STABILIZED DIRECTIONAL CONTROL SYSTEMS AND METHODS
First Claim
1. A system comprising:
- a logic device configured to receive one or more sensor signals and generate one or more controller signals to provide directional control for a vehicle, wherein the logic device is adapted to;
receive a steering angle and a yaw rate of the vehicle, wherein the steering angle is based, at least in part, on a steering demand;
determine a nominal vehicle steering rate based, at least in part, on the steering angle; and
determine a nominal vehicle feedback signal based, at least in part, on a combination of the nominal vehicle steering rate and the yaw rate, wherein the nominal vehicle feedback signal is provided to adjust the steering demand.

Abstract
Techniques are disclosed for systems and methods to provide stabilized directional control for a vehicle. A directional control system for an embodiment may include a logic device adapted to receive directional data about a vehicle and determine nominal vehicle feedback from the directional data. The nominal vehicle feedback may be used to adjust a directional control signal provided to an actuator of a vehicle. The directional control signal may be limited to a value below an actuator rate limit before a directional control signal is adjusted by the nominal vehicle feedback. A directional control system may include a logic device, a memory, one or more sensors, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other modules of a vehicle.
