Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a brake system capable of obtaining sufficient brake force even when abnormality occurs in a drive of an electric air compressor.SOLUTION: A brake system 1 of a hybrid vehicle includes: an air tank 50 which stores compressed air to be supplied to an air brake mechanism; an electric air compressor 40 and an engine-drive air compressor 45 which generate the compressed air and supply the compressed air to the air tank 50; a switching part 60 which switches a propriety of supply of the compressed air by means of the engine-drive air compressor 45 for the air tank 50; and a control part 70 which judges whether a drive of the electric air compressor 40 is normal or not and when judging that abnormality occurs in the drive of the electric air compressor 40, supplies the compressed air from the engine-drive air compressor 45 to the air tank 50 by controlling the switching part 60.SELECTED DRAWING: Figure 1 【課題】電動エアコンプレッサの駆動に異常が発生した場合であっても十分な制動力が得られるブレーキシステムを提供する。【解決手段】ハイブリッド車両のブレーキシステム１は、エアブレーキ機構に供給される圧縮エアを貯留するエアタンク５０と、圧縮エアを生成してエアタンク５０へ供給する電動エアコンプレッサ４０及びエンジン駆動エアコンプレッサ４５と、エアタンク５０に対するエンジン駆動エアコンプレッサ４５による圧縮エアの供給の可否を切り替える切替部６０と、電動エアコンプレッサ４０の駆動が正常であるか否かを判定し、電動エアコンプレッサ４０の駆動に異常が発生していると判定した場合、切替部６０を制御して、エンジン駆動エアコンプレッサ４５からエアタンク５０へ圧縮エアを供給させる制御部７０と、を備える。【選択図】図１
