DRIVER ASSISTANCE: CONCEPTS AND SYSTEMS

Driver assistance systems are aimed at reducing the driver's workload and mitigating the consequences of specific driver deficiencies. In the case of adaptive cruise control, the results show that the task to keep a safe distance is simplified. The drivers' workload is perceptibly reduced, resulting in increased comfort. However, a suitable man/machine interface that reliably presents system function and actual system state is inevitable. Tests with radio data systems/traffic message channel (RDS/TMC) have been encouraging. Drivers appreciate real-time, precise traffic messages. However, there is still a need for major improvements in traffic measurement and observation. These systems and their integration represent steps toward a comprehensive concept of driver support. Main areas of current work include improving the performance of single functions as well as integration into overall design, where the focus is on the adaptability to individual drivers. In that respect, microelectronics and telematics will not lead to an electronic copilot that supervises the driver; they should increase efficiency and reliability of driver actions and contribute to a reduced mental load for the driver. The key is human-centered adaptation and integration.
