Method for provision of local meteorological data i.e. ambient temperature, to user for driving motor car, involves assigning meteorological data of road map in position to construct weather chart, and providing weather chart to users

摘要

The method involves detecting meteorological data i.e. ambient temperature, in an environment of motor cars by an external temperature sensor (TS). A detecting position of the motor cars is determined by a portable navigation apparatus (NG). The meteorological data and the determined position are transmitted by a communication interface (KS) over a communication link (KV) to a central office (ZS). The meteorological data of a digital road map is assigned by the office in the detecting position to construct a current weather chart, and the weather chart is provided to users. The central office is an internet server.
