    Abstract: A vehicle brake controller is capable of executing limit control when a driver is performing a brake pedal operation during turning of a vehicle, to limit an increase in a braking force applied to an inner wheel that is a wheel positioned on the inner side of the turn. The vehicle brake controller is configured to start the limit control when a wheel state value that becomes greater as deceleration of the inner wheel becomes greater exceeds a start determination value that is set to a value greater than zero.

    Abstract: A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.

    Abstract: A brake device for a vehicle is equipped with an electric motor which drives a pump to deliver brake fluid to a wheel cylinder installed in a wheel of the vehicle. The brake device works to control pressure of the brake fluid in the wheel cylinder for creating a target braking force. In response to an increase in stroke of a brake pedal, the brake device elevates the pressure in the wheel cylinder gradually without sharply changing it. This eliminates deterioration of a driver's braking feeling arising from a variation in deceleration of the vehicle and ensures smooth deceleration of the vehicle intended by the driver of the vehicle.

    Abstract: A rotating pump includes an outer and an inner rotor disposed in a casing with a gap between the casing and the outer rotor. The rotating pump also includes a first and a second sealing member in the casing to define a low-pressure region and a high-pressure region within the gap. Each of the first and second sealing members is made up of a seal functioning portion and an elastically pressing portion. The seal functioning portion includes a resinous member and a deformation-suppressing member. The resinous member contacts the outer rotor and a low-pressure side inner surface of the casing to establish a difference in pressure between the low-pressure region and the high-pressure region. The deformation-suppressing member works to stop the resinous member from deforming undesirably. This minimizes the risk of breakage of the resinous member and enables the rotating pump to discharge the fluid at an increased pressure.

    Abstract: A gear pump apparatus is equipped with a pump and a sealing mechanism which is made up of an outer member, an inner member, and a rubber member fit between the outer and inner members. The inner member has a pressure-exerted surface to which pressure, as produced by contact of the rubber member with the inner member arising from application of discharge pressure of the pump, is applied. The pressure-exerted surface has a flange which creates thrust to move the inner member away from the gear pump, thereby bringing the inner member against an inner wall of a pump casing to develop a hermetical seal between a high-pressure region and a low-pressure region within the pump casing. This eliminates the leakage of pressure and ensures torque required for a pumping operation of the pump.
