The invention discloses a vehicle rollover prevention control method, system, device and equipment and a storage medium. The method comprises the steps that vehicle parameter data and a rollover threshold value are obtained; calculating a rollover evaluation value according to the vehicle parameter data; the rollover evaluation value and the rollover threshold value are compared, if the rollover evaluation value is larger than or equal to the rollover threshold value, the vehicle has the rollover risk, the additional value of the front wheel turning angle is calculated according to the rollover evaluation value, the vehicle is adjusted, the control time is shortened, the vehicle can have more response time for rollover prevention control, and the rollover risk of the vehicle is reduced. The timeliness of active rollover prevention of the vehicle is improved; when the rollover evaluation value is smaller than the rollover threshold value, a rollover derivative prediction index value is further calculated, and whether rollover prevention control is involved or not is judged according to the rollover derivative prediction index value. The joint mechanism of the rollover evaluation value and the rollover derivative prediction index value ensures that the vehicle can have better response time under the conditions of normal driving and abnormal driving so as to realize active rollover prevention control.
本发明公开了一种车辆防侧翻控制方法、系统、装置、设备及存储介质,方法包括获取车辆参数数据和侧翻门限值;根据车辆参数数据计算侧翻评价值;比较侧翻评价值和侧翻门限值,如果侧翻评价值大于等于侧翻门限值,则车辆具有侧翻风险,根据侧翻评价值计算前轮转角附加值,对车辆进行调整,减小了控制时间,使车辆能够有更多的反应时间进行防侧翻控制,提升了车辆主动防侧翻的及时性;当侧翻评价值小于侧翻门限值,进一步计算侧翻导数预测指标值,根据侧翻导数预测指标值判断防侧翻控制是否介入。侧翻评价值和侧翻导数预测指标值的联合机制保障了车辆在正常驾驶与非正常驾驶情况下车辆都能有更好的反应时间实现主动防侧翻控制。
