Abstract:
1. A braking control apparatus for an electric vehicle, comprising: an electric motor configured to provide an electrical braking torque for road wheels connected thereto via a drive train on a basis of a calculated motor torque command value; a frictional braking device configured to provide a frictional braking torque for the road wheels on a basis of a calculated frictional braking torque command value; a target braking torque command value calculation section configured to calculate a target braking torque command value on a basis of at least one of a state of the road wheels and a braking request by a vehicle driver; a frequency component decomposition section configured to decompose the target braking torque command value into a first frequency component lower than a resonance frequency of the drive train and a second frequency component equal to or higher than the first frequency component; and a braking force control section configured to provide the electrical braking torque for the road wheels on a basis of the motor torque command value corresponding to the first frequency component and to provide the frictional braking torque for the road wheels on a basis of the frictional braking torque command value corresponding to the second frequency component.
