Abstract
Development of a micro-processor based early warning safety device that can detect and warn the drivers of impending dynamic instabilities is discussed to improve the operational safety of articulated freight vehicles. Directional dynamics of articulated freight vehicles are investigated to determine the key dynamic response parameters that can best describe the onset of rollover and jackknife instabilities. The feasibility of identified key response parameters is further investigated in view of various vehicle design and operating conditions, and ease of on-line acquisition and analyses. The study concludes that a general stability criteria can be established to identify impending roll and jackknife instabilities, and a safety monitor can be conceived to provide an early warning to the driver.
