Claim 0:
1. A method for calibrating a driving risk identification model, comprising:
S1, establishing a vehicle platform by installing an information acquisition device on a test vehicle;
S2, performing freely driving tests; and acquiring synchronized test data related to the test vehicle and a plurality of driving scenarios, wherein in the freely driving tests, drivers drive the vehicle platform in the plurality of driving scenarios;
S3, according to the synchronized test data, extracting first moments when the drivers start to press an accelerator pedal in the plurality of driving scenarios, second moments when the drivers start to release the accelerator pedal in the plurality of driving scenarios, third moments when the drivers start to press a brake pedal in the plurality of driving scenarios, and fourth moments when the drivers start to release the brake pedal in the plurality of driving scenarios to define risk level values respectively corresponding to the first moments, the second moments, the third moments, and the fourth moments;
S4, according to the risk level values, obtaining a risk identification curve of the drivers in the plurality of driving scenarios through curve fitting, wherein the risk identification curve represents a judgment of a risk level over time of the drivers; and
S5, using the risk identification curve to calibrate the driving risk identification model.
