The invention relates to a power-assisted wheelchair (1) having an electric motor (32), a potentiometer (27) as means for detecting human power applied to wheels (2), and a controller (31) as means for controlling the electric motor (32) according to the detected human power so as to set the time-attenuation rate of the assist power to be greater as the human power is smaller, and to be smaller as the human power is greater. Therefore, with the invention, the coasting amount of the wheelchair (1) for small indoor movements for example is restricted to a small value. As a result, small indoor movements with a small turning radius are made possible, a sufficient coasting amount is secured for an outdoor running. Therefore, along with the possibility of a comfortable running on a level road, a steep uphill running is made easy, and the physical effort of the rider is alleviated. <IMAGE> |
