Electromechanical Brake Fluid Reference Control Under Variable Conditions

The patent implements dynamic adjustment of the required fluid amount reference based on vehicle conditions. The controller continuously monitors vehicle speed, deceleration, and temperature, then dynamically updates the required fluid amount reference accordingly. This transforms the static reference value into a dynamic parameter that adapts to changing operating conditions, resolving the contradiction between simple structure and reliable performance.

The system establishes a feedback loop where the controller monitors actual vehicle conditions (speed, deceleration, temperature) and compares them against stored maps to determine the appropriate required fluid amount reference. This feedback mechanism ensures brake control performance maintains reliability across varying conditions while using a relatively simple implementation approach.

The patent pre-stores multiple maps containing required fluid amount references corresponding to different vehicle conditions (speed, deceleration, temperature ranges). When operation begins, the controller directly retrieves the appropriate reference value from the pre-stored maps based on current conditions, rather than calculating it in real-time. This preliminary preparation significantly reduces response time while maintaining high measurement precision.

The system monitors vehicle conditions continuously but only updates the required fluid amount reference when actual conditions deviate beyond predetermined thresholds from the current reference. This partial action approach avoids unnecessary adjustments and calculations during stable operating conditions, reducing overall processing time while maintaining accuracy when conditions actually change.
