The invention discloses an automobile tire health state monitoring system and method based on a piezoelectric energy harvesting hub cover, and belongs to the technical field of automobile health monitoring. Comprising a hub cover and a signal acquisition module, a plurality of mounting tables are arranged at the end of the hub cover, the mounting tables are evenly distributed in the circumferential direction of the hub cover, and piezoelectric energy harvesting parts are arranged in the mounting tables; the signal acquisition module is arranged on the hub cover and is electrically connected with the piezoelectric energy harvesting component; the signal collection module is used for collecting tire vibration information in the automobile driving process so as to extract characteristic parameters based on the tire vibration information and monitor the state of a tire through the characteristic parameters. Energy is collected through rotation of the tire in the vehicle running process, meanwhile, the energy is stored and used for detecting the health state of the tire through the sensor, the vibration sensor is used for collecting the vibration information of the tire, the health state of the tire is monitored based on the vibration information of the tire, and the problem that existing tire abnormity cannot be found in time is solved.
