Systems and methods for autonomous control of a vehicle

Systems and methods for autonomous control of a vehicle include interruptible, behaviour-based, and selective control. Autonomous control 100 is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events 116 that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay 126, or prevented 128. Systems and methods for processing safety signals and/or tracking terrain features are also utilized by an autonomous vehicle.
