ADAS Test Bench
ADAS Test Bench
Data Logging for the Validation of Modern Advanced Driver Assistance Systems
Modern advanced driver assistance systems must reliably detect and respond to complex traffic situations. ADAS test benches are used to systematically test functions such as lane keeping assistance, automatic emergency braking, and adaptive cruise control during the development process. They enable reproducible testing under controlled conditions and make it easier to compare different software and system versions. The resulting sensor, ECU, and test data is recorded simultaneously, making test results traceable and enabling targeted analysis of anomalies.
Typical Test Setup
Test Setup and Data Acquisition for the ADAS Test Bench
An ADAS test bench replicates typical driving scenarios under controlled conditions. Depending on the test objective, individual components, ECUs, or complete driver assistance functions are integrated into the test setup and complemented by simulation or hardware-in-the-loop (HiL) systems. This allows defined test cases to be repeated and different development versions to be compared objectively. During testing, relevant data from vehicle components, sensors, and the test environment is captured and subsequently analyzed together.

Capturing Large Volumes of Data from Multiple Sources
Interfaces
Automotive Ethernet, CAN / CAN FD, and More
Bandwidth
Data Throughput: 2–16 Gbit/s Storage Requirements: 2–32 TB
Test Setup & Test Environment
An ADAS test bench connects the components under test to a controlled test and simulation environment. The systems integrated into the setup depend on the function being tested and the respective stage of development.
Typical components include:
- ADAS ECUs
- Camera, radar, and LiDAR systems
- Simulation and HiL systems
- Restbus simulations
- Data loggers and probes
- Test bench and measurement systems
This setup allows both individual components and larger system configurations to be tested in a targeted manner.
Test Procedure & Execution
First, a defined test case is set up on the test bench. The simulation or HiL system then provides the specified driving, environmental, and vehicle conditions.
During the test, the integrated ECUs and components respond to these predefined conditions. At the same time, all data relevant to subsequent evaluation is recorded. After the test, the results can be analyzed and compared with previous test runs or different software versions.
The same test case can be repeated under comparable conditions, making it easier to evaluate changes and systematically identify and isolate faults.
Data Sources & Interfaces
An ADAS test bench generates data from multiple sources simultaneously. This includes data from ECUs, sensors, and the test and simulation environment.
Typical interfaces include:
- Automotive Ethernet, particularly 100BASE-T1 and 1000BASE-T1
- CAN and CAN FD
- LIN or FlexRay, depending on the test setup
- Analog and digital signals from the test bench and measurement equipment
The interfaces required for a specific test depend on the device under test (DUT), the test objective, and the system architecture.
Data Logging Requirements
ADAS tests can generate large volumes of data, particularly when high-bandwidth Ethernet connections and multiple vehicle buses are recorded simultaneously.
For ADAS test benches, aggregate data rates of 2 to 16 Gbit/s and storage requirements of 2 to 32 TB are typical. The actual values depend on the test setup, the number of data sources, and the recording duration.
In addition, the various data streams must be captured together and time-aligned for subsequent analysis. Depending on the test procedure, both extended continuous recordings and targeted snapshots can be used.
Challenges in Test Operations
A key challenge is reliably capturing data from different sources within a single test setup.
Typical challenges include:
- High data volumes from Automotive Ethernet
- Simultaneous recording of multiple vehicle buses
- Time synchronization of different data sources
- Long or extensive test series
- Reproducible data capture for identical test cases
- Adapting data acquisition to different test setups
As the functionality of an ADAS system increases, both the number of required interfaces and the volume of generated data can grow significantly.
Data Analysis & Post-Processing
After the test, the recorded data is made available for further analysis. The goal is to understand the behavior of the system under test and investigate relevant events in detail.
Individual test sequences can be selected, communication data can be analyzed, and different test runs can be compared.
Depending on the test setup, additional functions and protocols such as XCP, DLT, or TCP, as well as analysis tools such as esotrace, can be integrated into the test process. The specific tools and processing steps required depend on the respective test environment.
