abstract="Measures to protect vulnerable road users during low-speed maneuvers are required. For example, systems that use cameras to display the vehicle's rearview are popular. However, some vehicles are difficult to equip with a rear view camera system. To  avoid a crash when driving in reverse, it is also effective to identify the presence  of pedestrians via an audible warning using a device (e.g., clearance sonar). It may  be cheaper to install than a rearview camera system. Installation cost is also  important for the spread of equipment that reduces a crash. It is necessary to  clarify the minimum specifications that balance cost and reduce crashes. Device  specifications (e.g., detection distance and response delay) may affect the crash  reduction rate. There should be a detection distance required for the sonar to have  the same crash reduction effect as the rear view camera system. Thus, in this study,  we conducted experiments and obtained data about how a vehicle moves and driver  reactions to audible warnings when driving in reverse. Based on the acquired data, a  numerical simulation was performed to determine whether a driver could avoid a crash  under various circumstances. As a result, it was shown that the clearance sonar must  have a detection distance of 0.8 m or more to expect the same effect as a rearview  camera system. In other words, to expect sonar to have the same performance as a  rearview camera, a detection distance of at least 0.8 m should be set as a  specification.<p /> <p>Language: en</p>",
