Beschreibung
Zusammenfassung:	A brake ECU (abnormality detection device) includes: an operating amount obtaining portion configured to obtain a measurement value of a stroke; a hydraulic pressure obtaining portion configured to obtain a measurement value of a reaction force hydraulic pressure having a mutual relationship with respect to the stroke; an operation direction determining portion configured to determine directions of operation of outputs from a stroke sensor and a pressure sensor; a failure detection range switching portion configured to switch the failure detection range for detecting failures of a hydraulic pressure braking force generating device in accordance with the direction of operation; and a failure determining portion configured to determine the failure of the hydraulic pressure braking force generating device from the failure detection range switched by the failure detection range switching portion, the measurement value of the stroke, and the measurement value of the reaction force hydraulic pressure.
