Evolution of Vehicle Computer Systems By Its Technologies
ITS (intelligent transport systems) technologies accelerate the development of new vehicle functions using on-board electronic control systems coordinated with roadside facilities. Many kinds of advanced vehicle control systems and advanced information systems will be introduced into the market in the near future. The key technologies of these systems are not only the elemental technology of each mechanism, but also HMI (human machine interface) technology. Without proper HMI, drivers cannot use novel control systems safely, and cannot select suitable information during a drive. Furthermore, as an elemental technology for an on-board computer system, LAN systems with the proper gateway function are required in order to maintain and control various kinds of data, such as vehicle data, driver's condition and roadside information. Fusion of these data will produce new functions for the vehicle.
