1. A vehicle, comprising:
a rear door;
at least one sensor component proximate to the rear door;
an alert system;
a memory in which program instructions are stored; and
a processor operably connected to the alert system, the at least one sensor component, and the memory, the processor configured to execute the program instructions to
detect an object within a detection zone of the at least one sensor component relative to the rear door,
activate the alert system in response to the object being within a predefined protection zone of the detection zone when the rear door is not moving and unlatched,
establish a first location of the object at a first time based upon a first set of relative signal strength levels detected by the at least one sensor component;
establish a second location of object at a second time based upon a second set of relative signal strength levels detected by the at least one sensor component; and
determine at least one of a speed and direction of movement of the object based on the first location, the second location, and a difference between the first time and the second time, wherein the processor is further configured to
execute the program instructions to activate the alert system in response to determining that an unsafe condition exists based upon at least one of the speed and direction of movement of the object, and
define the predefined protection zone based upon at least one of the speed and direction of movement of the object.
