Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a call response method for a vehicle, which is used in such a vehicle as an automobile when a call has been received from another system, and in particular to a call response method which can realize a call response based upon a safety drive of a driver, for example, even when a call including at least an image has been received.




2. Description of the Related Art




As a conventional apparatus for a call response in a vehicle, there has been a disclosed apparatus. The disclosure relates to subject matters contained in Japanese Patent Application Laid-Open No. HEI 10-304464, the disclosure of which is expressly incorporated herein by reference in its entirety. As disclosed in the Patent Application Laid-Open publication, for example, there has been well known a hand-free device which is mounted on such a vehicle as an automobile and is configured so as to be capable to responding to a call which has been received from another system.




In the above Patent Application Laid-Open publication, there has been disclosed a control method for a hand-free device which has been configured such that, during a telephonic communication, when it is predicted that a driving load may be increased within a predetermined interval or when it has been determined that a current state is in such an increased driving load state, the telephonic communication is reserved temporarily.




According to the control method for a hand-free device which has been disclosed in the publication, since during a telephonic communication, when it is predicted or expected that a driving load may be increased within predetermined intervals or when it has been determined that a current state is in such an increased driving load state, the telephonic communication is reserved temporarily, a response based upon a safety drive during a telephonic communication can be achieved.




However, in the above conventional method for controlling a telephone communication reservation, there is a drawback to be solved that, for example, when a call including at least image is received, a response to the call is performed by instantaneously presenting the image included in the received call to the driver so that the driver's eyes are temporarily attracted to the image, which leads to lack in his/her concentration to driving to obstruct attainment of a call response based on a safety drive, as a result.




A development of a novel technique which can attain a call response based upon a safety drive, for example, even when a call including at least an image is received has been expected.




SUMMARY OF THE INVENTION




The present invention has been attained in view of the above circumstances, and an object thereof is to provide a call response method for a vehicle, which can attain a call response based upon a safety drive, for example, even when a call including at least an image is received, by, when a call including at least an image is received in a vehicle from another system, performing a call reception previous notification for previously signaling a call reception at predetermined intervals to appeal to one sense of the senses of hear, smell and touch of a driver except for the sense of sight of a driver or a combination of at lease two of the senses, and, after performing the call reception previous notification except of the sense of sight, performing a call reception main notification for presenting the image included in the call to appeal to the sense of sight of the driver.




In order to achieve the object, according to a first aspect of the present invention, there is provided a call response method for a vehicle used in a vehicle to respond to a call received from another system, comprising the steps of: performing a call reception previous notification for previously signaling a call reception at a predetermined interval to appeal to one sense or a combination of at lease two senses among a sense of hearing, a sense of smell and a sense of touch of a driver except for a sense of sight of the driver when a call including at least an image is received in the vehicle from another system; and performing a call reception main notification for presenting the image included in the call to appeal to the sense of sight of the driver, after performing the call reception previous notification except of the sense of sight.




According to the first aspect, when a call including at least an image, is received in a vehicle, a call reception previous notification for previously signaling the reception of the call is performed only at a predetermined interval to appeal to one sense of the senses of hear, smell and touch of a driver except for his/her sense of sight or a combination of at lease two of the senses, and after the call reception previous notification except of the sense of sight has been performed, a call reception main notification for presenting the image included in the call is performed to appeal to the sense of sight of the driver. Therefore, for example, even when a call including at least an image is received, the call reception main notification which appeals to the sense of sight of the driver with an elapse of the predetermined intervals after the call reception previous notification has been performed is performed, so that a call response based upon a safety drive can be realized.




A second aspect of the invention is a call response method for a vehicle as it depends from the first aspect, wherein the call reception previous notification which appeals to the sense of hear of a driver generates a sound or voice for previously signaling a call reception.




According to the second aspect, the call reception previous notification for appealing to the sense of hear of a driver is performed by generating a sound or voice for previously signaling a call reception. Therefore, for example, even when a call including at least an image is received, with an elapse of the predetermined intervals after the call reception previous notification which does to appeal the sense of sight of a driver has been performed, the call reception main notification which appeals to the sense of sight of a driver is performed, so that a call response based upon a safety drive can be realized.




Also, a third aspect of the invention is a call response method for a vehicle as it depends from the first or the second aspect, wherein the call reception previous notification which appeals to the sense of smell is performed by generating smell which previously notifies a call reception.




According to the third aspect, the call reception previous notification which appeals to the sense of smell is performed by generating smell which previously notifies a call reception. Therefore, for example, even when a call including at least an image is received, with an elapse of the predetermined intervals after the call reception previous notification which does not appeal the sense of sight of a driver has been performed, the call reception main notification which appeals to the sense of sight of a driver is performed, so that a call response based upon a safety drive can be realized.




Furthermore, a fourth aspect of the invention is a call response method for a vehicle as it depends from one aspect among the first aspect to the third aspect, wherein the call reception previous notification which appeals to the sense of touch is performed by generating vibration which predicts a call reception.




According to the fourth aspect, the call reception previous notification which appeals to the sense of touch is performed by generating vibration which predicts a call reception. Therefore, for example, even when a call including at least an image is received, with an elapse of the predetermined intervals after the call reception previous notification which does not appeal the sense of sight of a driver has been performed, the call reception main notification which appeals to the sense of sight of a driver is performed, so that a call response based upon a safety drive can be realized.




In addition, a fifth aspect of the invention is a call response method for a vehicle as it depends from one aspect among the first aspect to the fourth aspect, wherein the vibration which previously notifies the call reception is given to at least one of a steering wheel and a driver's seat in the vehicle.




According to fifth aspect, the vibration which previously notifies the call reception is given to at least one of a steering wheel and a driver's seat in the vehicle. Therefore, for example, even when a call including at least an image is received, with an elapse of the predetermined intervals after the call reception previous notification which does not appeal the sense of sight of a driver has been performed, the call reception main notification which appeals to the sense of sight of a driver is performed, so that a call response based upon a safety drive can be realized.




Also, a sixth aspect of the invention is a call response method for a vehicle as it depends from one aspect among the first aspect to the fifth aspect, wherein the call which has been received in the vehicle from the another system is an interphone call including at least an image which has been received from a home interphone which has been provided on a home side.




According to the sixth aspect, the call which has been received from the another system is an interphone call including at least an image which has been received from a home interphone which has been provided on a home side. Therefore, for example, even when a call including at least an image is received, with an elapse of the predetermined intervals after the call reception previous notification which does not appeal the sense of sight of a driver has been performed, the call reception main notification which appeals to the sense of sight of a driver is performed, so that a call response based upon a safety drive can be realized.

11


for a vehicle will be explained in detail with reference to FIG.


4


.





FIG. 4

is a flow chart showing a series of operations/actions in the call response method for a vehicle according to the present invention.




As shown in

FIG. 4

, in Step S


11


, while the home interphone


65


is put in the absence mode where a message and an image of a visitor which has visited an absent home are transferred to the vehicle side, when a visitor pushes the call button of the home interphone


65


, the vehicle-mounted communication device


13


receives an interphone call including an image of the visitor and transfers the reception of the interphone call to the vehicle-mounted interphone


17


via the vehicle-mounted server


15


. Incidentally, when the vehicle side is called from a portable telephone or the like, the vehicle-mounted communication device


13


receives a call including an image of a calling person and transfers the reception of the call to the vehicle-mounted interphone


17


via the vehicle-mounted server


15


.




In Step S


12


, when the vehicle-mounted interphone


17


receives an interphone call including an image, a call reception previous notification for previously signaling the call reception is performed to appeal to one of the senses of hear, smell and touch except for the sense of sight or a combination of at least two of the three senses.




Herein, a plurality of examples of the call reception previous notification will be explained. First, the call reception previous notification for appealing to the sense of hear is performed by generating a sound or voice for previously signaling a call reception through the vehicle-mounted speaker, such as a chime sound generation for signaling a call reception, a sound or voice message “CALL HAS BEEN RECEIVED” or the like, or the like.




Also, the call reception previous notification for appealing to the sense of smell is performed by generating smell for previously signaling a call reception using the smell generator


29


.




Furthermore, the call reception previous notification for appealing to the sense of touch is performed by generating vibrations for previously signaling a call reception using the steering wheel vibrator


25


and/or the seat vibrator


27


. Incidentally, vibrations for previously signaling a call reception are imparted to at least one of the steering wheel and the driver's seat in the vehicle.




In Step S


13


, the vehicle-mounted server


15


maintains a state of a point of time when a call has been received, and it waits for a predetermined interval, for example, 5 seconds. The reason why the waiting period is set is because, if an image of a visitor or a calling person is instantaneously displayed without the waiting period, the eyes of a driver driving a vehicle are instantaneously attracted to the image. Namely, by setting the waiting period, the above situation is beforehand prevented from occurring, thereby serving to secure a safety driving or running of a vehicle.




In Step S


14


, the vehicle-mounted interphone


17


is performed by issuing a call reception main notification for presenting an image included in a call so as to appeal to the sense of sight of a driver in a vehicle. Specifically, the vehicle-mounted H/U


23


displays an image of a visitor near the entrance of the home and a written message “A VISITOR HAS COME. PLEASE PUSH PESPONSE BUTTON” on the display screen of the vehicle-mounted display


37


and generates a sound or voice guidance “A VISITOR HAS COME. PLEASE PUSH RESPONSE BUTTON”. At this time, the visitor monitor camera


59


at the home side photographs an image of the visitor at the home side in response to operation information relating to a photographing instruction from the vehicle side and the image which has been photographed is transferred to the vehicle side at predetermined intervals.




In Step S


15


, when a driver or a vehicle occupant performs a pushing operation on the communication button


41


illustrated in

FIG. 2

or


3


within a predetermined interval, for example, 10 seconds, it is assumed that he/she has an intention of communication, and the control routine advances to Step S


16


. On the other hand, when he/she does not perform a pushing operation on the communication button


41


or he/she performs a pushing operation on the rejection button


42


illustrated in

FIG. 2

or


3


within the predetermined, it is assumed that communication is rejected, and the control routine advances to Step S


18


.




In Step S


16


, the vehicle-mounted interphone


17


transmits the pushing operation on the communication button


41


to the vehicle-mounted server


15


via the vehicle-mounted H/U


23


so that the vehicle-mounted server


15


transmits an interphone ON command back to the vehicle-mounted H/U


23


. The vehicle-mounted H/U


23


, switches the operation mode from a waiting mode to a communication mode allowing communication while the driver or the occupant is watching the image of the visitor via the interphone. Thereby, the image of the visitor near the entrance at the home side and a message “COMMUNICATON IN PROGRESS” are displayed on the display screen of the vehicle-mounted display


37


. At this time, the visitor monitor camera


59


at the home side photographs an image of the visitor approaching the home side in response to operation signals regarding a photographing instruction from the vehicle side and updates the image which has been photographed at predetermined intervals, for example, each 3 seconds, to transmit the same to the vehicle side.




In Step S


17


, when a predetermined interval, for example 3 seconds, has been elapsed or the communication button


41


is pushed down again, it is assumed that the communication has been finished. Then, the vehicle-mounted server


15


transmits an interphone OFF command to the vehicle-mounted H/U


23


so that the vehicle mounted H/U


23


switches the operation mode of the vehicle-mounted interphone


17


to the communication mode to the waiting mode. At this time, a written message “COMMUNICATION FINISHED” is displayed on the display screen of the vehicle-mounted display


37


and a sound or voice guidance “COMMUNICATION FINISHED” is generated. Thus, a series of call response processing are terminated.




Meanwhile, In Step S


18


, when communication is rejected at the vehicle side, the vehicle-mounted server


15


causes the home side home interphone


65


to output a sound or voice guidance “CAN NOT RESPOND NOW, PLEASE RECORD MESSAGE” or the like, which requires a visitor to record an absence message. At this time, the visitor at the home side records a message according to the sound or voice guidance.




In Step S


19


, the vehicle-mounted server


15


receives the recorded absence data from the home interphone


65


at the home side and transmits the received recorded absence data to the vehicle-mounted interphone


17


.




In Step S


20


, the vehicle-mounted interphone


17


reproduces the recorded data at the vehicle side. After reproduction, a series of call response processings are terminated.
