Abstract
A vehicle control unit comprises an interface software memory for storing an interface software program for connecting an application software program with an operating system in an internal ROM, a central processing unit for performing computation of the application software program and the interface result of computation, an I/O unit for extending the control unit, and extending means for communicating memory data through a bus of a LAN. A single-chip micro-computer is used in vehicle control.
Claims11
An automobile control unit for controlling an automobile having a sensor for detecting an operational condition of said automobile and a control actuator for controlling said automobile on the basis of a signal from said sensor, comprising:
