Method for localization of interlock errors in high-voltage on-board power supply of motor vehicle, involves retrieving error information by diagnosis unit that automatically displays sequence of measurements provided for error localization

摘要

The method involves connecting high-voltage components (K1-KN) with high-voltage sources of a high-voltage on-board power supply (HV). Each of the components is connected with an interlock circuit (30) by a signal detector (100) so that a section of the interlock circuit runs between the components and has an error memory for storing error information. An output signal is generated for monitoring the interlock circuit for interlock error. The error information is retrieved by a diagnosis unit (300) that automatically displays a sequence of measurements provided for error localization. An independent claim is also included for an arrangement for error localization in a high-voltage on-board power supply of a vehicle.
