Based on the results of tire handling test, the cornering properties of the tire at small side slip under different temperature are obtained, and the variation law of the parameters of tire cornering characteristic with the temperature is obtained. By establishing a tread temperature model and finite element tire model considering the influence of temperature, the mechanism of tire mechanical properties with temperature is clarified, and the expression of tread stiffness and aligning stiffness considering temperature is obtained. Then, based on the above expression and the tire mechanical characteristics with temperature, a complex brush model is established and the relationship between the temperature and the tire cornering properties is obtained. The relationship is used as the basic expression formula to establish the UniTire cornering model considering tire temperature. In order to verify the correctness of the model, four kinds of temperature state cornering data are used for parameter identification, and the tire cornering properties in the other two temperature states is predicted. The error between the simulation results of the prediction model and the experimental results is very small, which effectively proves the predictive ability of the UniTire cornering model considering tire temperature. This research is helpful to improve the application of UniTire model under different temperature condition.

根据轮胎操纵试验结果，得到了轮胎在不同温度下小侧滑时的侧偏性能，得到了轮胎侧偏特性参数随温度的变化规律。通过建立考虑温度影响的胎面温度模型和轮胎有限元模型，阐明了轮胎力学性能随温度变化的机理，得到了考虑温度的胎面刚度和对齐刚度的表达式。然后，基于上述表达式和轮胎力学特性随温度变化，建立复杂的电刷模型，得到温度与轮胎侧偏特性的关系。将该关系作为基本表达式，建立考虑轮胎温度的UniTire过弯模型。为了验证模型的正确性，采用四种温度状态过弯数据进行参数辨识，预测了另外两种温度状态下的轮胎过弯特性。预测模型的仿真结果与实验结果的误差很小，有效证明了考虑轮胎温度的UniTire转弯模型的预测能力。本研究有助于提高UniTire模型在不同温度条件下的应用。并预测其他两种温度状态下的轮胎侧偏性能。预测模型的仿真结果与实验结果的误差很小，有效证明了考虑轮胎温度的UniTire过弯模型的预测能力。本研究有助于提高UniTire模型在不同温度条件下的应用。并预测其他两种温度状态下的轮胎侧偏性能。预测模型的仿真结果与实验结果的误差很小，有效证明了考虑轮胎温度的UniTire转弯模型的预测能力。本研究有助于提高UniTire模型在不同温度条件下的应用。
