Title
(EN) Systems And Methods To Diagnose Vehicles Based On The Voltage Of Automotive Batteries
Abstract
(EN)

Systems and methods for battery-based vehicle diagnostics are provided. Various embodiments include a battery-based diagnostics system that guards vehicles against anomalies with a cyber-physical approach. The diagnostics system can be implemented as an add-on module of commodity vehicles attached to automotive batteries, thus providing vehicles an additional layer of protection. The automotive battery can operate in strong dependency with many physical components of the vehicle, which is observable as correlations between battery voltage and the vehicle's corresponding operational parameters, e.g., a faster revolutions-per-minute (RPM) of the engine, in general, leads to a higher battery voltage. These embodiments exploit such physically induced correlations to diagnose vehicles by cross-validating the vehicle information with battery voltage and may be based on a set of data-driven norm models constructed online.
