Abstract:
1. A method of monitoring the speed of an automotive vehicle comprising: identifying, by a computer in operative communication with the automotive vehicle, an approaching road segment lying ahead of the vehicle; accessing a first speed profile of the approaching segment, the first speed profile generated by analyzing a statistical distribution of historical speed data collected from probe vehicles that have previously travelled over the approaching segment; identifying a baseline road segment over which the vehicle has previously travelled; accessing a second speed profile of the baseline road segment, the baseline road segment generated by calculating a statistical distribution of historical speed data from probe vehicles that have traveled over the baseline segment comparing, by the computer, a past speed of the vehicle over the baseline segment with the second speed profile to determine a speed differential; applying, by the computer, the speed differential to the first speed profile to establish a target vehicle speed over the approaching road segment; adjusting, by the computer, the target speed based on a desired relationship with at least one of the first speed profile and the second speed profile, the desired relationship being based upon at least one of a driver condition factor, a driving conditions factor, a vehicle condition factor, and a driver input factor; assessing, by the computer, whether the vehicle is likely to exceed the adjusted target speed over the approaching segment based, at least in part, on at least one measured vehicle dynamic property; and activating, by the computer, at least one vehicle system in response to the above assessment.
