N2 - In this paper, we establish a mathematical framework that allows us to optimize the speed profile and select the optimal gears for heavy-duty vehicles. The key idea is to solve the analogous boundary value problem analytically for a simple scenario (linear damped system with quadratic elevation profile) and use this result to initialize a numerical continuation algorithm. Then the numerical algorithm can be used to gradually introduce nonlinearities (air resistance, engine saturation), implement databased elevation profiles, and incorporate external perturbations (wind, traffic). This app roach enables real-time optimization in dynamic traffic conditions, therefore may be implemented on board.
