Opel successfully presented a future that promises fewer accidents and greater freedom of movement so that the driver can read, write or rest instead of constantly watching the car.
The company participates in Ko-HAF (“Kooperatives hochautomatisiertes Fahren”), a German research project on collaborative, automated driving, launched in June 2015. Demonstration of this type of driving operations took place in the Insignia during the presentation of Ko-HAF’s final results at the Rodgau-Dudenhofen Brand Test Center.
Co-operative, automated driving systems do not require continuous supervision by the driver. Drivers can deal with other things, but when notified by the system, they must be able to take over the vehicle within a certain time. Therefore, the vehicle must be able to “see” longer than its own sensors allow.
In Ko-HAF, vehicles are sending information on current road conditions, such as road works, traffic jams and accidents, to a Safety Server.
The Safety Server collects and processes information, so if necessary, there is an exact map – like an artificial horizon that provides a very detailed overview of the road ahead.
At Ko-HAF, Opel took over the digitized maps sector as well as the process of disconnecting the car from automated driving mode and restoring control to the driver. The engineers from Rüsselsheim designed the architecture, interfaces and protocols of the Safety Server, evaluated in the project.
An additional basic task was to create a self-locking method (exact stigma) for the vehicle. Technicians have designed algorithms for visual mapping and positioning, integrated with data from centrally and locally stored maps, embedded sensors and the Global Navigation Satellite System (GNSS).
The detection method was tested in the Insignia prototype, in the Test Center, and in the Ko-HAF test route on motorways around Frankfurt.
