Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The following describes a safe driving system for a vehicle and a vehicle according to an embodiment of the present utility model with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a safe driving system for a vehicle according to an embodiment of the present utility model. Referring to fig. 1, the vehicle safe driving system 100 includes: an EEG measuring machine 100, a lane departure warning system 120 and a controller 130.

Wherein the EEG measuring machine 110 is configured to measure EEG values of the driver; the lane departure warning system 120 is configured to issue warning information when a lane departure of the vehicle occurs; the controller 130 is connected to the EEG measuring machine 110 and the lane departure warning system 120, respectively, and is configured to adjust the warning volume of the lane departure warning system in accordance with the EEG values.

Specifically, a portable, easy-to-wear, lightweight, wireless-linkable, two-channel EEG (Electroencephalogram) meter may be used to detect the brain wave signals of the driver. As one example, after the driver gets on the vehicle, the vehicle may acquire brain wave signals of the driver in real time through a headset EEG gauge worn by the driver.

Note that brain wave signals generated by the human body in different mental states are different. For example, when the driver is in a normal concentration state or a vigilance state, the brain wave signal generated by the driver is a beta wave signal with a frequency of 8-12Hz (hertz); when the driver is tired in driving due to long-time driving or self-tired or pressure, i.e. the driver is tired (such as drowsiness of the driver), the β wave energy value generated by the driver will be significantly reduced, and the α wave (frequency of which is 8-13 Hz) energy value and the θ wave (frequency of which is 4-8 Hz) energy value will be significantly increased. Accordingly, the degree of fatigue of the driver can be determined based on the change in the brain waves of the driver.

After the brain wave signals of the driver are acquired, the vehicle calculates the alpha wave energy value, the beta wave energy value and the theta wave energy value in the brain wave signals in real time, calculates the sum value of the alpha wave energy value and the theta wave energy value to obtain a first energy value, and calculates the ratio of the first energy value to the beta wave energy value to obtain an EEG value, namely a fatigue value.

It should be noted that, during driving, the type of the brain wave signal of the driver is continuously changed along with the change of the mental state of the driver, so that the final calculated EEG value is also changed along with the change of the brain wave.

As an example, assuming that the alpha, beta, and theta wave energy values generated by the driver at time t are A, B and C, respectively, the EEG value of the current driver isAssuming that the driver's fatigue increases with the driving time, the alpha wave energy value generated by the driver at time t+1 decreases to D, the beta wave energy value and the theta wave energy value increase to E and F, respectively, and the EEG value at time t+1 becomes +.>

In addition, when the driver is tired, the hands of the driver can be separated from the steering wheel, so that the vehicle is out of control and deviates from a lane in which the driver normally runs, and the driver can be seriously harmed, and vehicles or pedestrians in the periphery of the vehicle which normally run can be harmed. Therefore, in the embodiment of the present utility model, the lane departure warning system 120 (LaneDepartureWarningSystem, LDWS) is further configured to send warning information to alert the user when the lane departure occurs.

After the EEG measuring machine 110 measures the EEG value of the driver, the EEG value is transmitted to the controller 130, and the controller 130 can adjust the pre-warning volume of the lane departure pre-warning system 120 according to the difference of the EEG values, so as to give different degrees of warning stimulus to the driver, so as to meet multiple requirements of user safety, experience and the like.

Specifically, a plurality of critical thresholds, such as a first threshold and a second threshold, may be set for the fatigue value according to the basic research result, the first threshold and the second threshold may be 3 and 4, respectively, and when the fatigue value satisfies different threshold ranges, the controller 130 may control the lane departure warning system 120 to give the driver an unused warning according to different warning volumes.

As one example, when the EEG value is greater than 3 and less than 4, and the vehicle is in a non-P range (indicating that the vehicle is in a start-up state or running state), the controller 130 may control the vehicle deviation pre-warning system 120 to turn on the alert function, and turn up the alert volume of the LDWS to a first preset decibel, such as 85 decibel; when the EEG value is equal to or greater than 4 and the vehicle is in the non-P range, the controller 130 increases the warning volume of the lane departure warning system 120 to a second preset decibel, for example, 95 decibel; when the EEG value is less than 3, the warning volume of the lane departure warning system 120 is turned down to a third preset decibel, for example 80 decibel.

Therefore, the EEG measuring machine measures the EEG value of the driver, and the controller controls the lane departure warning system to give warning stimulus to the driver in different degrees according to different warning volumes, so that the occurrence of boring and tension emotion of home use caused by high-strength fatigue warning can be effectively avoided when the fatigue degree of the driver is not high, and multiple demand experiences can be provided for the driver while the safety of the driver is ensured.

In some embodiments, referring to fig. 2, the vehicle safe driving system 100 further includes: a vehicle collision warning system 140. The vehicle collision warning system 140 is configured to issue warning information when the vehicle is at risk of collision; the controller 130 is also coupled to the vehicle collision warning system 140 and is configured to adjust the warning volume of the vehicle collision warning system based on the EEG values.

It will be appreciated that when the driver is tired, the vehicle may be involved in a rear-end collision due to inattention or in a collision due to lane departure. Therefore, in the embodiment of the present utility model, the vehicle collision pre-warning system 140 is further configured to send pre-warning information to alert the user when the vehicle has a collision risk.

Specifically, the controller 130 may control different pre-warning volumes of the case of the vehicle collision pre-warning system 140 to remind the driver according to different EEG values, so as to give different degrees of warning stimulus to the driver, so as to satisfy multiple requirements of user safety, experience, and the like.

As an example, when the fatigue value is greater than 3 and less than 4 and the vehicle is in a non-P gear, the controller 130 may control the vehicle collision warning system 140 to turn on the warning function, and turn the vehicle collision warning volume up to a fourth preset decibel, for example 85 decibel; when the fatigue value is equal to or greater than 4 and the vehicle is in the non-P range, the controller 130 increases the reminding volume of the vehicle collision warning system 140 to a fifth preset decibel, for example, 95 decibel; when the fatigue value is less than 3, the vehicle collision warning sound volume is reduced to a sixth preset decibel, for example 80 decibel.

Therefore, the EEG measuring machine measures the EEG value of the driver, and the controller controls the vehicle collision early warning system to give warning stimulus to the driver in different degrees according to different early warning volumes, so that the occurrence of boring and tension emotion of home use caused by high-strength fatigue warning can be effectively avoided when the fatigue degree of the driver is not high, and multiple demand experiences can be provided for the driver while the safety of the driver is ensured.

In some embodiments, the vehicle safe driving system 100 further includes: sound equipment (not shown). The controller 130 is further connected to the sound, and the controller 130 is further configured to control the sound to issue a safe driving reminder according to the EEG value.

Specifically, the controller can control the sound equipment to send different safe driving reminding information according to the difference of the EEG values.

As an example, when the EEG value is greater than 3 and less than 4, and the vehicle is in a non-P range, the controller 130 may control the sound to emit a 95 db alert tone, where the alert tone may be in the manner of: the sound equipment gives out a beep prompt tone for 2 times/s; when the EEG value is equal to or greater than 4 and the vehicle is in the non-P range, the controller 130 controls the sound to emit a 95 db alert sound, where the alert sound may be: the sound sounds a beep prompt tone for 3 times/s; when the EEG value is less than 3, indicating that the degree of EEG of the driver is not high, the controller 130 may control the vehicle not to sound a warning sound.

In some embodiments, the vehicle safe driving system 100 further includes: a positioning system and a navigation system (not shown in the figures). The positioning system is configured to obtain location information of the vehicle; the navigation system is configured to provide a parking navigation path to a driver; the controller is also respectively connected with the positioning system and the navigation system and is configured to control the navigation system to provide a parking navigation path according to the EEG value and the position information after the control sound sends out the safe driving reminding information.

It should be noted that, considering the difference between the driving scenes of the urban driving road and the highway driving road, in the embodiment of the utility model, different scenerization function recommendations can be provided for the driver according to the current positions of multiple places of the vehicle.

The current position information of the vehicle can be obtained through a positioning system configured on the vehicle, such as GSP, or can be obtained through a navigation system on a mobile phone, wherein the current position information of the vehicle can comprise a highway or a non-highway, and the controller 130 can control the navigation system to provide a corresponding parking navigation path according to the EEG value and the difference of the current position information of the vehicle after controlling the sound to send out the safe driving reminding information.

As one example, when the EEG value is less than 3, and the current location of the driver is detected by the positioning system to be on the highway, the controller 130 may control the navigation system on the vehicle to automatically search for and display the nearest service area; when the EEG value is less than 3 and it is detected that the driver's current location is on a non-highway, the controller 130 may control the navigation system on the vehicle to automatically search for and display the nearest parking lot.

In some embodiments, the vehicle safe driving system 100 further includes: a human-machine interaction device and a navigation system (not shown in the figure), the human-machine interaction device being configured to receive a navigation instruction of a driver; a navigation system configured to provide a driver with a parking navigation path; the controller 130 is further connected to the man-machine interaction device and the navigation system, and is configured to control the navigation system to provide a parking navigation path according to the navigation instruction after the control sound sends out the safe driving reminding information.

In particular, in order to provide a better riding experience for the driver, in the present novel embodiment of use, a human-computer interaction device and a navigation device are also configured.

As an example, when the current position of the driver is located on the expressway, the controller 130 may control the sound to send a reminding message to the driver in a voice interaction manner, so as to remind the driver of whether to enter the service area for rest, and when receiving a navigation instruction that the driver needs to enter the service area for rest, control the navigation system to automatically search and display the nearest service area, and control the vehicle to automatically navigate to the nearest service area; when the current position of the driver is located on a non-expressway, the controller 130 can send out reminding information to the driver in a voice interaction mode to remind the driver of whether the driver needs to enter a parking lot for rest, and when the driver determines that the driver needs to enter the parking lot for rest, the navigation system on the vehicle is controlled to automatically search and display the nearest parking lot, and the vehicle is controlled to automatically navigate to drive to the nearest parking lot.

As another example, the driver may also actively issue a navigation instruction according to his own will. For example, when the current position of the driver is located on the expressway, if the driver wants to enter the service area for rest, the driver can send a voice navigation instruction for entering the service area for rest to the man-machine interaction device, and the controller 130 can control the navigation system to automatically search and display the nearest service area and control the vehicle to automatically navigate to the nearest service area when receiving the voice navigation instruction for entering the service area for the driver through man-machine interaction; when the current position of the driver is located on a non-expressway, if the driver wants to enter a parking lot for rest, the driver can send a voice navigation instruction for entering the parking lot for rest to the man-machine interaction equipment, and the controller 130 can control the navigation system on the vehicle to automatically search and display the nearest parking lot and control the vehicle to automatically navigate to the nearest parking lot when receiving the voice navigation instruction for entering the parking lot through man-machine interaction.
