Problems solved by technology

[0009] However, in conventional ABCS, most of the valves are electrically operated solenoid valves, thus making valve control difficult and complicated
[0010] In addition, the valve that closes the oil suction oil passage 6a under normal conditions and opens the oil suction oil passage 6a in the TCS mode is a normally closed electric slide valve 6a, so in addition to increasing the production cost of the ABCS, it is not easy to achieve the required The compactness of the hydraulic block

Embodiment Construction

[0022] Referring now to the drawings, the same reference numerals are used throughout the different drawings to designate the same or similar components. In the following description, the present invention is applied to an ABCS (Active Braking Control System), which is an electronically controlled braking system, which has an ESP circuit. The braking system of the present invention has two hydraulic circuits: a main hydraulic circuit connected to the main port 12a of the main hydraulic cylinder 12, such as figure 2 As shown, and the auxiliary hydraulic circuit connected to the auxiliary port 12b of the main hydraulic cylinder 12. These two hydraulic circuits have a symmetrical structure, so it should be understood that the drawings and the following description represent only the main hydraulic circuit.

[0023] Such as figure 2 As shown, the electronically controlled braking system of a vehicle in the main embodiment of the present invention includes a plurality of soleno...

Abstract

An electronically controlled brake system for automobiles is disclosed. In the brake system, a first check valve is mounted at an upstream position of an oil suction line which guides pressurized oil from the master cylinder to the inlet of the oil pump during a TCS mode, while a second check valve is mounted on an oil feeding line, which guides pressurized oil from the intermediate-pressure accumulator to the inlet of the oil pump through the oil suction line. The valves of both the oil suction line and the oil feeding line in the brake system are mechanically operated check valves. Therefore, the brake system of this invention is easily and simply controlled, and it is possible to accomplish the recent trend of compactness of hydraulic blocks, and reduce the production cost of the brake system.

Description

technical field [0001] The present invention generally relates to an electronically controlled braking system for automobiles, and more particularly relates to an electronically controlled braking system designed to execute ABS mode, TCS mode or ESP mode according to needs. Background technique [0002] A traditional car braking system consists of a secondary hydraulic cylinder and a main hydraulic cylinder, which generate brake oil pressure in response to the action of the brake pedal, and deliver the oil pressure to the wheel brakes, thereby reducing the speed of the car or holding the car. parking status. However, a car having such a conventional braking system may skid on a road surface due to changes in road surface conditions or oil pressure during a braking operation. [0003] To overcome this problem, various electronically controlled braking systems, such as anti-lock braking systems (ABS), traction control systems (TCS), and active brake control systems (ABCS), ha...
