ZD Automotive and its partner develop various test tools for the validation of driver assistance systems, including mobile traffic information systems and automated driving prototypes as well as the simulation-based test tool GaiA.
When it comes to validation tools, the safety issues of the High-Level Automated Driving Systems (SAE Level 3-5, ADS) reveal more challenges than ADAS (SAE Level 1-2, Advanced Driver Assistance System). Unlike ADAS, the driver does not have to participate in the operation of high-level automated driving systems. According to the SAE, an ADS should be able to monitor the driving environment without a driver. This indicates higher requirements on the functional safety of the system as well as its validation.
To comply with these greater validation requirements, higher validation standards and a larger test case database is necessary. However, it increases the costs and bring up efficiency issues. To solve the challenges caused by ADS validation test and meet the requirements for its effectiveness and efficiency, the simulation-based test tool GaiA is an ideal solution.
GaiA can reproduce the road traffic as well as the vehicle in a virtual simulation environment to efficiently test whether the driving system can perform the expected tasks in different situations. This type of test system is the most important validation method for automated driving systems due to its low costs and ability to simulate large amounts of test drives.
In the user-friendly Interface, users can visualize any test scenarios in GaiA, which provides the following functions besides speed adjustment and data recording:
