Vehicle rollover accidents have been a serious safety problem for the last three decades. Although
rollovers are a small percentage of all trac accidents, they do account for a large proportion of severe
and fatal injuries. Specically, some large passenger vehicles, such as large vans, pickup trucks, and sport
utility vehicles, are more prone to rollover accidents with a high center of gravity (CG) and narrow track
width. Vehicle rollover accidents may be grouped into two categories: tripped and untripped rollovers. A
tripped rollover commonly occurs when a vehicle skids and digs its tires into soft soil or hits a tripping
mechanism such as a curb with a suciently large lateral velocity. On the other hand, the untripped
rollover is induced by extreme maneuvers during critical driving situations, such as excessive speed during
cornering, obstacle avoidance, and severe lane change maneuver. In these situations, the forces at the tire-
road contact point are large enough to cause the vehicle to roll over. Furthermore, vehicle rollover may
occur due to external disturbances such as side-wind and steering excitation. erefore, it is necessary
to investigate the dynamic stability and control of tripped and untripped vehicle rollover so as to avoid
vehicle rollover accidents.
In this book, dierent dynamic models are used to describe the vehicle rollover under both
untripped and special tripped situations. From the vehicle dynamics theory, rollover indices are deduced,
and the dynamic stabilities of vehicle rollover are analyzed. In addition, some active control strategies are
discussed to improve the anti-rollover performance of the vehicle.

e automotive industry has entered a transformational period that will see an unprecedented
evolution in the technological capabilities of vehicles. Significant advances in new manufacturing
techniques, low-cost sensors, high processing power, and ubiquitous real-time access to information
mean that vehicles are rapidly changing and growing in complexity. ese new
technologies—including the inevitable evolution toward autonomous vehicles—will ultimately
deliver substantial benefits to drivers, passengers, and the environment. Synthesis Lectures on
Advances in Automotive Technology Series is intended to introduce such new transformational
technologies in the automotive industry to its readers.
