    摘要: An SR motor includes a stator having a plurality of salient poles and a rotor having another plurality of salient poles. Windings are wound around the plurality of salient poles and magnetic fields are generated in the plurality of salient poles. The number of salient poles of the rotor is determined depending upon a number of the salient poles of the stator. A supply mode for supplying power from a power supply to the windings, a reflux mode for setting both terminals of the windings to an identical potential, and a regenerative mode for recovering an electromotive force generated in the windings into the power supply are executed as the rotor rotates. The reflux mode and the regenerative mode are preferably repeated in a period during which the inductance of the windings is reduced as the rotor rotates.

    摘要: A brake pressure is controlled with the left and right front wheels of a vehicle as one group, and the left and right rear wheels as another group. Alternatively, the right front wheel and left rear wheel form one group, and the left front wheel and right rear wheel form another group. Brake pressure is supplied individually to these groups by a first actuator group comprising one or more actuators and a second actuator group comprising one or more actuators. When a fault occurs in an actuator in the first actuator group, the first actuator group is controlled so as not to generate brake pressure, and when a fault occurs in an actuator in the second actuator group, the second actuator group is controlled so as not to generate brake pressure. In this way, unbalance of braking force on the left and right wheels due to a fault in an actuator is prevented, and turning of the vehicle due to this unbalance is suppressed.

    摘要: An electromechanical brake system for a vehicle has a brake actuator installed to each wheel of the vehicle and a controller for controlling an operation of each brake actuator. The brake actuator is constituted to clamp a disc rotor by a pair of brake pads through a rotational motion converting mechanism according to an operation of the motor. The rotational motion converting mechanism is constituted by a screw shaft integrally connected to a rotation shaft of the motor and a ball screw screwed with the screw shaft and integrally connected to one of the pair of brake pads. When the vehicle is put in a stopping state, the controller drives the motor so that an ordinary use region of the screw shaft, which is contacted with balls of the ball nut during a brake operation, is faced with a lubricant hole formed at an end portion of the ball nut.

    摘要: A first and a second power roller supported by trunnions are gripped between an input disc and an output disc disposed on an identical rotation axis. The gyration angles of the power rollers are varied by driving the trunnions in a direction perpendicular to the rotation axis by an oil pressure actuator. The oil pressure of the actuator is controlled based on a target gyration angle, and the gyration angle of the first power roller is fed back to the oil pressure control. Vibration of the first power roller due to external disturbance is prevented from affecting the second power roller via oil pressure control by making a force according to a displacement of the first power roller in the direction perpendicular to the rotation axis, act only on the trunnion supporting the first power roller.
