Description of the invention (彳) Technical field of the invention: The present invention relates to a method of connecting a plurality of master cylinders which output hydraulic pressure to each brake operating member to a single one in response to a vehicle driver independently operating a plurality of brake operating members. Wheel brake hydraulic control device for vehicles. Conventional technology In the past, the above-mentioned brake hydraulic pressure control device is well known, for example, as disclosed in Japanese Patent Application Laid-Open No. 4 1 3 6 8 2 6 7 and the like. Problems to be Solved by the Invention The above-mentioned brake hydraulic pressure control device is a person who can brake a wheel brake installed on a front wheel even if any one of a plurality of brake operating members is operated, but controls the brake hydraulic pressure with anti-lock control. In order to achieve extremely fine control, it is expected that a control valve mechanism may be provided to independently control the hydraulic pressure between each master cylinder and a common wheel brake. However, when the brake hydraulic pressure control of a wheel brake is performed, in order to fully operate the control valve mechanism related to the wheel brake, the following problems may occur. That is, in a state where only a part of the plurality of brake operating members is operated, the brake hydraulic pressure of the wheel brake is controlled by anti-lock control and the like. When the other brake operating members are re-operated, the brake hydraulic member will be affected by the brake hydraulic control. It will prevent re-operation of the brake operating member. In spite of this, when the brake operating member is re-operated, until now, an additional input is formed for wheel brakes controlled by hydraulic pressure, which will cause confusion in the hydraulic control of the wheel brakes. Due to the action of the control valve mechanism that does not need to be operated, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). --- Γ-(Please read the precautions on the back before filling this page) Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperatives -4- 491783 A7 —__ B7 V. Description of Invention (2) The problem of increased power consumption and reduced durability. The present invention was created in view of the above-mentioned problems, and an object thereof is to provide a vehicle brake hydraulic pressure control device, which is provided with independent control valve mechanisms between a plurality of main cylinders and wheel brakes, so as to improve the brake hydraulic pressure. Controls the fineness and density, and solves the problems that occur when the operation of the multiple brake operating members is performed in stages. It can avoid the increase in power consumption and achieve the durability of the lift control valve mechanism. Solution to Problem In order to achieve the above object, the present invention provides a brake hydraulic pressure control device for a vehicle, in which a plurality of master cylinders outputting hydraulic pressure of each brake operating member are connected to a single one because a driver of the vehicle can independently operate a plurality of brake operating members. Vehicle brake hydraulic pressure control device for wheel brakes is provided with a control valve mechanism for independently setting the brake hydraulic pressure acting on the front wheel brakes on each of the main cylinders and the front wheel brakes, and detecting each of the brakes individually The detection mechanism for the operation of the operation member, and each control valve mechanism is operated by hydraulic control only when the brake operation member corresponding to each control mechanism is detected by the detection mechanism. According to the above-mentioned configuration, control valves are provided independently of each other between the plurality of main cylinders and the wheel brakes, and extremely fine control is performed when the brake hydraulic pressure is controlled by back-lock control or the like. However, since each control valve mechanism can only perform hydraulic control when the detection mechanism detects a brake lever corresponding to the control valve mechanism, the brake hydraulic pressure of the wheel brake is controlled only by operating a part of the components of the brake lever.

Description of the invention (6) It is located between the normally open solenoid valve 5 C and the normally closed solenoid valve 13 and the fuel tank 10 A. This control valve mechanism VC is also the same as the above-mentioned control valve mechanisms VA and VB. 'Choose one of three states to control the pressure increase, pressure maintenance, and pressure reduction of the crucible 12, and the solenoid valve 5 C can be cyclically controlled. 7 C cut-off. The opening sequence of the above-mentioned normally-closed solenoid valve 13 is controlled by a control device (not shown). The control device inputs a detection mechanism 1 4 A, 1 for detecting the output hydraulic pressure of each of the main cylinders 2 A and 2 B. 4 B detection 値. The control device operates the brake lever 1 A, and responds to the normally-closed solenoid valve 13 by opening the normally-closed solenoid valve in response to the hydraulic pressure detected by the detection mechanism 1 4 A exceeding the set hydraulic pressure. 1 3 to control. In addition, the control device detects detection pressures 1 4 A and 1 4 B of the hydraulic pressure output from the master cylinders 2 A and 2 B in accordance with the operations of the brake levers 1 A and 1 B to control the control valve mechanisms.

Description of the invention (7) 1 2 are closed by normally closed solenoid valve 1 3, so the rear wheel brake BR is used to brake first, and then the front wheel brake BF is used again. The brake action is performed to stabilize the movement of the vehicle body. Since the control valves VC and VB are provided independently of each other between the main cylinders 2A, 2 B and the front wheel wheel brake BF, therefore, they are locked by back-locking. When controlling the brake hydraulic pressure such as control, very fine control can be performed. However, due to each control valve mechanism VC, the VB system detects only when the detection mechanism 1 4 A, 1 4 B corresponds to the control valve mechanism VC, VB. When the brake levers 1 A and 1 B are hydraulically controlled and actuated, part of the brake levers 1 A and 1 B, for example, when only 1 B is operated, the brake hydraulic pressure of the front wheel wheel brake BF is controlled. When the lever 1 A is operated, it does not affect the hydraulic control on the side of the lever 1 A, so the lever 1 A can be easily operated. Moreover, even if the lever 1 A is re-produced, the control valve mechanism VC corresponds to the existing The operating brake lever 1A operates hydraulically, so that the hydraulic control of the front wheel wheel brake BF is not disturbed.
