Apparatus for and method of controlling vehicular systems while travelling

摘要

A vehicle-mounted travel control system including a navigation system control section which controls a storage section, a position detection section for detecting the present position of the vehicle, a course decision section for deciding an intended travel course of the vehicle. The travel control system also includes a central control section for managing control sections based on information of various sensors installed in the vehicle. The system also includes a terminal device which is connected to the navigation system control section and the central control section. The terminal device is adapted to determine at least one predetermined time responsive to an actual vehicle speed based on actual vehicle speed information transferred from said central control section, and the navigation system control section is adapted to determine an intended travel position after elapse of a predetermined time with reference to the present position of the vehicle based on the vehicle speed and predetermined time transferred from the terminal device.
