The application discloses a driving scene understanding method and device, and a trajectory planning method and device. The driving scene understanding method comprises the following steps of identifying stress driving behaviors from driving behaviors of human drivers; determining the identified types of stress driving behaviors; determining target objects corresponding to various stress driving behaviors according to the stress driving behaviors, the types of the stress driving behaviors and driving scene information corresponding to the stress driving behaviors; and completing the driving scene understanding according to the target objects. The driving scene understanding method and device and the trajectory planning method and device have the beneficial effects that the concept of stress is introduced during scene understanding, so that in the process of driving scene understanding, based on the effective learning of human drivers on the control of driving equipment, stress drivingbehaviors are specificall
