Abstract: A vehicle control apparatus includes a first section that recognizes a lane boundary line of a lane in which a vehicle is traveling. A second section recognizes a present position of a predetermined reference point of the vehicle. A third section calculates a predicted position of the reference point, wherein the predicted position is a predetermined interval ahead of the present position. A fourth calculates an imaginary lane boundary line, wherein the imaginary lane boundary line is tangent to the lane boundary line at a point close to the predicted position. A fifth section performs a control of preventing the vehicle from deviating from the lane by controlling the vehicle depending on positional relationship between the vehicle and the lane boundary line. A sixth section selectively permits and suppresses the control depending on positional relationship among the imaginary lane boundary line, the present position, and the predicted position.

Abstract: In a brake control apparatus with wheel-brake cylinders mounted on respective road wheels, a pump is provided to supply a fluid pressure to each of the wheel-brake cylinders by normal rotation of the pump. A control unit is provided to control rotational motion of the pump to bring an actual wheel-cylinder pressure of each of the wheel-brake cylinders closer to a target wheel-cylinder pressure. Also provided is a pump reverse-rotation suppression device that suppresses reverse rotation of the pump, only when the reverse rotation of the pump is detected.

Abstract: A brake control apparatus for a wheeled vehicle includes wheel cylinders; a pump hydraulically connected to the wheel cylinders for pressurizing the wheel cylinders; a motor for driving the pump; control valves hydraulically connected between the pump and respective ones of the wheel cylinders for allowing fluid communication therebetween with respective variable cross-sectional flow areas; a pressure sensor for measuring an internal pressure of each of the wheel cylinders; and a control unit. The control unit performs wheel cylinder pressure control of controlling the internal pressures of the wheel cylinders by the motor and the control valves so as to conform the measured internal pressures of the wheel cylinders to respective ones of desired internal pressures of the wheel cylinders. During the wheel cylinder pressure control, the control unit constantly keeps a condition that the cross-sectional flow area of at least one of the control valves is maximized.

Abstract: A brake control apparatus for a vehicle includes a wheel cylinder, a pump for pressurizing a brake fluid in the wheel cylinder, and an electric motor for driving the pump. A controller operates the electric motor so as to conform an internal pressure of the wheel cylinder to a desired internal pressure of the wheel cylinder, and produces a torque applied to the electric motor in a first rotational direction, while the pump is stopping from a state in which the electric motor is rotating in a second rotational direction opposite to the first rotational direction so as to allow the pump to pressurize the brake fluid in the wheel cylinder.
