Research On Vehicle Driving Safety Monitoring System Based On The Handling

Vehicle safety has always been an important research direction in the field of vehicleengineering, for the tire pressure, vehicle speed and other factors which cause hydroplaning,standing waves and instability to directly affect the safety of vehicle, aiming at the vehicledriving safety, researches on vehicle driving safety monitoring principles and methods basedon the handling, designs and verifies the vehicle driving safety monitoring system based onhandling, to promote the development of vehicle safety technology has the importantacademic value and practical significance.The paper first describes the importance of the tire pressure on vehicle driving safety,this paper analyzes the hydroplaning, standing waves, maneuverability and monitoringsystems research status at home and abroad, According to the vehicle dynamics, investigatesthe tire pressure and vehicle speed to influence mechanism of hydroplaning, tire standingwaves and instability, proposes vehicle driving safety monitoring principle and method basedon handling, designs the corresponding monitoring system for vehicle safe driving. On thisbasis, aiming at the vehicle driving safety, using Matlab/Simulink simulation software to buildtire simulation model of considering tire pressure factors, vehicle dynamics simulation model,hydroplaning simulation model and tire standing waves simulation model, through simulationanalysis, the critical speed of the vehicle has hydroplaning and standing waves, and therelationship between tire pressure and vehicle handling in different water film thickness, tirepressure and tread of driving conditions, discusses tire pressure, hydroplaning phenomenonand standing waves monitoring methods in the process of vehicle driving. Finally, builds thevehicle safe driving monitoring system, the monitoring experiment to verify the validity of theexperiment system for the vehicle safety monitoring.
