An air gap, which in idle mode is smaller or larger than a desired air gap, is provided between the input element and the force transmission unit. A method for operating the brake booster includes generating a support force prior to a braking intent to be anticipated or immediately after detection of a braking intent, in a time span before or immediately after detection of an actuation of the input element.

摘要： This hydraulic braking device is provided with: a tubular cylinder; an assisting piston, which is housed in the cylinder so as to be able to move reciprocally, faces a reservoir formed inside the cylinder, and assists a master piston, in a master cylinder, that generates hydraulic pressure for generating a braking force by reciprocally moving from one side to the other as a result of a fluid flowing into the reservoir from a supply source; and a seal member, which is elastically deformable and which seals the reservoir. When the assisting piston is at a location on one side, the reservoir is compartmentalized into a first chamber that communicates with the supply source, and a second chamber that communicates with the first chamber through a restricting flow passage, and the seal member seals the second chamber.

摘要： A hydraulic-pressure control device includes a regulator including a housing, a control piston in the housing, an input chamber at a rear of the piston, and an output chamber in front of the piston; and an input-hydraulic-pressure control device which controls hydraulic pressure in the input chamber to move the piston forward or backward to raise or reduce hydraulic pressure in the output chamber. The input-hydraulic-pressure control device includes a moving-direction control unit which, when a difference obtained by subtracting an actual hydraulic pressure in the output chamber from a target hydraulic pressure in the output chamber is less than a pressurization-side set value, controls the hydraulic pressure in the input chamber to move the piston backward; and when the difference is greater than a reduction-side set value, controls the hydraulic pressure in the input chamber to move the piston forward.

摘要： A braking device for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve installed in a flow path connecting between a brake fluid accumulator and a servo chamber of the hydraulic booster, and a collision avoidance controller. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the first solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, the emergency braking is achieved only using the solenoid valve, thus allowing an emergency avoidance mechanism of the braking device to be constructed with a minimum of equipment and facilitating the mountability of the braking device in vehicles.
