Method for avoiding excess pressures in a pressure medium circuit of an electronically slip-controllable braking system in the event of a decline of an intrinsic elasticity of the braking system and electronically slip-controllable braking system

A method for avoiding excess pressures in a pressure medium circuit of an electronically slip-controllable braking system in the event of a decline of an intrinsic elasticity of the braking system, the pressure medium circuit being equipped with a pressure generator which applies a circuit pressure to the pressure medium circuit, an activatable drive of the pressure generator, and an electronic control unit, by which a setpoint value for a delivery volume of the pressure generator is ascertained during a braking procedure by a comparison of a setpoint value to an actual value for the circuit pressure in the pressure medium circuit and converted into an activation signal for the drive of the pressure generator, the method comprising:

• establishing, depending on existing elasticity or the elasticity to be expected of the braking system, a maximum pressure gradient with which the pressure in the pressure medium circuit changes, the maximum pressure gradient being based on an ascertainment of an activation signal for the drive of the pressure generator by the electronic control unit, wherein a limiting value for the delivery volume of the pressure generator is determined from the elasticity of the pressure medium circuit and the established pressure gradient, the delivery volume corresponding to the limiting value being less than the delivery volume corresponding to the setpoint value.
