A method, system, and computer program product for vehicle presence indication. The method includes receiving a request including an announcement type at a first vehicle. The receiving is from a second vehicle via a mobile ad-hoc network that includes the first vehicle and the second vehicle. The announcement type is initiated at the first vehicle in response to receiving the request.

Vehicle presence indication

A tracking system adapted for use with communicatively coupled traveling host and remote vehicles, includes a locator device configured to determine sets of current position, and trail coordinates for each of the vehicles. The preferred system further includes sensors operable to determine a condition value for each vehicle at each of said set of coordinates, and a controller configured to determine a congruent path between the vehicles, and a congruent path divergence by the host vehicle, and cause the transmission of an alert of the divergence from the host vehicle to the remote vehicle using vehicle-to-vehicle communication.

System for and method of determining a host vehicle lane change

A method for monitoring vehicle speed is provided. The method includes receiving a current speed of a vehicle and a current speed limit associated with a current location of the vehicle. A current speed range is calculated by comparing the current speed of the vehicle to the current speed limit. Operator alert preferences including a caution range and a warning range are accessed. An alert responsive to the current speed range and to the operator alert preferences is communicated to the operator of the vehicle. The alert includes one or more caution attributes when the current speed range of the vehicle is within the caution range. The alert includes one or more warning attributes when the current speed range of the vehicle is within the warning range. The alert includes one or more at speed attributes when the current speed range of the vehicle is not within the caution range or the warning range.
