Abstract

The present application discloses a brake device for a vehicle, including: a permanent magnet synchronous motor, which includes a rotor with permanent magnets and a stator capable of driving the rotor to rotate, and is configured to couple the rotor to at least one of the vehicles. for each of the wheels; an electric power storage section that accumulates electric power to be supplied to the permanent magnet synchronous motor; a conversion control section that converts the electric power of the electric power storage section to excite the stator and control the rotor rotation; and an in-phase excitation control section that applies excitation braking to the wheels by exciting the stator by supplying electric power in a phase that is different from that in the rotation direction of the rotor according to control performed by the conversion control section. On the same phase with respect to the excitation of the stator, wherein the wheels are stopped by excitation braking.

Description

technical field [0001] The present disclosure relates to a brake device of a vehicle, and more particularly, to a brake device of a vehicle configured to stop rotation of a wheel by an electric motor. Background technique [0002] Examples of the braking device of the vehicle generally include a hydraulic braking apparatus employing hydraulic braking. However, in electric vehicles or so-called hybrid vehicles in recent years, regenerative braking using an electric motor is used. For example, JP-2007-106385A (reference 1) discloses a braking force control device configured to generate an allowance margin of motor torque for both the regenerative side and the electric running side to Expand the control width of the motor torque. In JP-11-4504A (Reference 2), cooperative control of regenerative braking and hydraulic braking is performed. In contrast, in JP-2003-287069A (Reference 3), there is disclosed an electric motor braking device configured to convert the rotational mot...
