The present invention relates to a vehicle sterilization management system and a vehicle sterilization management method. More specifically, the composite sterilization unit for sterilizing the mat of the vehicle by irradiating ultraviolet rays and transmitting the mat sterilization completion information including time information for sterilizing the mat of the vehicle； A UV irradiation unit that sterilizes the seat of the vehicle by transmitting ultraviolet rays and transmits the sheet sterilization complete information including time information for sterilizing the seat of the vehicle； An air-conditioning sterilization unit that sprays a chemical solution in a mist form to sterilize the air conditioning unit of the vehicle and transmits air conditioning sterilization completion information including time information required for sterilizing the air conditioning unit of the vehicle； And receiving the mat sterilization completion information, sheet sterilization completion information and air conditioning sterilization completion information transmitted from the composite sterilization unit, UV irradiation unit and air conditioning sterilization unit, and receiving the received mat sterilization completion information, sheet sterilization completion information and air conditioning sterilization completion. And a control unit for generating and transmitting the sterilization completion information of the vehicle by comparing the information with the standard sterilization information. According to the present invention, the mat sterilization complete information, the sheet sterilization complete information and the air conditioning sterilization completed from the composite sterilization part sterilizing the vehicle mat, the UV irradiation part sterilizing the vehicle seat, and the air conditioning sterilization part sterilizing the vehicle air conditioning part Compared with the standard sterilization information, there is an effect that can control whether the ca
