A method for controlling the braking action applicable by a brake caliper on a mechanical movement member of a vehicle is described. An electronic control unit operatively connected to an actuator assembly receives an input signal representative of a braking request. The unit determines a first reference value of a position of a component in the actuator assembly and a second reference value of a parameter representative of the braking action applicable by a brake caliper via the actuator assembly. The unit determines at least one feedback value of the position of a component in the actuator assembly. The unit also generates at least one control signal for the actuator assembly based on feedback values and the reference values.

A compensation control system is provided for preventing braking inconvenience of a flex brake that compensates for brake hydraulic pressure only for initial braking when a brake mode is forcibly switched, thus allowing a driver to recognize a change in braking force, and thereby improving stability when a vehicle is driven. The control system forcibly switches the brake mode, selected by a driver when a booster system fails, into a normal brake mode, and compensates to reduce the magnitude of brake hydraulic pressure, which is to be reduced when the brake mode is forcibly switched, during initial braking.

A driver assistance system for automated longitudinal guidance of a motor vehicle includes a sensor system configured to identify an upcoming traffic scene, including locating road users situated ahead of the motor vehicle; and a control unit. The control unit is configured to carry out an automated longitudinal guidance of the motor vehicle depending on the upcoming traffic scene such that, in response to detecting that the upcoming traffic scene is a following-travel standstill situation, the motor vehicle is braked to a standstill at a target stopping distance from a road user situated ahead and identified as a target object. The control unit is also configured to detect a manual request to reduce the predefined target stopping distance. The control unit is further configured to reduce the target stopping distance to a reduced target stopping distance on the basis of the request.
