#CMT# #/CMT# The sensor arrangement (4) has sensors for electric state variables of current, voltage and temperature in the area of the battery (1). The sensor arrangement has a storage unit for storing the processes of the values of current, voltage and temperature during an engine start of the motor vehicle, and a filter unit for comparison of the measured values with stored values or with time or temperature-dependent processes of the values. #CMT#USE : #/CMT# Sensor arrangement for state detection of a battery and load in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The sensor arrangement has a storage unit for storing the processes of the values of current, voltage and temperature during an engine start of the motor vehicle, and a filter unit for comparison of the measured values with stored values or with time or temperature-dependent processes of the values, and hence ensures accurate detection of the electric state variables, and prevents breakdown of the vehicle by identifying creeping defects of the starter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of an arrangement of a sensor arrangement within the area of the battery of a motor vehicle. 1 : Battery 4 : Sensor arrangement 9 : Evaluation unit 10 : Generator 11 : Starter #CMT#INDUSTRIAL STANDARDS : #/CMT# The diagnostic connection with the central evaluation unit takes place over a Local interconnect network bus. |
