在一个实施方式中,自动驾驶车辆(ADV)在用于多个驾驶的路线上自动驾驶。对于多个驾驶中的每个驾驶,以时间间隔记录ADV沿路线的位置,从而产生一个或多个记录位置。每个记录位置均指示ADV在相应时间间隔在路线上的位置。基于所记录的驾驶数据,确定在每个时间间隔处的一个或多个平均位置,以及完成路线的平均总驾驶时间。当ADV在该路线上驾驶时,基于a)平均总驾驶时间和b)与ADV所处的平均位置相对应的时间间隔之间的差异,估计完成该路线所剩的时间量。
In one embodiment, an autonomous driving vehicle (ADV) drives autonomously on a route for a plurality of drives. For each drive of the plurality of drives, a position of the ADV is recorded at time intervals along the route, resulting in one or more recorded positions. Each of the recorded positions indicates the position of the ADV on the route at a corresponding time interval. One or more average positions at each time interval is determined, as well as an average total drive time to complete the route, based on the recorded drive data. An amount of time left to complete the route is estimated, when the ADV drives on the route, based on difference between a) the average total drive time, and b) the time interval corresponding to the average position that the ADV is located at.
