The Difference between Collision Warning Systems and Partial Autonomous Driving Assistance Systems in US
TapTechNews July 16th news, with the rapid development of automotive technology, it is easy for people to get confused about the uses and purposes of different functions. A recent study by the Insurance Institute for Highway Safety (IIHS) in the US emphasizes the importance of understanding these technological differences. The study shows that there is a significant difference in safety effects between collision warning systems and some partial autonomous driving assistance systems.
Collision warning technology includes functions such as automatic emergency braking, lane departure warning, and blind spot monitoring, while partial autonomous driving assistance systems include functions such as adaptive cruise control and lane keeping assistance. The research data shows that the former can effectively reduce collision accidents, while the latter's effect seems not so obvious.
The study was conducted by the IIHS and specifically compared and analyzed older BMW and Nissan models from 5 to 11 years ago with and without the above technologies. David Harkey, chairman of the IIHS, said: This study result shows that some partial autonomous driving assistance systems are more like comfort features such as power windows or heated seats rather than safety technologies. The research data also confirms this.
It was found that the property damage liability claim rate of Nissan cars equipped with automatic emergency braking systems decreased by 8%, while the claim rate of Nissan models equipped with partial autonomous driving assistance systems did not decrease further. The collision claim rate of BMW cars equipped with automatic emergency braking and forward collision warning systems decreased by 7%, and the property damage liability claim rate decreased by 13%. Interestingly, the property damage liability claim rate of BMW cars equipped with adaptive cruise control decreased by 25%.
However, TapTechNews noticed that there are also some notable limitations in this study. Firstly, systems such as automatic emergency braking and forward collision warning are usually turned on by default, while most partial autonomous driving assistance systems are not. Therefore, the study cannot determine the number of accidents that occur when these systems are activated and the number of accidents that occur when the systems are off. The study also points out that other factors, such as headlights, also play an important role in accident prevention.
Moreover, as technology develops, most automotive safety assistance systems are constantly improving. Therefore, in the next few years, the performance of cars equipped with the same technology may change significantly. Functions such as lane keeping assistance may help drivers avoid accidents, but more data is needed to determine which semi-autonomous driving systems are the most effective.
