1. A vehicle system for notifying a driver of a vehicle that a trailer brake gain of a trailer hitched to the vehicle should be adjusted, the vehicle system comprising:
one or more sensors configured to sense parameters of the vehicle; and
a control module in communication with the one or more sensors, the control module configured to:
estimate a vehicle parameter and a trailer parameter of the trailer hitched to the vehicle;
receive one or more vehicle parameters from the one or more sensors;
calculate an actual braking utilization factor for the vehicle based on the one or more received vehicle parameters and the estimated vehicle parameter;
calculate an optimum braking utilization factor for the vehicle based on the estimated vehicle parameter and the estimated trailer parameter;
compare the optimum braking utilization factor and the actual braking utilization factor; and
in response to a difference between the optimum braking utilization factor and the actual braking utilization factor being greater than a defined threshold, generate an alert signal to notify the driver of the vehicle that the trailer brake gain for the trailer hitched to the vehicle should be adjusted.
