| 摘 要： | 汽车纵向主动避撞系统应能根据路面状态的突变自动地调整安全距离以提高系统的可靠性。在魔术公式的基础上,给出了基于车轮动力学参数识别路面的方法,建立了车辆动力学模型,分别对汽车行驶在高、低附着系数路面和组合路面上避撞系统的工作进行了模拟试验。试验结果表明,识别的路面状态与实际路面一致性良好,具备路面识别系统的汽车纵向主动避撞系统对路面具有自适应性,其安全性高于没有路面识别系统的避撞系统,从而有效避免了变路面上汽车碰撞的发生。

| Abstract: | Vehicle forward collision avoidance system must be able to regulate the safety distance according to the abrupt variation of road automatically to promote the reliability when road varied.A road identification approach was proposed based on wheel dynamics parameters and vehicle dynamics model was established with the application of Magic Formula model.Then simulation tests were conducted on the high and low adhesion coefficient road as well as combination road respectively,which results showed that the iden... |
