Abstract

A method for operating a braking system of a vehicle includes: establishing a first setpoint brake pressure to be set in a first wheel brake cylinder of a first brake circuit and a second setpoint brake pressure to be set in a second wheel brake cylinder of a second brake circuit; reducing first and second actual brake pressures by setting a master brake cylinder pressure to be no greater than a minimum of the first and second setpoint brake pressures, and controlling a first switchover valve of the first brake circuit and/or of the second brake circuit; and/or increasing the first and second actual brake pressures by setting the master brake cylinder pressure to be no smaller than a maximum of the first and second setpoint brake pressures, and activating a first wheel inlet valve of the first brake circuit and/or of the second brake circuit.
