Method, monitoring device and starter for monitoring a starter of an internal combustion engine

Abstract

The invention relates to a method for monitoring a starter (12) of an internal combustion engine (19), the method comprising: detecting at least An electrical parameter (U30, U45, U50, I30); analyze the detected electrical parameter and obtain at least one characteristic value; compare the obtained at least one characteristic value with a predetermined reference value; if the at least one characteristic value differs from said reference value by at least a predetermined threshold value, a fault in the mechanical coupling of said starter (12) to said internal combustion engine (19) is recognized; if a connection between said starter (12) and said Failure of the mechanical coupling of the internal combustion engine (19), the starter (12) is switched off. The invention also relates to a monitoring device and a starter (12).

Description

technical field [0001] The invention relates to a method for monitoring a starter of an internal combustion engine, in particular a commercial vehicle, a monitoring device for carrying out the method, and a starter with such a monitoring device. The invention thus relates in particular to the technical field of motor vehicles, in particular commercial vehicles, and in particular to the field of starters for internal combustion engines for commercial vehicles. Background technique [0002] Since the internal combustion engine generally cannot be started by itself, ie without assistance, the motor vehicle has an electric starter (starter) which is used to move the internal combustion engine in order to start it. In contrast to most passenger cars, commercial vehicles such as trucks generally do not have battery monitoring, for example by means of so-called battery sensors, which can provide information about the state of the battery in the commercial vehicle. Therefore in com...

AI Technical Summary

Problems solved by technology

An insufficient or only insufficient mechanical coupling of the starter to the internal combustion engine can lead not only to an interruption of the starting process without success, but also to damage to the ring gear and / or Damage to the starter, which would require cumbersome and / or costly repairs to the internal combustion engine and / or the starter

In particular, it is therefore necessary to replace the ring gear of the internal combustion engine or the corresponding mechanical components of the starter that are damaged by such an insufficient and / or unsuccessful starting process, which requires, in addition to huge material costs, also a large Material consumption

[0004] In addition, a damaged starter and / or a disturbed mechanical coupling means that the vehicle cannot be restarted without first repairing and / or replacing the starter and / or the combustion engine

Consequently, such damage and / or destruction can render the vehicle no longer driveable and / or parkable, thereby incurring substantial costs of vehicle towing and / or failure, in addition to the cost of replacing the starter and / or repairing the internal combustion engine
