This paper describes the development of a scooter supporting the mobility of older people. The scooter is equipped with a drive assistance system and a special scooter navigation system. The drive assistance system consists of a velocity controller, a steering controller, and a collision avoidance system. In this paper it is demonstrated how the challenging control and steering tasks are modified to increase safety for older people. A special scooter navigation system is presented, to support elderly people in navigating on a safe route through the city using sidewalks, pedestrian lights and crosswalks. For extended positioning requirements a hybrid positioning system was developed combining GPS, WLAN, and inertial sensor data. By combination of these technical improvements it is demonstrated how older people are able to preserve their self-determined and independent life. Usability research was done with focus groups in order to become familiar with global user demands and expectations towards a mobility assistance system. Results show that the system components are expected to assist the user in navigation, steering and speed control rather than to take complete control on the driving situation.

老年人出行协助

本文描述了支持老年人流动性的踏板车的发展。踏板车配备了驾驶辅助系统和特殊的踏板车导航系统。驾驶辅助系统由速度控制器，转向控制器和防撞系统组成。本文证明了如何修改具有挑战性的控制和转向任务以增加老年人的安全性。提出了一种特殊的踏板车导航系统，以支持老年人使用人行道，行人信号灯和人行横道在安全的路线上穿越城市。为了扩展定位要求，开发了一种混合定位系统，该系统结合了GPS，WLAN和惯性传感器数据。通过这些技术改进的结合，可以证明老年人如何保持自己的自决和独立生活。与焦点小组进行了可用性研究，以熟悉全球用户对移动辅助系统的需求和期望。结果表明，系统组件有望帮助用户进行导航，转向和速度控制，而不是完全控制驾驶情况。
