摘要： PURPOSE: To provide a hydraulic braking device for a vehicle, which can perform anti-lock control and traction control and in which a possibility that the brake liquid can not be supplied to a wheel brake is lowered. CONSTITUTION: The brake liquid of wheel brakes 16, 18 connected to one pressure generating chamber 12a of a master cylinder 12 is separately flowed to a low back pressure reservoir 20 by operating a solenoid switching valve 14a and solenoid cutting valves 14b, 14c. The brake liquid of the low back pressure reservoir 20 is flowed into the wheel brake 16 through a check valve 23 and an orifice 24, and flowed into the wheel brake 18 through a check valve 26 and an orifice 27 by a pump 21 driven by a motor 22. The solenoid cutting valves 14b, 14c are separately operated by the pump 21 so as to separately reduce or increase again the liquid pressure of wheel brakes 13, 14. At the time of the traction control, solenoid switching valves 59, 61 provided in bypass passages 58, 60 are operated.

摘要： PURPOSE:To control independently the brake liquid pressure of two vehicle wheel brakes by means of three solenoid valves end two motor-driven pumps. CONSTITUTION:When the brake liquid pressure of vehicle wheel brakes 13, 14 is reduced suddenly, the brake liquid is made to flow out to a low pressure reserver 19 by operating a solenoid changeover valve 20. Although the brake liquid of the low pressure reserver 19 is returned to the vehicle wheel brakes 13, 14 by means of motor-driven pumps 23, 24, its flow is small, and does not hinder sudden depressurization. When a solenoid cutting-off valve 21 and/or a solenoid cutting-off valve 22 are/is operated, the slow pressure increase of the vehicle wheel brake 13 and/or the vehicle wheel brake 14 is carried out by the pressure delivery of the brake liquid from the motor-driven pumps 23, 24. When the operation of the solenoid changeover valve 20, the cutting-off valves 21, 22 is released, the sudden pressure increase of the brake liquid pressure of the vehicle wheel brakes 13, 14 is carried out.

摘要： PROBLEM TO BE SOLVED: To improve the pedaling feeling by interposing a load transmitting elastic member having a set load smaller than the slide starting load of a piston and a maximum load larger than the slide starting load of the piston between the piton of a pedal stroke simulator and a brake pedal. SOLUTION: When a brake pedal 13 provided on a master cylinder 17 is operated, a stroke corresponding to the magnitude of the operating force added by a spring 19 and a pedal stroke simulator 16 is generated in the brake pedal 13. The set load Fs of the spring 19 is set smaller than a slide starting load F1 , and the maximum load Fm is set larger than F1 . According to this, the pedal stroke is generated by the elastic deformation of the spring 19 until the applied load exceeds Fs and reaches F1 , thereafter by the elastic deformation of springs 16C, 19, and finally by the elastic deformation of the spring 16C.

摘要： PROBLEM TO BE SOLVED: To surely lock a pedal stroke simulator in supplying a fluid pressure from a master cylinder to a wheel brake and to avoid high pressure in the pedal stroke simulator due to the temperature rise. SOLUTION: A pedal stroke simulator 16 is disposed inside a master cylinder 17. A fluid chamber 16B of the pedal stroke simulator 16 is connected through a normally-closed opening and closing solenoid valve 20 to a brake fluid reservoir 14. A passage 16D is provided which connects the fluid chamber 16B with the brake fluid reservoir 14 when a piston 16C of the pedal stroke simulator 16 is positioned to its return position while shielding the connection of the fluid chamber 16B and the brake fluid reservoir 14 when the piston 16C advances from the return position, thereby releasing the pressure of the fluid chamber 16B. When the pedal stroke is to be generated, a solenoid valve 20 is opened.

摘要： PROBLEM TO BE SOLVED: To reduce and stabilize braking shock at the time of starting to brake without being influenced by the driving skill of a driver. SOLUTION: At the beginning of a vehicle braking process from vehicle braking start time up to specified time Ti, target pressure Pt of a wheel brake is set to specified target pressure Ptr if basic target pressure Ptr corresponding to operating force applied to a vehicle braking operating member is in a specified area including speicified target pressure Ptr for reducing braking shock, not corresponding to the operating force applied to the vehicle braking operating member, and the target pressure Pt is set to basic target pressure Ptr if the basic target pressure Ptr is not in the specified area. At the time of switching from either one of the target pressure Pt and basic target pressure Ptr to the other, one is changed toward the other at a fixed change rate.

摘要： PROBLEM TO BE SOLVED: To change the relation of the brake pedal stamping force with the stroke in accordance with the situation of the vehicle when brakes are applied. SOLUTION: When a power-operated liquid pressure source is working normally, solenoid valves 16C and 18C are closed to shut a master cylinder 15 from wheel brakes 11 and 12. At this time, a solenoid valve 21 is opened, and a pedal stroke is generated by springs 27 and 28 which are for simulation of the pedal stroke. The stroke for the same stamping force is varied long and short by changing over the solenoid valve 12 from Open to Closed in the incremental process of the pedal stamping force. The close timing of the solenoid valve 21 is decided on the basis of the vehicle speed, advancing direction, friction factor of the running road surface, and pedal speed.
