Rollover early warning method, device, storage medium and vehicle

Abstract

The invention discloses a rollover prewarning method, a rollover prewarning device, a storage medium and a vehicle. The method comprises the following steps: acquiring displacement sensor data and speed information of a to-be-pre-warned vehicle; determining transverse load transfer rate of the to-be-pre-warned vehicle according to the displacement sensor data and the speed information; and determining a comparison result of the transverse load transfer rate and a set pre-warning value and prompting the comparison result according to a set rollover danger grade. According to the scheme, the problem that the safety of a multishaft commercial vehicle is poor as the multishaft commercial vehicle turning and changing lanes and the like during high speed driving is easy to rollover can be solved, and an effect of enhancing the safety is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and specifically relates to a rollover warning method, device, storage medium and vehicle, in particular to a method and a device for realizing a rollover prevention warning system for a multi-axis air suspension vehicle based on a wheel speed difference load transfer rate model , storage media and vehicles. Background technique [0002] Vehicle rollover is a serious road traffic accident. It is more prone to rollover accidents for passenger and truck vehicles with a high center of mass. With the demand for load, there are more and more multi-axle commercial vehicles. When maneuvering on roads, etc., rollover accidents are very likely to occur. [0003] We usually use the lateral load transfer ratio LTR as the rollover threshold of the rollover warning system. Among them, LTR=(F L -F R ) / (F L +F R ), that is, the difference between the vertical loads on the left and right tires of the v...
