"Understanding How Brakes Work Properly to Prevent Sudden Acceleration Suspicion Accidents"

"Accurately understanding the operating principles of braking systems and eliminating misunderstandings and prejudices about event data recorders and traffic accident investigation procedures are essential to prevent suspected sudden unintended acceleration incidents."

On the 12th, Kang Nam-hoon, chairman of the Korea Automobile Mobility Industry Association (KAMA), said this at the 'Automobile Sudden Unintended Acceleration Suspected Accident Briefing' jointly hosted by KAMA and the Korea Automobile Importers & Distributors Association (KAIDA). Chairman Kang emphasized the importance of correct awareness improvement activities, stating, "The vague anxiety of the public regarding suspected sudden unintended acceleration incidents is increasing."

The automotive industry is increasing the application of new technologies such as pedal misoperation prevention devices and emergency automatic braking systems to alleviate concerns about suspected sudden unintended acceleration incidents. Recently, pedal misoperation prevention devices have been increasingly applied starting from small electric vehicles like the Casper, and emergency braking systems are being gradually expanded to detect not only vehicles but also pedestrians, bicycles, and other targets.

First, at the briefing, Professor Choi Young-seok of Wonju Halla University, who presented on the event data recorder (EDR) section, said, "EDRs are a key tool for analyzing traffic accidents, and their reliability has been verified through the analysis of tens of thousands of accidents both overseas and domestically." He also introduced the current status of revising standards, including adding stored data items to enhance recent EDR analysis capabilities.

In the second topic on brake systems, Professor Lee Ho-geun of Daeduk University explained the scope and magnitude of brake functions. He said, "The braking force of a vehicle is designed to be greater than the energy generated by the vehicle's weight and speed," and added, "Through the brake override function, when braking and acceleration signals are sent simultaneously, the braking signal takes precedence, so when the brake is applied, the vehicle's speed will always decrease and come to a stop."

Next, in the analysis procedure of suspected sudden unintended acceleration incidents, Professor Park Sang-ji of Daejeon Health Institute of Technology took the stage. Professor Park stated, "Suspected sudden unintended acceleration incidents can occur in various forms such as accelerator cable sticking, floor mat interference, and engine oil intake into the intake system," and emphasized, "Sudden unintended acceleration can happen to anyone regardless of driving experience, and it is urgent to acknowledge that most cases are human errors (driver faults) and establish countermeasures."

Research Officer Cho Min-je from the National Police Agency, who is in charge of accident analysis, explained, "Since 2017, we have introduced a work process called traffic accident engineering analysis, conducting EDR-centered analysis, vehicle collision simulation analysis, video analysis, and polygraph analysis to uncover the actual causes." He added, "In cases of social issues or major incidents, the cases are transferred to the National Forensic Service and the Road Traffic Authority for more precise analysis."
