The invention relates to an LSTM-DTW-based heavy vehicle rollover early warning method, in particular to a method for performing trend prediction by using an LSTM neural network on the premise of performing S-G filtering on a vehicle motion parameter roll angle speed to effectively reduce noise and keeping signal original information, and performing DTW template matching on a predicted curve and a standard template to finally realize rollover identification. The method is characterized by comprising the following steps: acquiring a vehicle rollover curve template; 2, predicting the trend of the driving state of the vehicle in a future time period; and step 3, predicting curve template matching rollover identification.
本发明一种基于LSTM‑DTW重型车辆侧翻预警方法，具体是涉及对车辆运动参数侧倾角速度进行S‑G滤波有效降噪并保持信号原始信息的前提下利用LSTM神经网络进行趋势预测，将预测后的曲线与标准模板进行DTW模板匹配最终实现侧翻识别。其特征在于，该方法包括以下步骤：车辆侧翻曲线模板的获取；步骤二、车辆未来时间段内行驶状态的趋势预测；步骤三、预测曲线模板匹配侧翻识别。
