This paper compares and assesses fuel consumption models, cost functions, and solution methods, as they all have an influence on the resulting profile and associated fuel savings of an eco-cruise control system for passenger vehicles. An eco-cruise control system uses road topographical data obtained from a high-resolution digital map to control the vehicle velocity to optimize its fuel consumption. The optimal velocity profile is the result of an optimal control problem.
► We compare methods to calculate the optimal velocity profile over hilly roads. ► A simple quadratic power-based quasistatic fuel consumption model is appropriate. ► An indirect time constraint should be added to the cost function. ► Eco-cruise control can save about 5% of fuel compared to conventional cruise control.
