A control apparatus for an electromechanical-brake-booster of a vehicle, having: an electronic-device to control an electric-motor of the electromechanical-brake-booster so that an output piston, connected indirectly to the electric-motor, of the electromechanical-brake-booster is displaceable out of its initial-position by the controlled electric-motor, such that only after a displacement of the output-piston out of its initial-position by at least a predefined limit displacement travel does a frictional engagement exist between the output-piston and an input-piston that is indirectly connected to the brake-pedal and is displaced by the actuation of the brake-pedal, and such that a speed of the output-piston displaced out of its initial-position by less than the limit displacement travel is at first increased from a reference-speed to a maximum-speed and is then reduced from the maximum-speed to the reference-speed. The invention furthermore relates to a method for operating an electromechanical-brake-booster of a vehicle.

Control device and method for operating an electromechanical brake booster of a vehicle

A control device for a vehicle brake system, having a control device/arrangement by which a closing signal is outputtable to an isolation valve via which a first brake circuit is hydraulically connected to a main brake cylinder, and at least one first control signal is outputtable to at least one first hydraulic component, so that a first actual brake pressure in the first brake circuit can be varied, an existing functional impairment of the at least one first hydraulic component and/or of at least one further brake system component being determinable, or a warning signal being receivable, and, if warranted, a closing signal being outputtable to a changeover valve of a second brake circuit, and, after or simultaneously with an outputting of the closing signal to the changeover valve, an opening signal being outputtable to the isolation valve. Also described is a related method for operating the vehicle brake system.

Control device for a brake system of a vehicle, and method for operating a brake system of a vehicle

A method for operating an electromechanical brake booster of a braking system including: establishing a virtual setpoint brake pressure variable; and establishing a setpoint differential travel variable with respect to a setpoint differential travel at least by: establishing a first intermediate value while taking into consideration a first weighting relation and a minimum from a first value set including the virtual setpoint brake pressure variable and a jump-in pressure variable; and establishing a second intermediate value while taking into consideration a second weighting relation and a maximum from a second value set including zero and a value of a difference using the virtual setpoint brake pressure variable as the minuend and the jump-in pressure variable as the subtrahend. A method for operating a recuperative braking system is also provided.
