about
In the field of development, we can offer you a stable development framework and a mature development process based on our over the years accumulated experiences and know-how. The framework can guarantee the stability and the functional safety of the developed systems. Our design methods and processes offer different possibilities and the maximum possible flexibility. According to system requirements, we provide customized services as well as customized designs and hardware selection services to all our customers; if customer-specified hardware is present, we can also provide hardware calibration, and design systems based on the calibration results. Thus, while meeting the design requirements of various systems, the optimization of the cost-performance ratio can be guaranteed as well.
Validation of Driver Assistance Systems

In the field of driver assistance system validation, ZD (Beijing) automotive technology Co., Ltd. provides various validation services. According to the international standard ISO26262, our company provides validation services, which can cover the whole development process of driver assistance systems. The provided services include the model-in-the-loop tests for conceptual system design, the software-in-the-loop tests for software development, the hardware-in-the-loop tests for system hardware development and the road tests with real vehicles.

In the validation that accompanies the whole development process, in addition to providing experienced engineering personnel to help customers to test systems, we can also design test strategies and test cases for customers based on our experience. Thus, the maximum test coverage of the validation tests can be ensured, and the errors and design flaws in the system can be identified as early as possible. In this way, the risk of possible large-scale debugging and reconstruction in a latter development phase can be reduced. In addition, we can optimize the existing validation strategies based on experience, reduce the test scope to a reasonable range and achieve cost as well as time reductions.

Test Devices for the Development and Validation of Driver Assistance Systems

ZD (Beijing) Automotive Technology Co. Ltd. has developed various test tools and devices for the driver assistant system development and validation, e.g. simulation-based test environment, mobile traffic information collection system, and automated driving prototype.


about

The simulation-based test environment can reproduce the road traffic and driving environment in a computational virtual environment, to test efficiently and conveniently whether the driving system can accomplish the expected driving tasks in various driving environments. This kind of test environment is recognized as one of the major validation methods for automated driving systems. In addition to the simulation-based test environment, we also provide high-fidelity physics models of vehicle components, such as millimeter-wave-radar model, lidar model and vehicle dynamics model, which are compatible with most well-known simulation software. Thus, it is possible to provide multiple options to customers for obtaining more accurate test data and achieving better validation results.

The mobile traffic information collection system helps customers to obtain and record real traffic conditions and driving environment information. By loading this information into the simulation-based test environment, the customers can experience real road conditions and receive driving environment information for testing the system at anytime and anywhere. Compared to the traditional one-test-per-change method, which executes a real vehicle test each time the system is modified, this method can greatly achieve time and cost savings.

Due to an automated driving prototype, we can provide our customers with a possibility to build a system prototype. In the premise of hardware generalization, we can build prototypes, which provide customers with a programmable system interface, so that customers can quickly and easily modify the sensor data processing algorithms, the algorithms for system controllers and the system algorithm itself, according to their own needs and wishes. Furthermore, the prototype can be used for an intuitive release of new products and functions as well.
