The present disclosure relates to a method performed by an overtaking estimating system (1) for estimation of a minimum overtaking speed of a vehicle. The overtaking estimating system determines (1001) in view of a host vehicle (2) a remaining distance (Dremaining) of an overtaking lane (42) contiguous to a driving lane (41) of the host vehicle. The overtaking estimating system further determines (1002) a delta distance (Ddelta) between the host vehicle and a preceding vehicle (7) positioned in the host vehicle driving lane. Moreover, the overtaking estimating vehicle determines (1003) a delta time for the host vehicle to reach the preceding vehicle. The overtaking estimating system further determines (1004) - based on the delta distance, the delta time and a determined host vehicle speed - a speed of the preceding vehicle. Furthermore, the overtaking estimating system determines (1005) - based on the remaining distance, the delta distance, the preceding vehicle speed, and an overtaking-affecting parameter - a minimum overtaking speed of the host vehicle for overtaking the preceding vehicle in the remaining distance of the overtaking lane.

    本申请涉及车辆的最小超车速度的估计。本公开涉及由超车估计系统(1)执行的用于估计车辆的最小超车速度的方法。超车估计系统基于本车辆(2)确定(1001)与本车辆的行驶车道(41)相邻的超车车道(42)的剩余距离(D剩余)。超车估计系统还确定(1002)本车辆和位于本车辆的行驶车道上的在前车辆(7)之间的增量距离(D增量)。此外,超车估计车辆确定(1003)本车辆到达在前车辆的增量时间。超车估计系统还基于增量距离、增量时间和确定的本车辆的速度来确定(1004)在前车辆的速度。此外,超车估计系统基于剩余距离、增量距离、在前车辆的速度和超车影响参数,来确定(1005)本车辆在超车车道的剩余距离内超车在前车辆的最小超车速度。
