Vehicle control system for traversing obstacles
First Claim
1. A vehicle control system, comprising:
- an active steering system including a steerable wheel defining a steering angle and a steering wheel defining a driver input control angle, said active steering system further including a coupler component, an actuator component, a controller component, and a sensor component, said components operably interconnected such that said controller component can selectively vary said steering angle relative to said driver input control angle, said steering angle defining a desired path;
said sensor component configured to detect at least a first vehicle operating parameter indicating that the vehicle is off road, and to detect at least a second vehicle operating parameter indicating that the vehicle has encountered an object preventing the vehicle from traveling along said desired path;
said controller component adapted to oscillate said steerable wheel when said sensor component detects that the vehicle is off road and has encountered an object preventing the vehicle from traveling along said desired path.

Abstract
A vehicle control system includes an active steering system having a steerable wheel defining a steering angle and a steering wheel defining an input control angle. The steering system further includes a coupler component, a actuator component, a controller component and a sensory component. The components are interconnected such that the controller component can selectively vary the steering angle relative to the input control angle. The steering angle defines a desired path. The sensor component detects a first vehicle operating parameter indicating that the vehicle is off road and a second vehicle operating parameter indicating that the vehicle has encountered an object preventing the vehicle from traveling along the desired vehicle path. The controller component is adapted to oscillate the steerable wheel when the sensor component detects that the vehicle is off road and has encountered an object preventing the vehicle from traveling along the desired path.
