Description

Fatigue driving judgment system and method

A judgment system and method thereof, in particular, refers to a fatigue driving judgment system and method thereof which automatically controls a vehicle to turn on the flashing lights and move to an outer lane to shut down the vehicle when the driver is fatigued, thereby improving road traffic safety.

Drivers will inevitably become tired after driving for a long time, which may lead to loss of driving concentration or sleep due to fatigue. These will undoubtedly cause concerns about road traffic safety.

The existing method of providing driver fatigue judgment is usually to remind the driver through external stimulation (such as playing warning sounds, vibrating seats, etc.) when the driver is judged to be tired and warn the driver that he needs to rest to relieve fatigue in order to avoid major traffic accidents. However, the external stimulation provided by the driver fatigue judgment can only provide reminders and warnings to normal drivers. If the driver is in a coma due to poor physical condition, the external stimulation will not be able to provide reminders and warnings to the comatose driver.

In summary, it can be seen that the prior art has long had the problem that the driver has been unconscious due to poor physical condition, resulting in the ineffectiveness of the existing externally stimulated fatigue warning. Therefore, it is necessary to propose an improved technical means to solve this problem.

In view of the problem in the prior art that the driver may fall into a coma due to poor physical condition, which results in the failure of the existing fatigue warning by external stimulation, the present invention discloses a fatigue driving judgment system and method, wherein:

The calculation module of the on-board computer analyzes the recorded driving information and calculates the fatigue warning value. The judgment module of the on-board computer determines the fatigue warning value based on the driver's brain waves and the driver's The driver's physiological data determines the driver's physiological state; the generation module of the on-board computer generates a control instruction when the fatigue warning value is greater than or equal to a preset warning value and the driver's physiological state is a sleeping state, and generates a control instruction and emergency information when the fatigue warning value is greater than or equal to a preset warning value and the driver's physiological state is a coma; and the transmission module of the on-board computer transmits the emergency information to an emergency center.

The following will be used in conjunction with drawings and embodiments to explain the implementation of the present invention in detail, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

The following first describes the fatigue driving judgment system disclosed in the present invention, and please refer to "Figure 1", which is a system block diagram of the fatigue driving judgment system of the present invention.

The fatigue driving judgment system disclosed in the present invention includes: an electroencephalogram detection device 10, a wearable device 20 and a vehicle-mounted computer 30. The vehicle-mounted computer 30 further includes: a recording module 31, a receiving module 32, a calculation module 33, a judgment module 34, a generation module 35 and a transmission module 36.

The brain wave detection device 10 is installed in the headrest of the driver's seat in the car to detect the driver's brain waves. The wearable device 20 is worn on the driver to detect the driver's physiological data. The aforementioned physiological data is, for example, blood pressure, pulse, etc. The brain wave detection device 10 and the wearable device 20 are connected to the vehicle computer 30 through a wireless transmission method. The aforementioned wireless transmission method is, for example, Wi-Fi, Bluetooth, mobile communication network, etc. This is only used as an example to illustrate, and the application scope of the present invention is not limited thereto.

The vehicle-mounted computer 30 is installed in the vehicle. The recording module 31 of the vehicle-mounted computer 30 records the driving information of the vehicle while it is driving. The driving information includes, for example, engine load, engine running time, driving speed, temperature inside the vehicle, etc. These are only given as examples and are not intended to limit the scope of application of the present invention. In addition, the receiving module 32 of the vehicle-mounted computer 30 receives the driver's brain waves from the brain wave detection device 10 and receives the driver's physiological data from the wearable device 20.

The calculation module 33 of the vehicle computer 30 analyzes the recorded driving information and calculates the fatigue warning value. The vehicle computer 30 pre-establishes different data ranges and corresponding preset values for each data item in the driving information (i.e., engine load, engine running time, driving speed, vehicle temperature, etc.). The calculation module 33 of the vehicle computer 30 finds the fatigue warning value. The fatigue warning value can be calculated by adding up the preset values corresponding to each data item in the driving information. It is worth noting that the fatigue warning value calculated by the calculation module 33 of the vehicle computer 30 will continue to accumulate and calculate based on the driving information of the vehicle that is continuously recorded by the recording module 31 of the vehicle computer 30 until the vehicle is turned off and the fatigue warning value is reset to zero.

Specifically, assuming that the data ranges corresponding to the engine running time are 0 to 1 hour, 1 to 2 hours, and 2 to 3 hours, the default value corresponding to 0 to 1 hour is 10, the default value corresponding to 1 to 2 hours is 20, and the default value corresponding to 2 to 3 hours is 30. This is only an example for illustration, and the scope of application of the present invention is not limited thereto; assuming that the data ranges corresponding to the temperature inside the vehicle are 20 to 25 degrees, 26 to 30 degrees, and 31 to 35 degrees, the default value corresponding to 20 to 25 degrees is 10, the default value corresponding to 26 to 30 degrees is 20, and the default value corresponding to 31 to 35 degrees is 30. This is only an example for illustration, and the scope of application of the present invention is not limited thereto.

Next, the judgment module 34 of the vehicle-mounted computer 30 judges the driver's physiological state according to the driver's brain waves and the driver's physiological data. The vehicle-mounted computer 30 pre-establishes brain waves of different physiological states and physiological data of different physiological states. The driver's brain waves and the driver's physiological data are analyzed based on the pre-established brain waves of different physiological states and physiological data of different physiological states to judge the driver's physiological state.

Specifically, the driver's physiological state is assumed to be a sleeping state, the brain waves corresponding to the sleeping state are sleep brain waves, and the physiological data are heart rate 50 to 57, blood pressure 100 to 110 and 70 to 80, respectively; the brain waves corresponding to the coma state are coma brain waves, and the physiological data are heart rate above 95 and below 49, blood pressure above 180 and above 95, respectively. This is only an example to illustrate, and the scope of application of the present invention is not limited to this.

When the fatigue warning value is greater than or equal to the preset warning value and the driver's physiological state is a sleeping state, the generation module 35 of the onboard computer 30 generates a control instruction. The onboard computer 30 controls the vehicle to switch to automatic driving and turn on the flashing lights according to the control instruction. The automatic driving state controls the vehicle to move to the outer lane and then turns off the vehicle to avoid major traffic accidents.

When the fatigue warning value is greater than or equal to the preset warning value and the driver's physiological state is a coma, a control instruction and emergency information are generated. The onboard computer 30 controls the vehicle to switch to automatic driving and turn on the flashing lights according to the control instruction. The automatic driving state controls the vehicle to move to the outer lane and then turns off the vehicle to avoid major traffic accidents.

At the same time, the emergency information can be transmitted to the emergency center through the transmission module 36 of the vehicle-mounted computer 30. The emergency center notifies the nearby ambulance and the police and fire departments to rescue the driver of the car according to the location information of the emergency information.

Next, the operating system and method of the first embodiment of the present invention will be described below using the first embodiment, and please refer to "Figure 2A" and "Figure 2B" at the same time. "Figure 2A" and "Figure 2B" are method flow charts of the fatigue driving judgment method of the present invention.
