Torque Vectoring To Maximize Straight-Line Efficiency In An All-Electric Vehicle With Independent Rear Motor Control, William Blake Brown Dec 2021

Torque Vectoring To Maximize Straight-Line Efficiency In An All-Electric Vehicle With Independent Rear Motor Control, William Blake Brown

Theses and Dissertations

BEVs are a critical pathway towards achieving energy independence and meeting greenhouse and pollutant gas reduction goals in the current and future transportation sector [1]. Automotive manufacturers are increasingly investing in the refinement of electric vehicles as they are becoming an increasingly popular response to the global need for reduced transportation emissions. Therefore, there is a desire to extract the most fuel economy from a vehicle as possible. Some areas that manufacturers spend much effort on include minimizing the vehicle’s mass, body drag coefficient, and drag within the powertrain. When these values are defined or unchangeable, interest is driven to …


Nrj Rc Baja Vehicle Project - Transmission, Suspension, And Body Systems, Jeffrey Ryan Harn Jan 2021

Nrj Rc Baja Vehicle Project - Transmission, Suspension, And Body Systems, Jeffrey Ryan Harn

All Undergraduate Projects

Students of Central Washington University’s Mechanical Engineering technology program were tasked with designing, manufacturing, and testing a remote-controlled scale vehicle for the American Society of Mechanical Engineers (ASME) Radio-Controlled (RC) Baja Car Contest sanctioned by Remotely Operated Auto Racers (ROAR). A team of three students was assembled and responsibility over the sections of the RC vehicle were divided amongst the three students. This report focuses on the design, manufacture, testing, and evaluation of the suspension and transmission systems of the RC vehicle. A suspension tower component and transmission housing assembly were conceived to satisfy the RC suspension and transmission systems. …


Modeling Operational Performance Of Urban Roads With Heterogeneous Traffic Conditions, Swapneel R. Kodupuganti, Sonu Mathew, Srinivas S. Pulugurtha Jan 2021

Modeling Operational Performance Of Urban Roads With Heterogeneous Traffic Conditions, Swapneel R. Kodupuganti, Sonu Mathew, Srinivas S. Pulugurtha

Mineta Transportation Institute

The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous …


Hydraulic Vehicle Challenge, Jacob Steiner, David Kotovets, Evan Blitz, Luke Fetherston, Alex Colucy Jan 2021

Hydraulic Vehicle Challenge, Jacob Steiner, David Kotovets, Evan Blitz, Luke Fetherston, Alex Colucy

Williams Honors College, Honors Research Projects

The target goal of this project is for a team of students to design a vehicle which is based on human power as the primary mover of the system and achieves vehicle propulsion through the required use of hydraulics and pneumatics. In summary, the rider will power a pump that will generate pressure in order to move the fluid that drives the motor. This will result in the powered rotation of the wheels. As there are many possible designs, naturally, this means that the final design for the vehicle will have specific limitations such as weight and the required use …
