Embodiment Construction

[0018] The emergency detection method for fusing EEG signals and environmental information described in the present invention is especially suitable for severely disabled persons. Those skilled in the art can combine the existing various sensor-based obstacle detection systems with the basic equipment and principles of the present invention. Combined to further expand the assisted driving system.

[0019] The basic principle of the present invention is that when an emergency occurs, the driver imagines using the right foot to brake under stimulation, and detects the emergency braking intention by processing the driver's brain signal; then combines the braking intention detection result with the obstacle detection result , to generate the final result of emergency detection through decision rules.

[0020] An emergency detection system that fuses EEG signals and environmental information provided by the present invention will be described in detail below with reference to the a...

Abstract

The invention relates to an emergency state detection system fused with a brain electrical signal and environmental information and a related computation method thereof, which aim at improving the safety and driving experience of a brain-to-vehicle in an automatic drive process. According to the emergency state detection system fused with the brain electrical signal and the environmental information and the related computation method thereof, identification of an emergency state is implemented through brain electrical signal-based emergency brake intention detection in combination with environmental information-based obstacle detection to further enable the vehicle to brake emergently. The emergency state detection system fused with the brain electrical signal and the environmental information and the related computation method thereof are of great importance for improvement of the safety of brain-controlled drive and automatic drive and belong to an comprehensive application in the field of vehicle design as well as the fields of human-computer interaction science, cognitive neuroscience and automatic control.

Description

technical field [0001] The invention relates to an emergency detection system which fuses electroencephalogram signals and environmental information. Specifically, by processing EEG signals and environmental information, the detection of emergency braking intentions and obstacles is realized, and the judgment of emergency situations is realized through decision-making rules. The method proposed by the present invention does not require any body movement and language, and only needs the driver to imagine braking with his right foot, and obtains commands through the analysis of EEG signals and environmental information, so as to realize the braking of vehicles in emergency situations. The invention belongs to the comprehensive application of the fields of vehicle design, human-computer interaction science, cognitive neuroscience and automatic control. Background technique [0002] Many diseases cause the death of neurons and damage the neural pathways, preventing the brain fr...
