Driving protection system

The present invention relates to a driving protection system and, in particular, to a driving protection system incorporating a brain wave sensor and a motion sensor.

The danger of drunk driving is well known, but few people know that fatigue driving is equally deadly. Like alcohol, fatigue can reduce the reaction of driving to the outside world, reduce alertness and influence judgment. The risk of driving is comparable to that of drinking and driving. Especially when fatigue driving occurs, there are often no signs of braking, and often cause casualties. Both are more serious.

When an accident occurs, the driver often does not lose his life but is comatose because of the impact. At this time, it is a gold life-saving time. If you can immediately know the status of the driver and immediately convey the accident situation and location, it will help to avoid The tragedy happened.

In view of this, the detection system capable of detecting the fatigue driving and driving accidents in real time has yet to be proposed.

One aspect of the present invention is to provide a driving protection system including a motion sensor, a brain wave sensor, and a processor. The motion sensor is used to sense the motion state of a driver, and the brain wave sensor is used to sense the brain wave state of the driver. The processor is connected to the motion sensor and the brain wave sensor to determine whether to initiate a protective action according to the driver's motion state and brain wave state.

According to an embodiment of the present invention, the motion sensor senses a driver's head motion, and when the motion sensor senses the driver's head for a first preset time Within a predetermined number of nods, and at the same time the brainwave sensor senses that the driver's brainwave state is in an unconscious state, the processor initiates a protective action.

According to another embodiment of the present invention, the motion sensor senses one of the driver's stress states, and the motion sensor senses that the force state reaches a threshold, and at the same time, the brain wave sensor senses When the driver's brainwave state is in an unconscious state, the processor will initiate a protective action.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to Figure 1 and Figure 2. 1 is a functional block diagram of a driving protection system 1 in accordance with an embodiment of the present invention. 2 is a schematic diagram showing the appearance of a driving protection system according to an embodiment of the present invention.

As shown in FIG. 1 , the driving protection system 1 can include a motion sensor 10 , a processor 12 , a brain wave sensor 14 , a warning device 16 , and a communication unit 18 . The motion sensor 10 is used to sense the motion state of a driver, and the brain wave sensor 14 is used to sense the brain wave state of the driver. The processor 12 is connected to the motion sensor 10, the brain wave sensor 14, the alerter 16, and the communication unit 18, respectively. The processor 12 can determine whether to activate a protective action based on the state of the driver's motion and the state of the brainwave. In a specific embodiment, the driving protection system 1 of the present invention can be formed into a head-mounted form, in the form of a hat as shown in FIG. 2, and the action sensor 10 and the brain wave sensor 14 are placed. Can be as shown in Figure 2.

Please refer to FIG. 3, which illustrates a protection flow chart of a driving protection system according to an embodiment of the present invention.

In step S10, the motion sensor senses a driver's action state, and The brain wave sensor senses the brainwave state of the driver. In this embodiment, the motion sensor can sense the driver's head motion, especially for the driver's nodding in the head while driving. When a person is sitting in the driver's seat and is tired, they will want to doze off. At this time, the head will involuntarily make a nod to the action. The motion sensor can be used to detect the movement of the driver's head in the vertical direction, especially the detection. Whether the driver's head movement reaches a predetermined number of nods in a first preset time, whether a plurality of nodding actions occur in a fixed time, that is, whether there is a possibility of dozing.

However, the car also causes sloshing while traveling, so in order to avoid misjudgment, the driving protection system of the present invention senses the driver's nod condition by using the motion sensor, and sensors the driver in combination with the brain wave sensor. The brainwave state makes it more accurate to detect the driver's driving situation. According to the study, when the brain wave of a person is in a state of sleepiness and unconsciousness, the frequency of the Delta wave in the brain will be between 0 and 4 Hz. Therefore, the brain wave sensor can use this data to further detect whether the driver's nod condition is indeed due to being in a sleepy or unconscious state.

In step S12, it is detected whether the driver has too many noddings and the brain wave state is in a sleepy or unconscious state. If yes, step S14 is performed to trigger a warning. In one embodiment, the alerter can be a vibrator that uses its own vibrator to alert you to the driver to take a break. In another embodiment, the alerter can be used to alert the driver by using the driving protection system of the present invention to make a sound connection with a mobile communication device, such as a driver's mobile phone. However, in step S16, when the alarm reaches a preset number of warnings in a second preset time (that is, multiple warnings are generated in a short time, such as multiple vibrations of the vibrator), step S18 is performed to perform processing. The device can command the communication unit to connect with a mobile communication device 2 (such as a driver's mobile phone), forcibly dial a predetermined set of calls through the mobile phone to inform the relatives, or notify the employer if the driver is a professional driver, thereby reminding the driver The method of notification may be to convey a pre-recorded voice.

Please refer to FIG. 4, which is a flow chart showing the protection of the driving protection system according to another embodiment of the present invention.

In step S20, the motion sensor senses the action state of the driver, and the brain wave sensor senses the brain wave state of the driver. In this embodiment, the motion sensor can sense the state of the driver's stress, such as the impact force experienced by the car accident, and can set a force threshold. The force threshold can be accidentally occurred in a car accident on the market, causing the airbag to automatically open, that is, when the impact of -10G or more occurs.

In step S22, it is detected whether the driver is subjected to a -10G impact force and the brain wave state is in an unconscious state. If the result of the detection in step S22 is YES, then step S24 is executed, the processor may instruct the communication unit to connect with a mobile communication device (such as a driver's mobile phone), and forcibly set a predetermined set of calls through the mobile phone to inform relatives and friends, wherein The notification method may be to transmit a pre-recorded voice and to voice-transmit the GPS information of the mobile communication device. Step S26 is to detect whether the dialed preset call is turned on. Here, a dialing number can be set as a reference. For example, if the dialing cannot be turned on three times, step S28 is performed to automatically notify the police or the mobile communication device. Ambulance agency.

In summary, the driving protection system of the present invention combines a brain wave sensor with a motion sensor to accurately detect whether the driver is really tired or detect a driver's coma due to a sudden accident, so as to start immediately. A protective action to ensure the driver's driving safety and personal safety.
