52242.基于摄像传感器的智能汽车控制系统设计与实现
[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.

52243.基于OV6620的自循迹小车路径识别技术研究
[汽车制造业] [2014-03-24]
This paper proposes extracting black line with small-scale method in the self-tracing car system based on OV6620 as the video sensor unit.Describe the hardware design of OV6620 and other two kinds of image signal extracting methods,which are to extract black line from left to right,and extract black line from middle to both sides.The testing shows that extracting black line with small-scale method has good stability,accuracy,and anti-interference.

52244.智能电动汽车电机速度控制器设计与实施
[汽车制造业] [2014-03-24]
Motor operates as the power source of the vehicles,which is one of the most important parts in the vehicle system.This paper is going to find out the speed control method of the DC motor of Golf electrical cars from both theory and practice.A virtual instrument,which produces the Pulse Width Modulation (PWM) signal,is developed with LabVIEW to control the motor speed.This smart motor speed controller differs from the traditional mechanical control of DC motor in daily life,and is instructive and significant as a new speed control method of vehicle motor.

52248.车辆碰撞相容性协议增强的评价：皮卡和SUV首要及次要能量吸收结构的有效性
[汽车制造业] [2014-03-21]
The Enhancing Vehicle-to-Vehicle Crash Compatibility Agreement (EVC) was established in 2003 as a voluntary measure to reduce occupant fatalities of passenger cars in crashes with light trucks and vans, including pickup trucks, SUVs, minivans, and full-size vans, generically abbreviated as LTVs.these results provide some evidence that the EVC has reduced fatalities but are not sufficiently strong to permit an unequivocal conclusion that it has been effective in reducing fatality risk to car occupants.
