Dynamic detection method of barycenter height of truck

Abstract

The invention relates to a dynamic detection method of the barycenter height of a truck, comprising the following steps: (1) arranging a dynamic detection device of the barycenter height of a truck, which comprises a turn angle measuring device of a steering wheel, a speed measuring device of a transverse swing angle, an obliquity measuring device, and an electronic control unit which comprises asinglechip; installing a dynamic detection algorithm module of the barycenter height in a curing program in the singlechip; (2) acquiring signals of a turn angle of the steering wheel, speed signals of the transverse swing angle of the truck along the vertical direction, lateral obliquity signals of a truck carriage, lateral obliquity signals of a back shaft of the truck and longitudinal speed signals of the truck; (3) computing the barycenter height of the truck by the dynamic detection algorithm module of the barycenter height and going back to the step (2). According to the barycenter height computed in real time, the highest limit speed of the lateral turn of the truck can be computed through software, and the truck can be automatically and safely controlled in the mode of reminding adriver to decelerate or the mode of automatic and forcible braking, thereby avoiding generating traffic accidents. The method can be widely used for the driving safety control process of various trucks.

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...

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.
