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： This is a new brake system for minimizing the turning radius of a vehicle when it makes a U-turn or parks. The minimum turning radius of a conventional vehicle has a certain limit because a conventional vehicle takes the Ackerman-Jeantaud steering principle. The object of this invention is to overcome the limit of the minimum turning radius by introducing the new concept, the one wheel brake system. This invention utilizes the phenomenon that if one wheel is braked, the other wheel is driven by the differential gear. Hence the vehicle circles around a braked wheel as its pivot. So it turns much smaller than the minimum turning radius of the Ackerman-Jeantaud steering angle.

摘要： A hydraulic brake apparatus for a vehicle includes a supplementary hydraulic pressure source outputting a pressurized output hydraulic pressure and an electronic control apparatus that controls a hydraulic pump in the supplementary hydraulic pressure source. The electronic control apparatus judges whether the hydraulic pump satisfies a predetermined operating condition based on the output hydraulic pressure of the supplementary hydraulic pressure source or not. The electronic control apparatus compares the output hydraulic pressure with a minimum standard hydraulic pressure, detects a drop in the output hydraulic pressure when the output hydraulic pressure is less than a standard hydraulic pressure and determines that the hydraulic pump does not satisfy the predetermined operating condition.

摘要： In a braking pressure intensifying master cylinder, as an input shaft (53) travels forwards in a braking maneuver, a control valve (54) is actuated to develop fluid pressure according to the input in a reaction chamber (38) and a pressurized chamber (35). A stepped spool (45) as a part of the control valve 54 travels such that force produced by the fluid pressure and spring force of a spring (51) are balanced, whereby the stepped spool (45) can function as a travel simulator. By changing the pressure receiving areas of the stepped spool and/or changing the spring force of the spring (51), the travel characteristic of the input shaft (53) as the input side can be freely changed independently from the output side, without influence on a master cylinder pressure as the output side of the braking pressure intensifying a master cylinder (1). In addition, the master cylinder pressure can be intensified when necessary with a simple structure.

摘要： In a brake booster of the present invention, by depression of a brake pedal 3, an input shaft 4 travels to the left, a pedal input converter generates thrust, and a valve element 5a moves to the left. A valve passage 5a1 is shut off from a valve passage 5b1 and a valve passage 5a2 is connected to a valve passage 5b2 so as to develop output pressure Pr at an output port 5c of a control valve 5 because of the pressure of a pressure source. The output pressure Pr is supplied to a wheel cylinder 7, thereby actuating the brake. At this point, since the displacement of the input shaft 4 required for operating the control valve 5 is defined only by the converter 6, the input side is not affected by the brake rigidity of a circuit from the control valve 5 to the wheel cylinder 7. The output pressure Pr of the control valve 5 acts on the valve element 5a through a first reaction receiving portion 8 and is regulated to pressure proportional to the thrust of the converter 6. The second reaction force is transmitted to a driver through a second reaction receiving portion 9. The control of the output can be conducted during the operation regardless of the input of the input side and the respective characteristics can be varied without being affected by the output side.

摘要： A hydraulic brake apparatus for a vehicle comprises a master cylinder and an auxiliary hydraulic pressure source. A master cylinder hydraulic pressure outputted from the master cylinder is adjusted by adding a master cylinder hydraulic pressure in response to an operation of a brake operating member to a master cylinder hydraulic pressure at an auto-braking control when the brake operating member is operated during the auto-braking control. The master cylinder hydraulic pressure is adjusted by controlling an operation of a valve means so as to increase a power hydraulic-pressure supplied from the auxiliary hydraulic pressure source to a regulating means corresponding to the amount of the operation of the brake operating member.

摘要： The present invention is directed to a brake control system, which includes wheel brake cylinders, a master cylinder, a reservoir communicated with the wheel brake cylinders, normally open solenoid valves disposed between the master cylinder and the wheel brake cylinders, respectively, normally closed solenoid valves disposed between the wheel brake cylinders and the reservoir, respectively, a hydraulic pump for supplying the brake fluid to a passage for connecting the master cylinder with the normally open valves, and an automatically pressurizing device (e.g., a vacuum booster with a changeover valve) which is provided for advancing the master piston irrespective of operation of the pump and the brake pedal to generate hydraulic braking pressure from the master cylinder. It is so controlled that a distance of the master piston, which is advanced by the automatically pressurizing device when all of the normally open valves are closed during the hydraulic pressure control of the wheel brake cylinders, is greater than the distance of the master piston, which is advanced by the automatically pressurizing device when at least one of the normally open valves is open during the hydraulic pressure control of the wheel brake cylinders.
