Method and device for vehicle control events data recording and securing
First Claim
1. A device for authenticating and securing control event data for a vehicle, comprising:
- A) a microcontroller, coupled to receive control event information, for attaching a first time stamp and vehicle identification number VIN to the control event information to provide first information and sending the first information to memory in time overlap fashion;
B) the memory, coupled to the microcontroller and a microprocessor, for storing first information and second information in time overlap fashion; and
C) the microprocessor, coupled to the memory and a plurality of transducers, for determining whether received impact data varies from previous impact data, and where received impact data varies, adding a second time stamp and VIN to the received impact data to form second information.

Abstract
A device (100) and method (200, 300) authenticate and secure control event data for a vehicle, wherein the device includes: A) a microcontroller (104), coupled to receive control event information, for attaching a first time stamp and vehicle identification number VIN to the control event information to provide first information and sending the first information to memory (106) in time overlap fashion; B) the memory (106), coupled to the microcontroller (104) and a microprocessor (108), for storing first information and second information in time overlap fashion; and C) the microprocessor (108), coupled to the memory (106) and a plurality of transducers (110), for determining whether received impact data varies from previous impact data, and where received impact data varies, adding a second time stamp and VIN to the received impact data to form second information.

4. A method for authenticating and securing control event data for a vehicle, comprising the steps of:
-
A) sending control event information and data to a microcontroller; B) attaching, by the microcontroller, a first time stamp and vehicle identification number to the control event information and data to provide first information and sending the first information to a memory; C) storing the first information in a list in the memory in time overlap fashion; D) determining whether one of;
an ignition of a vehicle is in off position and a predetermined time has elapsed, and where one of;
the ignition is on and the predetermined time is unelapsed, determining whether any other control event has occurred;E) where another control event has occurred, returning to step A; F) where another control event has failed to occur, ending; G) where one of;
the ignition is in an off position and the predetermined time has elapsed, sending instructions to the memory to start a new list in overlap fashion;H) determining whether another control event has occurred; I) where another control event has occurred, returning to step A; and J) where another control event has failed to occur, ending.

5. A method for authenticating impact data and control event information in a vehicle, comprising the steps of:
-
upon transducers being impacted, A) sending impact data to a microprocessor; B) determining whether impact data varies and where impact data fails to vary, ending, and where impact data varies, adding a time stamp two and a vehicle identification number to the impact data to form second information and storing the second information in memory; C) determining whether a manual lock is in use and; where the manual lock is in use, using the manual lock to retain the second information unchanged in memory; and where a manual lock fails to be in use, using an auto lock to retain the second information unchanged in memory; D) obtaining first information on control events and data and comparing with second information; E) determining whether the first information and the second information is synchronized; F) where the first information and the second information fails to be synchronized, reporting unauthenticated data/tampering; and G) where the first information and second information is synchronized, storing the first information and the second information in memory.

6. A method for interpreting control event data and impact data in a vehicle to provide an analysis of an accident, comprising the steps of:
-
A) determining whether access is authorized to stored impact data with time stamp two and control event information and data with time stamp one in the vehicle; B) where access is unauthorized, denying access; C) where access is authorized, obtaining impact data with time stamp two and control event information and data with time stamp one and interpreting the impact data with time stamp two and control event information and data with time stamp one to provide an analysis of the accident.
