In addition to fuel-cell technology, researchers in his department are working with other types of alternative propulsion systems, including hybrid systems that combine a diesel engine in the front of the vehicle and an electrical engine in the rear. Intelligent cars that allow drivers to sit back and relax while the car drives itself are still a way off. Cars equipped with cruise control that responds to road and traffic conditions exist as prototypes. Researcher Stefan Hahn explained that these cars are equipped with cameras attached to the windshield. A computer inside the car analyzes the images.
Voice messages warn of obstacles, such as pedestrians.
The data base can even recognize the shape of legs, he said. While city cruise control won't be an option on DaimlerChrysler cars in the near future, the Mercedes S class is already equipped with a type of enhanced cruise control that maintains a safe distance from the car in front. Eventually the advances will be applied to lower-priced Mercedes and Chrysler products. But some new features, such as smart air bags, might be in all DaimlerChrysler vehicles soon. Hahn explained that these air bags are equipped with sensors that determine where the passenger is, as well as the size of the passenger.
