Model-based sensitivity analysis of the look-ahead cruise control

摘要

The paper focuses on the analysis of the look-ahead cruise control strategy. The control system designs a reference speed profile for road vehicles considering the road inclinations, speed limits and traveling time. The design of the speed profile leads to a quadratic optimization problem, which depends on several parameters. The most important parameters are the mass of the vehicle, the initial conditions, the number of sampling points along the prediction horizon, the road length between the sampling points and the weighting between the performances. In the paper the effects of parameter variations on the optimal speed profile are analyzed through various simulation scenarios.
