Document Type and Number:
WIPO Patent Application WO/2019/039397
Kind Code:
A1
Abstract:
Provided is an electric brake device which achieves both NVH, a collective term referring to noise, vibration, and harshness, and control accuracy. A control device (2) of the electric brake device 1 is provided with: a wheel motion estimation means (22); a control calculation function unit (20) which switches an operation amount between a plurality of mutually different operation amounts, in accordance with a state amount of an electric motor (4), and an switching intensity determination function unit (21) which, on the basis of a brake force command value and the like, determines the sharpness of switching required for switching the operation amount in the control calculation function unit (20). The switching intensity determination function unit (21) includes the function for determining whether, during switching of the operation amount, to perform smooth switching with respect to a determined switching parameter, and/or the function for modifying the gradient indicating the sharpness of smooth switching with respect to the determined switching parameter.
