Vehicle Data Recorder (VDR)

The VDR is the brain of the system. Waterproof, and installed permanently in your vehicle, it logs and time stamps information required by the system. Most of this information can be obtained over a simple connection to the vehicle's J1939 databus, but connections to sensors or switches on the seats and seatbelts provide some of the data. The vehicle data recorder records the following data once per second and stores it in a 48 hour loop:

• Vehicle Speed
• Acceleration
• Deceleration
• Engine Speed
• Engine Throttle Position
• ABS Event
• Seat Occupied Status
• Seat Belt Status
• Master Optical Warning Device Switch
• Time
• Date

Additionally, the VDR records the following data once per minute and has enough memory to store it for 100 engine hours:

• Maximum Vehicle Speed
• Maximum Acceleration
• Maximum Deceleration
• Maximum Engine Speed
• Maximum Engine Throttle Position
• ABS Event
• Seat Occupied with Seat Belt Unbuckled
• Master Optical Warning Device Switch
• Time
• Date

Stored data is password protected and can be downloaded from the VDR by a paired device (this can either be a nearby PC with an attached interface wireless module or a Data Collector) via wireless connection. VDR data retrieved in this manner can be viewed and analyzed with FRC's HAWK Software.
