Abstract

The invention provides a vehicle instability pre-warning system and method. The vehicle instability pre-warning system comprises a detecting module, a data collecting module and a pre-warning module, wherein the detecting module is used for detecting a state parameter of a vehicle and providing a detection signal that expresses the state parameter; the data collecting module is used for filtering the detection signal from the detecting module so as to obtain detection data; the pre-warning module is used for judging whether vehicle turnover danger exists or not according to a surrogate function on the basis of the detection data and giving pre-warning if the vehicle turnover danger exists, wherein the surrogate function is fitted by using Kriging algorithm in advance on the basis of the detection data. As the surrogate function is built by using the Kriging algorithm, the function relation between the state parameter of the vehicle and the vehicle body stability can be established to improve the pre-warning accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of testing, and in particular to a vehicle instability warning system and method. Background technique [0002] Vehicle safety issues have been widely concerned. In particular, engineering vehicles, as a modern construction machine, are widely used in fields such as agriculture, forestry and water conservancy, energy exploitation, mining excavation, mine excavation, and cargo transportation. However, because engineering vehicles are often located in relatively harsh workplaces, and operators sometimes make mistakes, the safety of engineering vehicles has become one of the main problems, and it also seriously affects the safety of operators. [0003] Vehicle stability analysis and anti-rollover early warning are the primary foundations of the anti-rollover system. Whether the study of vehicle rollover stability and mechanism is thorough, and whether the in-depth critical state judgment is accurate d...
