Modern approach to testing and validation of driver assistance systems

The ever-increasing demands of vehicle safety are forcing car manufacturers to develop ADAS systems (“intelligent assistants”). However, before starting sales of car equipped with such functions it is necessary to fully test and validate the algorithms for the operation of electronic systems in various conditions. Currently, the most popular methods for debugging and testing ADAS systems are based on "model-”, “software-" and "hardware-in-the-loop" modelling, which allows developers to identify and eliminate errors in the early stages of product development, thus saving money. Despite the enormous advantages of simulation, full-scale tests remain the fundamental and final stage before the start of mass production, this is due to the fact that international and Russia government standards currently don’t provide for the certification of “electronic assistants” through virtual tests. In this regard, manufacturers of measuring equipment and test-engineers are faced with the task of developing a new test setup that provides fixing the GNSS-position of vehicles in dynamic modes with centimeter accuracy, as well as making synchronized video recording. This article describes the approach of the employees of the NNTU n.a. R. E. Alekseev to the solution of this problem: the design of the concept and its implementation on a light commercial vehicle with ADAS systems. To fix coordinates with centimeter accuracy we have used Racelogic Vbox 100 Hz, operating in the RTK-mode, synchronized video recording was made using Racelogic Video Vbox Pro, which includes 4 wide-angle cameras. The approbation of the measuring installation was carried out when testing the following systems: a blind spot detector, a lane departure warning and a parking space search assistant. The article presents a number of graphs of the functioning of one of the systems.
