Vector Releases PREEvision 26.3 for AUTOSAR and Android Integration

Vector PREEvision 26.3 Simplifies Mixed AUTOSAR and Android Architectures

Vector Informatik GmbH (Vector) has released PREEvision 26.3, introducing support for mixed AUTOSAR and Android architectures and simplifying the integration of Android applications into existing E/E systems. The release is aimed particularly at large development projects where multiple software and electrical/electronic architecture requirements must be managed consistently. By extending PREEvision’s architecture capabilities, the new version provides developers with a more streamlined approach to combining AUTOSAR-based systems with Android applications. The update also focuses on improving development efficiency, validation accuracy, and the reliability of engineering results across complex automotive development environments.

Optimized AUTOSAR Exports and Consistency Checks

PREEvision 26.3 introduces optimized AUTOSAR exports together with automatic consistency checks that deliver more precise results. These improvements are designed to make development processes faster while increasing confidence in the quality and reliability of engineering outputs. The enhanced validation mechanisms are particularly relevant to large development projects, where architectural changes and interconnected system elements can create complex consistency requirements. By providing more precise automated checks, Vector Informatik GmbH aims to help development teams identify issues more effectively and maintain dependable engineering results throughout the development process.

Improved Ethernet and Diagnostic Modeling

The new release also simplifies Ethernet communication design by allowing signals to be configured for transmission through the AUTOSAR LdCom (Large Data Communication) module. PREEvision 26.3 further enhances diagnostic functions by supporting the modeling of diagnostic events, diagnostic trouble codes (DTCs), and diagnostic displays. These capabilities extend the tool’s support for communication and diagnostic engineering within the same development environment. For teams working on complex E/E architectures, the combination of simplified Ethernet signal configuration and expanded diagnostic modeling can help organize system information more effectively while supporting more reliable validation of the resulting architecture.

Browser-Based Requirements Engineering and Future Technology

Requirements management receives an additional improvement through the Requirements Engineering Web Client, which enables users to modify requirements through a browser while automatically synchronizing those changes with the database. This provides a more flexible way to work with requirements without requiring users to rely exclusively on a local engineering interface. Vector Informatik GmbH has also included technology previews and beta features for upcoming extensions in PREEvision 26.3. These areas include historic baselines, PostgreSQL, and AI-powered functions, including MCP support, providing an indication of the technologies being explored for future versions.

Impact on Automotive E/E Development

PREEvision 26.3 brings together architecture integration, AUTOSAR export improvements, automated consistency checking, Ethernet communication configuration, diagnostic modeling, and browser-based requirements management in one release. Its support for mixed AUTOSAR and Android architectures is particularly significant for development environments that need to integrate Android applications with existing E/E systems. The combination of current improvements and preview features also extends the platform toward future database and AI-related capabilities. For engineering organizations managing large and complex vehicle development programs, Vector Informatik GmbH positions this release as an update focused on faster processes and more reliable development results.
