Abstract
A navigation system for an automotive vehicle includes a map data storage unit. The storage unit stores first known target points and adjoining target points preselected for each of the first target points from the first target points. The storage unit further stores a first data group associated with each of the first target points. Each of the first data groups includes a second data group corresponding to each of the adjoining target points of the corresponding first target point. Each of the second data groups includes an abstract configuration of the corresponding first target point and a travel information required at the corresponding first target point for going to the corresponding adjoining target point. The system selects second target points from the first target points to define a vehicle travel route. The system further selects one of the second data groups based on third and fourth target points selected from the second target points. The third target point is a next forward target point for the vehicle and the fourth target point is one of the adjoining target points of the third target point and positioned forward of the third target point. The third target point i…
