Development of optimization algorithm for green drive on roads with continuous curves

Abstract

This paper presents an optimal strategy of Curve Speed Assistance (CSA) for continuous curves of the road. For the classification of the speed limits on the straight and curved lines on roads, the speed limit before entering the curve and within the curve can be divided. Previous studies have shown that the speed limit within the curve is calculated by the turning radius and the safe speed for negotiating a curve depending on the vehicle dynamics, road characteristics and driver performance index. Before entering the curve, the speed limit is considered as the solution for optimization problem between the fuel consumption and travel time on continuous curves. Based on the driving scenarios, the optimization algorithm is to verify the optimal speed limits on the trade-off relationship between the fuel consumption and travel time. As the results of the simulation, the optimization algorithms are validated by vehicle simulation using MSC's CarSim® and Matlab/Simulink ®.
