As the automotive industry advances in its "New Four Modernizations" drive, the number and complexity of in-vehicle electronic control units (ECUs) continue to grow. To address the challenges of traditional automotive electronic architectures in interaction and change management, Service-Oriented Architecture (SOA) has been introduced into the automotive sector. However, the high costs of building simulation environments, the difficulties in developing complex test cases and scripts, and the lack of implementation experience have made early-stage testing fraught with challenges. Consequently, the testing and validation of SOA software has become a new challenge for the industry.

VCARSYSTEM's Solution

VCARSYSTEM’s SOA Service Testing Solution supports the import of multiple databases, as well as the simulation of SOME/IP, DDS, and OEM proprietary protocol nodes. It also covers a comprehensive range of functional and performance tests, addressing the testing requirements for automotive electronic software in a software-defined vehicle (SDV) environment. Furthermore, the solution can be expanded into a vehicle network bus testing system to conduct protocol layer testing for Ethernet, CAN, and LIN buses on domain controllers — ensuring the reliability and stability of automotive electronic systems.

VCAR DAS

VCAR DAS combines automotive bus simulation, analysis, testing, diagnosis, database editing, calibration testing, and radar, video, and GPS data monitoring. It supports CAPL scripts and Automotive Ethernet communication protocol, featuring node simulation, diagnostic flashing, database editing, and parsing. Additionally, it facilitates automated development testing and is applicable in various scenarios like network development, simulation, testing, calibration and measurement, ECU/Vehicle development, and diagnostics flashing.

HIL SYSTEM

VCARSYSTEM offers Hardware-in-the-Loop (HIL) testing solutions that cover the entire scope of automotive electronics, including modules for new energy powertrain systems (BMS/VCU/MCU), automotive driving systems (ACC/LKA/AEB, etc.), chassis electronic control systems (EPS/ESP/SBW/EPB/EHB/EMB), traditional powertrain systems (EMS/TCU), as well as body electronics and intelligent cockpits. It provides comprehensive HIL testing services to help customers accelerate product launch timelines.

WORKFLOW

The system includes an upper computer running VCARSYSTEM’s automated testing software, VCAR DAS, and a test cabinet with bus communication cards, fault injection units, signal cards, power control modules, and real-time processing systems.

ADVANTAGES

Equipped with Self-Developed Real-Time Processing System

The system is equipped with VCARSYSTEM’s high-performance real-time processing system RTPC, ensuring high reliability and stability during the testing process, while efficiently processing data, reducing latency, and minimizing errors.

Reduced External Dependencies

The system design minimizes reliance on external data generation nodes and services, offering customers a more convenient testing solution and enhancing both the efficiency and autonomy of the testing process.

Supports Custom Development

Custom software modules can be developed based on OEM proprietary protocols, significantly increasing the flexibility and practicality of testing to meet specific testing requirements.

Multi-User Parallel Testing

Supports simultaneous access by multiple users to conduct asynchronous functional testing, allowing parallel handling of multiple testing tasks, effectively improving team efficiency and the comprehensiveness and effectiveness of tests.
