The invention relates to an automatic emergency braking decision-making method based on multisensor fusion data. The automatic emergency braking decision-making method comprises the following steps: sensing an obstacle in front of a vehicle; based on the multisensor fusion data, carrying out secondary screening on the obstacle to obtain an effective obstacle; wherein the effective obstacle is determined by an automatic emergency braking system; determining the minimum collision distance between the vehicle and the effective obstacle; and based on the minimum collision distance, generating thedecision-making information of automatic emergency braking. According to the automatic emergency braking decision-making method, the possibility of a reporting failure is reduced through the multisensor fusion technology, and the minimum collision distance is relevant to the state of the automatic emergency braking system, so that premature or too-late intervention and premature or too-late release of automatic emergency braking are avoided, and the subjective and objective feelings of a driver are taken into consideration; and the automatic emergency braking decision-making information is generated based on the minimum collision distance to reduce collision probability and severity.
