Abstract
Abstract A navigation apparatus for a movable body is provided with: a measurement device (1, 2, 3, 4) for measuring a present position of the movable body; a setting device (11, 7) for setting route position information corresponding to a plurality of scheduled route positions which are scheduled to be passed on a route to a destination; a memory device (9) for storing the present position at predetermined time intervals as passed position information between a start time, which is a time when the setting device starts to set the route position information, and an end time, which is a time when the setting device ends to set the route position information; a judgement device (7) for judging whether or not the movable body has passed the scheduled route positions between the start time and the end time on the basis of the passed position information stored in the memory device, after the end time; and a guidance device (13, 18) for generating a message to guide the movable body from the measured present position to the destination on the basis of the scheduled route positions which the movable body has not passed yet according to a judgement result of the judgement device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
203 words
A navigation apparatus for a movable body comprising measurement means (1, 2, 3, 4) for measuring a present position of said movable body, characterized in that said navigation apparatus further comprises: setting means (11, 7) for setting route position information corresponding to a plurality of scheduled route positions which are scheduled to be passed on a route to a destination; memory means (9) for storing the present position at predetermined time intervals as passed position information between a start time, which is a time when said setting means starts to set the route position information, and an end time, which is a time when said setting means ends to set the route position information; judgement means (7) for judging whether or not said movable body has passed the scheduled route positions between the start time and the end time on the basis of the passed position information stored in said memory means, after the end time; and guidance means (13, 18) for generating a message to guide said movable body from the measured present position to the destination on the basis of the scheduled route positions which said movable body has not passed yet according to a judgement result of said judgement means.
Claim 2
Dependent Claim
40 words
A navigation apparatus according to claim 1, characterized in that said measurement means comprises at least one of a geomagnetic sensor (1), an angular speed sensor (2), a travel distance sensor (3) and a GPS (Global Positioning System) receiver (4).
Claim 3
Dependent Claim
31 words
A navigation apparatus according to claim 1 or claim 2, characterized in that said setting means comprises an input means (11) through which the route position information can be manually set.
Claim 4
Dependent Claim
34 words
A navigation apparatus according to claim 1 or claim 2, characterized in that said setting means comprises means (7) for automatically set the route position information in correspondence with the route to the destination.
Claim 5
Dependent Claim
27 words
A navigation apparatus according to any one of claims 1 to 4, characterized in that said guidance means comprises a display means (13) for displaying the message.
Claim 6
Dependent Claim
32 words
A navigation apparatus according to any one of claims 1 to 5, characterized in that said guidance means comprises a voice outputting means (18) for outputting the message by a synthetic voice.
Claim 7
Dependent Claim
44 words
A navigation apparatus according to any one of claims 1 to 6, characterized in that said memory means comprises a ring buffer (9) for updating the stored passed position information one after another as the present position is newly detected by the measurement means.
Claim 8
Dependent Claim
181 words
A navigation method for a movable body comprising the step of measuring a present position of said movable body, characterized in that said navigation method further comprises: setting route position information corresponding to a plurality of scheduled route positions which are scheduled to be passed on a route to a destination; storing the present position at predetermined time intervals as passed position information between a start time, which is a time when said setting means starts to set the route position information, and an end time, which is a time when said setting means ends to set the route position information; judging whether or not said movable body has passed the scheduled route positions between the start time and the end time on the basis of the passed position information stored in the storing step, after the end time; and generating a message to guide said movable body from the measured present position to the destination on the basis of the scheduled route positions which said movable body has not passed yet according to a judgement result in the judging step.
Claim 9
Dependent Claim
46 words
A navigation method according to claim 8, characterized in that, in the measuring step, the present position is measured by at least one of a geomagnetic sensor (1), an angular speed sensor (2), a travel distance sensor (3) and a GPS (Global Positioning System) receiver (4).
Claim 10
Dependent Claim
24 words
A navigation method according to claim 8 or claim 9, characterized in that, in the setting step, the route position information is manually set.
Claim 11
Dependent Claim
32 words
A navigation method according to claim 8 or claim 9, characterized in that, in the setting step, the route position information is automatically set in correspondence with the route to the destination.
Claim 12
Dependent Claim
25 words
A navigation method according to any one of claims 8 to 11, characterized in that the generating step comprises the step of displaying the message.
Claim 13
Dependent Claim
29 words
A navigation method according to any one of claims 8 to 12, characterized in that the generating step comprises the step of outputting the message by a synthetic voice.
Claim 14
Dependent Claim
