DRIVING RISK IDENTIFICATION MODEL CALIBRATION METHOD AND SYSTEM

The invention discloses a method and a system for calibrating a driving risk identification model. The calibration method comprises: S. establishing a vehicle platform by installing an information acquisition device on a test vehicle; S. acquiring synchronized test data related to the test vehicle and driving scenarios; S. extracting moments when the drivers start to press the accelerator pedal, start to release the accelerator pedal, start to press the brake pedal in the driving scenarios, and start to release the brake pedal, so as to define risk level values respectively corresponding to the moments; S. obtaining a risk identification curve of the drivers in different driving scenarios, wherein the risk identification curve represents the drivers' judgment of the risk level over time; S. using the risk identification curve to calibrate the driving risk identification model. The invention identifies the risk identification curve of the driver in different scenarios by recording the driver's operation on the vehicle platform, and then uses the risk identification curve curve to calibrate the driving risk identification model. So the calibrated driving risk identification model can adapt to the driving habits of different drivers and is conducive to improving the acceptance of the driving risk identification system.
