Patent ID: 8540324

Claim:
A brake system comprising an actuating device and a control and regulating device, at least one electromotive drive device, and a valve, the control and regulating device being configured to control the at least one electromotive drive device using the movement and/or position of the actuating device, the drive device being configured to adjust a piston of a piston-cylinder system via a non-hydraulic gearing device to adjust pressure in the working chamber of the cylinder, the working chamber being connected to a wheel brake by a pressure line; wherein the valve is arranged between the brake cylinder of the wheel brake and the working chamber of the piston-cylinder system; wherein the control and regulating device is further configured to open the valve for both pressure reduction and pressure build-up in the brake cylinder and to close the valve to maintain the pressure in the brake cylinder; wherein the brake system is configured to adjust the pressure in one or more brake cylinders, by means of the piston-cylinder system and the valves associated with the wheel brakes, in which the piston of the piston-cylinder system is configured for adjusting the pressure in the one or more brake cylinders during both normal operation and during implementation of anti-lock braking and anti-slip regulation; and wherein the brake system is further configured to adjust the speed of change of the pressure build-up and/or pressure reduction in the wheel brakes by means of the piston-cylinder system as a function of the driving state or the brake regulation of the vehicle or the respective wheel to be decelerated, wherein control of one or more pressure gradients is performed based on an evaluation of at least one pressure-volume characteristic relationship of a respective brake, based on at least one of piston travel, wheel acceleration, current, or pressure.
