Analytical Model for Calculating the Speed at Starting Hydroplaning in Unmanned Control Algorithms

This paper presents an analytical model for vehicle speed calculations at starting aquaplaning in real-time road conditions. High percentage of accidents associated with speed violations in adverse weather conditions makes the study relevant. A mathematical model based on the integral equations of mass and momentum conservation taking into account the tire geometric parameters, water film characteristics and those of the road surface has been developed. The proposed model makes it possible to calculate the critical speed of aquaplaning initiation for a specific vehicle. The paper presents the results of the simulation researching various factors affecting the aquaplaning initiation speed according to the developed model. The results of the study can be used for improving road safety including the unmanned vehicle operation, transport infrastructure design, as well as carrying out vehicle expertise and ensuring an aircraft take-off and landing safety.
