The invention discloses a threshold determination method and device for an ACC function. The method comprises the steps of obtaining target input operation and target sensing operation of a vehicle and the number of vehicles on an adjacent lane; then based on a pre-constructed driving scene model, according to the target input operation, obtaining first prediction probability distribution used for representing the overtaking intention of a driver; based on a pre-constructed vehicle situation perception model, according to the target perception operation, obtaining second prediction probability distribution used for representing the relative motion trend of the vehicle; calculating a threshold response operator according to the first prediction probability distribution, the second prediction probability distribution and the number of vehicles on adjacent lanes; and finally, adjusting the calibration threshold in the ACC according to the threshold response operator. Therefore, in the target scene, the driving intention of the driver is represented in the form of probability, so that the calibration threshold value of the ACC function is dynamically adjusted, and the calibration threshold value is continuous based on the actual situation.
