Method and apparatus for determining a detour route in the case of a motor vehicle with a non-activated navigation system

摘要

A navigation system (2) in a motor vehicle is usually active only when a destination has been entered beforehand, so that the navigation system (2) a suitable route can be calculated to the destination. Frequently, the problem arises that, for example, in the case of a city driving no point of destination in the navigation system (2) has been entered. This can, for example, in the case of a jam from the navigation system, no suitable detour route are calculated. According to the invention is therefore proposed that the navigation system (2) a probability for the further path of travel is determined, and in this case determines whether on the planned further path of travel or in the vicinity of a traffic disruption is present. In this case, in the dialogue with the driver of a suitable detour route is calculated and output. This supports the navigation system (2) the driver of the motor vehicle in the event of unforeseen traffic disruptions in an advantageous manner, without a destination has to be programmed.
