webOS Auto 2.5


webOS Auto 2.5 is the third official release of webOS Auto that includes improving the details of automotive functionality as well as a series of management services to further increase the competitiveness of its car features. webOS Auto focuses on delivering enhanced in-car experience with multi-display support for in-vehicle infotainment (IVI) systems that offer consistent and seamless UI/UX. webOS Auto has incorporated aggregated services provisioning that helps carmakers care free from the bane of bringing all necessary services and content together.

webOS Auto also supports co-existence model with carmakers’ own systems on a single ECU. This consolidation is accomplished by a single SoC with a virtualization layer that can power the carmaker’s existing system such as cluster HMI as well as webOS Auto for IVI system.

Architecture at a Glance

The platform architecture is mainly divided into two partitions: webOS Auto and vendor specific parts. In addition to the defined boundary of webOS Auto components, the platform can be extended with vendor specific features that reflect automotive manufacturers’ own design and implementation.

webOS Auto part is a set of platform services and framework extensions developed in addition to the webOS reference platform in order to support the automotive needs. Most components under this partition are provided as built-in, and some specific components can be customized to the vendor needs.

Vendor specific part specifies the software components that are highly specific to each automotive manufacturer and depend on the platform design and implementation. By using the guidance provided by webOS Auto including reference UI/UX and guidelines, automotive manufacturers can easily create their own services and integrate them with their existing platform. Furthermore, the webOS platform’s flexible and pluggable architecture allows 3rd party services and applications to be easily deployed.


Multi-user Management

webOS Auto focuses on providing features for managing multi-user environment. The Account Manager service, which replaces User Profile Manager and Session Manager services, has been included to provide more personalized management and deal with the persistence of user accounts. The persistence of an account means that each screen is associated with a dedicated user account, making the user’s customized and personalized settings available to the user when accessed on any device. For the sake of protecting user profile and data security under multi-user context, Pluggable Authentication Module (PAM) based multi-user authentication functionality and the Login app which facilitates uer profile management have been added.

Improved Car Services

A new mode for Instrument Cluster has been included. A vehicle’s instrument cluster generally is a combination of display components such as speedometer, odometer, and fuel gauge that is installed in front of the driver’s handle. webOS Auto is now capable of integrating Instrument Cluster with its existing user experiences in IVI systems. For the audio stream management, the audio focusing functionality has been added so that the audio framework can get flexibility for each audio stream routing pipeline and the control of the volume of input/output stream. For the platform storage management, Storage Access Framework (SAF) has been added. Vehicle services have been added to extend webOS Auto’s in-vehicle network coverage.

Rich Connectivity

webOS Auto’s connectivity features have been extended to include Wi-Fi Direct. Devices in the vicinity of the vehicle can easily interact with the applications running on the webOS Auto platform. Network interfaces have been designed to support multiple wired network interfaces as well as multiple Wi-Fi interfaces. This enables carmakers to use network interfaces for different roles. For example, you can assign one Ethernet interface for diagnostics and firmware updates and another for camera and video connection.

Security Enhancement

A wide range of security protection measures has been included and developed in the webOS Auto platform. In addition to PAM multi-user authentication functionality, several security improvements has been applied to bring webOS Auto in line with security standards for automotive vehicles. Threat Analysis and Risk Assessment (TARA) with ISO/SAE-21434 has been carried out on crucial components of the platform.The security of the digital key solution has been significantly improved to obtain FIPS certification. Federal Information Processing Standard Publication 140-3 (FIPS PUB 140-3) is a U.S. government computer security standard used to approve cryptographic modules.
