Methods and systems for optimizing performance of vehicle guidance systems
First Claim
1. A method for optimizing performance of a guidance system for a vehicle, the method comprising:
- receiving data representative of a weight associated with a periodically changing payload towed by the vehicle, an overall possible weight change of the payload being equivalent to a weight of the vehicle; and
setting or adjusting a steering parameter of the guidance system at least partially based on the weight such that the guidance system steers the vehicle in a manner that compensates for the weight,wherein the receiving and setting steps are automatically performed by a computing device of the guidance system.

Abstract
A vehicle guidance system includes a location determining component for determining locations of the vehicle; a weight sensor for sensing a weight associated with the vehicle; a steering actuator for steering at least one wheel of the vehicle; and a computing device in communication with the location determining component, the weight sensor, and the steering actuator. The computing device receives cartographic data representative of a desired path for the vehicle, receives location information from the location determining component, controls operation of the steering actuator in order to guide the vehicle along the desired path, and adjusts a steering parameter at least partially based on the weight sensed by the weight sensor.
