In recent years, road vehicle automation has become an important and popular topic for researchudand development in both academic and industrial spheres. New developments receivedudextensive coverage in the popular press, and it may be said that the topic has captured theudpublic imagination. Indeed, the topic has generated interest across a wide range of academic,udindustry and governmental communities, well beyond vehicle engineering; these include computerudscience, transportation, urban planning, legal, social science and psychology. While thisudfollows a similar surge of interest – and subsequent hiatus – of Automated Highway Systemsudin the 1990’s, the current level of interest is substantially greater, and current expectationsudare high. It is common to frame the new technologies under the banner of “self-driving cars”ud– robotic systems potentially taking over the entire role of the human driver, a capability thatuddoes not fully exist at present. However, this single vision leads one to ignore the existingudrange of automated systems that are both feasible and useful. Recent developments are underpinnedudby substantial and long-term trends in “computerisation” of the automobile, withuddevelopments in sensors, actuators and control technologies to spur the new developments inudboth industry and academia. In this paper we review the evolution of the intelligent vehicleudand the supporting technologies with a focus on the progress and key challenges for vehicleudsystem dynamics. A number of relevant themes around driving automation are explored inudthis article, with special focus on those most relevant to the underlying vehicle system dynamics.udOne conclusion is that increased precision is needed in sensing and controlling vehicleudmotions, a trend that can mimic that of the aerospace industry, and similarly benefit fromudincreased use of redundant by-wire actuators.
