Claim 16:
17. A system for calibrating a driving risk identification model, comprising:
an information acquisition device, wherein the information acquisition device is mounted on a test vehicle to form a vehicle platform, and the information acquisition device is configured for collecting synchronized test data related to the test vehicle and synchronized test data related to a plurality of driving scenarios, wherein the synchronized test data related to the test vehicle comprise goal position information and motion information, accelerator pedal angle signals and brake pedal angle signals; the synchronized test data related to the plurality of driving scenarios comprise environmental types, traffic participants, traffic signs, and road signs;
a moment extraction device, wherein the moment extraction device is configured for extracting, according to the synchronized test data, first moments when 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;
a risk level definition device, wherein the risk level definition device is configured for defining risk level values respectively corresponding to the first moments, the second moments, the third moments, and the fourth moments;
a risk identification curve obtaining device, wherein the risk identification curve obtaining device is configured for obtaining a risk identification curve of the drivers in the plurality of scenarios according to the risk level values, and the risk identification curve represents a judgment of a risk level over time of the drivers; and
a calibration device, wherein the calibration device is configured for calibrating the driving risk identification model by using the risk identification curve.
