Abstract
Systems and methods for determining force direction and magnitude acting on a trailer hitch are disclosed. An example vehicle includes two magnetoelastic pins, having respective magnetic fields, configured to couple a trailer hitch receiver to a vehicle chassis. The vehicle also includes a plurality of sensors corresponding to the two magnetoelastic pins, configured to detect changes in the respective magnetic fields. And the vehicle further includes a processor configured to determine a magnitude and direction of a force acting on the trailer hitch receiver based on data from the plurality of sensors.
