52021.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.

52025.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.
