摘要/Abstract

摘要： 轴向和周向作用力影响湿式离合器宽速域范围工作性能。针对湿式离合器对偶片间带排转矩与轴向力演变问题，根据湿式离合器简化结构，开发湿式离合器模型流场可视化与受力测试试验装置。通过试验测试分析流场演变过程，得到对偶片间带排转矩与轴向力参数影响规律。结果表明，流场包括全液相流和气液分层流两种基本流型，在纯液相和纯气相区之间可形成一个稳定的边界。随着转速的增大、流量的减小和间隙的增加，对偶片间流场中的油液体积分数减小，两相边界向内侧移动。流量和间隙对带排转矩的拐点有显著影响，减小流量和增大间隙都可降低拐点对应的转速。随着转速增大、流量减小和间隙增加，对偶片间轴向力呈现下降趋势。在带排转矩拐点附近，轴向力的作用方向发生改变，且最终轴向力几乎减小到零。

Abstract: The driver's intention information of the front vehicle is very important to judge the danger of the rear vehicle active collision warning and avoidance model. To solve the problem of high false alarm rate and delayed braking, an active collision warning and avoidance model considering the driver's intention of the front vehicle is proposed. First, BP neural network and hidden Markov model are selected as the main model of the driving behavior layer and the driving intention layer, then, the intention recognition model is built by using the intention observation data of the front vehicle's brake pedal, accelerator pedal and speed collected by the driving simulator as input, so as to realize the recognition of the front vehicle driver's intention of accelerating driving, uniform driving, normal braking and emergency braking. Secondly, based on the intention recognition result of the driver in front and road attachment information transmitted to the rear vehicle by the Internet of Vehicles, the vehicle active collision warning and avoidance model considering the intentions of the driver in front is established to dynamically judge the collision risk and adjust the warning and braking logic. Finally, in order to verify the accuracy of the proposed driver intention recognition model and the effectiveness of the active collision warning and avoidance model, a co-simulation platform based on Simulink, Carsim and PreScan is constructed and the multi-condition experiment test is carried out. The results show that the average recognition accuracy of the proposed BP-HMM model is 94.17%, which is significantly better than that of BP or HMM models. The average positive alarm rate of the active collision warning and avoidance model is 93.43%. Compared with the TTC, Mazda and the model consider the driver's intention of following vehicle, the average false alarm rate is reduced by 16.12%, 23.43% and 26.67%, respectively. In the automatic emergency braking test condition, collision can be successfully avoided. The shortest relative distance between the two vehicles is mostly kept within the range of 2-8 m, with an average of 3.698 m, which has higher safety and stability.
