The invention discloses an automatic emergency braking function triggering opportunity correction method considering steering constraint, and belongs to the technical field of advanced driving assistance systems and unmanned systems, and the method comprises the steps that a sensor collects motion parameters of a vehicle and a target, calculates longitudinal collision time, calculates steering time of the vehicle, and collects current scene information; and determining a special scene correction factor, calculating a trigger condition, and issuing a braking instruction. According to the method, the accuracy of the AEB triggering condition is improved by calculating the steering time, so that the reasonability of the automatic emergency braking triggering opportunity is ensured, and large-scale mass production application of the automatic emergency braking function is realized; by determining the correction factor of the special scene in the vehicle driving process and fully considering the risk scene in the vehicle driving process, the accuracy of the triggering condition is improved, the possibility that the vehicle has an accident is reduced, and safe driving is ensured.
