GAP SELECTION METHOD AND SYSTEM

摘要

A gap selection method performed by a gap selection system for a vehicle. The vehicle travels on a road having a first lane and a second lane adjacent to the first. The vehicle travels in the first lane, a first surrounding vehicle travels in the second lane, a second surrounding vehicle travels in the second lane ahead of the first surrounding vehicle with a first gap between the first and second surrounding vehicles. The method includes determining a first minimum safety margin between the first surrounding vehicle and the vehicle, determining a second minimum safety margin between the second surrounding vehicle and the vehicle, evaluating the first gap by determining a minimum limit for a longitudinal position of the vehicle, determining a maximum limit for a longitudinal position of the vehicle, and determining a lane change appropriateness value of the first gap utilizing the minimum limit and the maximum limit.

1. A gap selection method performed by a gap selection system for a vehicle travelling on a road comprising a first lane and a second lane adjacent to the first lane, the vehicle travelling in the first lane, a first surrounding vehicle travelling in the second lane, a second surrounding vehicle travelling in the second lane ahead of the first surrounding vehicle with a first gap between the first and second surrounding vehicles, the method comprising:
determining a first minimum safety margin as a longitudinal distance between the first surrounding vehicle and the vehicle; determining a second minimum safety margin as a longitudinal distance between the second surrounding vehicle and the vehicle; evaluating the first gap by determining a minimum limit for a longitudinal position of the vehicle utilizing dynamic longitudinal position information of the vehicle and a predicted position of the first surrounding vehicle considering the first minimum safety margin; determining a maximum limit for a longitudinal position of the vehicle utilizing dynamic longitudinal position information of the vehicle and a predicted position of the second surrounding vehicle considering the second minimum safety margin; and determining a lane change appropriateness value of the first gap utilizing the minimum limit and the maximum limit for a longitudinal position of the vehicle.
