Toward the realization of more secure and safer intelligent cars, we are engaged in the development of advanced road transportation system ITS (Intelligent Transport Systems). Among the nine fields that comprise ITS, we are working on three fields - "advances in navigation systems," "assistance for safe driving," and "increasing efficiency of commercial vehicle operation." Using advanced communication and information processing technology, we have developed systems for assisting safe driving for the next generation. Thus, we offer new added value - "intelligent cars." Millimeter-wave rader, which uses rader technology and a millimeter-wave device as advanced technology, is one of the important factors for safe driving assistance systems. This rader can precisely measure ranges, relative speeds and directions of the vehicles ahead. It realizes safe, secure and comfortable easy driving by applying vehicle control such as maintaining appropriate distance between the cars and operating brake for alleviating collision damage. The possibility of a next-generation cruising system will be promoted further. As a step toward the dream of automatic driving, we are conducting research and development into this safety technology. In the system, a car-equipped camera recognizes details of surrounding information on the road that the driver sees visually, and accurately determines the driving environment that changes constantly. This system automatically sends taxi location information from GPS to a central control station through digital radio. When a central control station receives a dispatch request call from a customer, the system automatically searches for the nearest taxi from the customer with CTI (Computer Telephony Integration) function and transmits the dispatching data to the selected taxi. Since this automatic dispatching system will allow smooth and speedy service managemet, efficiency of the operation and customer service can be effectively improved, and the burden of drivers can be greatly reduced.
