Abstract:
In a braking control apparatus for an electric vehicle, a target braking torque command value calculation section calculates a target braking torque command value on a basis of at least one of a state of road wheels and a braking request by a vehicle driver, a frequency component decomposition section decomposes a target braking torque command value into a first frequency component lower than a resonance frequency of a drive train and a second frequency component equal to or higher than the first frequency component, and a braking force control section provides an electrical braking torque for road wheels on a basis of a motor torque command value corresponding to the first frequency component and provides a frictional braking torque for the road wheels on a basis of a frictional braking torque command value corresponding to the second frequency component.
