Abstract

The invention discloses a sideslip and rollover pre-warning system for vehicles on a bridge under crosswind circumstances. The sideslip and rollover pre-warning system includes a wind speed and wind direction detecting device, a road condition detecting device, and an information processing and intelligence output device. A wind speed and wind direction sensor is arranged in the wind speed and wind direction detecting device. An icing and humiture sensor is arranged in the road condition detecting device. The information processing and intelligence output device is composed of a third microcontroller, a third ZigBee communication module, a third voltage-stabilized source, and an LED display screen, wherein the third ZigBee communication module, the third voltage-stabilized source and the LED display screen are connected with the third microcontroller. According to the sideslip and rollover pre-warning system, the critical speed of vehicle sideslip or rollover is calculated according tothe vehicle strained condition to remind vehicles crossing the bridge to be driven below the speed limit, phenomena of the vehicle sideslip and the rollover when vehicles cross the bridge are avoided, and bridge road traffic accidents are reduced.

Description

technical field [0001] The present invention relates to a vehicle sideslip and rollover early warning system and method on a bridge in a crosswind environment, more specifically, to a crosswind environment that adjusts the speed limit in real time according to the detected wind speed, wind direction, and bridge road surface conditions. Vehicle sideslip and rollover warning system and method on a bridge. Background technique [0002] The total mileage of highways in my country has reached 4.3562 million kilometers, of which the total mileage of expressways has reached 104,468 kilometers. With the development of road traffic, the number of traffic accidents is also increasing, among which the number of highway accidents accounts for the largest proportion; according to the statistics of the Ministry of Public Security, in recent years, traffic safety issues have gradually become a social issue of common concern in many countries in the world. It is one of the countries with t...
