The hybridization of the conventional thermal vehicles nowadays constitutes a paramount importance for car manufacturers,
facing the challenge of minimizing the consumption of the road transport. Although hybrid power train technologies did not
converge towards a single solution, series/parallel power trains with power-split electromechanical transmissions prove to
be the most promising hybrid technology. In fact, these power trains show maximum power train overall efficiency and maximum
fuel reduction in almost all driving conditions compared to the conventional and other hybrid power trains. This paper addresses
the model and design of the electro-mechanical configuration of one of the most effective HEV power trains: case study of
the 2nd generation Prius. It presents the simulation work of the overall operation of the Toyota Hybrid System (THS-II) of
the Prius, and explores not only its power-split eCVT innovative transmission system but also its overall supervision controller
for energy management. The kinematic and dynamic behaviors of the THS-II power train are explained based on the power-split
aspect of its transmission through a planetary gear train. Then, the possible regular driving functionalities that result
from its eCVT operation and the energy flow within its power train are outlined. A feed-forward dynamic model of the studied
power train is next proposed, supervised by a rule-based engineering intuition controller. The energy consumption of the THS-II
proposed model has been validated by comparing simulation results to published results on European, American and Japanese
regulatory driving cycles. 相似文献

Environmental improvement and energy issues are increasingly becoming more important as worldwide concerns. Natural gas is
a good alternative fuel that can help to improve these issues because of its large quantity and clean burning characteristics.
This paper provides the experimental performance results of a Bi-Fuel engine that uses Compressed Natural Gas as its Primary
fuel and gasoline as its secondary fuel. This engine is a modification of the basic 1.4-liter gasoline engine. Generally,
on the unmodified base engine, torque and power for CNG fuel are considerably lower than gasoline fuel. In this paper, the
influence of fuels on wall temperature, performance and emissions are investigated. 相似文献

Power Requirements for Vehicle Suspension Systems 总被引:1,自引:0,他引:1
D. Karnopp 《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》1992,21(1):65-71
This paper attempts to analyze the power requirements of a vehicle due solely to its suspension system, neglecting the important powers associated with air and rolling resistance. Power requirements for active and passive suspensions are compared using the simplest possible mathematical model. A mass in a gravity field moves at constant velocity over a surface and is supported by a point contact on the surface by a massless but otherwise arbitrary suspension system. It is shown that the average propulsive power required is equal to the average power lost in the suspension. In the limit cases of very stiff or very soft suspensions this power vanishes. Passive suspensions require no other power, but active suspensions may require significant extra power from the prime mover to generate the suspension forces. 相似文献
