Abstract
Abstract A vehicle navigation system for orally issuing route guidance, capable of changing a point at which the route guidance is issued depending on the moving situation of a vehicle. The moving situation is at least one of a number of lanes in a road being traveled, a width of a crossroad intersecting the road being traveled and a speed of the vehicle. The moving situation is detected by a moving situation detector section and based on the detected moving situation, the route guidance issuing point is changed to the optimum point for the moving situation at that time by a guidance issuing point changer of a route guide controller.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A navigation system for issuing a route guidance for a vehicle orally as voice guidance, said system comprising: means for storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; means for detecting a number of lanes of said road being traveled; means for calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected number of lanes, said calculating means calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected number of lanes increases; and means for issuing said voice guidance at said position for issuing said voice guidance.
Claim 2
Dependent Claim
135 words

Claim 3
Dependent Claim
140 words
A navigation system for issuing a route guidance for a vehicle orally as voice guidance, said system comprising: means for storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; means for detecting a width of a crossroad intersecting said road being traveled at said branch point; means for calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected width of said crossroad, said calculating means calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected road width increases; and means for issuing said voice guidance at said position for issuing said voice guidance.
Claim 4
Dependent Claim
140 words
A navigation system for issuing a route guidance for a vehicle orally as voice guidance, said system comprising: means for storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; means for detecting a width of a crossroad intersecting said road being traveled at said branch point; means for calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected width of said crossroad, said calculating means calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected road width increases; and means for issuing said voice guidance at said position for issuing said voice guidance.
Claim 5
Dependent Claim
26 words
A navigation system according to claim 2, wherein said width of said crossroad is calculated on a basis of a number of lanes in said crossroad.
Claim 6
Dependent Claim
131 words
A navigation method for carrying out a navigation of a vehicle utilizing a voice guidance, said method comprising the steps of: storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; detecting a number of lanes in said road being traveled; calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected number of lanes, said calculating step including calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected number of lanes increases; and issuing said voice guidance at said position for issuing said voice guidance.
Claim 7
Dependent Claim
131 words
A navigation method for carrying out a navigation of a vehicle utilizing a voice guidance, said method comprising the steps of: storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; detecting a number of lanes in said road being traveled; calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected number of lanes, said calculating step including calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected number of lanes increases; and issuing said voice guidance at said position for issuing said voice guidance.
Claim 8
Dependent Claim
136 words
A navigation method for carrying out a navigation of a vehicle utilizing a voice guidance, said method comprising the steps of: storing route information required to reach a destination, said route information including information of a branch point on a road being traveled by said vehicle to be an object of said voice guidance; detecting a width of a crossroad intersecting said road being traveled at said branch point; calculating a position for issuing said voice guidance before said vehicle reaches said branch point in accordance with said detected width of said crossroad, said calculating step including calculating said position for issuing said voice guidance at a position which is increasingly further away from said branch point as said detected road width increases; and issuing said voice guidance at said position for issuing said voice guidance.
