This paper puts forward one kind of air-fuel ration control method which integrates improved Elman neural network with normal PI control.It constructs a model of the single LPG electro-plating engine and simulation platform for air-fuel ration controlling with GT-Power software which seamless connect to Matlab/Simulink based on JL1P39FMB single cylinder engine and develop the electronic fuel-injected controller based on Intel MCS-96. It also constructs mini LPG electro-plating engine experiment system for air-fuel ration to the LPG Injection System and adopt the new inlet channel injection type of duty ratio controlling injector. Help the throttle percentage-rev- duty cycle pulse spectrum diagram after the calibration bench experiment for the best duty cycle of mini electronic LPG-injected under the steady working conditions. It predicts the air-fuel ration signals of nontransmission delay through the Elman neural network. The normal PI controller which deals with the predictive signals implements

Flexray bus is considered as a more promising bus in the future with the performance of real-time, scalable, and fault-tolerant. In this paper we design an electric vehicle battery management system based on flexray bus, including the hardware design, the SoC estimation theory, flexray protocol design and software development. The test bench experiment results show the system design is reasonable and feasible.
