Research on Rear Wheel Steering Small Electric Vehicle (Effect of Driving Torque to Vehicle Dynamics)

摘要

Concern over fuel consumption and ride comfort of a vehicle has been increasing in the recent years. Furthermore, environmental impact of the petroleum-based transportation infrastructure, along with the peak oil, has led to renewed interest in an electric transportation infrastructure. The problem with the electric vehicle in the market now is that the angle of cornering is not small enough to be fully used in narrow road. This research will explain about motion characteristic of rear wheel steering small Electric Vehicle (EV). The difference in torque from both rear wheel is used to control the steering of the vehicle and thus give more freedom on the maneuvering of the vehicle. This will improve the cornering of the vehicle and has the advantage of moving easily in a small space. In this research, the first simulation is to know the basic of this mechanism which is different amount of torque input is given in the same direction while the second simulation process is to know the effect of ratio of torque difference to the effectiveness of vehicle steering.
