Driver emotion recognition-based automatic driving mode switching system

Abstract

The invention discloses a driver emotion recognition-based automatic driving mode switching system, which comprises a driver physiological information monitoring module, a road rage status recognitionmodule, a driving mode switching module and an automatic driving module, wherein the driver physiological information monitoring module comprises heart rate and blood oxygen sensors arranged at the two end parts of the horizontal axis of a steering wheel, and the road rage status recognition module constructs an off-line training and online recognition model of driver rage emotion to perform online recognition of the driver rage emotion; when the road rage status recognition module judges that a driver is angry, the driving mode switching module switches a vehicle driving mode into an automatic driving mode to disable the operation of the driver on a vehicle; when confirming that the driver is ready for taking over, the driving mode switching module switches the vehicle driving mode fromthe automatic driving mode into a manual driving mode; the automatic driving mode module comprises an ACC (Adaptive Cruise Control) system for realizing longitudinal automatic control of a vehicle andan LKA (Lane Keeping Assistance) system for realizing 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...
