An experimental study on the dynamic thermal environment and front and rear occupants’ local thermal sensation of the vehicle cabin in automatic air conditioning mode under different driving states in summer is conducted. Experimental results show: air temperature, occupant skin temperature and local thermal sensation are all affected by crew position, body part and driving status. Driving increases the heat flux between the vehicle body and the air outside. Driving helps reduce body part differences and improves uniformity of front and rear cabin. Local thermal sensation and local skin temperature show a good linear relationship. But the linear correlation coefficient is affected by crew position, body part, driving state and air conditioning conditions. When the air conditioning system in vehicle cabin adopts the automatic mode, the local thermal sensation under different driving status of the same body part can be unified under the same one exponential function. And the static model is more suitable to describe local thermal sensation than the dynamic model, which means that only need to consider non-uniformity and ignore transient. Substituting the local skin temperature under driving condition into a static model fitted with idle condition can predict the body’s local thermal sensation well.

对夏季不同驾驶状态下自动空调模式下车厢的动态热环境和前后乘员的局部热感进行了实验研究。实验结果表明：气温，乘员皮肤温度和局部热感都受乘员位置，身体部位和驾驶状态的影响。驾驶增加了车身与外部空气之间的热通量。驾驶有助于减少身体部位的差异，并改善前后座舱的均匀性。局部热感和局部皮肤温度显示出良好的线性关系。但是线性相关系数受乘员位置，身体部位，驾驶状态和空调条件的影响。当车厢的空调系统采用自动模式时，在相同的一个指数函数下，同一身体部位在不同驾驶状态下的局部热感可以统一。静态模型比动态模型更适合描述局部热感，这意味着只需要考虑非均匀性而忽略瞬态。将驾驶条件下的局部皮肤温度替换为适合怠速情况的静态模型，可以很好地预测人体的局部热感觉。
