| Zusammenfassung: | The invention relates to a method for predicting the running speed of a vehicle on an uphill road in a plateau region. The method comprises the following steps: acquiring a designed speed of an uphill road section of a plateau region; inputting the designed speed into a pre-constructed vehicle running speed analysis model of the uphill road section of the plateau region, predicting the actual running speed of the vehicle on the uphill road section of the plateau region, and obtaining a prediction result of the actual running speed of the vehicle on the uphill road section of the plateau region; the vehicle running speed analysis model for the uphill road section in the plateau area is characterized in that nonlinear regression fitting is carried out on the speeds of different vehicle types in the plateau area under different slopes according to the sensitivity of different vehicle types to different longitudinal slopes, the expected speeds of different vehicle types in the plateau area and an ideal speed mode |
