Simplification of System Inputs and Outputs for MPU Control Units

Some methods are suggested for organizing simple automotive sensor and actuator elements to minimize wires and use the analytical capability of the program of instructions stored within the memory of the electronic controller to extract information or manipulate the actuators. An information exchange system between microcomputer control units is described which allows trading of information. In this way, no sensors need be duplicated and each microcomputer serves as a single concentrator which permits sending a large group of facts from one part of the vehicle to another using only a few wires.
