The invention discloses a variable-weight adaptive cruise control method, system and equipment considering curve cut-in, and relates to the technical field of vehicle control. Acquiring image data of a road scene in front of the host vehicle; inputting the image data into a classifier to obtain a driving condition of the main vehicle; constructing a cut-in recognizer based on an LSTM network according to the driving condition of the main vehicle and the driving information of the vehicles on the adjacent lanes, and determining the driving condition of the vehicles on the adjacent lanes; constructing a dynamic car following model containing the variable time headway; building a car-following cruise control system prediction model according to the dynamic car-following model; comprehensively considering the fuel economy, the vehicle-following safety and the riding comfort of the vehicle, and determining a cost function of the prediction model of the vehicle-following cruise control system; and dynamically adjusting the weight coefficient of the cost function of the prediction model of the vehicle-following cruise control system according to the driving conditions of the vehicles on the adjacent lanes to control the driving of the main vehicle. The self-adaptive cruise control system can realize self-adaptive cruise control of straight movement and curves.
