Anthropomimetic Control Synthesis: Adaptive Vehicle Traction Control
… and outputs. In the case of longitudinal vehicle traction, this work will show a direct correlation in longitudinal acceleration to throttle input in a controlled laboratory environment. In fact, human experts have the ability to control a vehicle at or near the performance limits, with respect to …

Traction Control Study for a Scaled Automated Robotic Car
This thesis presents the use of sliding mode control applied to a 1/10th scale robotic car to operate at a desired slip. Controlling the robot car at any desired slip has a direct relation to the amount of force that is applied to the driving wheels based on road surface conditions. For this model, …

A lumped-parameter model of tire-terrain interactions for off-road vehicles
The inclusion of various electronic control units in modern vehicles, such as the anti-lock brake systems, the traction control systems, and the electronic stability control have improved vehicle performance and stability. Design and tuning of such control units requires large amounts of trial and …

Model-based powertrain design and control system development for the ideal all-wheel drive electric vehicle
… AWDEV (IAWDEV) powertrain architecture and its control schemes were proposed by this research; the architecture has four independent driving motors in powertrain. The IAWDEV gives more control freedoms to implement active torque controls and traction mode controls. In essence, this research came …
