System and method for on-vehicle dynamic accident recreation using accident data recording
First Claim
1. A method for recreating a prior operation of a crashed vehicle before or at the time of an accident, comprising:
- retrieving, from a memory of an accident data recorder, a prior vehicle operation data corresponding to the prior operation of the crashed vehicle before or at the time of the accident, the prior vehicle operation data including at least one of a prior steering input data or a prior braking input data;
analyzing, using a processor connected to the accident data recorder, the prior vehicle operation data;
providing at least one electronic controller configured to control a test operation of a test vehicle that is similar in make and model to the crashed vehicle;
outputting, using the processor, a vehicle control data or signal to the at least one electronic controller based on the analyzed prior vehicle operation data; and
automatically operating, using the at least one electronic controller, the test vehicle based on the vehicle control data or signal in order to recreate the prior operation of the crashed vehicle in response to the at least one of the prior steering input data or the prior braking input data.

Abstract
A system and a method for recreating an operation of a crashed vehicle during and/or before the accident. An accident data recorder collects vehicle operation data related to the operation of the crashed vehicle prior to and/or during the accident. A processor may analyze the prior vehicle operation data that may include prior acceleration input data, prior braking input data, and/or prior steering input data and may output vehicle control data to at least one electronic controller based on the prior vehicle operation data. The at least one electronic controller automatically operates the test vehicle on a test surface to recreate an operation of the crashed vehicle during and/or before the accident. At least one electronic controller unit automatically and accurately recreates a response of the crashed vehicle to the prior acceleration input, the prior steering input, and the prior braking input.

-
retrieving, from a memory of an accident data recorder, a prior vehicle operation data corresponding to the prior operation of the crashed vehicle before or at the time of the accident, the prior vehicle operation data including; a prior acceleration input data detected by an acceleration input sensor before or at the time of the accident, a prior steering input data detected by a steering input sensor before or at the time of the accident, and a prior braking input data detected by a braking input sensor before or at the time of the accident; analyzing, using a processor connected to the accident data recorder, the prior steering input data, the prior braking input data, and the prior acceleration input data; providing at least one electronic controller configured to control a test operation of a test vehicle that is similar in make and model to the crashed vehicle; outputting, using the processor, a vehicle control data or signal to the at least one electronic controller based on the analyzed prior vehicle operation data, the vehicle control data or signal including; an acceleration control data or signal being based on the prior acceleration input data, a steering control data or signal being based on the prior steering input data, and a braking control data or signal being based on the prior braking input data; and automatically operating, using the at least one electronic controller, the test vehicle based on the vehicle control data or signal in order to recreate the prior operation of the crashed vehicle or a response of the crashed vehicle to the prior acceleration input data, the prior steering input data, and the prior braking input data. - View Dependent Claims (15, 16)
