Positioning apparatus

A positioning apparatus comprising:

• a position detecting means in a vehicle for providing information indicative of a current position of said vehicle;
• a data input means for inputting control data for said positioning apparatus;
• a power-source supply means for providing power to at least one component of said positioning apparatus;
• a display means for indicating position data of said vehicle based on said information output from said position detecting means;
• and
• a position search means for computing a present position of said vehicle based on said information provided by said position detecting means and for outputting a control signal to shut off said power-source supply means if said vehicle is in a stopping state for a predetermined time-interval as determined by comparing said present position with a previously detected present position without operation of said data input means for said predetermined time-interval.

A positioning apparatus comprising:

• a position detecting means in a vehicle for providing information indicative of a current position of said vehicle;
• a power-source supply means for providing power to each component in said positioning apparatus;
• a display means for indicating position data of said vehicle based on said information output from said position detecting means;
• a position search means for computing a present position of said vehicle based on said information provided by said position detecting means and for outputting a first control signal to shut off a supply of power from said power-source supply means to a selected component of said positioning apparatus if said vehicle is in a stopping state for a predetermined first time-interval as determined by comparing said present position with a previously detected present position and further for outputting a second control signal to shut off said power-source supply means for said positioning apparatus when said vehicle is in a stopping state for a predetermined second time-interval that is longer than said predetermined first time-interval.

A positioning apparatus comprising:

• a position detecting means in a vehicle for providing information indicative of a current position of said vehicle;
• a data input means for inputting control data for said positioning apparatus and for selecting a component of said positioning apparatus to be shut off;
• a power-source supply means for providing power to each component in said positioning apparatus;
• a display means for indicating position data of said vehicle based on said information output from said position detecting means;
• a position search means for computing a present position of said vehicle based on said information provided by said position detecting means and for outputting a first control signal to shut off a supply of power from said power-source supply means to said component selected by said data input means if said vehicle is in a stopping state for a predetermined first time-interval as determined by comparing said present position with a previously detected present position and if said data input means is not operated for said predetermined first time-interval and further for outputting a second control signal to shut off said power-source supply means for said positioning apparatus if said vehicle is in a stopping state for a determined second time-interval without operation of said data input means for said predetermined second time-interval, said predetermined second time-interval being longer than said predetermined first time-interval.
