One hardware for different ADAS tests
Every modern vehicle is equipped with advanced driver assistance systems (ADAS). One of the challenges of ADAS testing is to precisely measure relative position and velocity from car to car when testing longitudinal control systems and to track the car in the testing of lateral control systems.
Adaptive cruise control
One of the challenges when testing the longitudinal control system, ACC is measuring precisely the relative position and velocity between two or more vehicles (sheer in/out manoeuvres). But the most important feature for gaining high-quality measurement data is perfect synchronization of all signal sources.
Autonomous emergency brake
AEB tests according to Euro NCAP standards require relative measurements to a virtual vehicle target
(balloon car) that does only carry an IMU for determining the absolute position. Normally,
the position data is transmitted over Wi-Fi.
In addition, driving robotics is needed to control the longitudinal and lateral movement of the vehicles during the test to ensure the repeatability of the test. DEWETRON’s mixed signal approach to acquire synchronized input signals from all sources is essential for the accuracy and the comparability of the data.
Forwarding collision warning
The main goal of FCW tests is to measure when the driver is warned of an imminent crash, as the warning might be available on the CAN bus much earlier than the acoustic/haptic warning.
Before being approved for the US market, vehicle manufacturers who offer FCW have to test their system to comply with the FCW confirmation test defined by the National Highway Traffic Safety Administration. The DEWETRON systems for FCW tests are fully compliant to the NHTSA requirements and specifications.
For tests of lateral control systems such as lane departure warning or lane keeping assistant (LDW/LKA), the measurement system needs to calculate the relative position, angle and velocity between the vehicle and stationary objects, such as lines, curbs or traffic signs. Moreover, the acquisition of synchronized video data is important for such tests.
2. Vehicle Dynamics testing
Many maneuvers have been standardized to assess the ride and handling capabilities of a vehicle. DEWETRON systems are well established in vehicle dynamics measurements because of their ease of use, their flexibility and their compatibility with virtually every sensor available.
Visualization of vehicle dynamics testing maneuver
The visualization of the vehicles movement during the test maneuver, with all its lines and cones, combined with graphs and video, provides comprehensive data results.
3. Simultaneous Durability testing with high channel count
DEWETRON measurement systems with a high channel count are perfect for durability measurements during real test drives or on testbeds – for a whole vehicle or specific components.
DEWETRON systems offer a rugged and portable design for in-vehicle use and fulfill the requirement for high channel counts.
Durability or road load data tests are typically high-channel count measurements that require scalable hardware in combination with powerful software features to process the configuration, monitoring, and acquisition of hundreds of channels simultaneously.
As the data acquired during real test drives is often replayed on test-beds to simulate material fatigue during the vehicle life-cycle, the analog output of the conditioned sensor signals is essential.
4. E-Mobility Testing and Analyzing
Battery powered vehicles are becoming more and more common on our roads and in our lives. DEWETRON is your competent partner to analyze, test and verify e-bikes, e-scooters and other electric vehicles during real drive tests.
Combination of combustion analyzer & power analyzer
With the combustion analyzer – a powerful tool for the analysis of combustion engines – and the DEWETRON power software – used for the analysis of electrical power grids – DEWETRON provides the ideal solution for both fields.
While both modules can be run independently to perform measurements on either combustion engines or pure electrical engines, they can also be parallelized to become the perfect tool for testing hybrid vehicles and sheer electric vehicles.
