[0026] Currently, vehicle driving relies primarily on the driver. The driver needs to constantly monitor road conditions and the vehicle's movement, analyzing whether deceleration, braking, or steering is necessary. Once the driver determines that the vehicle needs to change its driving state, they must issue commands to the car by operating the steering wheel, accelerator, and brake pedals. During this process, some drivers, due to insufficient driving experience or skill, may make mistakes or omissions in maneuvering the vehicle, resulting in the driver failing to convey accurate driving intentions to the vehicle, thus leading to serious traffic accidents. Simultaneously, the driver's driving state is crucial for the normal operation of the vehicle. If the driver is in an abnormal driving state, such as experiencing a sudden illness or being inattentive, they will be unable to make correct judgments about the current driving situation, posing a safety hazard. Therefore, enabling the driver to accurately convey commands to the vehicle and monitoring the driver's driving state in real time is a challenging issue for improving vehicle driving safety.

[0027] Existing technologies have explored the use of brain-computer interface devices to collect and analyze brain signals, enabling drivers to accurately transmit instructions to vehicles. The human brain is composed of billions of neurons, each of which forms intricate connections with other neurons through thousands of synapses. Each neuron integrates inputs from upstream neurons, generates and outputs action potentials in the form of pulses, and sends them to other neurons. Non-invasive brain-computer interfaces (BCIs) typically record and decode brain signals using electrodes placed on the scalp. This technology connects the human brain directly to a computer, bypassing the process of the user transmitting commands through computer input devices. This allows the user to convey instructions that most accurately reflect their intentions. However, BCI devices require different electrode arrangements based on the unique head features of different individuals to achieve optimal signal acquisition. For vehicles, existing BCI devices cannot optimally adapt to the head features of different drivers, resulting in inefficient signal acquisition, low transmission efficiency, low signal accuracy, and poor device stability. Driving safety requires high signal stability and accuracy for deep human-machine integration. Furthermore, complex adjustments to the BCI device for different drivers can severely impact the driving experience. Therefore, designing a simple and lightweight device that automatically adjusts its position based on the driver's head features is crucial for improving the stability and signal accuracy of in-vehicle BCI devices.

[0028] Sharks possess an excellent "stereoscopic perception system," enabling them to quickly and accurately pinpoint the spatial location of prey through pheromones released by their prey. This powerful spatial positioning ability stems from their unique olfactory system structure. At the tip of a shark's nose are two distinct receptors. Because the spatial distance and angle between these two receptors and the prey are different, the potential signals received by the two sensors differ. Sharks utilize this potential difference between the receptors, as well as the potential changes during directional adjustments, to achieve real-time and accurate prey location. Inspired by the characteristics of shark noses, this invention designs an electroencephalogram (EEG) signal acquisition device, a driver state monitoring device, and a vehicle. It incorporates an adjustable shark nose electrode array plate and EEG signal receptors for sensing the strength of EEG signals and adjusting the electrode array plate accordingly. This allows the EEG signal acquisition device to adjust the electrode array plate's posture to suit different drivers, thereby achieving optimal acquisition of the user's EEG signals based on the best electrode posture.

[0029] In one specific embodiment of the present invention, an electroencephalogram (EEG) signal acquisition device includes a headband structure, a shark-nose-inspired electrode array plate, and an EEG signal sensor.

[0041] Specifically, the base of the electrodes in the aforementioned electrode array can be a cylindrical structure, with electrodes for acquiring electroencephalogram (EEG) signals attached to the top of the cylinder.

[0042] Specifically, the depth of the central groove of the aforementioned shark nose electrode array plate 1.1 can be set according to the thickness of the shark nose electrode array plate 1.1, specifically 8-12mm. The telescopic distance of the aforementioned electrode can be set according to the depth of the central groove of the aforementioned shark nose electrode array plate 1.1, specifically 3-5mm.

[0043] The groove structure and the retractable electrodes allow the electrodes to automatically adapt to the shape of the driver's head through extension and retraction, thereby ensuring that the electrodes can effectively fit the driver's head and obtain the best EEG signals. In addition, it can improve the applicability of electrodes for different drivers, while ensuring the driver's comfort when wearing the EEG signal acquisition device.

[0045] Optional, such as Figure 2 As shown, the first array plate end and the second array plate end can be semi-circular structures, and the radius R1 can be set to 25-30mm.

[0046] Optionally, the middle part of the shark-nose electrode array plate 1.1 can be set as a rectangular structure, with the length L1 set to 50-60mm and the width L2 equal to the radius of the semicircular structure mentioned above, which can be set to 25-30mm.

[0047] Optionally, the length and width of the central groove of the aforementioned shark-nose electrode array 1.1 can be set according to the dimensions of the middle part of the shark-nose electrode array plate 1.1. The length L3 can be set to 40-45mm, and the width L4 can be set to 20-25mm. The radius R2 of the rounded corners around the groove can be set according to the length and width of the central groove of the shark-nose electrode array plate 1.1, and can be set to 5mm.

[0048] Optionally, the distance between adjacent electrodes in the horizontal direction and the distance between adjacent electrodes in the vertical direction of the aforementioned EEG acquisition electrode array 1.5 can be set according to the groove size. Specifically, the distance between adjacent electrodes in the horizontal direction can be set to 3-5mm, and the distance between adjacent electrodes in the vertical direction can be set to 3-5mm, so that the electrode array is evenly distributed throughout the groove, ensuring the comprehensiveness of the driver's EEG signal acquisition.

[0049] Specifically, the arc-shaped structure and rounded corners design facilitate processing and improve the comfort of wearing the equipment, protecting the driver's head from injury by sharp corners.

[0050] Optional, such as Figure 1 As shown, the EEG signal sensor 1.3 includes a pair of EEG signal sensors, which are respectively disposed at the first array plate end and the second array plate end.

[0051] Specifically, the pairing of the aforementioned EEG signal receptors allows each receptor to automatically collect and analyze EEG signals. Based on the potential difference between the two receptors, the electrode array plate is guided to adjust its position, collecting signals in the optimal region for EEG signals, thus ensuring the robustness of the collected signals.

[0052] In addition, EEG signal receptor pairs are provided at both the first and second array plate ends of the shark-nose electrode array 1.1. This allows for better adjustment of the pose of the shark-nose electrode array by guiding the receptors at both ends, which are relatively far apart, thus achieving the optimal pose of the shark-nose electrode array.

[0053] The following describes another embodiment of the electroencephalogram (EEG) signal acquisition device, which also includes an EEG acquisition headrest device.

[0054] Optionally, the aforementioned EEG acquisition headrest device can be fixedly connected to the aforementioned headband structure.

[0064] Specifically, the radius R4 of the groove of the aforementioned EEG acquisition headrest device can be set according to the length and width of the groove of the aforementioned EEG acquisition headrest device, and can be set to 3cm.

[0065] In another specific embodiment of the present invention, a driver state monitoring device is provided, which includes an electromyography signal acquisition device, a signal analysis device, and an electroencephalogram signal acquisition device provided in any embodiment of the present invention.

[0066] The electroencephalogram (EEG) signal acquisition device is used to acquire the driver's EEG signals in real time; the electromyogram (EMG) signal acquisition device is used to acquire the EMG signals related to the driver's state in real time; and the signal analysis device is used to analyze the driver's state in real time based on the EEG and EMG signals.

[0067] Specifically, when a driver's driving state changes, such as when they become inattentive, overly fatigued, overly excited, or suffer from illness, their electroencephalogram (EEG) signals and related electromyographic (EMG) signals often change. Therefore, by analyzing EEG signals and related EMG signals, abnormal driving states of the driver can be detected in a timely and accurate manner, thereby ensuring the safe operation of the vehicle.

[0075] This invention, based on a shark-nose-inspired electrode array, utilizes EEG signal receptors to automatically collect and analyze EEG signals. Based on the potential difference between two EEG signal receptors, the electrode array adjusts its position to collect signals in the optimal EEG signal region, ensuring robust signal acquisition. The electrode bases on the array are equipped with spring-loaded telescopic structures, allowing the electrodes to automatically adapt to the driver's head shape, ensuring effective contact and optimal EEG signal acquisition. A facial electromyography (EMG) acquisition plate effectively collects EMG signals from the driver's face, while a neck EMG acquisition pillow collects EMG signals from the driver's neck. A signal analysis device then combines the facial, neck, and EEG signals to comprehensively determine the driver's driving state. When the driver's driving state is abnormal, an alert is issued promptly, further ensuring driving safety.

[0076] In another specific embodiment of the present invention, a vehicle is provided, which includes the driver status monitoring device provided in any embodiment of the present invention.

[0077] Specifically, equipping vehicles with the aforementioned driver status monitoring device can promptly and accurately analyze abnormal driver states, enabling alarms to be triggered and thus ensuring the safe operation of the vehicle.
