System and method for controlling a bicycle trainer
A system and method for controlling an exercise device are provided herein. The system includes a memory having computer-executable instructions and at least one processor to execute the computer-executable instructions to wirelessly connect the exercise device, receive a training mode, receive at least one variable for determining a power set point, determine the power set point responsive to the training mode and the at least one variable and control a magnetic brake assembly in the exercise device responsive to the power set point.
1. A method of operating a cycling trainer, comprising:
wirelessly receiving a variable value;
generating a control signal for a magnetic brake assembly of the cycling trainer, wherein generating the control signal includes providing the variable value to a physics engine including equations to simulate a bicycle ride stored in a memory;
transmitting the control signal to the magnetic brake assembly to modify a braking force applied to a flywheel member of the cycling trainer by the magnetic brake assembly; and
changing operation from a first mode in which the physics engine is used to generate control signals and a second mode in which control signals are generated without using the physics engine.
2. The method of claim 1 , further comprising measuring a rotational velocity of the flywheel member, wherein generating the control signal is further based on the rotational velocity.
3. The method of claim 1 , further comprising measuring a rotational velocity of the flywheel member using an optical sensor positioned to detect a pattern on the flywheel assembly, wherein generating the control signal is further based on the rotational velocity.
4. The method of claim 1 , further comprising measuring each of a torque using a strain gauge positioned to determine torque required to rotate the flywheel member and a rotational velocity of the flywheel member, wherein generating the control signal is further based on the rotational velocity and the torque.
5. The method of claim 1 , wherein communication between a computing element of the cycling trainer and a computing device from which the variable value was wireless received at the computing element uses at least one of ANT+ or Bluetooth communication protocols.
6. The method of claim 1 , wherein the variable value is received through an application programming interface (API).
7. The method of claim 5 , further comprising:
measuring a rotational speed of the flywheel; and
transmitting the rotational speed to the computing device.
8. A method of operating, comprising:
wirelessly receiving, at a computing element of a cycling trainer, a variable value from a computing device;
generating a control signal for a magnetic brake assembly of the cycling trainer, wherein generating the control signal includes providing the variable value to a physics engine stored in a memory of the computing element;
transmitting the control signal to the magnetic brake assembly to modify a braking force applied to a flywheel member of the cycling trainer by the magnetic brake assembly;
receiving, at the computing element, a control signal from the computing device, and
responsive to the control signal, changing a mode of the computing element from a first mode in which the computing element uses the physics engine to control the magnetic brake assembly and a second mode in which the computing element does not use the physics engine to control the magnetic brake assembly.
9. A method of operating, comprising:
wirelessly receiving, at a computing element of a cycling trainer, a variable value from a computing device;
generating a control signal for a magnetic brake assembly of the cycling trainer, wherein generating the control signal includes providing the variable value to a physics engine stored in a memory of the computing element;
transmitting the control signal to the magnetic brake assembly to modify a braking force applied to a flywheel member of the cycling trainer by the magnetic brake assembly;
receiving, at the computing element, a control signal from the computing device, and
responsive to the control signal, changing a mode of the computing element from a first mode in which the computing element uses the physics engine to control the magnetic brake assembly and a second mode in which the computing element controls the magnetic brake assembly based on a power set point.
