METHOD FOR MONITORING A PUMP

摘要

A method for monitoring the functioning of an electric motor-driven pump (1), preferably in a vehicle (F), which has an internal electronics system (4) by means of which functional parameters of the pump (1) are monitored. The internal electronic system (4) relays the values of the functional parameters to a central control device (8) via an internal communication interface (6), and the values of the functional parameters are detected and monitored in the central control device (8) with respect to critical limiting values. The change over time of at least one value of the functional parameters is detected in the central control device (8), and a malfunction of the pump (1) is deduced if a value of at least one functional parameter remains constant over a predefined period of time.

1. A method for monitoring the functioning of an electric motor-driven pump (1) which has an internal electronics system (4) by means of which functional parameters of the pump (1) are monitored, comprising:
using the internal electronic system (4) to relay the values of the functional parameters to a central control device (8) via an internal communication interface (6), detecting and monitoring the values of the functional parameters in the central control device (8) with respect to critical limiting values, detecting the change over time of at least one value of the functional parameters in the central control device (8), and deducing a malfunction of the pump (1) if a value of at least one functional parameter remains constant over a predefined period of time.
