AI Technical Summary

Technical Problem

In the current technology, driver status information is easily affected by dynamic disturbances during driving. Individual differences are significant and the reliability of multi-source status information is inconsistent, resulting in biased recognition results and unstable assessment results. The intensity of intervention is not well matched with the degree of risk, and the timing of intervention exit is unreasonable, which affects vehicle safety and comfort.

Method used

By collecting skin conductance signals, electromyographic correlation signals, grip force distribution signals, contact temperature signals, and vehicle behavior signals in the driver's contact area with the steering wheel, raw multimodal time-series data is generated. Distorted samples are processed by weighting using the contact effectiveness coefficient, and individual baseline parameters are established for baseline correction. Combined with emotion recognition and risk assessment, graded active intervention control commands are output.

Benefits of technology

It improves the accuracy and stability of driver status recognition, enhances the comprehensiveness and rationality of risk assessment, ensures that the intensity of intervention is commensurate with the level of risk, and improves the safety and stability of proactive intervention control.
