Abstract: A control system for road building machines, particularly pavers, that automatically transitions the machine between operational states using closed-loop feedback control to achieve consistent paving joints. The system comprises a speed input mechanism for setting target speeds, a launch control input for initiating transitions, a controller executing closed-loop feedback control algorithms, and sensors monitoring machine speed, position, velocity, acceleration, and electrical current. The controller automatically generates controlled acceleration profiles using real-time sensor feedback to transition the machine from a first operational state to a second operational state, where each state may be either stationary or moving at a specified speed. This enables consistent transitions when starting from rest, accelerating to higher speeds, decelerating to lower speeds, or stopping, thereby eliminating variability in joint formation caused by manual operation.
