IN-VEHICLE ELECTRONIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an in-vehicle electronic system for setting the number of cores to be driven and a driving frequency in the light of the total electric energy of an entire vehicle.SOLUTION: An engine ECU comprises a multi-core processor in which a plurality of variable-driving-frequency cores are mounted. The engine ECU sets a target value of the total electric energy of an entire vehicle on the basis of an acceleration state of the vehicle and a control objective determined in response to the acceleration state, and adjusts the number of cores to be driven and driving frequencies by a feedback control so that the total electric energy reaches this target value as soon as possible.SELECTED DRAWING: Figure 6
