DETERMINATION OF A CAPACITY OF A MOTOR VEHICLE HYDRAULIC PUMP, METHOD, COMPUTER PROGRAM PRODUCT AND DEVICE

摘要

A method for determining a lack of capacity of a motor vehicle hydraulic brake system pump actuated by an electric motor comprises the steps of producing a hydraulic pressure in a first brake circuit of the brake system by way of a plurality of pump elements of the pump, said elements being associated with the first pump circuit, limiting the produced hydraulic pressure to a test pressure and simultaneously detecting an engine-related parameter, and determining a lack of capacity of at least one of the pump elements based on a comparison of the parameter to a comparison value.
