Abstract
A vehicle system for estimating a trailer size may include a plurality of sensors arranged on a vehicle and may be configured to detect objects external to the vehicle and provide trailer data indicative of a trailer location behind a vehicle and a memory configured to maintain a virtual grid including a plurality of cells. The system may also include a controller in communication with the sensors and memory and configured to determine, based on the trailer data received within a predefined amount of time, an occupancy frequency for each of the plurality of cells, the occupancy frequency being an incrementation of each time an object was detected within the respective cell; determine a threshold distribution based on the occupancy frequency of each cell; and determine a trailer size based on the cells having an occupancy frequency exceeding the threshold distribution.
