Embodiment Construction

[0048] For ease of understanding, there are methods involved in the following figure 1 In the description of the is reserved for figure 2 and the reference numerals used for 3 for reference. figure 1 A flowchart illustrating an embodiment of a method for testing a cable set 150, 250 having several lines 157, 158, 159, 160, wherein at least one of the lines 157, 158, 159, 160 has a number of electrical components 161, 162.

[0049] In a first step S1 "Apply", the lines 157 , 158 , 159 , 160 are applied with an alternating voltage signal 102 , 202 . In a second measurement step S2 "Measurement", the current and the voltage of each line 157 , 158 , 159 , 160 to which the alternating voltage signal 102 , 202 is applied are measured. In a third step S3 "Comparison", the voltage-current characteristic curves of the corresponding lines 157, 158, 159, 160 created based on the respectively measured currents and the respectively measured voltages are compared with the voltage-curren...

Abstract

The present invention relates to a method for testing a cable set (150, 250) having a number of networks (157, 158, 159, 160), at least one of the networks (157, 158, 159, 160) having a number of electrical assemblies (161, 162), comprising the steps of: - applying (S1) an alternating voltage signal (102, 202) to the networks (157, 158, 159, 160); - measuring (S2) the current and the voltage for each of the networks (157, 158, 159, 160) to which the alternating voltage signal (102, 202) is applied; comparing (S3) voltage-current characteristic curves of the relevant networks (157, 158, 159, 160) that have been created on the basis of the relevant measured current and the relevant measured voltage with a specified target voltage-current characteristic curve (106, 206) for the relevant network (157, 158, 159, 160); and outputting (S4) an error message (107, 207) if one of the voltage-current characteristic curves created on the basis of the relevant measured current and the relevant measured voltage deviates from the corresponding target voltage-current characteristic curve (106, 206) by more than a specified threshold value. The present invention also relates to a corresponding testing device (100, 200).

Description

technical field [0001] The invention relates to a method for testing a cable set. Furthermore, the invention relates to a corresponding testing device. Background technique [0002] The present invention is mainly described below in connection with the on-board electrical system of the vehicle. It goes without saying that the invention can also be used with other electrical circuits. [0003] A number of electrical and electronic components are installed in modern vehicles, such components may be, for example, controls that provide convenience functions or driver assistance functions. Several such controls are already built into modern vehicles. Usually, the control devices are electrically connected to each other by means of cable bundles or sets of cables. Thus, such cable bundles or sets of cables can have different electrical lines. [0004] To increase efficiency in vehicle assembly, electrical components will in the future be placed in cable bundles or cable group...
