Description

eHMI Device for Motion Information Display of a Moving Object The present invention relates to an eHMI device for displaying movement information of a moving body, and more specifically, to an eHMI device for displaying movement information of a moving body that can intuitively display the movement status of a moving body to the outside by displaying movement information, such as acceleration and deceleration of a vehicle, without access to CAN communication. As autonomous driving technology advances, situations are arising where drivers cannot directly communicate with pedestrians or surrounding road users. Previously, communication was achieved through gestures or eye contact, but in autonomous vehicles, the system must take over this role. Consequently, there is an increasing need for eHMI (external Human-Machine Interface) systems that can convey the vehicle's driving status or intentions to the surroundings. eHMI systems currently under development for application in autonomous vehicles and mobility are configured such that the vehicle system recognizes the surrounding environment and, accordingly, displays information such as the vehicle's driving status or intentions externally. The information displayed externally is message information that advises or directs specific actions to pedestrians or other road users based on the vehicle's recognition of them, and for this purpose, a CAN (Controller Area Network) communication environment capable of accessing internal vehicle data is required. However, these advisory and instructional eHMIs are not only difficult for automakers to apply to mass-produced vehicles due to legal and ethical reasons, but also have limitations in that they can confuse pedestrians. Furthermore, conventional eHMI systems have a complex structure requiring the integration of various sensors—such as radar, cameras, lidar, and ultrasonic sensors—to perceive the surrounding environment; consequently, they face limitations in high development and mass production costs and are difficult to install retrofit on existing vehicles. Therefore, research is needed on a technology that can easily display the status of a moving object currently in motion to the outside without CAN communication access.
