Power assisted vehicle |
摘要 |
A number of embodiments of power-assisted manually operated vehicles, specifically wheelchairs. An arrangement is providing for sensing the amount of manual force inputted and then providing a power assist related to that input force. Once the operator either decreases the input of the manual force or discontinues it, the power assist is maintained for a predetermined time period so as to provide further assist. The power assist is reduced either gradually or in steps and may be held constant for a time before or after the power reduction. This provides a more natural effect and still reduces the necessity for operator input. Separate controls are provided for each of the wheels and a helper assist is also provided.
