摘要 |
<p>The present invention is to prevent execution of a detour route search by the received VICS data where certain conditions are not met. To this end, a necessary time RT1 as taken for a land vehicle to move from its present location to arrive at a first forward point is calculated whereat the vehicle is expected to turn to the right or left along a route under guidance (step SB12). On the other hand, a time CT required to conduct a route re-search based oh VICS data is calculated (step SB14). By comparing the necessary time RT1 with time CT to determine which one is greater than the other (step SB16), if TR1 ≥ CT then a route re-search based on VICS data is performed (step SB18). However, if RT1 < CT then execution of the route re-search is eliminated. <IMAGE></p> |
