Enabling alert messages in a vehicle
First Claim
1. A method comprising:
- receiving location data indicative of a location of a navigation device;
identifying, using a processor, a plurality of road segments based on the location data, wherein the plurality of road segments are an electronic horizon of the possible routes extending from a road segment including the location of the navigation device;
identifying, using the processor, one or more conditions along the plurality of road segments, wherein each condition is associated with a precautionary action;
ranking, using the processor, the one or more conditions based on a degree of severity of each of the one or more conditions;
andproviding an alert signal to the navigation device for each of the one or more conditions where alert signals of the one or more conditions with a higher rank are given precedence.

Abstract
A feature for a motor vehicle that takes precautionary actions in response to conditions on the road network in the vicinity ahead of the vehicle. The feature uses a data representation of the road network extending from the current vehicle position out to an extent. The data representation of the road network is used to identify conditions, if any, that warrant taking a precautionary action. The type of conditions about which actions are to be taken may be identified in a data file. A precautionary action is taken as the vehicle approaches the location of the condition. The precautionary action may be a message provided to the vehicle driver to alert the driver about the condition. Alternatively, the action may be a modification of the vehicle operation, such as slowing down or stopping the vehicle, speeding up the vehicle, changing direction, and so on.

11. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;receive location data indicative of a location of a navigation device; identify, using the at least one processor, a plurality of road segments extending from the location of the navigation device, wherein each of the one or more conditions along the plurality of road segments is associated with a precautionary action, and wherein a degree of severity is associated with the one or more conditions; identify, using the at least one processor, one or more conditions along the plurality of road segments; generate an alert signal for each of the one or more conditions; and provide, for each of the one or more conditions in an order of decreasing severity, the alert signal to be delivered to a driver by the navigation device. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method comprising:
-
receiving location data indicative of a location of a vehicle; identifying, using a processor, a plurality of road segments leading from the location of the vehicle based on the location data; identifying, using the processor, a plurality of hazards along the plurality of road segments, wherein each of the plurality of hazards along the plurality of road segments is associated with a precautionary action, assigning a degree of severity of each of the plurality of hazards; and providing an alert to the vehicle in response to the one or more hazards of the plurality of hazards in a decreasing order of severity based on the respective, relative severity of each identified hazard. - View Dependent Claims (19, 20)
