Vehicle lane changing and obstacle avoiding method and vehicle

The invention relates to a vehicle lane changing and obstacle avoiding method and a vehicle. The method comprises the steps that when it is monitored that a vehicle has a lane changing demand, the lane changing interval of adjacent lanes is obtained according to the vehicle position on the adjacent lanes and the obstacle position on the current lane where the vehicle is located; according to the position of the vehicle in front of each lane changing interval and/or the position of the vehicle behind each lane changing interval, corresponding lane changing areas are determined; according to the speed information and the vehicle positions of the own vehicle and the vehicles on the adjacent lanes, speed planning curves of the own vehicle arriving at the corresponding lane changing areas are obtained respectively; and screening the lane changing intervals according to a preset screening rule, and determining a corresponding target lane changing interval in the lane changing intervals, so that the vehicle changes
