Validation environment for function development and coverage of ADAS in the car development process

Abstract

Advanced driver assistance systems in modern vehicles have achieved an important role with the result that more and more new cars will be equipped with such a system. In addition to the demand of more driving-comfort, the needs for safer vehicles [1] also increases and results in comprehensive and complex assistance systems, which enables almost autonomous driving. On the other hand the manufacturers have to save time and costs in development, which is for example possible by „from road to rig“ approaches [2]. In this way time consuming road tests will be either transferred to the reproducible test environment of test benches or are replaced by early componenttests in a virtual environment, which validates the desired system behavior. Before that background, this contribution shows approaches how advanced driver assistance systems (ADAS) in the entire vehicle can be tested on the test bench under reproducible, customer-oriented conditions, like traffic jam, by using suitable stimulators. The focus of the solutions is on roller test bench testing environments with minimal interference with the test vehicle. Based on this, the stimulation of ultrasonic-distance-sensors for parking assistance as „automotive ultrasonic target simulator“ will gain knowledge on the development process and demonstrates it then on the roller test bench. In order to keep the development of increasingly complex advanced driver assistance systems manageable, the so-designed validation environment provides the developer an approach to be able to test highly in car networked assistance systems quickly and under controlled as well as reproducible conditions.
