Not only handicapped people but also elderly people living in Hokkaido, the northernmost island in Japan, desire to participate in outdoor activities during a winter season that is characterized by heavy snow and low temperatures. Most of these people venture outdoors to go shopping or to hospitals, even under severe conditions. A wheelchair is generally used for outdoor transport. There are, however, many problems with using a wheelchair during the winter ; roads covered with snow and ice are very slippery, casters are easily burid in snow, and handrims are too cold to handle. Therefore, an appropriate wheelchair for outdoor use during the winter season is greatly desired. We are developing an electric wheelchair with four drived wheels to be effective for outdoor use during the winter. In this work, three types of electric wheelchairs with front-wheel drive, rear-wheel drive and four wheels were tested for drivability on icy roads, snow-covered roads, and indoor floors. In addition, computational methods were proposed to simulate the drivability of electric wheelchairs under snowy conditions.

在大雪、低温的冬季，不仅是残疾人，生活在日本最北端岛屿北海道的老年人也渴望参加户外活动。即使在恶劣的条件下，大多数人也会冒险到户外去购物或去医院。轮椅通常用于户外交通。然而，冬季使用轮椅也存在很多问题；冰雪覆盖的道路非常滑，脚轮很容易被雪埋住，手轮又冷又难以操作。因此，非常需要一种适合冬季户外使用的轮椅。我们正在开发一种带有四个驱动轮的电动轮椅，可有效地在冬季户外使用。本次工作对前轮驱动、后轮驱动和四轮三种电动轮椅在结冰路面、积雪路面和室内地板上进行了驾驶性能测试。此外，还提出了模拟雪天条件下电动轮椅驾驶性能的计算方法。
