摘要： PROBLEM TO BE SOLVED: To adjust a reaction force applied to the lever of an operating device that commands braking and driving forces through lever operation. SOLUTION: The column 14 of a lever is pivotally supported by a joint so that the lever can tilt in all directions. A sponge member 18 is disposed so as to surround the column 14 of the lever. The column 14 is energized toward a neutral position from all directions by the sponge member 18. A pair of storage members 22 are opposed to each other across the column 14 along a specific direction in which the lever is tilted, so that they receive the column 14 that will fall down when the lever is tilted in the specific direction. A spring 20 is attached to the back of each storage member 22 opposite to the column of the lever. The spring 20 is oriented in the specific direction and applies a reaction force to the lever via the storage member 22. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To smoothly control a brake cylinder liquid pressure while suppressing cost increase. SOLUTION: The brake cylinders 52, 54, 60, 62 at front and rear sides and left and right sides are connected to a main passage 160 and a hydraulic power source 64 is connected through a power passage 100. A boosting solenoid linear valve 230 is provided on the power passage 100. Further, a pressure-reduction control valve 182 provided corresponding to the brake cylinder 52 is made to a linear valve. The liquid pressures of all brake cylinders 52, 54, 60, 62 are commonly controlled by control of the boosting solenoid linear valve 230 and the pressure-reduction solenoid linear valve 182. Since it is not performed by opening/closing control of a solenoid opening/closing valve, the liquid pressure of the brake cylinder can be smoothly varied. Further, since the linear valve is not provided in every wheel, cost increase can be suppressed. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：在抑制成本增加的同时平稳地控制制动液缸液压。解决方案：前后侧和左侧和右侧的制动缸52,54,60,62连接到主通道160，并且液压动力源64通过动力通道100连接。升压螺线管线性阀230设置在动力通道100上。此外，对应于制动缸52设置的减压控制阀182被制成线性阀。所有制动缸52,54,60,62的液体压力通常通过控制升压螺线管线性阀230和减压螺线管线性阀182来控制。由于不是通过打开/关闭螺线管开度关闭阀，制动液压缸的液压可以平稳地变化。此外，由于在每个车轮中不设置线性阀，因此可以抑制成本增加。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an electronically controlled hydraulic brake system capable of restraining transmission of pulsation from a confluence point of a front decompression passage and a rear decompression passage to the rear decompression passage in releasing a pedal.
SOLUTION: The front decompression passage 74 to connect a decompression linear valve 76 and a reserver 52 to each other and the rear decompression passage 76 to connect a decompression linear valve 80 and the reserver 52 to each other are made independent from each other. For example, the rear decompression passage 78 is connected to the middle of a suction passage 60 and the front decompression passage 74 is directly connected to the reserver 52. Additionally it is possible to provide a check valve or a damper device at a part on the side of the decompression linear valve from the confluence point of the rear decompression passage on the brake system of a form to connect to the reservoir after the front decompression passage and the rear decompression passage join. It is possible to restrain transmission of pulsation even when working of the rear decompression linear valve 80 is prohibited until front hydraulic pressure is lowered or the decompression linear valve 76 is controlled so as to restrain front decompression gradient.

摘要： PROBLEM TO BE SOLVED: To effectively utilize a normal braking device while keeping the steering stability of a vehicle favorable when abnormality occurs on at least one main braking device in a brake controlling device for which both of the main braking device and a subsidiary braking device are provided on one wheel. SOLUTION: When an abnormality occurs on a service braking device (the judgement of S71 is YES), a parking brake is operated (S73), and at the same time, whether the absolute value of a yaw rate is a set value or higher or not is judged (S74). When the absolute value is the set value or higher (the judgement of S74 is YES), the braking force of the normal service braking device is controlled (S75). Thus, a difference between the right and left braking forces can be suppressed, and the steering stability of the vehicle is avoided from being spoiled, and the normal service braking device can effectively be utilized.

摘要： PROBLEM TO BE SOLVED: To effectively utilize a normal electric braking device while the steering stability of a vehicle is kept favorable when abnormality occurs on at least one of the electric braking devices in the brake controlling device which controls a plurality of the electric braking devices. SOLUTION: When a wheel which corresponds to an abnormal electric braking device is a turning internal wheel, even if a right and left brake force difference occurs, a yaw moment generated resulting from the brake force difference faces a direction to suppress spinning, and the steering stability is not spoiled. Therefore, the braking force for a turning external wheel is made larger. On the contrary, when the wheel which corresponds to the abnormal electric braking device is a turning external wheel, the braking force for the turning internal wheel is made smaller. Thus, the normal electric braking device can effectively be utilized while keeping the steering stability favorable. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vehicle with a countermeasures device against the sound emitted by the operation of an operating device in the countermeasures against the sound of the operating device such as a pump device and a control valve. SOLUTION: In a hybrid vehicle to be selectively driven by an engine and front and rear motor generators, the initial check of a master cut valve and a simulator communication valve of a liquid pressure brake device and a pump device is performed after the operation of the engine, or when the set time is elapsed without any operation of the engine, or when the traveling speed of a vehicle is equal to or greater than the set value, the engine is operated to perform the initial check. The operating sound of the master cut valve or the like is mixed with the operating sound of the engine, and the initial check is performed without any sense of incongruity of an occupant. During the normal traveling, the master cut valve and the simulator communication valve are operated at least in one state in which the engine speed is equal to or higher than that of the set value, and the traveling speed of the vehicle is equal to or higher the set value, and the pump device is operated when the engine is operated.

摘要： PROBLEM TO BE SOLVED: To detect air presence/absence in a brake system while reducing energy consumption in a hydraulic brake device.
SOLUTION: Communicating brake cylinders 20,21 of front left/right wheels with a master cylinder 12 stores working fluid of the master cylinder 12 in the brake cylinders 20,21. Then, master blocking valves 29,30 are made to be a closing status, boosting linear valves 150-152 are made to be opening statuses, and a pressure reduction linear valve 162 is made to be a closing status. The brake cylinders 20,21,22 are communicated with each other to have the same hydraulic pressures. When the hydraulic pressure is higher than a first hydraulic pressure for air presence/absence detection, the air is determined to be absent in a second braking system 232. When the hydraulic pressure is as low as or lower than the first hydraulic pressure for air presence/absence detection, the air is determined to be present. Not using a power type hydraulic pressure source 14 but using the working fluid of the master cylinder 12 can reduce the energy consumption at the time of detecting air presence/absence.

摘要： PROBLEM TO BE SOLVED: To detect brake torque on the basis of liquid pressure by generating liquid pressure complying with a friction force. SOLUTION: When braking is applied while a disc rotor 10 rotates in the regular direction, a friction force is generated between a frictional engagement member and the rotor 10, and calipers 14 are rotated in the regular direction. In a hydraulic cylinder 51, accordingly, a piston 54 is advanced against the energizing force of a return spring 66 to cause a decrease in the capacity of a liquid pressure chamber 64, and thereby the liquid pressure is generated. Because the liquid pressure has a magnitude in compliance with the braking force between the frictional engagement member and the rotor 10, the braking force can be determined on the basis of the liquid pressure, and the brake torque can be detected by multiplying the braking force by the radius of the position where the frictional engagement member is mounted on the rotor 10.

摘要： PROBLEM TO BE SOLVED: To allow a brake control device for controlling a plurality of electric brake devices to make effective use of the normal electric brake devices while keeping the stability of vehicle control good when there is an abnormality in at least one of the electric brake devices. SOLUTION: When an abnormality in the electric brake device for the left front wheel is detected, determination is made based on the running state of the vehicle as to whether actuation of the electric brake device for the right rear wheel is inhibited or permitted. When the running state is not on the stable side of a set condition, actuation of the electric brake device for the right rear wheel is inhibited; when the running state is on the stable side of the set condition, actuation is permitted because the vehicle is determined to be in such a state that the stability of control can be kept almost good even if the difference between right and left braking forces is increased. Even if there are abnormal electric brake devices, the normal electric brake devices can be used effectively and a decrease in the braking forces of the entire vehicle can be avoided.
