Abstract BAJA SAE is an engineering competition that challenges teams to design single-seat all-terrain vehicles that participate in a vast number of events, predominately on soft soils. Efficient performance in the events depends on the traction forces, which are dependent on the mechanical properties of the soil. To accurately model vehicle performance for each event, a model of the tire traction performance is required, and the tire model must be incorporated with a vehicle dynamics simulation. The traction forces at the soil-tire interface can be estimated using the Bekker-Wong stress integration method. However, commercially available vehicle dynamics simulation software, with a focus on on-road vehicles, does not utilize Bekker-Wong parameters. The Pacejka Magic Tire (MT) Formula is a common method for characterizing tire behavior for on-road vehicles. The parameters for the Pacejka MT Formula are usually produced by curve fitting measured tire data. The lack of available measured off-road tire data, as well as the additional variables for off-road tire performance (e.g. soil mechanics), make it difficult for BAJA SAE teams to simulate vehicle performance using commercial vehicle simulation tools. This paper discusses the process and results for estimating traction performance using the Bekker-Wong stress integration method for soft soils and then deriving the Pacejka coefficients based on the Bekker-Wong method. The process will enable teams to use the Pacejka Magic Tire Formula coefficients for simulating vehicle performance for BAJA SAE events, such as the hill climb, (off-road) land maneuverability, tractor pull, etc.

The in-wheel motor (IWM) driving system has potential applications in electric vehicles (EV) due to its high integration and controllability. However, the IWM electromagnetic excitation, which acts on the wheels, can produce negative vibration and noise issues. This paper investigates the influence of electromagnetic excitation and suppression methods. An integrated model considering the electromagnetic excitation, including the suspension system, the driving system, and the IWM system, is established and developed. A motor speed control system, which includes the acceleration and the motor braking conditions, is designed, and the characteristics of the electromagnetic excitation on the integrated model are analyzed. An active suspension model with uncertain parameters is established, and a controller based on the [Formula: see text] synthesis algorithm is developed to improve the dynamic performance of the electric vehicle. Simulation results show that the [Formula: see text] synthesis controller can significantly reduce the electromagnetic excitation of the motor by suppressing the air gap eccentricity of the IWM. Simultaneously, the [Formula: see text] synthesis controller can also improve the vehicle comfort and the road holding of the electric vehicle. For IWM-EV, the proposed modeling method can accurately describe the dynamic characteristics of IWM, and the designed controller can effectively suppress the vibration problem of IWM-EV.
