Patent number: 10365175Abstract: A surface pressure measuring device includes an abutting plate, a lift, a probe, a piezo actuator and a controller. A pinhole is formed in the abutting plate at an abutting surface that abuts a target. The lift causes the target to abut the abutting surface such that the target is compressed to a predetermined thickness. The probe is inserted through the pinhole to be movable in an axial direction of the pinhole. The piezo actuator holds a state in which a tip surface is flush with the abutting surface as the probe resists a repulsive force received from the target while the lift causes the target to abut the abutting surface. The controller calculates a local surface pressure of the target from a load applied to the probe and an area of the tip surface of the probe.Type: GrantFiled: July 31, 2017Date of Patent: July 30, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsutomu Hosoi, Ryotaro Okamoto, Takahiro Fukuda, Shinichi Miura
