Electric Brake Redundancy Control Apparatus

The patent replaces the purely mechanical brake pedal operation with an electrically assisted system. A motor is activated during fallback mode to provide auxiliary braking force, substituting mechanical driver effort with electromechanical assistance. This allows the braking function to remain reliable while significantly reducing the physical force the driver must apply to the brake pedal.

The patent introduces a motor as an intermediary between the driver's brake pedal input and the braking system. The motor acts as a mediator that amplifies the driver's input force, enabling the fallback braking function to operate with reduced driver effort while maintaining system reliability during abnormalities.

The patent segments the hydraulic circuit into distinct functional zones with isolated abnormality containment. By dividing the circuit into separate segments with individual control valves, the system can isolate faults to specific segments while maintaining operation in other segments, improving reliability without requiring a completely complex reconfiguration of the entire hydraulic system.

The patent designs hydraulic circuit components to serve multiple functions. Valves and passages are configured to handle both normal operation and fallback mode requirements, as well as abnormality isolation, within a unified circuit structure. This multi-functionality reduces the need for separate dedicated components for each function, thereby improving reliability while controlling overall device complexity.

The patent merges multiple valve functions into integrated valve assemblies or combined control units. By consolidating flow control, pressure regulation, and isolation functions into fewer multi-functional valve components, the system maintains precise hydraulic flow control while reducing the total number of discrete valves, thereby improving system compactness and reducing overall system volume.

The patent employs nested valve configurations where smaller control valves are integrated within or alongside larger main valves. This nesting arrangement allows multiple flow control functions to be achieved within a compact footprint, maintaining measurement precision for hydraulic control while minimizing the space occupied by the valve assembly and improving overall system compactness.
