SYSTEM FOR DETECTING MOVING OBJECTS

A computer that includes a processor and a memory, the memory including instructions executable by the processor to determine a location and a trajectory of a moving object with respect to a stationary vehicle based on one or more first stationary vehicle sensors. A threat level can be determined based on the location and the trajectory of the moving object, and a control barrier function. Based on the threat level, the stationary vehicle can be operated to move the stationary vehicle to reduce a probability of impact between the stationary vehicle and the moving object.
