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. Operate safely on bends

Abstract

The invention relates to a dynamic detection method of the mass center height of a freight car, which comprises the following steps, firstly, being provided with a dynamic detection device of the mass center height of a freight car, and the dynamic detection device comprises a steering wheel rotating angle measuring device, a transverse-swing angular speed measuring device, a slope angle measuring device and an electronic control unit which comprises a singlechip, a solidification program in the singlechip is provided with a dynamic detection algorithm module of the mass center height, secondly, colleting rotating angle signals of the steering wheel, transverse-swing angular speed signals of a freight car along the vertical direction, heeling angle signals of a boxcar, heeling angle signals of the rear shaft of a freight car and longitudinal vehicle speed signals of a freight car, thirdly, calculating the mass center height of a freight car through the dynamic detection algorithm module of the mass center height. The dynamic detection method can automatically and safely control a freight car through software to calculate out the maximum limiting speed of side tumbling of a freight car and through the mode of reminding a driver to decelerate or automatically enforcing to brake according to the mass center height which is calculated out in time, and can avoid traffic accidents from happening. The dynamic detection method of the mass center height of a freight car can be widely applied in the driving safety control process of various freight cars.

Description

technical field [0001] The invention relates to a method for monitoring the safety of a truck, in particular to a method for dynamically detecting the height of the center of mass of a truck. 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...
