    The invention discloses a vehicle passenger thermal environment parameter algorithm, which comprises a vehicle air conditioning system, CFD simulation analysis software and an air conditioner dummy test system, and is characterized in that related conditions of an air blower, sun irradiation and air conditioner air outlet temperature and humidity acting on an air conditioner dummy are simulated in the CFD simulation analysis software; according to the vehicle passenger thermal environment monitoring method adopting the algorithm, the existing air conditioner air outlet temperature and humidity sensor, the sunshine sensor, the vehicle exterior temperature sensor and the air conditioner return air inlet temperature and humidity sensor are utilized, and on the premise that no sensor is additionally arranged, the vehicle passenger thermal environment monitoring algorithm is simple in calculation step and efficient in operation. By reading existing data such as vehicle-mounted GPS signals, the thermal environment where the human body is located is calculated according to the algorithm, the thermal environment of the whole passenger and the thermal environment of all parts of the body can be monitored in real time, and a foundation is laid for taking the thermal comfort of the human body as a target of an intelligent air conditioner control object in the next step and improving the comfort of the intelligent air conditioner.
