Optimal velocity car following model
WebJan 14, 2024 · The optimal velocity (OV) model that was initiated by Bando et al. [ 5] is a notable example of the engineering-based car-following model [ 6 ]. It assumes that each vehicle has an optimal car-following speed (CFS) dependent on spacing between the lead and lag vehicles. WebA hybrid vehicle is a vehicle with two or more power sources. We propose a hybrid system in which the engine torque converted by the transmission is combined with an electric motor torque. The proposed system reduces transmission because engine torque only acts during transmission. Furthermore, the proposed hybrid system’s simple structure uses …
