Abstract
Many conventional road haulage vehicles include a fairing provided at the top of the cab of the vehicle. In most cases, the cab top fairing is essentially a fixed item, and so defines a set aerodynamic profile.
Adjustable cab top fairings are known, wherein the aerodynamic profile of the fairing can be altered. In practice, these are seldom adjusted and therefore fuel efficiency can be compromised. Adjustable cab top fairings are also known which use vehicle road speed to determine the fairing adjustment. However, such road speed systems are not very accurate, since they cannot account for changes in wind speed, for example. Hence, there is a need to provide improvements in the aerodynamic performance of cab top fairings.
