Abstract


Tractor has a low speed , no climbing and long idle time in the operation of the container terminal , so the car engine work in the inefficient zone , resulting in fuel utilization is low, higher emissions . In this paper, the characteristics of the special tractor operating conditions the hybrid drive system analysis and design , by optimizing to reduce vehicle emissions and improve fuel efficiency and reduce manufacturing costs . The main contents are as follows : ( 1 ) hybrid commercial vehicles on the world container trade increased demand for the Terminal Tractor profiles obtained adapted the feasibility and importance of the hybrid terminal tractors . Hybrid vehicles matching method and the need to address the key technology in the vehicle development process . ( 2) for terminal tractors running characteristics , by analyzing and comparing strings, and the structure of the advantages and disadvantages of hybrid cars and hybrid , with reference to foreign hybrid state of technology , combined with the performance requirements of the Terminal Tractor , proposed in this article the study of the structure of the drive system of hybrid terminal tractors . (3) the best vehicle fuel consumption and emissions as the control target, to limit the working range of the engine is in the high efficiency range , for this formulation of the control strategy , the preparation of a block diagram of the control algorithm to lay the foundation for the realization of the simulation . ( 4 ) on the parameter selection and matching powertrain detailed analysis and research , vehicle performance simulation analysis of the text the series hybrid terminal tractors design and use of a hybrid electric vehicle simulation software ADVISOR . Finally, the work platform MATLAB design a genetic algorithm to find the optimization of fuel consumption and emissions . Simulation results show that the Hybrid Terminal Tractor meet the dynamic requirements economic performance and emissions are improved . In summary , the hybrid terminal tractor control strategy , of powertrain parameter design and hybrid systems optimized study has some practical significance and theoretical guidance for the development of the real car hybrid terminal tractors .
