DETERMINATION METHOD AND DETERMINATION DEVICE FOR VEHICLE TRAFFIC EFFICIENCY, AND VEHICLE

The present disclosure discloses a determination method and a determination device for vehicle traffic efficiency, and a vehicle, and relates to the technical field of intelligent driving. The method includes: determining obstacle vehicles in lanes corresponding to a traveling vehicle, the obstacle vehicles including a same-lane leading vehicle and a different-lane leading vehicle of the traveling vehicle; determining a vehicle block cost parameter based on a first velocity of the traveling vehicle and a second velocity of the same-lane leading vehicle, and obtaining an obstacle block cost parameter of the different-lane leading vehicle; and determining lane traffic efficiency based on the vehicle block cost parameter, the obstacle block cost parameter, and a block weight coefficient, so as to select, based on the lane traffic efficiency, a lane for vehicle lane changing, the lane traffic efficiency representing an expected smooth traffic condition when the traveling vehicle enters a lane. According to the present disclosure, stability and safety requirements of determination of a vehicle lane change intention can be met, and accuracy of lane change planning is significantly improved.
