Abstract

The invention provides an identification method suitable for different roads of a vehicle, which comprises the following steps: step 1, acquiring attitude information and speed information of the vehicle, the attitude information comprising a pitch angle and a yaw angle of the vehicle; step 2, processing the attitude information and the speed information of the vehicle acquired in the step 1, and taking the processed information as feature information substituted into a BP neural network; and step 3, substituting the feature information in the step 2 and the corresponding road category into a BP neural network for training through the BP neural network, taking the feature information as the input of the neural network, taking the corresponding road category as the output, and utilizing the trained BP neural network to identify the current road. According to the method, the speed information and the attitude information of the vehicle are extracted and substituted into the neural network for training, the recognition accuracy of the final road category is 95% or above, and a good recognition effect is achieved.

本发明提供一种适用于车辆不同道路的识别方法，包括：步骤一、获取车辆的姿态信息与速度信息，其中所述姿态信息包括车辆的俯仰角与横摆角；步骤二、对步骤一获取的车辆的姿态信息与速度信息进行处理，处理后的信息作为代入BP神经网络的特征信息；步骤三、通过BP神经网络将步骤二中的特征信息与对应道路类别代入BP神经网络进行训练，将特征信息作为神经网络的输入，对应道路类别作为输出，利用训练后的BP神经网络对当前道路进行识别。本发明将车辆的速度信息与姿态信息进行提取，并代入神经网络中进行训练，最终道路类别的识别的准确率在95％以上，有很好的识别效果。
