Optimal velocity car following model
WebOct 15, 2015 · A new optimal velocity function was also proposed with respect to the empirical data as: V ( h) = V 1 + V 2 tanh [ C 1 ( h − l c) − C 2], where l c is the length of the vehicles taken as 5 m in simulations. The resulting optimal parameter values are V 1 = 6.75 m / s, V 2 = 7.91 m / s, C 1 = 0.13 m − 1, and C 2 = 1.57. 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 …
