What are the advantages of EHB compared with traditional braking system?

Electro-hydraulic braking system (EHB) is developed on the basis of traditional hydraulic braking. The control mechanism replaces the traditional hydraulic brake pedal with an electronic brake pedal and cancels the huge vacuum booster. This integrated electronic pedal sensor can accurately sense the priority of the driver's pedal control, and convert it into an electrical signal to be transmitted to the electronic control unit, and the high-pressure hydraulic control unit will automatically adjust the brake pressure of the wheel according to different driving conditions. The system shortens the reaction time and avoids the danger that the driver unconsciously reduces the braking force due to the vibration caused by the reaction of the hydraulic mechanical braking system. The actuator uses a comprehensive brake module to replace the pressure regulator and ABS module in the traditional brake. This comprehensive braking module includes motor, pump, battery and other components, which can generate and store braking pressure and adjust the braking torque of four tires respectively. Compared with the traditional hydraulic brake, EHB has made remarkable progress:

Main advantages

(1) Compact structure, improved braking efficiency;

(2) The control is convenient and reliable, and the braking noise is significantly reduced;

(3) No vacuum device is needed, which effectively reduces the recoil of the brake pedal and provides a better pedal feeling;

(4) Due to the improvement of modularity, the design flexibility in the vehicle design process is improved, the number of parts of the braking system is reduced, and the layout space of the braking system in the vehicle is saved. The limitation of EHB is that the whole system still needs hydraulic components and cannot do without brake fluid.

EH B is developed on the basis of traditional hydraulic brake. Different from the traditional automobile braking system, EH B is an advanced mechatronics system, in which some mechanical components are replaced by electronic components. EHB replaces the pressure regulator and ABS module in traditional brakes with comprehensive brake module. This comprehensive braking module consists of motor, pump, battery and other components. It can generate and store braking pressure, and can independently adjust the braking torque of four wheels. At the same time, the corresponding program is designed in the electronic control system of EHB, and the braking force is controlled by manipulating the electronic control components, so that the functions of ABS and ASR can be fully realized.
