Abstract
Abstract In a vehicle navigation system, when a voice control part, which is displayed on a screen, is switched off, a voice control part inhibits voice guidance from being output to a speaker. Now, if a current-location/guide selection key is operated, the voice control part creates voice guidance according to the operation of the selection key and outputs the voice guidance from the speaker. With this navigation system, aural route guiding is possible only at the driver's request.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
A vehicle navigation system comprising: (a) map information storage means; (b) route computing means for searching a route to an intended destination of a vehicle using the map information stored in said map information storage means; (c) route guide and control means for displaying the computed route on a display screen and for outputting voice guidance via a speaker; (d) on-off selecting means for selecting whether or not the voice guidance should be output; (e) inhibition means for inhibiting outputting of the voice guidance if said on-off selecting means selects that the voice guidance should not be output; (f) input means for inputting a request for outputting the voice guidance; (g) voice guidance creating means for creating the voice guidance in response to the output request from said input means; and (h) voice guidance output means for releasing the inhibition status of said inhibition means for a predetermined period of time to output the voice guidance created by said voice guidance creating means.
