Vehicle control method based on multi-modal biofeedback

Abstract

The invention discloses a vehicle control method based on multi-mode biological feedback, and relates to the technical field of intelligent vehicle man-machine interaction. The method comprises the following steps: collecting physiological data of a driver through a biosensor and carrying out data preprocessing to obtain multi-modal features; the multi-modal features are mapped to three emotion dimensions, a quantitative relation is established, weights of the emotion dimensions are preliminarily distributed according to the recognized driving scene, a comprehensive emotion index of the driver is calculated, and a driving risk level is determined according to the comprehensive emotion index; and according to the driving risk levels, environment adjustment and automatic driving takeover strategies are triggered layer by layer, vehicle control based on multi-modal biofeedback is carried out, and weight distribution rules of three emotion dimensions in comprehensive emotion index calculation are optimized by analyzing historical data. The method can effectively reduce the risk of traffic accidents caused by the out-of-control emotion, improves the recognition, response and optimization capability of a vehicle control system on driving risks, and has remarkable practical value and technical popularization significance.
