The invention discloses a vehicle rollover warning method. By analyzing vehicle speed and a vehicle steering angle which cause lateral acceleration of a vehicle, and by combining a static rollover threshold value of the vehicle, a dynamic rollover threshold value of the vehicle is determined; according to the method, by directly adopting the lateral acceleration as a warning calculating parameter, after a signal has no delay, more sufficient and effective warning time can be provided so as to remind a driver to adopt reasonable control, so the vehicle driving safety is promoted. Through verification, the method has a very obvious prediction function on non-tripped rollover caused by curve driving and over-high vehicle speed, and has certain application value; moreover, the existing sensor widely applied is adopted by the rollover warning method, so a rollover warning function can be realized on the basis that hardware is not added, and the cost is further reduced.
