CONTROL APPARATUS FOR HYDRAULIC COMPONENTS OF A BRAKING SYSTEM OF A VEHICLE, AND METHOD FOR EXECUTING AN ANTILOCK BRAKING FUNCTION AT AT LEAST ONE WHEEL BRAKE CYLINDER OF A VEHICLE

摘要

A control apparatus for hydraulic components of a braking system of a vehicle, having a control application device that is designed to establish by application of control to the hydraulic components, in consideration of the braking request, at least one brake pressure in at least one wheel brake cylinder in such a way that the braking request is satisfiable; and to execute an antilock braking function at the at least one wheel brake cylinder, the control application device additionally being designed to ascertain whether at least one furnished actual value with regard to a displacement travel (s) of a brake actuation element of the vehicle out of its initial position, and/or with regard to a simulator volume shifted out of a brake master cylinder of the vehicle into a linked simulator, lies within at least one predefined extreme value range.

主权项

1. A control apparatus for hydraulic components of a braking system of a vehicle, comprising:
a control application device that is designed to:
detect, on the basis of at least one furnished braking request signal, a braking request of a driver of the vehicle; andby application of control to the hydraulic components in consideration of the braking request, at least to set at least one brake pressure in at least one wheel brake cylinder of the braking system in such a way that the braking request is satisfiable by a total braking torque made up at least of at least one wheel brake cylinder braking torque of the at least one wheel brake cylinder; andexecute an antilock braking function at the at least one wheel brake cylinder by the fact that the respective brake pressure in the at least one wheel brake cylinder is held constant or reduced, despite the higher braking request in relation to the respective brake pressure, in such a way that the braking request is satisfied only partly by the total braking torque; wherein the control application device is additionally designed to:
ascertain whether at least one furnished actual value at least one of: i) with regard to a displacement travel of a brake actuation element of the vehicle out of its initial position, and ii) with regard to a simulator volume shifted out of a brake master cylinder of the vehicle into a linked simulator, lies within at least one predefined extreme value range; andif the at least one furnished actual value lies within the at least one extreme value range, transfer a brake fluid volume out of at least one of: i) the at least one wheel brake cylinder and ii) at least one reservoir device, and into the brake master cylinder during the antilock braking function executed simultaneously or thereafter, by application of control to the hydraulic components.
