Route searching apparatus

摘要

The present invention provides a route consideration apparatus which can reduce amount of road geometry data to a necessary and sufficient volume to be managed, foreseeing probable routes by selecting branch roads appropriately. The route assessor 5 designates three route at maximum, i.e., the first prior route to the third prior route, according to the data inputted from the navigator. The curve geometry detector 6 detects rode geometry according to inputted data from the navigator 3. Thus previewing of route to be traveled can be carried out effectively and the vehicle dynamic control system works well with the previewing function (Fig. 1).
