Abstract

An information service system for providing facility information includes: a restriction information obtaining device for obtaining restriction information relating to a driving condition or a user behavior; a preference information obtaining device for obtaining preference information of the user; a first information retrieving device for retrieving necessary facility information among multiple facility information items according to the restriction information; a second information retrieving device for retrieving preference facility information suited to the user preference among multiple necessary facility information items according to the preference information when the necessary facility information includes multiple necessary facility information items; and an information output device for outputting the necessary facility information or the preference facility information.

Claims

1. An information service system for providing facility information relating to a facility disposed around a current position of a vehicle, the system comprising:

a restriction information obtaining device for obtaining restriction information indicative of a restriction condition of at least one of a driving condition of the vehicle and a behavior of an user of the system;

a preference information obtaining device for obtaining preference information indicative of preference of the user;

a first information retrieving device for retrieving necessary facility information for the user among a plurality of facility information items in the facility information according to the restriction information;

a second information retrieving device for retrieving preference facility information suited to the preference of the user among a plurality of necessary facility information items in the necessary facility information according to the preference information when the necessary facility information includes the plurality of necessary facility information items; and

an information output device for outputting the necessary facility information retrieved by the first information retrieving device or the preference facility information retrieved by the first information retrieving device and the second information retrieving device.

2. The information service system according to claim 1, wherein:

the restriction information indicative of the restriction condition of the behavior of the user is defined as behavior restriction information;

the behavior restriction information indicates at least one of a destination, a driving date and a driving place;

the first information retrieving device estimates a driving purpose of the user based on the behavior restriction information; and

the first information retrieving device retrieves the necessary facility information suited to an estimated driving purpose.

3. The information service system according to claim 1, further comprising:

a first memory for storing the preference information in relation to each restriction information item in the restriction information, wherein;

the second information retrieving device reads out the preference information in the first memory corresponding to a restriction information item obtained by the restriction information obtaining device; and

the second information retrieving device retrieves the preference facility information based on a read-out preference information.

4. The information service system according to claim 1, further comprising:

a second memory for storing a preference level indicative of a preference degree of the user corresponding to each preference information item in the preference information, wherein;

the second information retrieving device reads out the preference level corresponding to a preference information item obtained by the preference information obtaining device; and

the second information retrieving device determines a limitation number of the facility information items, which are to be provided to the user, according to a read-out preference level.

5. The information service system according to claim 4, further comprising:

a feedback information obtaining device for obtaining feedback information indicative of at least one of an operation and the behavior, which are performed by the user in response to the necessary facility information or the preference facility information output by the information output device; and

a preference learning device for setting the preference level stored in the second memory variably according to the feedback information.

6. The information service system according to claim 1, further comprising:

a feedback information obtaining device for obtaining feedback information indicative of at least one of an operation and the behavior, which are performed by the user in response to the necessary facility information or the preference facility information output by the information output device, wherein;

the first information retrieving device deletes a facility information item relating to the at least one of the operation and the behavior performed by the user from the plurality of facility information items according to the feedback information.

7. The information service system according to claim 1, wherein:

the restriction information indicative of the restriction condition of the driving condition of the vehicle is defined as driving restriction information; and

the driving restriction information indicates a remaining amount of a power source in the vehicle.

8. A non-transitory tangible computer readable medium comprising instructions being executed by a computer, the instructions including the method for controlling the information service system according to claim 1, the method being computer-implemented.
