Abstract
An exercise device comprises a flywheel, a driving assembly, and a control assembly. The driving assembly drives the flywheel to rotate. The control assembly comprises an angle sensor for measuring the change of angular displacement of the flywheel during a specific period of time. The control assembly calculates the angular velocity or the angular acceleration of the flywheel by the measured angular displacement during the specific period of time. The control assembly determines if the flywheel is to be stopped according to at least a criterion.
Claims10
An exercise device, comprising:
- a flywheel;
- a driving assembly for driving the flywheel;
- and
- a control assembly comprising an angle sensor for measuring the change of angular displacement of the flywheel during a specific period of time, the control assembly calculating the angular velocity or the angular acceleration of the flywheel by the measured angular displacement, and the control assembly determining if the flywheel is to be stopped according to at least a criterion.
An automatic braking method for an exercise device comprising a flywheel, a driving assembly driving the flywheel, and a control assembly comprising an angle sensor and executing the automatic braking method, which comprises the steps of:
- measuring a radian or an angle of a rotational movement of the flywheel during a predetermined period of time;
- calculating an angular velocity or an angular acceleration of the flywheel by the measured angular displacement during the predetermined period of time;
- determining if the flywheel is to be stopped according to at least a criterion.
