Claim 13:
14. An erratic vehicle detection and mitigation (EVDAM) system for a host vehicle, comprising:
at least one external sensor configured to collect sensor information on a calibratable sensor region surrounding the host vehicle; and
a module configured to:
process the sensor information from the at least one external sensor to detect: (i) the erratic vehicle within the calibratable sensor region surrounding the host vehicle and (ii) a position of the erratic vehicle relative to the host vehicle, and

implement a mitigating action including increasing a distance of the host vehicle form the erratic vehicle;
wherein the mitigating action includes:
determining the host vehicle is in a same lane behind the erratic vehicle;
determining a current speed of the host vehicle and a maximum posted speed limit;
calculating an overtaking speed to pass a target vehicle; and
including at least one of: (i) initiating a lane change overtaking routine when a sum of the current speed of the host vehicle and the calculated overtaking speed is less than the maximum posted speed limit, (ii) decelerating the host vehicle when the sum of the current speed of the host vehicle and the calculated overtaking speed is equal to or greater than the maximum posted speed limit, and (iii) changing lanes when the sum of the current speed of the host vehicle and the calculated overtaking speed is equal to or greater than the maximum posted speed limit;
wherein the calibratable region surrounding the host vehicle is defined between an inner sensor range and an outer sensor range, and
wherein the inner sensor range and the outer sensor range are calibrated with respect to a velocity of the host vehicle and detected environmental conditions, such that a confidence level of information gathered by external sensor is above a predetermine confidence level and provides sufficient time for the module to process the external sensor information in order to detect and mitigate the erratic vehicle.
