Problems solved by technology

However, in this integrated structure, it is difficult to design an alternative solution combined with hydraulic system, such as electromechanical brake actuator combined with hydraulic system
[0004] In the prior art, the solution described in CN108162940 requires the master cylinder integrated in the electro-hydraulic booster to be provided with two chambers, causing unnecessary additional costs, because the redundancy provided by the electro-mechanical actuator is already sufficient
In addition, the ECU needs to additionally control the electro-mechanical brake, which limits the use of different actuation methods for non-hydraulic components
[0005] The method described in DE10319194 has no obvious cost savings on hydraulic components, because the complete set of electrohydraulic equipment follows the traditional system, while the cost increase on electromechanical components is obvious
