摘要： An automatic brake booster includes a solenoid which drives a plunger, forming part of a valve mechanism, forward to switch a flow path in the valve mechanism, separately from an input shaft. A piston is mounted on the plunger, and the atmospheric pressure is introduced into an atmospheric pressure chamber disposed forwardly of the piston while a pressure which prevails in constant pressure chambers A, C is introduced into a negative pressure chamber disposed rearwardly of the piston, thus urging the piston rearward. Preferably, the piston has a pressure responsive area which is substantially equal to the pressure responsive area of an atmosphere valve seat formed on a plunger. This arrangement allows a variation in the output from the brake booster to be minimized or reduced substantially to zero if there is a variation in the magnitude of a negative pressure which is introduced into the constant pressure chambers A, C.

摘要： A brake booster which permits an axial relative movement between a power piston and a valve body is disclosed. An arrangement is made which prevents a brake reaction from being transmitted to a brake pedal. As an alternative therefor, pseudo-reaction imparting means transmits a pseudo-reaction to a brake pedal. A rear end of the valve body is covered by a tubular cover and bellows connected thereto, and its internal space is maintained in communication with a constant pressure chamber. The bellows has an effective diameter which is chosen to be of an equal size to the diameters of a vacuum valve seat and an atmosphere valve seat. This allows a pseudo-reaction and a brake pedal stroke to be obtained which depend on the force with which a brake pedal is depressed if a negative pressure within the constant pressure chamber varies, thus imparting a better brake feeling to a driver.

摘要： A fluid pressure boosting device of the present invention performs jumping action at a higher servo ratio until fluid pressure in a power chamber (25) reaches a first predetermined value and a rear end (20e) of a reaction piston (20)comes in contact with a step of an input shaft (18). Since a switching valve is set in a first position I until the fluid pressure in the power chamber (25) reaches a second predetermined pressure, a reaction chamber (41) is connected to the reservoir (33) so as to be at atmospheric pressure. In this state, the normal brake control at a lower servo ratio is performed. As the fluid pressure in the power chamber (25) reaches a second predetermined value, the switching valve is set in a second position II by the fluid pressure so that the pressurized fluid in the power chamber is introduced into the reaction chamber (41). The fluid pressure in the reaction chamber 41 acts on the step between the reaction piston (20) and the input shaft (18) so that the servo ratio becomes higher. Then, the servo control at a higher servo ratio is performed. The fluid pressure boosting device can be provided with the reversed two-stage servo characteristic, so with simple structure, output larger than the normal output can be obtained when input exceeds a predetermined value.

摘要： A brake system has wheel cylinders for producing a braking force in wheels using pressurized brake fluid transmitted through a main conduit from a master cylinder, a reservoir for storing brake fluid, a sideslip preventing device for when a sideslip state of the vehicle is detected supplying brake fluid to the wheel cylinder corresponding to a sideslip controlled wheel and producing a braking force in the sideslip controlled wheel, a first conduit used for supplying brake fluid from the reservoir to the wheel cylinders by the pump and a first valve for switching this first conduit between an open state and a closed state. The sideslip preventing device, when the sideslip state is detected during non-braking of the vehicle, makes the first valve open-state and thereby conducts supply of brake fluid through the first conduit from the reservoir to the wheel cylinder by a pump. When the sideslip state is detected during braking of the vehicle, the sideslip preventing device makes the first valve device closed-state and thereby prohibits supply of brake fluid from the reservoir to the wheel cylinder.

摘要： In an obtainer for obtaining speed feeling of a driver of a movable object, a gaze point setter sets a gaze point of the driver, and a motion detector detects relative motion of an environmental field around the mobile object with respect to the mobile object. A divergent component calculator projects the relative motion of the environmental field in a coordinate system. The coordinate system is formed by modeling a retina sphere of the driver of the mobile object. The divergent calculator calculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point. A speed feeling calculator calculates speed feeling of the driver based on the divergent components of the projected relative motion of the environmental field radially expanding from the gaze point calculated by the divergent component calculator.

摘要： A vehicle control system calculates driver-required wheel torque, correction wheel torque to stabilize vehicle motion, required output shaft torque, alternator base torque, target engine torque and alternator torque to realize the output shaft torque. The required output shaft torque is required to realize vehicle motion, and the alternator base torque is required to maintain amounts of electric power in batteries. In order to realize the torque including wide band frequency torque, a torque division unit divides the sum of the torque into each torque actuator response frequency torque. Therefore, the target alternator torque is calculated by the alternator base torque to maintain electric power in batteries and high frequency band torque required by vehicle motion control.

摘要： In a driving condition control system, a sensing unit senses a first physical quantity indicative of a rotation of the first rotatable axle assembly and a second physical quantity indicative of a rotation of the second rotatable axle assembly. A determining unit compares the first and second physical quantities of the rotations of the first and second rotational axle assemblies and determines whether a driving condition of the vehicle is unstable according to the compared result. As a result, the unstable condition of the vehicle can be rapidly detected without detecting a yaw moment of the vehicle.

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.
