Abstract: Traditionally the kewords selection of web search data is a manual selection task.It is difficult to take all the keywords into consideration.Therefore,the deep learning method is introduced into the field of automobile sales prediction,and the deep learning model is used to extract features of web search data.At first,car-related keywords and online search volumes are collectedthrough web crawlers,and then a car sales prediction model of convolutional neural network is designed,based on the characteristics of web search data and sales data.The model is adopted to predict the sales of Volkswagen in the first half of 2019.The results show that the convolutional neural network can effectively predict car sales,and the accuracy of the prediction reaches 89.51%,compared with RBF,ARIMA and ARIMA+RBF model.Due to the impact of the Spring Festival and the implementation of new policies,it has the largest forecast error in February.However,it has the highest prediction accuracy in March as the market recovers.

Key words: Baidu index, Convolutional neural network, Sales forecast, Volkswagen
