Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
222 words
A running guide system for a motor vehicle comprising: running distance detecting means for detecting an actual running distance travelled by the motor vehicle; memory means for storing a plurality of maps arranged according to a predetermined sequence illustrating a route from a start point to a destination, each of said maps containing a segment of said route and overlapping with a segment of an adjacent map in said sequence; display means for displaying each map stored in said memory means; changing means, connected to said running distance detecting means, memory means and display means, for changing a map currently displayed by said display means to a next map in said sequence of maps showing a next segment of said route when the actual running distance coincides with a predetermined running distance of the currently displayed map; tape recorder means for playing a cassette tape and generating a tape signal for causing the display of a map by said display means; judging means, responsive to the tape signal, for judging whether or not the tape signal is indicative of a music tape or a map information tape; and rewinding means, responsive to a signal from said judging means, for fully rewinding said cassette tape to a beginning point thereof when an indication of the map information is judged by said judging means.

A running guide system for a motor vehicle comprising: running distance detecting means for detecting an actual running distance travelled by the motor vehicle; memory means for storing a plurality of maps arranged according to a predetermined sequence illustrating a route from a start point to a destination, each of said maps containing a segment of said route and overlapping with a segment of an adjacent map in said sequence; display means for displaying each map stored in said memory means; changing means, connected to said running distance detecting means, memory means and display means, for changing a map currently displayed by said display means to a next map in said sequence of maps showing a next segment of said route when the actual running distance coincides with a predetermined running distance of the currently displayed map; tape recorder means for playing a cassette tape and generating a tape signal for causing the display of a map by said display means; judging means, responsive to the tape signal, for judging whether or not the tape signal is indicative of a music tape or a map information tape; and rewinding means, responsive to a signal from said judging means, for fully rewinding said cassette tape to a beginning point thereof when an indication of the map information is judged by said judging means.
Claim 3
Dependent Claim
241 words
A running guide system for a motor vehicle comprising: running distance detecting means for detecting an actual running distance travelled by said motor vehicle; memory means for storing a plurality of maps in a predetermined sequence illustrating a route from a start point to a destination, each of said maps containing a segment of said route and overlapping with a segment of an adjacent map in said sequence; display means for displaying each said map stored in said memory means; changing means, connected to said running distance detecting means, memory means and said display means, for changing a map currently displayed on said display means to a next map in said sequence showing the predetermined next segment of said route when the actual running distance coincide with the running distance predetermined for each map; voice generating means for announcing a notice of renewal of the map currently displayed prior to the actual renewal of the map; tape recorder means for displaying a cassette tape and generating a tape signal for causing the display of a map by said display means; judging means, responsive to the tape signal, for judging whether or not the tape signal is indicative of a music tape or a map information tape; and rewinding means, responsive to a signal from said jugding means, for fully rewinding said cassette tape to a beginning point thereof when an indication of the map information is judged by said judging means.
