Abstract

The invention discloses an anti-rollover warning control method and system for vehicles and a hardware-in-the-loop simulation method. The anti-rollover warning control method for vehicles comprises following steps: obtaining current motion state parameters of a vehicle and then calculating vehicle rollover indexes; determining and obtaining vehicle rollover warning time according to rollover conditions and a threshold value of the rollover warning time and completing calculation of one warning period; finally, according to the rollover warning time value, determining whether there is risk of rollover; when there is the risk of rollover, performing corresponding brake control. The anti-rollover warning control method provided in the invention is reasonable; accurate and efficiency anti-rollover warning can be achieved; timely and reasonable brake control are adopted to mitigate the drive burden of drivers. Besides, by means of the provided hardware-in-the-loop simulation method based onthe anti-rollover warning control system, the anti-rollover effect of the anti-rollover warning control system can be accurately simulated.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an anti-rollover early warning control method, system and hardware-in-the-loop simulation method applicable to large vehicles such as SUVs. Background technique [0002] SUV cars refer to sports utility vehicles, which can adapt to various road conditions and are widely welcomed by the market. However, an SUV has a high center of gravity and a relatively small wheelbase. When turning at high speed, it is more prone to lateral imbalance and rollover. Therefore, the lateral stability control of SUV cars has attracted people's attention. At present, some emergency control methods are usually used to prevent the occurrence of vehicle rollover during vehicle driving, but timely warning information cannot be provided to the driver or the control system in advance. For the current prediction and alarm of the SUV rollover state, the lateral load transfer rate of the vehicle is u...
