Abstract: A hydraulic brake device is provided with a master cylinder for supplying pressurized fluid to plural brakes which respectively restrict the rotations of road wheels, a solenoid block mounted on the master cylinder and containing plural solenoid valves, and an ECU provided with a control board for controlling the solenoid valves to distribute pressurized fluid to the plural brakes and also provided with a case for containing the control board therein. The solenoid block and the ECU are constructed to be an integrated structure, and the integrated structure composed of the solenoid block and the ECU is removably mounted on the master cylinder. Further, the ECU is secured to the solenoid block by means of screw bolts which are arranged within an area insider the external form of the control board. Thus, it becomes unnecessary to provide bolt seats for the screw bolt outside the case, so that the case and hence, the ECU can be miniaturized. Further, for replacement of the control board, the integrated structure is removed from the master cylinder and is replaced with a new one as a part, instead of disjoining the control board per se from the ECU to replace the control board with a new control board as a part. Thus, it can be avoided that the reliability of the ECU is deteriorated due to disjoining the control board and rejoining the new control board.

Abstract: It is aimed to improve reliability of a hydraulic brake device which is capable of regenerative cooperative control, and also to eliminate wasteful consumption of electric power. Hydraulic pressure supplied from a hydraulic pressure generating device is adjusted to a value corresponding to the brake operating force by a pressure adjusting valve. A master cylinder is activated under the hydraulic pressure supplied to an auxiliary hydraulic chamber. The output hydraulic pressure of the master cylinder and the pressure adjusting valve is supplied to wheel cylinders to impart braking force to vehicle wheels. A hydraulic pressure adjusting device is provided to adjust the hydraulic pressure in the auxiliary hydraulic chamber to a desired hydraulic pressure value that is above the output hydraulic pressure value of the pressure adjusting valve. During regenerative cooperative control, the output hydraulic pressure of the pressure adjusting valve is supplied to the auxiliary hydraulic chamber as it is, and during non-regenerative cooperative control, the output hydraulic pressure of the pressure adjusting valve is increased corresponding to regenerative braking force and supplied to the auxiliary hydraulic chamber.

Abstract: An electric parking brake control unit of an electric parking brake apparatus has an input section for receiving signals for performing automatic activation and deactivation, but does not have a determination function and a circuit for inputting signals from various sensors, which are necessary to determine whether to start the automatic activation/deactivation control. Therefore, when used in a vehicle which does not require an automatic control function and requires only a manual control function, the electric parking brake control unit can be used solely, with no signal line connected to the input section. When used in a vehicle which requires both the automatic control function and the manual control function, the input section is connected to a second control unit that can output signals for performing automatic activation and deactivation, whereby the electric parking brake control unit operates in cooperation with the second control unit.

Abstract: A bellows-type hydraulic accumulator includes a shell, a bellows unit, and a stay in order to accumulate pressurized liquid within a liquid chamber, divided into a fixed-volume liquid chamber and a variable-volume liquid chamber communicating with the fixed-volume liquid chamber via a communication port formed in the stay. A pipe is inserted into a liquid inlet/outlet port communicating with the fixed-volume liquid chamber, to thereby form an inflow passage inside the pipe and an outflow passage outside the pipe. A tip end of the pipe is located within the communication port of the stay with a predetermined radial clearance formed between the tip end and a wall surface of the communication port, to thereby enable pressurized liquid to be supplied to the variable-volume liquid chamber from the tip end of the pipe and to be discharged from the variable-volume liquid chamber to the fixed-volume liquid chamber via the radial clearance.

Abstract: A wedge-operated brake apparatus includes a piston for generating a braking force when axially driven, an actuator for generating a linear brake-actuating input, and a wedge transmission mechanism for converting the linear brake-actuating input into a brake-actuating output in the axial direction of the piston. The brake-actuating output is transmitted to the piston so as to drive the piston to thereby generate a braking force. The wedge transmission mechanism includes a first plate member which moves together with the piston, a second plate member disposed in opposition to the first plate member and fixedly secured to a housing, a wedge member disposed between the first and second plate members and engaging respective engaging surfaces of the first and second plate members via rollers, and a holder for rotatably holding the rollers and holding the wedge member while allowing linear movement of the wedge member. When the wedge member moves linearly, the holder moves, while being guided by the first and second plate members.

Abstract: A master cylinder includes a cylinder housing having a cylinder bore, a seal cup disposed inside the cylinder bore, and a piston slidably disposed in the cylinder bore in sliding contact with the seal cup and defining a pressure chamber in cooperation with the housing and the seal cup. The piston includes a connecting passage which fluidly connects the pressure chamber with an atmospheric pressure chamber when the piston is in a retracted position. The seal cup cuts off fluid communication between the pressure chamber and the atmospheric pressure chamber through the connecting passage when the piston moves in its axial direction by a prescribed distance from its retracted position. The connecting passage is a stepped hole having a first end portion with a small diameter which communicates with the pressure chamber and a second end portion with a large diameter which opens onto an outer peripheral surface of the piston. The cross-sectional area of the first end portion is such as to produce a throttling effect.

Abstract: It is proposed to improve the operating feeling of a vehicle brake hydraulic pressure generator in which the hydraulic pressure supplied from a hydraulic pressure source is adjusted to a value corresponding to the brake operating force by means of a pressure adjusting valve which changes its operating state according to displacement of an input piston or a simulator piston. A simulator chamber in the piston into which the simulator piston protrudes is connected to an atmospheric reservoir through an orifice to restrict the flow of brake fluid out of the simulator chamber while the brake is operated sharply, ther by delaying the stroke of a brake pedal.

The ventilation passage includes: a first ventilation passage extending from the internal space in a predetermined direction so as to include a bottom portion; and a second ventilation passage extending from the outside in a direction intersecting the predetermined direction. The first ventilation passage and the second ventilation passage communicate with each other by allowing the bottom portion to communicate with the bifurcated portions provided at an end portion of the second ventilation passage. A portion where the first ventilation passage and the second ventilation passage communicate with each other is narrowest in the ventilation passage.

Abstract: A vehicle controller sets an upper limit request value related to an upper limit of a longitudinal acceleration of a vehicle, a lower limit request value related to a lower limit of the longitudinal acceleration, and an acceleration request value related to the longitudinal acceleration that corresponds to an amount of the operation of the vehicle. The vehicle controller sets a first arbitration request value to a greater one of the lower limit request value and the acceleration request value. The vehicle controller sets a second arbitration request value to a smaller one of the first arbitration request value and the upper limit request value. The vehicle controller sets, to a value that corresponds to the second arbitration request value, a command value sent to an actuator that operates to adjust the traveling speed.
