Wheel system and method for indicating status of driver

A wheel system for a vehicle body, comprising:

• a control device including
• a first wireless communication module,
• a sensing module that is configured to implement detection related to a target object in the vehicle body so as to generate sensing data, and
• a warning control module that stores a plurality of warning conditions, and a plurality of warning parameters corresponding respectively to the plurality of warning conditions, and that is configured to, in response to determining that one of the plurality of warning conditions is met based on the sensing data, obtain a corresponding one of the plurality of warning parameters that corresponds to the one of the plurality of warning conditions, and output a control signal that includes the corresponding one of the plurality of warning parameters through said first wireless communication module;
• and
• a wheel assembly adapted to be mounted on the vehicle body and including
• a wheel,
• a lighting module that is disposed on said wheel and that is configured to be controlled to emit light with one of a plurality of color patterns,
• a light control module that is disposed in said wheel, that is electrically connected to said lighting module, and that includes a second wireless communication unit configured to receive the control signal from said first wireless communication module, and a light control unit configured to control said lighting module to emit light with one of the plurality of color patterns which corresponds to the corresponding one of the plurality of warning parameters included in the control signal, and
• a power generating mechanism that is disposed on said wheel and that is configured to be driven by said wheel to generate electric power, where the electric power is to be provided to said lighting module and said light control module.
