In society today, 4-wheeled vehicles are common for usage as they offer comfortable mobility and safety for the passengers. However, tadpole-type three-wheeled vehicles can be used as an alternative as they have the comfort and safety of cars with the energy consumption of motorcycles. However, their limited stability and handling causes rollover risk, especially during cornering. This study focuses on analyzing the handling characteristics of a tadpole three-wheeled vehicle as well as propose a new design for a combined steering and tilt mechanism to decrease understeering. A multibody dynamics model of the vehicle will use Universal Mechanism (UM) software to model vehicle behavior under a range of operating scenarios in realistic driving conditions, using a circular path test and a obstacle avoidance test under varying speeds. The handling metrics evaluated include steering angle, lateral acceleration, and yaw rate. The results of the simulation will investigate the impact of vehicle design and suspension parameters on stability behavior. These results will help readers understand the trade-offs that are considered between good handling and ride comfort, offering feedback for future research for the tilt-steering mechanism design.
