Title:
BRAKE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/048291
Kind Code:
A1
Abstract:
A torque command calculation unit (40) of a braking force control unit (400) calculates a torque command value (Trq*) for a motor (60) on the basis of required braking force commanded from the outside. The relationship between the torque of the motor (60) and braking force generated in electric brakes (81-84) has hysteresis characteristics. When the torque increases, the braking force increases along a positive efficiency line, and when the torque decreases, the braking force decreases along an inverse efficiency line. A specific controller (48) of the torque command calculation unit calculates the torque command value (Trq*) so that the actual load is caused to approach a load command value or the actual position is caused to approach a position command value. A control adjuster (471, 472, 473) adjusts parameters of the specific controller (48), or of control calculation at the input side or output side of the specific controller (48), during an increasing operation, a decreasing operation, or a transition between the increasing operation and the decreasing operation.
