Abstract: 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.

Abstract: The present invention relates to a vehicle brake device which can secure the durability of a linear valve for controlling a servo pressure. The brake ECU of the vehicle brake device sets a reference servo pressure based on the operating amount of a brake pedal when the vehicle is stopped and sets a target servo pressure based on the reference servo pressure during one braking operation. Further, the brake ECU sets the reference servo pressure based on the operating amount of the brake pedal when the servo pressure calculated in response to the operating amount of the brake pedal exceeds the servo pressure change threshold value set with a deviation from the reference servo pressure calculated in response to the brake pedal operating amount.
