Study of heavy truck accidents with focus on manoeuvres causing loss of control

Effects of experience and electronic stability control on low friction collision avoidance in a truck driving simulator

“…Awaiting a possible impact of increased market penetration rates, other methods have been applied to estimate potential safety benefits of heavy truck ESC. Kharrazi and Thomson (2008) studied a U.S. in-depth database of 1,070 truck crashes and found that 18.7% of these involved loss of yaw or roll control, and could thus be targeted by ESC. Woodrooffe et al (2009) combined a study of the same database with hardwarein-the-loop simulation and other methods, and were thus able to predict a prevention of around 4,700 out of an ESC-targeted annual U.S. crash population of around 11,000 (just over the 40% prevention ratio reported for passenger cars by Høye, 2011).…”

Furthermore, tests with predetermined manoeuvres, specified in terms of exact control inputs or vehicle paths, have been carried out to provide verification of stability improvements of truck ESC, both in real vehicles driven by test drivers or steering robots (Laine et al, 2008) and in computer simulation (Kharrazi and Thomson, 2008;McNaull et al, 2010).…”

Predictive yaw and lateral control in long heavy vehicles combinations

“…Lateral instability is associated with 9% of the traffic accidents involving heavy vehicles [1]. This represents a substantial figure, when translated into the absolute number of accidents, that has motivated the study of yaw and lateral stability control in heavy vehicles.…”

“…(1) 1 In Europe, this combination is only allowed in Sweden and Finland with exception on some selected roads in Denmark, Germany and The Netherlands. To form the Lagrangian, the kinetic energies of the vehicle units (truck, dolly and semitrailer) are determined individually and added together, while the potential energy contributions are neglected.…”

Predictive driver interpreter by using inverse model for heavy vehicles

“…According to [1], the loss of control by the driver represents 20% of all accidents involving heavy vehicles. These accidents can be prevented by using active safety systems.…”
