Course Goals This course explores the system dynamics and controls involved in modern engineered vehicles, with a primary emphasis on ground mobility applications. The focus is on both on-road and off-road wheeled vehicles, and other classes of vehicles may be studied depending on current interests. The course is offered for both undergraduate and graduate students. The course may also examine vehicle subsystems, classified as those systems that perform functions directly related to mobility and/or safety enhancement. The essentials of control system design will be introduced to support understanding of vehicle subsystem development. The purpose of the course is to convey fundamental concepts in control systems, and extensive background is this area is not expected. This course was created to balance the offerings in the Thermal/Fluid Sciences area that have an emphasis on engines/powerplant engineering as well as formula car development. The emphasis in this course is on the dynamics and controls aspects of vehicle system dynamics. See the semester schedule for typical topics, lecture summaries, homeworks and projects. |

Course Objectives To develop an understanding of vehicles and vehicle subsystems by using system analysis tools with the intent of increasing our capacity to design modern and future vehicle systems, and understand these systems well enough to provide design support and diagnostic input. To develop analytical/computational skills useful in vehicle system analysis and control design, especially using modern computational tools used in engineering practice. |

|
Introduction to the static and dynamic stability characteristics of transportation vehicles with examples drawn primarily on- and off-the-road ground vehicles, but also rail cars and boats. Emphasis on a systems approach to automotive analysis and design. Specific topics include vehicle structures, suspension steering, brakes, and driveline. Basic vehicle dynamics in the performance and handling modes will be discussed. Static and dynamic properties and performance of the pneumatic tire for on and off-road will be reviewed. Modeling for predicting directional response and stability in small and large disturbance maneuvers will be presented, along with simulation methods. Methods for closed-loop control of vehicle systems will be discussed, including modern approaches in in vehicle stability, handling, and traction control. Ride phenomena treated as a random process will be introduced, especially for applications in vehicle harshness and testing. The role of modern electronic systems, sensors and actuators in vehicle systems will be discussed. The course will rely on development of computer-based models and simulation algorithms using engineering software. Course Textbook: J.Y.
