Driver assistance system for more safety and comfort in road traffic; State-of-the-art display concept shows different images depending on viewing angle

Rüsselsheim/Pferdsfeld. General Motors presents innovations for the future of automotive mobility during a technology workshop at its Test Center in Pferdsfeld, which was recently completely modernized. Taking center stage are a state-of-the-art driver assistance system with innovative sensor technology, and a new LCD-based display technology, which GM presents in a car for the first time and could soon replace conventional screens. “In the development of new technologies, GM’s main objective is to support the driver and therefore improve safety and comfort in road traffic,” says Hans H. Demant, Vice President, Engineering, General Motors Europe and Managing Director, Adam Opel AG. “GM also underlines its commitment to continue to take a leading role in innovations in the future.”
Adaptive distance/speed control and lane-holding assistant for safer traffic

GM engineers have developed a driver assistance system with adaptive distance and speed control, which also includes a lane-holding assistant, enabling the correction of unintentional drifting. The driver assistance system automatically maintains a constant safety zone to the vehicle ahead in all driving conditions, from stop-and-go traffic to high-speed highway driving. Various sensors monitor the car’s environment. Software analyzes the information and transmits it to different applications. The clever system uses road data, along with specially developed, enhanced power steering, to stay on track – in other words, the vehicle steers automatically to correct deviations from the center of the lane.

With this system, GM goes far beyond all applications currently available in production models, such as strictly distance or lane-holding systems. The system uses lidar sensors (Light Detection and Ranging) – a measuring technology comparable to radar, but using laser. Laser sensors have a similar range to radar sensors, but a significantly larger field of view and higher horizontal resolution. In addition, lidar sensors detect limited visibility conditions such as fog or snow.

DualView display shows different images depending on viewing angle

General Motors is the first automaker in the world to present the state-of-the-art DualView display, which was developed by the Japanese electronics company Sharp and integrated into an Opel Vectra station wagon by GM engineers for testing purposes. This technology enables the display of two different images on a single LCD (Liquid Crystal Display) screen. While the driver sees navigation system information, for example, the front passenger can watch a DVD film. The advantage for drivers: they are not distracted by moving images on a second monitor and still have all relevant information from the onboard computer or navigation system in their view.

GM engineers are currently working on getting these innovative technologies, which are already fully suitable for everyday use, ready for production. The driver assistance system and DualView display are designed in such a way that they can be used in various GM markets, brands and models. Hans Demant says, “In development to production maturity, the future costs for customers play an important role, as it is GM’s philosophy to make smart innovations available to as many drivers as possible at affordable prices.”
