Dynamic detection method for preventing wagon from turning towards one side on bending road and pre-warning apparatus

Abstract

The invention relates to a rollover prevention dynamic detection method for a wagon on a curved conduit and a warning device. The method comprises the following steps: 1, installing a rollover prevention dynamic detection method for a wagon on a curved conduit which comprises a steering wheel rotation angle measuring device, a yaw angle velocity measuring device, an inclination angle measuring device and an electronic control unit which comprises a single chip microcomputer, wherein a solidification program of the single chip microcomputer is equipped with a centroid height dynamic detection algorithm module and a rollover prevention warning algorithm module, and a rollover alarming range is arranged in the rollover prevention warning algorithm module. 2, collecting steering wheel rotation angle singles, vertical yaw angle velocity measuring singles of the wagon, side-tipping angle singles of a carriage of the wagon, the side-tipping angle singles of a rear shaft of the wagon and vertical speed singles of the wagon. 3, a lateral acceleration and a centroid height of the wagon is counted through the centroid height dynamic detection algorithm module. 4, counting a rollover acceleration threshold value through the rollover prevention warning algorithm module according to the centroid height. 5, sending a corresponding alarm command according to a difference value of the lateral acceleration and the rollover acceleration threshold value of the wagon and the reset rollover alarm range.

Description

technical field [0001] The invention relates to a truck safety monitoring method and device, in particular to a truck curve anti-rollover dynamic detection method and an early warning device. Background technique [0002] When the truck is transporting goods, the height of its center of mass often changes due to the different types and weights of the goods loaded. If the height of the center of mass is high and the vehicle speed is fast, the truck is prone to rollover accidents when driving on a curve, causing heavy casualties and property losses. Therefore, domestic and foreign are actively researching on the operation safety and monitoring technology of trucks, such as the intelligent vehicle speed system, which realizes automatic control of vehicle speed according to road conditions and vehicle performance parameters, so that the vehicle can safely pass through curves; another example Based on vehicle-road coordination safety control technology, through vehicle-road comm...

Problems solved by technology

Therefore, for the current detection technology of the height of the center of mass of the truck, there are mainly the following problems: First, because the type and weight of the goods loaded on the truck often change, the existing detection technology is not targeted, when the loaded goods change It is difficult to know the actual height of the center of mass of the truck; second, it is difficult to guarantee the real-time accuracy of the height of the center of mass of the truck detected by the existing technology, which leads to the inaccuracy of the vehicle safety control algorithm based on the height of the center of mass of the truck, so it cannot effectively protect the truck.
