Characterization of infield vehicle activity data and exhaust emissions from diesel powered off-road vehicles
… on steady-state and transient cycles. Two vehicles were evaluated in this study, a streetsweeper (114 hp) and a rubber-tired loader (110 hp). Due to the lack of appropriate transient cycles available for these vehicles, methods were developed to document infield operation for the creation …

Investigation into and design of an automatic restraint system for ROPS-equipped off-road vehicles
Agriculture consistently ranks as one of the most dangerous occupations based on an overall work death rate. Tractor overturns, by far the single largest cause of death on farms, account for approximately 19% of all on-farm deaths. The concept of a Roll-over Protective Structure (ROPS) came into …

Design and analysis of active aerodynamic control systems for increasing the safety of high-speed road vehicles
The lateral stability and the safety of road vehicles is dependent on the vehicle design and operating conditions. Under operating conditions such as slippery roads, high lateral acceleration and tight cornering, the forces and torques due to the interactions between the tire and road may be …

Design of dust-filtering algorithms for LiDAR sensors in off-road vehicles using the AI and non-AI methods
The performance of Lidar sensors degrades in the presence of dust. These particles can impact sensor measurements and cause robot perception algorithms to misinterpret data. This thesis proposes two distinct dust filtering methods to address this issue. These methods utilize both AI and non-AI …

Torque control strategy for off-road vehicle mobility.
Multi-wheeled off-road vehicles behavior depend not only on the total provided power by the engine but also on the power distribution among the drive axles/wheels. In turn, this distribution is primarily regulated by the drivetrain layout and the torque distribution devices. At the output of the …

An Investigation of Turbulence and Diffusion within Vehicle Wakes and On-Road Measurements using an Instrumented Mobile Car and a Stationary Roadside Monitoring System
Moving motor vehicles emit pollutants that negatively impact human health. Stationary roadside measurements alone are not sufficient to quantify the pollutant–flow interactions that occur behind moving vehicles. The instrumented mobile car however is well–suited for on–road measurements, but has …
