US 11,077,836 B2 · Method for controlling a hydraulic braking system

Abstract

In a method for controlling a hydraulic braking system, wherein the braking system includes a hydraulic pump that is driven by an electric motor so as to generate a volume of fluid flow for the hydraulic braking system. the electric motor is controlled in such a manner that fluid pulsation in the hydraulic braking system is counteracted by means of modulating a rotational speed of the electric motor. The modulation is generated by means of the control procedure. Furthermore, a device is designed and configured so as to perform the method.

A method for controlling a hydraulic braking system comprising:

controlling an electric motor, which drives a hydraulic pump so as to generate a volume of flow in the hydraulic braking system, in such a manner that fluid pulsation in the hydraulic braking system is counteracted by modulating a rotational speed of the electric motor in a sinusoidal manner, said modulation being generated by a control procedure.

Dependencies are inferred from the claim text.
