Narrow vehicles like motorcycles can promote significantly improved highway utilization through the use of half-width lanes. However, in order for the general public to adopt this form of personal transportation, narrow vehicles should perceptibly provide the same ease of use and the same level of safety as passenger sedans. This project explores some fundamental technologies that can make the development of such a prototype narrow vehicle feasible. The project aims to develop a concept narrow vehicle that will be relatively tall compared to its track width so as to provide a travel height that is comparable to that of other vehicles on the highway. To help the driver balance a relatively tall, narrow vehicle, it will incorporate an electronic tilt control system that ensures tilt stability. The tilt control system will balance the vehicle and improve ease of use, especially on curves where the vehicle must lean into the curve to ensure tilt stability. The vehicle will be designed to provide crash protection for its occupants that is significantly superior to that of a motorcycle. Several fundamental challenges are addressed in this exploratory project in order to make the development of the concept narrow vehicle described above a practical reality. These include the development of a direct tilt control system that can operate with a compact motor, synchronization of the tilting of the vehicle with its turning so as to minimize actuator effort and the development of a steer-by-wire system in which the front wheel steering angle is used to control tilt while at the same time perceptibly allowing the driver to use the steering angle for purposes of lateral control.Significant matching funds for the project are provided by the ITS Institute, University of Minnesota. Successful completion of the exploratory project will enable the research team to solicit funding from industries for further development as well as to write regular full proposals to NSF and other funding agencies. The project promotes cross-disciplinary research by combining significant activities in controls, dynamics, sensor electronics and vehicle design. In addition to its direct impact on transportation through the development of a new personal transportation vehicle, the project is also likely to contribute to improvement of other highway vehicle systems in general.

像摩托车这样的狭窄车辆可以通过使用半宽道车道来显着改善高速公路利用率。 但是，为了使公众采用这种形式的个人运输方式，狭窄的车辆应明确提供与客运轿车相同的易用性和相同的安全水平。 该项目探讨了一些基本技术，这些技术可以使这种原型狭窄的车辆可行。该项目旨在开发一种概念狭窄的车辆，该车辆将与其轨道宽度相比相对较高，以便提供与高速公路上其他车辆相当的旅行高度。 为了帮助驾驶员平衡相对较高的狭窄车辆，它将结合一个电子倾斜控制系统，以确保倾斜稳定性。 倾斜控制系统将平衡车辆并提高易用性，尤其是在车辆必须倾斜到曲线以确保倾斜稳定性的曲线上。 该车辆的设计目的是为其乘员提供碰撞保护，该乘员比摩托车的乘员要优越。 这个探索性项目中提出了一些基本挑战，以使上述实际现实所描述的概念狭窄的车辆的发展。 其中包括开发直接倾斜控制系统，该系统可以通过紧凑的电机运行，倾斜与转弯的倾斜同步，以最大程度地减少执行器的努力以及开发前轮转向角度的转向系统，在该系统中，该系统用于控制倾斜度，同时允许驾驶员在驾驶员的同时使用驾驶员进行介绍，以供驾驶员进行介绍，以实现朝向的介绍。明尼苏达大学。 探索项目的成功完成将使研究团队能够从行业获得进一步发展的资金，并为NSF和其他资助机构撰写定期的完整建议。该项目通过结合控制，动力学，传感器电子和车辆设计中的重要活动来促进跨学科研究。 除了通过开发新的个人运输工具对运输的直接影响外，该项目还可能有助于改善其他一般的高速公路车辆系统。
