Description

Technical Field

[0001] The utility model relates to the technical field of automotive braking, and particularly relates to a valve block for a hydraulic decoupling electronic braking system. Background Art

[0002] The hydraulic decoupling electronic braking system (DHB) realizes the braking function through an electronic control unit (ECU) and a hydraulic actuator. Specifically, when the driver steps on the brake pedal, the pedal force sensor converts the pedal displacement into an electrical signal and inputs it into the ECU. The ECU calculates the required braking force based on the received signal and other vehicle state information, and controls the operation of actuators such as motors and solenoid valves. The system drives a hydraulic pump through a motor to generate hydraulic pressure, and through the precise control of the solenoid valve, transmits the hydraulic pressure to the brake wheel cylinder, thereby realizing the braking of the vehicle. Since the system realizes the decoupling between the brake pedal and the brake actuator, the braking response is faster, and at the same time, the energy recovery efficiency is improved.

[0003] In the related art, the control of the hydraulic decoupling electronic braking system is mainly realized through various control valves installed on the hydraulic valve block. As an important part of this system, the structure and performance of the valve block directly affect the performance of the entire braking system. However, the existing valve block has a complex structure, a large volume, inconvenient installation, and the connection between each channel is not optimized enough, resulting in limited response speed and control accuracy of the braking system.
