1. A method for determining traffic stream information, comprising:
grouping each of target vehicles based on motion information of a host vehicle and state information of one or more of the target vehicles to obtain grouping information;
determining a fitting weight for each of the target vehicles based on the state information and the grouping information for each of the target vehicles; and
generating, by the fitting, one or more pieces of current traffic stream information based on the motion information of the host vehicle, the state information of each of the target vehicles, the fitting weights and the grouping information of each of the target vehicles;
wherein, each group corresponds to a traffic stream; the generating, by the fitting, one or more pieces of current traffic stream information comprises:
for one of the groups:
selecting a fit method based on the number of target vehicles in the group and the longitudinal distribution distance of all target vehicles in the group;
generating, by fitting, current traffic stream information corresponding to the group based on the selected fit method and by using the motion information of the host vehicle, the state information of each of the target vehicles in the group and the fitting weight of each of the target vehicles in the group; and
performing lateral control of the host vehicle based on current traffic stream information.
