The present invention estimates the temperature of a catalyst (EHC) with high accuracy. An electronic control device according to the present invention is used for controlling an engine system including: an internal combustion engine; an electric motor capable of dragging the internal combustion engine; a catalyst that purifies exhaust gas, is provided in an exhaust passage of the internal combustion engine, and has a function of heating by power supply; and a downstream temperature sensor disposed downstream of the catalyst. An electronic control device includes: a control unit that drags an internal combustion engine by an electric motor; and an estimation unit capable of implementing a first estimation process in which the temperature of the catalyst is estimated on the basis of detection information from the downstream temperature sensor when the internal combustion engine is dragged.

    本发明高精度地估算催化剂(EHC)的温度。本发明的电子控制装置用于对发动机系统进行控制,该发动机系统包括:内燃机;能够对内燃机进行拖动的电动机;对废气进行净化的催化剂,其设置在内燃机的排气通路中,具有通过供电而加热的功能;和设置于催化剂的下游的下游温度传感器。电子控制装置包括:控制部,其利用电动机对内燃机进行拖动;和估算部,其能够实施第一估算处理,在第一估算处理中,基于对内燃机进行拖动时的下游温度传感器的检测信息来估算催化剂的温度。
