Book excerpt: High-speed testing procedures for evaluating the lateral stability of multi-trailer articulated heavy vehicles (MTAHV) include the use of both an open-loop and a closed-loop maneuvers as specified in ISO-14791. The standard testing procedures are used to determine the Rearward Amplification (RA), which is a well-accepted performance measure for the lateral stability of MTAHVs. The open-loop testing maneuver includes the use of a single cycle sinewave steer input, while the closed-loop procedure prescribes a single lane-change path, following which a driver drives a testing vehicle. The closed-loop single lane-change maneuver can be performed by a human driver for in-vehicle tests. In numerical simulation, a driver model may be used to drive the virtual vehicle under the closed-loop maneuver for simplicity and repeatability. Very little attention has been paid to investigating into the interactions of driver-MTAHV. It has been reported that a driver is typically at fault in many heavy vehicle accidents, and many studies focus on improving the dynamic performance of the vehicle and ignore the driving skills of the driver. This thesis attempts to examine the driver-MTAHV interactions and quantify driver skills for controlling a MTAHV as compared to a single unit vehicle. This thesis proposes a method for driver skill analysis via comparing virtual drivers in various operating conditions. The driver skill analysis is conducted by evaluating the lateral stability and path-following ability of the vehicle under the control of the driver model. The evaluation is implemented using driver-in-the-loop (DIL) real-time simulations, where the RA measures derived from a group of human drivers are compared to those from the virtual driver. The numerical and DIL real-time simulation results demonstrate that the human and the virtual driver achieved similar a good agreement in terms of the performance measures, indicating the validity of the driver model, testing procedure and the interactions of driver-MTAHV.

Available in PDF, EPUB and Kindle. Book excerpt: The International Symposium on Dynamics of Vehicles on Roads and Tracks is the leading international gathering of scientists and engineers from academia and industry in the field of ground vehicle dynamics to present and exchange their latest innovations and breakthroughs. Established in Vienna in 1977, the International Association of Vehicle System Dynamics (IAVSD) has since held its biennial symposia throughout Europe and in the USA, Canada, Japan, South Africa and China. The main objectives of IAVSD are to promote the development of the science of vehicle dynamics and to encourage engineering applications of this field of science, to inform scientists and engineers on the current state-of-the-art in the field of vehicle dynamics and to broaden contacts among persons and organisations of the various countries engaged in scientific research and development in the field of vehicle dynamics and related areas. IAVSD 2017, the 25th Symposium of the International Association of Vehicle System Dynamics was hosted by the Centre for Railway Engineering at Central Queensland University, Rockhampton, Australia in August 2017. The symposium focused on the following topics related to road and rail vehicles and trains: dynamics and stability; vibration and comfort; suspension; steering; traction and braking; active safety systems; advanced driver assistance systems; autonomous road and rail vehicles; adhesion and friction; wheel-rail contact; tyre-road interaction; aerodynamics and crosswind; pantograph-catenary dynamics; modelling and simulation; driver-vehicle interaction; field and laboratory testing; vehicle control and mechatronics; performance and optimization; instrumentation and condition monitoring; and environmental considerations. Providing a comprehensive review of the latest innovative developments and practical applications in road and rail vehicle dynamics, the 213 papers now published in these proceedings will contribute greatly to a better understanding of related problems and will serve as a reference for researchers and engineers active in this specialised field.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Articulated heavy duty vehicles are widely used around the world for its economic and environmental benefits. A-train double is one of the most popular heavy duty vehicles in Canada. Despite its advantages, the spread of A-train is hampered by poor lateral dynamic performance and poor accident avoid ability in highway resulted from its special structure. In order to evaluate the lateral dynamic performance of the A-train double at highway speed, ISO standards have proposed the rearward amplification (RA) measures to characterizing the performance. It has been reported that the RA curves obtained through three different methods proposed by ISO-14791 differ. This thesis studies three proposed methods in detail and analyzes the contributing causes for the inconsistency among three test maneuvers based on A-train double. In order to increase the lateral stability of the A-train double, Active steering systems (ATS) have been designed through two methods: robust LQR-LMI method with genetic algorithm (GA) optimization and H∞ method. The designed controllers are validated by numerical simulation and hardware in-loop simulation. The ATS designed from two methods show good robust stability and improve the lateral dynamic performance of A-train double dramatically at highway speed.

This book was released on 2019 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growing development of autonomous and semi-autonomous large commercial heavy vehicles, the lateral stability control of articulated vehicles have caught the attention of researchers recently. Active vehicle front steering (AFS) can enhance the handling performance and stability of articulated vehicles for an emergency highway maneuver scenario. However, with large vehicles such tractor-trailers, the system becomes more complex to control and there is an increased occurrence of instabilities. This research investigates a new control scheme based on fractional calculus as a technique that ensures lateral stability of articulated large heavy vehicles during evasive highway maneuvering scenarios. The control method is first implemented to a passenger vehicle model with 2-axles based on the well-known “bicycle model”. The model is then extended and applied onto larger three-axle commercial heavy vehicles in platooning operations. To validate the proposed new control algorithm, the system is linearized and a fractional order PI state feedback control is developed based on the linearized model. Then using Matlab/Simulink, the developed fractional-order linear controller is implemented onto the non-linear tractor-trailer dynamic model. The tractor-trailer system is modeled based on the conventional integer-order techniques and then a non-integer linear controller is developed to control the system. Overall, results confirm that the proposed controller improves the lateral stability of a tractor-trailer response time by 20% as compared to a professional truck driver during an evasive highway maneuvering scenario. In addition, the effects of variable truck cargo loading and longitudinal speed are evaluated to confirm the robustness of the new control method under a variety of potential operating conditions.
