Positionable vibratory roller

A method for a controlled grading operation of a vehicle within a work site, the vehicle having a tool assembly movable relative to the vehicle, a controller configured to control the tool assembly, and a position tracking system, the tool assembly including a roller and a blade assembly movable relative to the roller, the method comprising:

• receiving, by the controller, an engineering plan associated with the work site;
• identifying, by the position tracking system, a first position of the work vehicle within the work site using a position signal received from a global navigation satellite system;
• identifying, by the controller, a target blade elevation for the blade based on the engineering plan and the identified position of the work vehicle within the work site;
• transmitting a lift actuator control signal from the controller to adjust the blade elevation;
• and
• adjusting the elevation of the blade assembly relative to the roller so that a measured blade assembly position approaches the target blade assembly position.

A work vehicle comprising:

• a tool frame;
• a compactor mounted to the tool frame;
• a blade assembly mounted to the tool frame;
• a lift actuator extending between the blade assembly and the tool frame and configured to raise and lower the blade assembly relative to the tool frame;
• a tilt actuator extending between the tool frame and the vehicle and configured to tilt the tool frame relative to the vehicle;
• a controller configured to receive a control signal and to transmit a command signal to control the lift actuator and the tilt actuator in response to the command signal;
• and
• a position sensor configured to measure the position of the work vehicle within a work site,
• wherein the control signal is generated according to the position of the work vehicle within the work site and a program correlating a target blade elevation and a target tool assembly tilt to the position of the work vehicle within the work site, and the command signal drives the lift actuator and the tilt actuator such that a measured blade assembly elevation and a measured tool assembly tilt approach the target blade elevation and the target tool assembly tilt correlated to the position of the work vehicle within the work site.
