Methods and systems are provided for a vehicle towing a trailer. In one embodiment, a method includes: receiving, by a processor, sensor data from one or more sensors of the vehicle; estimating, by a processor, a steering torque value based on the sensor data; estimating, by the processor, a steering angle value based on the sensor data; determining, by the processor, a trailer tongue value based on the steering torque value and the steering angle value; and generating, by the processor, a control signal to control the vehicle based on the trailer tongue value.

Methods and systems are provided for a vehicle. In one embodiment, a method includes: initiating, by a processor, steering excitation according to a pattern while the vehicle is stationary; learning, by the processor, a load associated with a front axle of the vehicle based on the steering excitation; translating, by the processor, the load associated with the front axle of the vehicle to a load associated with a tongue of a trailer, and generating, by the processor, a trailer tongue load value based on the load associated with the tongue of the trailer.
