dc.description.abstract | Provided are a wedge angle adjusting device and method. A device for adjusting a wedge angle of a variable wedge of an electro wedge brake (EWB) includes a movable wedge including an inclined surface and a counter wedge which includes an inclined surface disposed to face the inclined surface of the movable wedge and is disposed to face the movable wedge. The wedge angle adjusting device includes a frictional coefficient estimate unit configured to estimate a frictional coefficient between a pad and a disc of the EWB, a wedge angle command unit configured to calculate a wedge angle command value, based on a estimation of frictional coefficient estimated by the frictional coefficient estimate unit, and a wedge control unit configured to adjust the wedge angle according to the calculated wedge angle command value. | - |

dc.description.claim | 1. A device for adjusting a wedge angle of a variable wedge of an electro wedge brake (EWB) which includes a movable wedge, including an inclined surface, and a counter wedge, which includes an inclined surface disposed to face the inclined surface of the movable wedge and is disposed to face the movable wedge, the device comprising: a frictional coefficient estimate unit configured to estimate a frictional coefficient between a pad and a disc of the EWB;a wedge angle command unit configured to calculate a wedge angle command value, based on the frictional coefficient estimated by the frictional coefficient estimate unit; anda wedge control unit configured to adjust the wedge angle according to the calculated wedge angle command value,wherein the wedge angle command unit calculates the wedge angle command value “αcommand” by using Equation below: [Image]where {tilde over (μ)}i means the frictional coefficient estimated by the frictional coefficient estimate unit, Fai means an actuating force which is applied to the movable wedge at an i-th sampling time, Fni means a clamping force which is applied to the pad at the i-th sampling time, wherein i is an integer equal to or greater than one. | - |
