To provide an internal combustion engine system with an electric motor which is improved so as to be capable of satisfying even a traveling requirement of a vehicle while suppressing the overheat of an engine exhaust pipe.SOLUTION: An internal combustion engine system with an electric motor comprises: power generation means arranged at a vehicle mounted with an internal combustion engine, and generating electrical power by power of the internal combustion engine; charge means for charging a battery for supplying power to the electric motor which drives the vehicle by the power generation means; means for prohibiting a post-stop restart of the internal combustion engine after a stop of vehicle when a temperature of an exhaust pipe of the internal combustion engine exceeds a preset determination temperature; and correction means for performing either of corrections of a first correction for increasing a charge amount of the battery by the charge means when the temperature of the exhaust pipe exceeds the determination temperature, and a second correction for reducing an SOC determination value for performing a charge operation for charging the battery by starting the stopped internal combustion engine when an SOC of the battery is the SOC determination value or lower.SELECTED DRAWING: Figure 2
【課題】エンジン排気管の過熱を抑制しつつ車両の走行要求も満たすことができるように改良された電動機付き内燃機関システムを提供する。【解決手段】電動機付き内燃機関システムは、内燃機関を搭載した車両に設けられ、内燃機関の動力で発電する発電手段と、車両を駆動させる電動機に電力を供給するためのバッテリを発電手段で充電する充電手段と、内燃機関の排気管の温度が予め定めた判定温度を上回る場合に、車両の停止後における内燃機関の停止後再始動を禁止する手段と、排気管の温度が判定温度を上回る場合に、充電手段によるバッテリの充電量を増加させる第一補正と、バッテリのSOCがSOC判定値以下であるときには停止された内燃機関を始動することでバッテリを充電する充電動作を実施するためのSOC判定値を低減する第二補正と、のうちいずれかの補正を実施する補正手段と、を備える。【選択図】図2
