Vehicle dynamics and performance
The vehicle dynamics and performance area is developing innovative technologies for active suspensions, steer-by-wire and electronic braking systems for vehicles. The research examines control systems using multi-body vehicle system modeling, simulations and experimental validation. New control subsystems, such as controllers for active suspensions, are designed with software development tools. To study interactions among the driver, control subsystem, vehicle and environment, driver-software and hardware-in-the-loop real-time simulations are conducted using UOIT's vehicle driving simulator.
ACE facilities, including the four-post shaker, multi-axis simulation table and a chassis dynamometer, will provide world-class experimental facilities for testing and validating the physical prototypes. These are often based on vehicle control systems developed with the above software tools.
Other research areas include the improvement of vehicle design optimization, stability control, traction and vibration suppression systems. Multidisciplinary design optimization (MDO) methods are being developed to deconstruct a complicated vehicle design problem into a number of smaller and more manageable design tasks that can be executed and evaluated concurrently. Current MDO research includes development of active safety systems for heavy vehicles, and automotive brake disc design using thermal and fluid-structure interaction analysis.
