An adaptive cruise control (ACC) system is intended to reduce driver fatigue by automatically controlling the distance to the vehicle in front. A typical system now being offered by automobile manufacturers uses a radar to measure the distance to the vehicle in front and controls the engine, transmission and brakes so as to maintain a safe distance between vehicles. Currently, this system is assumed to be used primarily on limited-access highways. In the future, however, with improved functionality and performance and construction of the required infrastructure, this system is expected to be used in a wider range of circumstances, including city roads, to achieve an even safer driving environment. Hitachi, Ltd. positions the ACC system as one of the key systems of a driving safety support system and towards realizing a system that has high performance and advance functions, we have been developing driving environment sensing technology and driving control technology.
