Abstract
A vehicle may include a passenger compartment, one or more vehicle controls in the passenger compartment, a user interface in the passenger compartment, and a trailer hitch towards the rear end of the vehicle. The vehicle may include an accelerometer and a vehicle control unit (VCU). The accelerometer may output a signal in response to a change in pitch of the vehicle as a trailer is attached to the vehicle at the trailer hitch. The VCU may have a memory device and a processing device. The processing device may: determine the change in the pitch of the vehicle; determine a tongue weight of the trailer based on the change in the pitch; compare the tongue weight to a threshold tongue weight; and, in response to the tongue weight being greater than the threshold tongue weight, output a warning indicator via the vehicle's user interface.
