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

A hydraulic brake system for a vehicle, comprising:

• a control device for a hydraulic brake system of a vehicle, including:
• an electronic device, wherein, as a reaction to a supplied warning signal of an automatic speed control device of the vehicle and/or of a sensor system of the vehicle as to a probable, early request for braking of the moving vehicle by the automatic speed control device or by a driver of the vehicle, is configured to force at least one wheel exhaust valve of the hydraulic brake system, undelayed or delayed, into an open position and to activate a motor of a motorized hydraulic device of the hydraulic brake system so that brake fluid is conveyable to the at least one wheel exhaust valve and/or to at least one associated wheel brake cylinder by operation of the activated motor,
• wherein the electronic device is configured, as a reaction to a supplied brake setpoint signal of the automatic speed control device and/or of the sensor system, as to requested braking of the moving vehicle, with a current setpoint deceleration not equal to zero, to force the at least one wheel exhaust valve into a closed position and to control the motor of the motorized hydraulic device according to the setpoint deceleration currently requested;
• the motorized hydraulic device;
• the at least one wheel brake cylinder;
• and
• the at least one wheel exhaust valve.
