| description | 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 i |
