Abstract
A method, a device, a storage medium and a vehicle for vehicle rollover prevention warning, wherein the method for vehicle rollover prevention warning includes: collecting vehicle body rollover state parameters; calculating a lateral-load transfer rate of the vehicle according to the collected vehicle body rollover state parameters and a preset load transfer rate threshold model comprising the centrifugal force rollover moment of the sprung mass; and determining whether the vehicle has the risk of rollover or not according to the calculated lateral-load transfer rate and the preset rollover threshold. According to the technical solution provided by the invention, the load transfer rate threshold model based on the centrifugal force rollover moment of the sprung mass can simulate the actual rollover state of a vehicle more truly, with a more accurate state indication effect and a high warning accuracy.
