PURPOSE:To attain independent or parallel related control, by providing plural sets of microprocessors that perform the control or display of an engine, etc. which is mounted on a car and having a virtually signal unit of main microprocessor to control the above-mentioned microprocessors. CONSTITUTION:Plural follower electronic controllers S1-Sn are connected to a bus B, and a main microprocessor CPU(M) and a main storage circuit MEM(M) are connected to the bus B. For instance, the controller S1 controls the timing of an engine, and the detected D electric signal is fetched to a microprocessor CPU(S) via an input/output interface I/O to receive an arithmetic process with connection of the circuit MEM(S). Thus an actuator A is controlled. The controllers S2, S3 and Sn control the starting system, the control system and the alarm display system of the engine, respectively. These controllers receive an integrated control from the CPU(M) to perform independent and parallel control as well as cooperative control with reception of the related information. |
