time operation, low power consumption, and small physical size. The system was installed in a trunk of a car and evaluated successfully on highways.
