52184.基于BP神经网络的CNG汽车注气控制研究
[汽车制造业] [2014-03-25]
Compressed natural gas (CNG) automobile is an emerging new energy car.How to control gas injection is the key technology of CNG electronic control system.At present,the control based on the MAP graph is used usually,but this control method has some shortages,for example larger data,poor adaptive capacity and difficulties in data updating.BP neural network control has adaptive and self-learning,nonlinear processing ability and high generalization,and faults tolerant ability in processing information.In this paper,BP neural network is used to control natural gas injection in order to solve the shortage of the MAP picture control.Simulation experiment shows thefeasibility and advantage of this method.

[橡胶和塑料制品业,汽车制造业] [2014-03-24]
Tires are an integral component of automobiles and are manufactured using raw materials such as natural rubber, nylon tire cord fabric, and carbon black. Rubber chemicals and synthetic rubber, including styrene-butadiene rubber and poly-butadiene rubber, are also used in manufacturing tires. Agriculture tires are used in different agriculture vehicles and equipment such as tractors, sowers, and harvesters. The use of advanced equipment has had a significant improvement on crop yield and hence, is leading to cultivators and farmers increasingly using agriculture vehicles and equipment.
