Driver information system operating method for motor vehicle, involves controlling position determination device by microprocessor, determining travel time to location, and comparing travel time with time assigned to task

摘要

The method involves connecting a control unit (20) with a position determining device (3) and a telephone unit (4) via respective interfaces (22, 23). Connection between a database (50) for user-dependent task management and the control unit is formed via a third interface (24). A task is selected from the database, and location and time are assigned to the task. The position determination device is controlled by a microprocessor, and travel time to the location is determined. The travel time and the time assigned to the task are compared.
