System for anlyzing vehicle and driver behavior
First Claim
1. A system for analyzing vehicle and driver behavior, comprising:
- a data preprocessing means that converts operation information of an in-vehicle electrical system, data available via an in-vehicle data network, and additional information available from an electrical device constituting a vehicle into a format capable of calculation therein;
a vehicle model and estimation means that estimates non-measurable variables in an in-vehicle sensor based on the preprocessed data from the data preprocessing means;
a model-based reconstruction means that reconstructs an accident scenario by unifying the preprocessed data from the data preprocessing means and the estimated variables from the vehicle model and estimation means to a common time stamp; and
an assessment means that assesses vehicle and driver behavior based on the accident scenario reconstructed by the model-based reconstruction means.

Abstract
A system for analyzing vehicle and driver behavior includes: a data preprocessing unit that converts operation information of an in-vehicle electrical system, data available via an in-vehicle data network, and additional information available from an electrical device constituting a vehicle into a format capable of calculation therein; a vehicle model and estimation unit that estimates variables which can not be measured by means of in-vehicle sensors based on the preprocessed data; a model-based reconstruction unit that reconstructs an accident scenario by unifying the preprocessed data and the estimated variables from the vehicle model and estimation unit to a common time stamp; and an assessment unit that assesses vehicle and driver behavior based on the accident scenario reconstructed by the model-based reconstruction unit.
