Each EDB is composed of a material having a dynamic Young's Modulus of 0.1-2.5 MPa, and a resilience test rebound height less than 40, and is positioned between the grounding and frame to provide elastic restorative forces and damping in each of the respective directions. The use of EDBs simplifies construction, and allows for a more compact arrangement, without reducing VR efficiency.Type: GrantFiled: December 1, 2017Date of Patent: September 15, 2020Assignee: National Research Council of CanadaInventors: Amin Fereidooni, Viresh Wickramasinghe, Yong Eric Chen

Patent number: 10759407Abstract: An electric parking brake device generates pressing force by pressing friction materials against a brake disc by causing a piston to move by motor operation. A control device executes: parking processing wherein the motor increases the pressing force to an initial pressing force higher than a lower-limit pressing force; and re-drive processing wherein the motor is driven and the pressing force increased at a re-drive time, which is a predetermined time after the end of execution of parking processing. During parking processing, the control device uses one among the initial pressing force and the predetermined time, in addition to a pressing force decrease characteristic corresponding to an assumed temperature set for use in calculation, as a basis to calculate the other of the initial pressing force and the predetermined time such that the pressing force becomes equal to or less than the lower-limit pressing force at the re-drive time.Type: GrantFiled: July 27, 2016Date of Patent: September 1, 2020Assignee: ADVICS CO., LTD.Inventors: Masatoshi Hanzawa, Tetsuaki Tsuzuki
