The assistance systems in modern vehicles are getting increasingly complex. More and more not only one's own vehicle is considered. New assistance systems support the driver depending on the traffic situation and reflect the surrounding road users in their decision. Such systems are grouped under the term "Advanced Driver Assistance Systems" (ADAS). Examples are: lane departure warning, active cruise control, forward collision warning, autonomous emergency braking, blind spot detection and monitoring, etc.
The major challenge in the development of these systems is to take into account the variety of traffic scenarios. Extensive tests with real vehicles or vehicle dummies are still indispensable instuments in the development and design of advanced driver assistance systems. Most systems are designed to support the driver in critical situations. This mostly for the test car and its occupants dangerous driving condition must be reproducibly obtained under test conditions in order to receive meaningful test data. As the driver assistance systems (ADAS) also include other road users, a testing scenario consists of at least 2 vehicles. For testing both vehicles have to take defined driving conditions (eg speed, deceleration, cornering, etc.) and in addition both have to comply with certain relative positions or distances to each other. Such complex test scenarios can be realized only with driving robots in a reproducible manner. Especially from the point of safety, many of the test cases can not be performed with human test drivers.
The VEHICO dynamic control systems CO.DRIVE and CO.SYNC offer in conjunction with the VEHICO driving robots the possibility to automate ADAS testing. Through quick installation of our driving robots an ADAS test vehicle can be upgraded in a short time to an automatically driving test vehicle. The vehicle itself must not be modified. The connection of various sensors is possible on our freely configurable CAN interface. Depending on the type of test our customers use systems from GeneSys, OxTS, Racelogic, iMAR or similar. Any other sensor may also be used, provided that it has a CAN interface. With our distributed system architecture the user has full flexibility to program each actuator (steering robot, brake robot, gas robot, etc.) individually. Each system can trigger another system or can be triggered by a different system. External signals or CAN signals can be used for triggering too. This allows to easily configure and implement even the most complex tests.
Benefits of the VEHICO ADAS test system:
- dangerous driving tests can be realized without a driver
- driving robot has higher accuracy and repeatability than human drivers
- fewer test runs due to higher quality test data
