Driver emotion recognition-based automatic driving mode switching system

Abstract

The invention discloses an automatic driving mode switching method based on driver emotion recognition, which includes a driver's physiological information monitoring module, a road rage state recognition module, a driving mode switching module and an automatic driving module; the driver's physiological information monitoring module includes The heart rate and blood oxygen sensors at both ends of the horizontal axis of the steering wheel; the road rage state recognition module constructs the off-line training of driver anger and the online recognition model for online recognition of driver anger; the driving mode switching module is judged by the road rage state recognition module When the driver is in an angry mood, switch the driving mode of the vehicle to the automatic driving mode to disable the driver's operation on the car. When it is confirmed that the driver is ready to take over, the driving mode switching module switches the driving mode of the vehicle from the automatic driving mode to the automatic driving mode. The manual driving mode; the automatic driving mode module includes the ACC system for realizing the longitudinal automatic control of the vehicle and the LKA system for realizing the lateral automatic control of the vehicle.

Description

technical field [0001] The invention relates to an automobile safety auxiliary driving mode switching system, in particular to an automatic driving mode switching system based on driver emotion recognition. Background technique [0002] With the popularization of automobiles, people's lives are increasingly inseparable from automobiles, and the relationship between driver anger and traffic accidents is becoming more and more obvious. Therefore, knowing the change of driving anger can help avoid traffic accidents. [0003] During the driving process, the driver often encounters situations that cause great changes in the driver's emotions, such as traffic jams, poor road conditions, vehicle breakdowns, conflicts with other drivers or pedestrians, and other objective events. Some physiological indicators of the driver (such as heart rate, blood oxygen) change with the driver's mood. When the driver is subjected to stress changes caused by objective events, the activation leve...
