Abstract:
A road shape determining device for determining the shape of a road ahead of the position of a vehicle on the basis of road data, comprisinga road azimuth angle calculating means for calculating an azimuth angle (.theta.1, .theta.2) of the road ahead of the vehicle on the basis of the road data;a movement azimuth angle calculating means for calculating an azimuth angle (.theta.V) of movement of the vehicle; anda road shape determining means coupled to said road azimuth angle calculating means and said movement angle calculating means, for determining the shape of the road ahead of the position of the vehicle by comparing the road azimuth angle (.theta.1, .theta.2) calculated by said road azimuth angle calculating means with the azimuth angle (.theta.V) of movement of the vehicle calculated by said movement azimuth angle calculating means.
