    摘要： An increase in startup current supplied to a motor is suppressed at an initial stage of starting automatic braking control, while current supply to the motor is performed in a fully energized state after the automatic braking control is started. While output of the motor is increased by controlling the motor in the fully energized state so that a high braking force with high responsiveness is obtained, startup current is prevented from becoming excessive by performing high frequency control only at startup. Thus, decrease in battery voltage is minimized and thus the occurrence of malfunction is minimized in the control systems of various electrical components used in the vehicle.

    摘要： A braking device for a vehicle is provided which is equipped with a hydraulic booster. The hydraulic booster includes a master cylinder, a braking simulator, and an input piston. The input piston is disposed in the master cylinder in connection with a brake actuating member such as a brake pedal and is moved in response to a braking effort applied to the brake actuating member to drive a spool valve which switches among a pressure-reducing mode, a pressure-increasing mode, and a pressure-holding mode. The braking simulator works to urge the input piston rearward and is disposed inside a cylindrical cavity of the master cylinder of the hydraulic booster. This layout improves the mountability of the braking device in vehicles.

    摘要： A braking apparatus for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve, and a collision avoidance controller. The solenoid valve selectively exerts the hydraulic pressure of brake fluid stored in an accumulator on a spool valve in the booster. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, emergency braking is achieved by installing the solenoid valve to selectively exert the hydraulic pressure on the spool valve, thus allowing an emergency avoidance braking system to be constructed with a minimum of equipment and facilitating the mountability of the braking apparatus in the vehicles.

    摘要： An electric braking device includes: a first valve unit for adjusting a first differential pressure between a master cylinder side liquid pressure and a wheel cylinder side liquid pressure; a storage unit forming a fluid storage chamber; second valve units for adjusting a second differential pressure between the master cylinder side liquid pressure and a storage chamber side liquid pressure; an electric pump for discharging the fluid in the storage chamber; and a control unit which, while operating the electric pump during a time from initiation of braking force application until a request value acquired by a request braking force acquiring unit reaches a maximum value, controls the first valve unit such that the first differential pressure becomes zero, and controls the second valve units such that the second differential pressure becomes zero.

    摘要： A braking device for a vehicle is provided which is equipped with a hydraulic booster in which a hydraulic pressure chamber is formed. The hydraulic booster has a plurality of fluid flow paths which are shaped to create convective spiral flows of brake fluid to flush bubbles of air into the spiral flows of brake fluid every braking operation. The mixture of the bubbles of air and the brake fluid is then delivered to a reservoir. The bubbles of air are discharged outside the reservoir, thereby purging the hydraulic booster of air completely.
