In 2007, DELTA |v| became Mack Trucks’ Designated Affiliate for the East Coast. Visit hvedr.com for more information on our designation.
HVEDRs may also be referred to as the truck’s black box.
In recent years, HVEDR downloads have become common in the trucking industry. The term Event Data Recorder (EDR) is used to describe any type of vehicle module which has the capability of storing data surrounding a defined event. The event may be a collision event, a sudden change in vehicle speed, a controlled or uncontrolled stop, or a fault detected in a monitored sensor.
In heavy vehicles, the Engine Control Module (ECM) controls and monitors engine function. The ECM may also contain the ability to record event data. Electronic Control Units (ECU) is the generic name for other devices that may be connected to the vehicle network. ECUs may also have the ability to record event data. The available data and its sources will depend on the truck’s model year and engine manufacturer.
DELTA |v| is the only firm on the East Coast that can download any EDR-equipped heavy vehicle. Our engineers customize an extraction process to fit each client’s needs. Three common extraction methods are:
- Onsite Downloads: An engineer plugs directly into the incident vehicle to extract HVEDR data.
- Surrogate Truck: The EDR is removed from the incident vehicle and stored until the download is performed. During the time of data retrieval, the module is placed on a surrogate truck for power during the extraction.
- Benchtop Downloads: The EDR is removed from the incident vehicle, although no vehicle is required during this extraction. The HVEDR plugs directly into an equipped laptop for the data download.
The DELTA |v| HVEDR team possesses specialized training, knowledge, and experience to extract and secure collision-related data. Incident-related data that may be retrieved includes speed, throttle percentage, brake status, and last stop information.
