Abstract
A braking apparatus for a vehicle includes a permanent magnet synchronous motor including a rotor having a permanent magnet, and a stator capable of driving the rotor to rotate and configured to couple the rotor to each of at least a pair of wheels of the vehicle; a power accumulating portion that accumulates power to be supplied to the permanent magnet synchronous motor; a conversion control portion that converts the power of the power accumulating portion to excite the stator and control the rotation of the rotor; and an in-phase excitation control portion that applies exciting brake to the wheel by exciting the stator by supplying power in the same phase as the excitation with respect to the stator in the direction of rotation of the rotor according to the control performed by the conversion control portion, wherein the wheel is stopped by the exciting brake.
