Wheeled vehicle event data recorder forensic recovery and preservation system
First Claim
1. A wheeled vehicle event data recorder forensic recovery and preservation system, the system comprising:
- a forensic link adapter (20) configured for use with an electronic control module of a motor vehicle, the forensic link adapter (20) including;
one or more first microprocessors (23); and
a first software means (30) in communication with the first microprocessor (23);
at least one of the first software means (30) and the first microprocessor (23) configured to;
prevent a message being sent by an external network to the electronic control module from corrupting the integrity of at least one data measurement previously recorded by an electronic data recorder of the electronic control module; and
extract the previously recorded data measurement from the electronic data recorder.

Abstract
A system and method to preserve the integrity of data being extracted from an electronic data recorder (“EDR”) of an electronic control module (“ECM”) makes use of a forensic link adapter (20) and, optionally, a sensor simulator (10) (when the ECM is out of the vehicle). The forensic link adapter (20) has one or more first microprocessors (23) and associated first software which prevent any message being sent by an external network from corrupting the previously recorded data measurements. The data measurements are then extracted, verified, and stored in a separate file. The sensor simulator (10) has one or more second microprocessors (23), associated second software, and a bank of resistors (21) that mimic sensors normally in communication with the ECM. The simulator “tricks” the ECM into thinking it is still in the vehicle by using the replicating vehicle system values the ECM normally sees when in the vehicle.

8. A method of recovering and preserving forensic data from an electronic data recorder of an electronic control module, the method comprising the steps of:
-
(i) preventing a message being sent by an external network to the electronic control module from corrupting the integrity of at least one data measurement previously recorded by the electronic data recorder; (ii) extracting the previously recorded data measurement from the electronic data recorder; (iii) verifying the integrity of the extracted previously recorded data measurement; and (iv) storing the verified extracted previously recorded data measurement in a file independent of the electronic data recorder. - View Dependent Claims (9, 10, 11, 12, 13)
