With the increasing electrification of modern automobiles, automotive bus systems are becoming increasingly complex. Among them, FlexRay, as a high-speed and reliable automotive network communication protocol, has been widely used in automotive electronic systems. To ensure the normal operation of vehicle electronic systems and ensure the safety and reliability of vehicles, automotive bus testing has become a critically important task.

VCARSYSTEM's Solution

VCARSYSTEM provides an advanced and efficient Vehicle FlexRay Testing Solution. This solution connects the tested ECU with VCI4422 and utilizes VCAR DAS software to monitor and analyze bus information in real-time, achieving comprehensive testing of the FlexRay bus system. The system supports various testing requirements including functionality, performance, fault tolerance, safety, timing and synchronization, integration testing, as well as load and stability testing.

Workflow

Functions

Functional Testing:

Frame Send and Receive Testing: verify each node's capability to correctly send and receive FlexRay frames, including static and dynamic frames.

Message Periodicity Testing: Ensure periodic messages are sent and received on time.

Non-periodic Message Testing: Test the sending and receiving functionality of non-periodic messages.

Request-Response Communication Testing Between Nodes: Test the transmission of request and response messages between nodes.

Performance Testing:

Bandwidth and Throughput Testing: Evaluate the maximum bandwidth and throughput of the FlexRay network to ensure it meets real-time requirements.

Message Latency Testing: Measure the delay between message transmission and reception to ensure network response times meet requirements.

Clock Synchronization Testing: Verify the clock synchronization performance of all nodes to ensure coordinated communication behavior between nodes.

Fault Tolerance Testing:

Error Frame Handling Testing: Test node capabilities to handle error frames, including error detection and error recovery mechanisms.

Redundant Communication Testing: Verify the redundancy and fault tolerance capabilities of the FlexRay network to ensure normal operation in case of node failures.

Security Testing:

Data Integrity and Security Testing: Verify message integrity to prevent data tampering and injection attacks, and test authentication and encryption mechanisms.

Access Control Testing: Ensure only authorized nodes can access the network to prevent unauthorized access.

Timing and Synchronization Testing:

Node Startup and Shutdown Testing: Test node startup and shutdown processes, including automatic restart and state recovery.

Timing Consistency Testing: Verify if message transmission and reception timing is consistent to ensure good real-time and synchronization performance.

Integration Testing:
