Description

Connectivity-based vehicle infotainment integration test bed The present invention relates to a connectivity-based vehicle infotainment integrated test bed, and in particular to an integrated test bed for verifying unit functions and interlocking service functions in a connectivity-based vehicle infotainment system. A vehicle infotainment system refers to a system that integrates various information provision and entertainment functions to enhance the driving and passenger experience within a vehicle. With recent advancements in IT technology, connectivity—the ability of vehicles to connect with external networks (e.g., the Internet, cloud, other vehicles, infrastructure, etc.)—is expanding; accordingly, infotainment systems are providing enhanced features to drivers and passengers based on this connectivity. For example, infotainment systems are now connected to the cloud, enabling them to provide real-time information such as weather, traffic conditions, and news, as well as streaming services like music and video. Furthermore, vehicle status information is transmitted to the cloud, allowing the infotainment system to update the vehicle's status in real time, and software updates are becoming possible via OTA (Over-the-Air). Meanwhile, as connectivity-based infotainment technology develops rapidly, the data throughput and functional complexity of vehicles are increasing dramatically, making functional evaluation of infotainment essential to ensure user experience, system safety and performance, and the protection of personal privacy. FIG. 1 shows a configuration diagram of a connectivity-based vehicle infotainment integrated test bed according to an embodiment of the present invention. In order to provide a detailed explanation sufficient for a person skilled in the art to easily implement the technical concept of the present invention, the most preferred embodiment of the present invention will be described with reference to the accompanying drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the present invention, such detailed description is omitted. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached to this specification. FIG. 1 is a configuration diagram of a connectivity-based vehicle infotainment integrated test bed according to an embodiment of the present invention. Referring to FIG. 1, the vehicle infotainment integrated test bed (10) may be configured to include a Driver Infotainment System (DIS) board (20), a Passenger Infotainment System (PIS) board (30), a cloud server (40), a vehicle simulator (50), a test PC (60), and an integrated gateway (70). The DIS board (20) can provide the vehicle driver with navigation, instrument panel, vehicle status monitoring, etc., necessary for safe driving, and can deliver real-time information needed while driving. The DIS board (20) can control and manage driving information (e.g., speed, navigation, vehicle status information, etc.) and various controllers that the driver can operate (e.g., voice recognition, navigation, audio settings). Specifically, the DIS board (20) prioritizes safety and convenience while driving and can provide vehicle status and warning messages by linking with information that helps with driving, such as vehicle driving information, status/diagnostic information, navigation, or an Advanced Driver Assistance System (ADAS). In addition, it can provide voice/motion control and hands-free calling and messaging functions for driving convenience, and provides a UI for media control such as music or radio. The PIS board (30) can provide entertainment and convenience features to passengers in the rear seat or passenger seat of the vehicle while driving by supporting access to content such as music, movies, internet search, and social media. The PIS board (30) may include a GPU required for HD video processing, a network connection, an HDMI or DisplayPort, etc. The PIS board (30) can create a media environment independent of the driver to provide enjoyment and comfort to the occupant while driving. For example, the PIS (22) can provide various multimedia streaming content such as Netflix, YouTube, and games, and can perform various online activities such as web surfing and checking emails via an internet connection. In addition, it can provide entertainment through movies, music, apps, and games via a dedicated display, and can provide an audio environment independent of the driver's seat via headphones or a speaker system. The cloud server (40) is connected to a connected vehicle and exchanges various information in real time, thereby provi
