[汽车制造业] [2014-03-24]
In this paper we propose a intelligent vehicle system design with MK60NS12VMD100 as the micro-controller unit and CMOS image sensor to obtain image information of the track.Our proposed comparator circuit instead of an A/D conversion to obtain the binary image enables us to achieve a bigger field of view and a higher processing speed.A unique algorithm to extract track information and to successfully extract the black guide line is devised.We also design a PID closed-loop control to adjust the rotate speed of driving electromotor and direction of steering electromotor.The results indicate that our design proposal is feasible.The intelligent vehicle could successfully achieve a high speed,while maintaining an excellent stability.

[汽车制造业] [2014-03-24]
Simulation model of automobile power train has been built using ADVISOR,on the basis of Genetic Algorithm Tool Box,the paper takes a mini car as example to carry out performance simulation calculation and power train parametric optimization design.The result show that automobile power performance and fuel economy and emission performance have been greatly improved. It is an important approach to optimize its matching parameters on reducing the fuel wastage,improving dynamical performance and decreasing the emission of waste gas. It is a better approach to cope with automobile power train match optimization by integrating ADVISOR's accurate simulation with Genetic Algorithtn's searching optimization with high efficiency.
