摘要: 车辙是引起雨天车辆发生水漂现象的重要因素之一。通过分析车辆在积水路面上的横向稳定性和操纵性机理,提出了一种在积水条件下考虑行车安全的车辙安全性评价方法,应用CarSim软件模拟不同车速条件下汽车的侧向加速度和横向偏移量,建立了车辙严重程度评价指标。研究表明,当汽车行驶速度超过80 km/h时,汽车侧向加速度和横向偏移量增长较快,且极易超过安全阈值;在积水路段,汽车的横向偏移量一般会首先超过安全阈值,而当车辙长度达到失稳的安全阈值时,汽车操纵稳定性将变为0。

Abstract: Rutting is one of the important factors for vehicle hydroplaning in raining days. Based on the analysis of vehicle driveability and lateral stability on the pavement covered by water, the rutting safety evaluation method considering driving safety under the condition of road waterlogging was put forward. Using the CarSim software to simulate vehicle lateral offset and lateral acceleration with different speeds, the rutting evaluation indicators on driving safety were set up. It shows that vehicle lateral offset and lateral acceleration increase quickly and exceed the safety threshold easily when more than 80km/h speed. On the rutting pavement covered by water, vehicle lateral offset may exceed the safety threshold firstly, and the vehicle may lose its driveability when rutting length is long enough to arrive the instability threshold.

Key words: rutting length, simulation analysis, vehicle driving safety, vehicle dynamics model, lateral offset
