Abstract: A vehicle control unit includes interface software memory means storing an interface software program for connecting an application software program with an OS (operating system) in an internal ROM, a CPU (central processing unit) for performing computation for the application software program and the interface software program, a RAM (erasable memory) storing data such as the result of computation, an I/O unit for extending the control unit, and extending means for communicating memory data through a bus or a LAN. A single-chip micro-computer used in vehicle control permits an increase in input/output points or the addition of functionality, in which case an application software program can continue to be used simply by rewriting the interface software program, without further remanufacturing of the core unit.

Abstract: A navigation system for guiding a moving object from a current position to a destination includes a setting device that sets the current position and the destination, a sensor that detects movement of the moving object, a computing device that calculates move distance that the moving object has moved from the current position based on data outputted from the detecting sensor, and that determines a position of the moving object by shifting the calculated move distance from the current position on path data between the current position and the destination, which has been obtained by a path planning. The navigation system further includes a display device for displaying path guidance information depending on the determined position of the moving object.

Abstract: An object of the present invention is to provide a control unit for vehicle where increase in number of input/output and upgrading of function can easily be performed and, in addition to this, changing of a program in a control unit can easily be performed even when a single-chip micro-computer is used.

Abstract: A vehicle which includes a plurality of peripheral systems has a plurality of control units which transmit data to each other via a local area network, and which control the peripheral systems in response to sensor signals received from vehicle operating parameter sensors. A first control unit has a memory which stores a first interface software program which receives input signals from sensors and processes such signals for controlling at least one peripheral system of the vehicle, by means of an application software program and first and second interface software programs. A second control unit has a memory which stores an application software program for processing input signals for controlling at least one other peripheral system of the vehicle via a third interface software program. The second control unit receives input data from the first control unit via the local area network.
