System Identification Robust Control Vehicles Using CDGPS
2015/6/29
Automatic control of agricultural vehicles has been a research goal for many years. Previous attempts have failed largely due to sensor limitations. With the advent of modern GPS receivers, a single l...
The Effect of External Distractions on Novice and Experienced Drivers' Anticipation of Hazards and Vehicle Control
External Distractions on Novice Experienced Drivers Hazards and Vehicle Control
2014/10/22
Out-of-vehicle distractions were identified as contributing factors to about 29.4 % of all crashes that were reported between the years 1995 to 1999 (Stutts J. K., 2005; Stutts J. R., 2001). These cra...
