Performance of the Ford Pre-Collision Assist with Automatic Emergency Braking System in Instrumented Tests

2021-04-06
2021-01-0894
Modern Ford vehicles can be manufactured with a system known as Pre-Collision Assist with Automatic Emergency Braking (AEB). The Pre-Collision Assist feature uses camera technology to detect a potential collision with a vehicle or pedestrian directly ahead. If a potential collision is detected, an alert sound is emitted, and a warning message displays in the vehicle’s message center. If the driver response is not sufficient, AEB will be pre-charged and brake-assist sensitivity will be increased to provide full responsiveness if the driver does brake. If there is no perceived corrective action and a collision is imminent, the vehicle’s brakes can apply automatically. By detecting the possible collision and actuating the braking system, it is possible to prevent some collisions and lessen the severity of others. Testing of this system was conducted using a 2020 Ford Explorer. During several tests, the instrumented Ford was driven at a simulated target vehicle or pedestrian dummy.

Analysis of Vehicle GPS and Derived Speed Data from BMW NBT Evo Systems Acquired with Berla iVe

Many late-model BMW vehicles are equipped with an NBT Evo infotainment system. This system is seen in BMW vehicles in all global markets. Like infotainment systems from other manufacturers, this system records data elements that can prove to be key evidence to investigators of vehicular incidents. This system records timestamped tracklogs that consist of GPS coordinates paired with date/time data. These tracklog points, however, are not recorded in regular intervals. Testing of an instrumented BMW 430i was conducted in and around the Bruntingthorpe Proving Grounds in the United Kingdom. The test vehicle was instrumented with a Racelogic Video VBOX Pro. Data from the instrumentation was compared to the data acquired from the BMW by the iVe Ecosystem from Berla Corporation. The accuracy of the GPS coordinates recorded in the BMW tracklogs was determined by computing the distance between the recorded BMW data and the reference instrumentation data.

Analysis of Vehicle GPS and Derived Speed Data from Ford SYNC Generation 3, Version 2 Systems Acquired with Berla iVe

Data acquired from vehicle infotainment systems has continued its growth as key evidence in vehicle-related investigations. The accident reconstruction community continues to actively pursue digital data from vehicles to be used alongside traditional forms of physical and electronic evidence. Some of the vehicle infotainment systems that have provided valuable evidence for several years are now being updated by their manufacturers. One such system is the Ford SYNC Generation 3 (SG3) system. In 2019, Ford began installing an updated version of this system that included changes to the SYNC module. The new system, referred to as SYNC Generation 3, version 2 (SG3v2) is outwardly identical to the original SG3 system until the module is physically removed from the vehicle. Ford has released the new module globally and it has been observed in North America, Australia, the United Kingdom, and several European countries.

Analysis of Crash Data from a 2012 Hyundai Genesis Coupe Event Data Recorder

2012 Hyundai Genesis Coupes were manufactured with Airbag Control Modules (ACMs) with Event Data Recorder (EDR) functionality to record crash-related data. However, 2013 is the first model year supported by the download tool and software manufactured for Hyundai vehicles and distributed by Global Information Technologies (GIT) America, Inc. Prior published research has shown that EDR data can be collected from pre-2013 Hyundai vehicles using the GIT tool and some data elements from 2012 and earlier model year Hyundai vehicles are accurately translated - most notably, vehicle speed. To specifically examine the EDR data recorded by a 2012 Hyundai Genesis Coupe, two instrumented crash tests were conducted. Both tests involved broadside impacts into a second stationary vehicle and resulted in a non-deployment EDR recording. The Hyundai was human driven during both crash tests.

Analysis of Berla iVe Acquisitions of Vehicle Speed Data from Ford Sync Systems

Many modern automobiles’ infotainment/navigation systems store vehicle telematics and user-supplied infotainment data. This data is useful in a wide variety of analyses but is not available through traditional OEM tools. The necessity to access the infotainment module data for forensic analysis can be satisfied by utilizing the Berla iVe system. Similar to CDR/EDR technology, Berla iVe is a hardware and software tool that is used to acquire and analyze stored automotive data. However, CDR/EDR systems are generally developed in partnership with manufacturers or OEM suppliers. Berla iVe is a privately developed forensic system analogous to traditional forensic tools used to interrogate computer hard drives and smartphones. The technology is privately developed and tested. The data is then parsed using recognized forensics practices.

Analysis of Crash Data from a 2012 Kia Soul Event Data Recorder

The 2012 Kia Soul was manufactured with an Airbag Control Module (ACM) with an Event Data Recorder (EDR) function to record crash related data. However, 2013 is the first model year supported by the download tool and software manufactured for Kia vehicles and distributed by GIT America, Inc. Even with the same make and model, using the Kia EDR tool to image data from an unsupported model year calls into question whether some or any of the data has been properly translated. By way of example, a method for evaluating the usability of the crash related data obtained via coverage spoofing a 2012 Kia Soul is presented. Eight vehicle-to-barrier crash tests were conducted in a 2012 Kia Soul. The Kia EDR tool was utilized to retrieve crash data from the vehicle's EDR following each test by choosing the software translation settings for a 2013 Kia Soul. The recorded and translated crash data for those tests were analyzed and compared to on-board instrumentation.

Accuracy of Pre-Crash Speed Recorded in 2009 Mitsubishi Lancer Event Data Recorders

The accuracy of pre-crash data recorded in an Airbag Control Module (ACM) with Event Data Recorder (EDR) functionality has been studied and quantified for vehicles from several vehicle manufacturers. Most published research has involved vehicles with accessible data that can be downloaded via commercially available crash data retrieval equipment. Some Mitsubishi vehicles, including the 2009 Mitsubishi Lancer GTS, are capable of recording crash data that can be accessed only by the manufacturer. The accuracy of such data becomes important when it is intended to be used as part of a collision analysis. The pre-crash speed data recorded by a 2009 Mitsubishi Lancer vehicle was evaluated by generating artificial deployment events while running the vehicle on a 4-wheel dynamometer and simultaneously capturing data through the OBDII port. The tests were run at speeds up to approximately 145 kilometers per hour (90 miles per hour).
