Dynamic Traffic Announcement
A traffic announcement system for a motor vehicle utilizes a vehicular navigation system covering a geographical area, a receiver that receives traffic announcement signals, an in-vehicle audio system for presenting to a driver of the vehicle the received traffic announcements, and a controller linked to the navigation system and to the receiver. Via the controller the driver of the vehicle can selectively suppress the presentation of at least some traffic announcements. The controller includes a user input by which the driver identifies particular routes or localities within the geographical area covered by the navigation system for which traffic announcements are to be selectively suppressed. The controller then automatically suppresses the traffic announcements when the vehicle is on the identified routes or within the identified localities. The driver can also input selected time ranges when traffic announcements are to be suppressed.
1 . A traffic announcement system for a motor vehicle, the system comprising:
a receiver for receiving traffic announcement signals;
an in-vehicle audio system for presenting to a driver of the vehicle the received traffic announcements; and
a controller, linked to the receiver, by which a user selectively suppresses the presentation of at least some traffic announcements, wherein the controller comprises a user input by which the user identifies one or more particular times of day during which the traffic announcements are to be selectively suppressed, the controller then automatically suppressing the traffic announcements during the user identified times.
2 . A traffic announcement system as claimed in claim 1 , in which the user input of the controller accepts input by the user to assign one of a plurality of weightings to particular time of day, as well as input by the user to set a threshold related to the weightings so that the controller then automatically suppresses the traffic announcements at a particular time of day only if the weighting for the time of day is above the threshold.
3 . A traffic announcement system as claimed in claim 1 , further comprising:
a vehicular navigation system covering a geographical area, the controller being linked to the navigation system;
wherein the user input of the controller accepts input by the user to identify particular routes or localities within the geographical area covered by the navigation system for which the traffic announcements are to be selectively suppressed, the controller then automatically suppressing the traffic announcements when the vehicle is on the identified routes or within the identified localities during the user identified times.
4 . A traffic announcement system for a motor vehicle, the system comprising:
a vehicular navigation system covering a geographical area;
a receiver for receiving traffic announcement signals;
an in-vehicle audio system for presenting to a driver of the vehicle the received traffic announcements; and
a controller, linked to the navigation system and to the receiver, by which a user selectively suppress presentation of at least some traffic announcements, wherein the controller comprises a user input by which the user identifies particular routes or localities within the geographical area covered by the navigation system for which the traffic announcements are to be selectively suppressed, the controller then automatically suppressing the traffic announcements when the vehicle is on the identified routes or within the identified localities.
5 . A traffic announcement system as claimed in claim 4 , in which the user identified localities include an area around a driving destination.
6 . A traffic announcement system as claimed in claim 4 , wherein the user input of the controller accepts input by the user to identify one or more particular times of day during which the traffic announcements are to be selectively suppressed.
7 . A traffic announcement system as claimed in claim 6 , in which the selective suppression of traffic announcements requires that the vehicle is on the identified routes or within the identified localities during the identified times of day.
8 . A traffic announcement system as claimed in claim 3 , wherein the user input of the controller accepts input by the user to identify a particular driving direction along the identified routes, for which the traffic announcements are to be selectively suppressed, the controller then automatically suppressing the traffic announcements when the vehicle is on the identified routes and moving in the identified particular driving directions.
9 . A traffic announcement system as claimed in claim 3 , wherein the controller further comprises:
an adaptive controller linked to the vehicular navigation system and arranged to automatically identify from driving patterns the most common routes and destinations used by the driver;
wherein the user input of the controller accepts user input to control the automatic suppression of said traffic announcements for the most common routes and destinations.
10 . A traffic announcement system as claimed in claim 3 , wherein the user input of the controller accepts user input by which the user assigns one of a plurality of weightings to particular routes or localities within the geographical area, as well as user input by which the user sets a threshold related to the weightings so that the controller then automatically suppresses the traffic announcements when the vehicle is on the weight assigned routes or within the weight assigned localities only if the weighting for the weight assigned routes or within the weight assigned localities is above the set threshold.
11 . A traffic announcement system as claimed in claim 3 , further comprising a user control input selected from the group consisting of:
a user control input connected to the controller to accept input from the user to turn off all traffic announcements;
a user control input connected to the controller to accept input from the user to turn on all traffic announcements; and
a user control input connected to the controller to accept input from the user to enable said selective suppression of traffic announcements.
12 . A method of controlling the presentation of radio traffic announcements to the driver of a motor vehicle, the vehicle comprising an electronic timekeeping device, a radio transmission receiver, an in-vehicle audio system, and a controller linked to the electronic timekeeping device and to the receiver; the method comprising the steps of:
receiving traffic announcement signals via the radio receiver;
inputting into the controller particular times of day for which the traffic announcements are to be selectively suppressed;
generating an actual time of day using the electronic timekeeping device;
comparing the particular times of day with the actual time of day; and
suppressing automatically, using the controller, the presentation of the traffic announcements by the audio system when the actual time of day corresponds with the particular times of day.
13 . A method of controlling the presentation of radio traffic announcements to the driver of a motor vehicle, the vehicle comprising a vehicular navigation system covering a geographical area, a radio transmission receiver, an in-vehicle audio system, and a controller linked to the navigation system and to the receiver; the method comprising the steps of:
receiving traffic announcement signals using the radio receiver;
inputting into the controller particular routes or localities within the geographical area covered by the navigation system for which the traffic announcements are to be selectively suppressed; and
suppressing automatically, using the controller, the presentation of the traffic announcements by the audio system when the vehicle is on the inputted routes or within the inputted localities.
