POWER ASSIST DEVICE AND AMBULATORY ASSIST VEHICLE |
摘要 |
A power assist device for assisting a user to operate an object. The power assist device includes a pressure sensor that detects an operating force applied to the object by the user; a motor that outputs and applies a motive force to the object; and a controller. The controller records a history of the operating force detected by the pressure sensor; detects a periodically fluctuating component of the operating force based on the history of the operating force; calculates a component of a current operating force caused by motion of the user operating the object; calculates a correction value that excludes the component caused by motion of the user from the current operating force; calculates a power assist force based on the correction value; and outputs the power assist force as the motive force of the motor. |

1. A power assist device for assisting a user to operate an object, comprising:
a pressure sensor that detects an operating force applied to the object by the user; a motor that outputs and applies a motive force to the object; and a controller that:
records a history of the operating force detected by the pressure sensor;detects a periodically fluctuating component of the operating force based on the history of the operating force;calculates a component of a current operating force caused by motion of the user operating the object;calculates a correction value that excludes the component caused by motion of the user from the current operating force;calculates a power assist force based on the correction value; andoutputs the power assist force as the motive force of the motor. |
