Abstract-This paper develops an indirect optimal control methodology to achieve green driving optimisation for series hybrid electric vehicles. Starting from a given vehicle mission, specified in terms of a road journey that has to be completed in a given amount of time, the power sharing among the powertrain sources and the vehicle speed profile along the journey are optimised and found. The scheme combines parametric modelling of the vehicle and powertrain together with computationally efficient optimal control software to provide an optimization strategy that works in real-time. Simulation results that demonstrate the success of the method and provide further insight into efficient driving, are presented.

“…In previous research, the fastest lap problem has been treated as simply involving optimization, [4][5][6][7][8][9][10][11][12][13][14] and, although successful outcomes have been achieved, particularly by Gerdts et al in their recent work, the necessary computations have been both complex and lengthy. In that prior work, the path to be followed by the vehicle was part of the optimization problem.…”

The paper is concerned with modelling car drivers. The context of the work presented is explained. Then, previous research on the application of optimal linear preview control theory to driving road vehicles with only modest excursions from a straight-running equilibrium state is extended into the general large-lateral-motion arena. Optimal controls are found for steadycornering trim states of an exemplary car at a given speed as a function of cornering effort, up to the practical limit. The manner in which the optimal controls change as the cornering vigour changes is discussed. Simulations of the virtual driver-controlled car are shown to demonstrate the closed-loop system following lateral path demands and the advantages of employing gain-scheduled adaptive control over a fixed control scheme are demonstrated.

“…A linear quadratic preview algorithm has been used to compute the solution. Motorcycles performance also have been studied with optimal control simulations, and the first example can be found in [Cossalter 1999]. In such work a simple bike model composed of a single body is used to simulate the optimal manoeuvre on the Lucco-Poggio Secco curves (Mugello track).…”

This work aims to study which level of detail should be preserved in the multibody modelling of a racing car in order to obtain reliable results without excessive model complexity. Three multibody models have been developed and compared through optimal control simulations. The models differ from each other for the order of dynamics comprised: starting from a 14 degrees of freedom (dof) car which includes chassis and wheels motion, a 10 dof model model is obtained by neglecting the wheels hop dynamics, finally a 7 dof model is derived by completely eliminating the suspension motion. Optimal control problem simulations, including parametric analyses varying the center of mass position and suspensions stiffness, have been executed on a full lap on the International circuit of Adria. Simulations results show that the 10 dof model gives almost the same results of the 14 dof one, while significantly reducing the computing time. On the contrary, the basic 7 dof model highlights remarkable differences in both the parametric analysis, suggesting the dynamics has been over-simplified.
