The invention relates to the technical field of automobile safety early warning, in particular to a new energy automobile parking space safety early warning system. The system comprises an environment sensing unit which collects environment data around a parking space in real time; the positioning and navigation unit obtains the relative position and dynamic information of the vehicle and the parking space based on the surrounding environment data; and the data processing and analyzing unit analyzes the information acquired by the positioning and navigation unit, and analyzes the abnormal state of the vehicle around the parking space based on the surrounding environment model. Optimization of a ramp environment and a vehicle attitude is introduced, an adaptive function for a ramp inclination angle and a vehicle pitching angle is added into an optimized kernel function, the distance between a vehicle and a parking space can be accurately calculated, attitude change caused by a ramp is considered, and therefore the adaptability of a model to a ramp parking environment is improved, and the accuracy of the model is improved. And the safety early warning capability of the system during ramp parking is ensured.
