Simulation Analysis of Uneven Ponding Road Sections Based on Driving Dynamics

In order to explore the safety of vehicles passing through the uneven water accumulation Road, a man vehicle road simulation model is established based on the driving dynamics software CarSim to simulate the driving conditions of vehicles passing through the water accumulation. According to the vehicle dynamics response index, the safety of vehicles passing through different water accumulation conditions is analyzed, and the corresponding feasible scheme is put forward. The simulation results show that when the tires on both sides of the vehicle are in contact with the water, the vehicle sideslip phenomenon is relatively slight, and the driver does not need to adjust the direction too much to keep driving normally; When only one tire of the vehicle contacts with water, the vehicle will shift to the side with water. It is suggested that the driver should turn the steering wheel to the side without water; When the tires on both sides alternately contact with water, the car body will swing slightly. It is suggested that the driver turn the steering wheel slightly to the side without water, so as to reduce the risk of cornering and maintain driving safety; In addition, deceleration can increase the safety of driving through the waterlogged Road, and the deceleration is less than 60 km/h, which is basically not affected by the waterlogging.
