ABSTRACT:
A process and system for attaining a desired braking value is disclosed. The actual braking value is adjusted until the desired braking value is attained. Conventionally the braking hysteresis worsens the response of a brake and, thereby, worsens the quality of the regulation of a braking system with regulated braking value. Known processes reduce the brake application energy in steps if the actual braking value is too great until the braking hysteresis has been overcome and the desired braking value has been attained. Whereas, the present invention decreases the brake application energy ZS by a value (HyS+W) consisting of the braking hysteresis HyS associated with the desired braking value and a effect drop-off W. This decrease occurs in the case of excessive actual braking value BI. The process accelerates the attainment of the desired braking value BS. The preferred area of application for the invention are braking systems in the automotive industry.
