[0035] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0037] In the prior art, cars have become one of the indispensable means of transportation for current families. However, due to the irregular driving of some people, cars have brought convenience to people's lives, but have also caused some traffic accidents, among which accidents caused by drunk driving rank first.

[0038] Currently, the detection of drunk driving is mainly done by traffic police at places with heavy traffic or at intersections. This traditional method is inefficient and has limited detection capacity. Some drivers may take chances, which may lead to safety accidents. In order to reduce the occurrence of traffic accidents at the source, people have begun to study the vehicle drunk driving detection system. The existing drunk driving detection systems have the problems of single detection method, inaccurate detection or inconvenient use, so they have not been widely used.

[0039] Based on this, the present application proposes an intelligent drunk driving detection system, method and vehicle to improve the accuracy and convenience of the drunk driving detection system, thereby facilitating its promotion and application.

[0040] Hereinafter, one or more embodiments of the present application will be described in detail through specific examples.

[0041] This application provides an intelligent drunk driving detection system, such as Figure 1 As shown, the drunk driving intelligent detection system includes a controller, and a camera 1, an alcohol detector and a gear switch respectively connected to the controller;

[0042] The camera 1 and the alcohol detector are both embedded in the middle of the steering wheel of the vehicle, and are used to collect the driver's facial data and breath alcohol data respectively;

[0043] Wherein, the controller is used to control the gear switch to be in an on or off state according to the driver's facial data and breath alcohol data.

[0044] Specifically, the camera 1 and the alcohol detector are embedded in the middle of the steering wheel of the vehicle, and can be set close to the driver, which is convenient for the camera 1 to collect the driver's facial data and the alcohol detector to collect the driver's breath alcohol data, which is convenient for the driver. It can also prevent the camera 1 and the alcohol detector from rotating with the steering wheel, which is beneficial for the camera 1 and the alcohol detector to collect the corresponding data of the driver, thereby ensuring the stable operation of the drunk driving intelligent detection system.

[0045] Specifically, the controller is connected to the starting power supply of the vehicle. When the vehicle starts, the controller is awakened. The controller can drive the camera 1 and the alcohol detector to operate, and control the driver's facial data and breath alcohol data collected by the camera 1 and the alcohol detector to be sent to the controller. The controller judges and integrates the received driver's facial data and breath alcohol data to determine the state of the gear switch 3, thereby controlling the vehicle's driving state.

[0046] It should be noted that the camera 1 can simply take a picture of the driver's face and send it to the controller for face recognition to obtain the driver's face data, or the camera 1 can take a picture of the driver's face and then perform face recognition on its own to obtain the driver's face data and send it to the controller.

[0047] The alcohol detector can directly send the measured alcohol content value to the controller, or it can determine whether the driver has been drinking after measuring the alcohol content value and send the conclusion to the controller.

[0048] The controller can be a vehicle controller or an additional controller. The controller is connected to a sound output terminal (a speaker inside the vehicle, an external computer or tablet) to generate a corresponding prompt tone through the sound output terminal (a speaker inside the vehicle, an external computer or tablet). The prompt tone can be "Driver, please blow into the alcohol detector", "Driver, please shift gears normally", "Driver has been drinking and cannot shift gears", and "Facial information is incorrect. The vehicle gear will jump to P gear within 10 minutes. To ensure driving safety, please park the vehicle within 10 minutes", etc.

[0049] In this embodiment, a camera 1 and an alcohol tester 2 are embedded in the middle of the steering wheel of the vehicle and connected to the controller to obtain the driver's facial information and the driver's breath alcohol data, thereby facilitating confirmation of whether the driver is driving under the influence of alcohol. By setting the gear switch 3, the controller can control the driving state of the vehicle by controlling the gear switch 3. Based on the driver's facial data and the driver's breath alcohol data, it is confirmed whether the driver is driving under the influence of alcohol, and the facial data and breath alcohol data of the driver are combined, thereby avoiding the mismatch between the breath alcohol data and the facial data, which is conducive to ensuring the accuracy of the intelligent detection system for driving under the influence of alcohol, avoiding the occurrence of driving under the influence of alcohol from the source of the vehicle, and facilitating the promotion and application of the intelligent detection system for driving under the influence of alcohol.

[0050] In some embodiments, the drunk driving intelligent detection system further includes a seat belt sensor 4, which is located in a seat belt slot of the driver's seat and is connected to the controller.

[0051] Specifically, the seat belt sensor 4 is a sensor. When the driver's seat belt is fastened, that is, the driver's seat belt buckle is inserted into the driver's seat belt slot, the seat belt sensor 4 senses the seat belt buckle, that is, it is determined that the driver's seat belt is fastened. The seat belt sensor 4 sends the sensed information to the controller, and the controller can determine whether the driver's seat belt is fastened.

[0052] It should be noted that, when the seat belt buckle of the driver's seat is located in the seat belt slot of the driver's seat, the signal sensed by the seat belt sensor 4 is 1, and "1" is sent to the controller. When the controller receives the signal "1" sent by the seat belt sensor 4, it can be determined that the driver's seat belt is fastened; when the seat belt buckle of the driver's seat is outside the seat belt slot of the driver's seat, the signal sensed by the seat belt sensor 4 is "0", and "0" is sent to the controller. When the controller receives the signal "0" sent by the seat belt sensor 4, it can be determined that the driver's seat belt is not fastened.

[0053] In this embodiment, the seat belt sensor 4 is provided to facilitate the controller to obtain the state of the driver's seat belt to determine whether the driver's seat belt is fastened, so that the controller can control the state of the shift switch 3 based on the state of the driver's seat belt. The seat belt sensor 4 is a tool for the controller to obtain the driver's intention. When the driver's seat belt is fastened, it is determined that the driver's intention is to drive the vehicle.

[0054] In some embodiments, a mounting groove is provided in the middle of the steering wheel, and the camera 1 and the alcohol detector are integrated and installed in the mounting groove.

[0055] Specifically, the camera 1 and the alcohol detector are integrated and connected together in a horizontal or vertical row, the mounting groove is adapted to the outer size of the camera 1 and the alcohol detector after the integration, and the camera 1 and the alcohol detector are embedded in the middle of the steering wheel through the mounting groove.

[0056] In this embodiment, the setting of the installation groove can facilitate the integrated installation of the camera 1 and the alcohol detector, which is beneficial to the installation efficiency and promotion and application of the intelligent drunk driving detection system.

[0057] In some embodiments, the intelligent drunk driving detection system further includes a speedometer 5, which is located on the vehicle and connected to the controller.

[0058] Specifically, the speed meter 5 can be a radar speed meter 5 or a laser speed meter 5, which can be located at any position on the vehicle and set toward the front of the vehicle to accurately measure the speed of the vehicle.

[0059] In this embodiment, the setting of the speedometer 5 enables the controller to obtain the vehicle speed and further determine the driver's intention based on the vehicle speed to determine the state of the gear switch 3, thereby avoiding the situation where the vehicle replaces a drunk driver during driving, which is beneficial to the detection accuracy of the drunk driving intelligent detection system and avoids the occurrence of drunk driving accidents from the root.

[0060] Based on the same inventive concept, the present application also provides a drunk driving intelligent detection method, which is applied to the controller in the drunk driving intelligent detection system as described above, with reference to Figure 2 , the method comprising:

[0061] Step S100, in response to determining that the vehicle is started, obtaining the driver's face data through camera 1;

[0062] Specifically, the controller is connected to the starting power supply of the vehicle. When the vehicle starts, the controller is powered on and drives the camera 1 to operate to obtain the driver's facial data.

[0063] It should be noted that when the vehicle is in the starting state, the camera 1 continues to run to continuously obtain the driver's facial data, which can prevent the driver from cheating in collusion with others and is conducive to ensuring the accuracy of the drunk driving intelligent detection system.

[0064] In addition, when the vehicle is just started (or when the vehicle speed is zero), the controller controls the camera 1 to perform facial recognition on the driver (it can also control the camera 1 to cooperate with the controller to perform facial recognition to obtain the facial image required by the controller for facial recognition) to fully grasp the driver's facial data, which is beneficial for continuous facial matching of the driver during subsequent driving to avoid driver replacement.

[0065] When the controller controls the camera 1 to perform facial recognition on the driver, it also outputs information to the sound output terminal (tablet, computer or vehicle internal speaker) connected to the controller, so that the corresponding sound output terminal outputs a prompt sound "Please face the camera 1", prompting the driver to perform facial recognition.

[0066] Step S200, comparing the driver's facial data with a dataset of sober facial data;

[0067] Specifically, the controller compares the obtained driver's facial data with the facial data in the so-cold facial data set stored therein to determine whether the driver's facial data belongs to the so-cold facial data set.

[0068] It should be noted that the driver facial data may be the driver facial data obtained during facial recognition, or may be the driver facial data obtained by taking a picture of the driver's face in real time. The driver facial data obtained by taking a picture of the driver's face in real time is less than or equal to the driver facial data obtained during facial recognition, but it can be judged whether the driver facial data obtained by taking a picture of the driver's face in real time is the driver facial data obtained during facial recognition.

[0069] In addition, the sober face dataset is the faces of drivers who have been confirmed to be sober during the duration of the vehicle startup, which avoids repeated face recognition and alcohol testing due to driver changes, and is beneficial to the user's driving experience.

[0070] Step S300, in response to determining that the driver's face data is not included in the sober face data set, performing a breath alcohol test on the driver through an alcohol detector to obtain a test result;

[0071] Specifically, if the controller finds through comparison that the driver's facial data does not match the facial data in the so-not-drinking facial data set, that is, the driver's facial data is not included in the so-not-drinking facial data set, the alcohol detector is driven to perform a breath alcohol test on the driver to determine whether the driver has been drinking.

[0072] It should be noted that when the controller controls the operation of the alcohol detector, it also outputs information to the sound output end (tablet, computer or vehicle internal speaker) connected to the controller, so that the corresponding sound output end outputs a prompt sound of "Driver, please blow into the alcohol detector", prompting the driver to perform a breath alcohol test.

[0073] The alcohol detector can generate a test result of "drinking" or "not drinking", and can also generate a test result of breath alcohol content, and send it to the controller. The controller obtains the test result of "drinking" or "not drinking" based on the breath alcohol content.

[0074] For example, according to the current standards for identifying drunk driving, a driver is considered to have been drinking if the alcohol content in his blood is greater than or equal to 20 mg / 100 ml. When the alcohol detector measures the alcohol content in the driver's breath to be 20 mg / 100 ml, the controller generates a test result of "drinking"; when the alcohol detector measures the alcohol content in the driver's breath to be 20 mg / 100 ml, the alcohol detector generates a test result of "drinking" and sends it to the controller.

[0075] Step S400, in response to determining that the detection result is not drinking, the driver's facial data is stored in the not drinking facial data set, and the vehicle is controlled to be in a drivable driving state by controlling the gear switch 3 to be in an on state.

[0076] Specifically, if the controller obtains a breath alcohol test result of the driver that shows that he is not drunk, it determines that the driver corresponding to the test result is not drunk, and stores the driver's facial data in the non-drinking facial data set for use in the subsequent vehicle startup process to avoid repeated facial recognition and repeated alcohol detection. At the same time, the controller controls the gear switch 3 to be turned on, and the user can shift gears according to actual needs to drive the vehicle.

[0077] It should be noted that when the controller controls the gear switch 3 to be turned on, it also outputs information to the sound output end (tablet, computer or vehicle internal speaker) connected to the controller, so that the corresponding sound output end outputs a prompt sound of "Please driver shift gears and drive normally", prompting the driver to pass the test of the alcohol detection system and can drive the vehicle normally; when the controller controls the gear switch 3 to be turned off, the controller outputs information to the sound output end (tablet, computer or vehicle internal speaker) connected to the controller, so that the corresponding sound output end outputs a prompt sound of "The driver has drunk alcohol and cannot shift gears and drive", prompting the driver to be unable to drive the vehicle normally and need to be replaced.

[0078] In this embodiment, when the vehicle is in the starting state, the driver's facial data is obtained in real time through camera 1, and the driver's facial data is compared with the facial data in the so-called non-drinking facial data set. This can not only avoid affecting the driver's driving experience, but also avoid the situation where a drunk person pretends to be a so-drinking person to drive the vehicle, effectively avoid the occurrence of drunk driving, and thus help avoid the occurrence of drunk driving accidents, which is conducive to promotion and implementation.

[0079] In some embodiments, in step S100: before acquiring the driver's face data through camera 1, the following steps are included:

[0080] Step S101, obtaining the vehicle speed through the speed meter 5, and determining whether the driver's seat belt is fastened through the seat belt sensor 4;

[0081] Specifically, the speed meter 5 operates in real time to obtain the real-time vehicle speed, and sends the obtained vehicle speed to the controller, and the controller obtains the real-time vehicle speed through the speed meter 5;

[0082] Specifically, the controller obtains the state of the driver's seat belt through the real-time operation of the seat belt sensor 4, and then determines whether the driver's seat belt is fastened.

[0083] Step S102, in response to determining that the vehicle speed is zero and the driver's seat belt is not fastened, the vehicle is controlled to be in a non-drivable driving state by controlling the shift switch 3 to be in a closed state.

[0084] Specifically, when the controller determines that the vehicle speed is zero and the driver's seat belt is not fastened, that is, it determines that the driver has no driving intention, then the controller controls the shift switch 3 to be in a closed state, and the driver cannot shift gears, that is, the vehicle is in a non-drivable driving state, avoiding the situation where the driver's seat belt is not fastened and the vehicle is driven, which is not conducive to driving safety.

[0085] In this embodiment, the vehicle speed and the driver's seat belt status are respectively obtained by the speedometer 5 and the seat belt sensor 4 to determine whether the driver has the intention to drive. When the driver has no intention to drive, the subsequent step of obtaining the driver's facial data is not executed, and the alcohol detection step is not performed accordingly, so as to avoid wasting computing power.

[0086] It should be noted that when the vehicle is just started, the state of the gear switch 3 is closed by default, that is, the vehicle is in a non-driving state. When the vehicle speed is zero and the driver's seat belt is not fastened, the controller only needs to control the gear switch 3 to remain in the closed state.

[0087] The default state of the gear switch 3 is the closed state, which is also beneficial to the driving safety of the vehicle and avoids the situation of accidentally touching the gear.

[0088] In some embodiments, in step S100: before acquiring the driver's face data through camera 1, the method further includes:

[0089] Step S103, in response to determining that the vehicle speed is not zero, executing the step of acquiring the driver's face data through camera 1;

[0090] Specifically, when the controller determines that the vehicle speed is not zero, it means that the driver is driving the vehicle, so the controller controls the camera 1 to operate to obtain the driver's facial data in real time, so as to facilitate real-time comparison of the driver's facial data with the facial data in the non-drinking facial data set, avoid the situation where the driver is replaced, and help to improve the accuracy of the method.

[0091] Step S104 , in response to determining that the vehicle speed is zero and the driver's seat belt is fastened, a step of acquiring the driver's facial data through camera 1 is executed.

[0092] Specifically, when the controller determines that the vehicle speed is zero and the driver's seat belt is fastened, that is, confirms that the driver has the intention to drive, the controller controls camera 1 to obtain the driver's facial data. At this time, partial facial data of the driver can be obtained without facial recognition, and the obtained partial facial data of the driver is compared with the facial data in the so-not-drinking facial data set. If the comparison result is that the partial facial data of the driver does not belong to the so-not-drinking facial data set, the controller controls camera 1 to perform facial recognition to obtain all the driver's facial data; if the comparison result is that the partial facial data of the driver belongs to the so-not-drinking facial data set, the controller controls camera 1 to obtain partial facial data of the driver without facial recognition.

[0093] In this embodiment, the steps of acquiring the driver's facial data through the camera 1 are described in detail. Under different preconditions, the camera 1 acquires the driver's facial data in different ways. One is to acquire the driver's facial data through facial recognition, and the other is to acquire the driver's facial data through real-time photography. This can not only ensure the accuracy of the method, but also avoid the waste of computing power by repeated facial recognition, which is conducive to the promotion and application of the method.

[0094] In some embodiments, in step S300: the process of performing breath alcohol testing on the driver by using an alcohol detector, before obtaining the test result, includes:

[0095] Step S301, in response to determining that the vehicle speed is not zero and the driver's face data is not included in the sober face data set, the vehicle is controlled to be in an undriveable state after the preset time by controlling the gear switch 3 to be in an off state after the preset time;

[0096] When the gear switch 3 is in the off state, the gear position of the vehicle is P gear.

[0097] Specifically, when the vehicle speed is not zero and it is determined that the driver's facial data acquired in real time does not belong to the so-cold facial data set, the controller can determine that the driver has cheated in the drunk driving detection. Then, the gear switch 3 is controlled to be in a closed state after a preset time, that is, the gear of the vehicle jumps to P gear after a preset time, making the vehicle in an undriveable state, forcing the driver to stop the vehicle to avoid drunk driving.

[0098] Exemplarily, the preset time length may be 10 minutes. The preset time length cannot be too long or too short. It needs to ensure that the driver can park the vehicle safely and effectively avoid drunk driving.

[0099] It should be noted that when the controller controls the gear switch 3 to be in a closed state after a preset time, it also outputs information to the sound output end (tablet, computer or vehicle internal speaker) connected to the controller, so that the corresponding sound output end outputs a prompt tone of "The facial information is incorrect. The vehicle gear will jump to P gear within 10 minutes. To ensure driving safety, please park the vehicle within 10 minutes and accept facial recognition and alcohol testing." This prompts the driver to park the vehicle within the preset time and re-perform facial recognition and alcohol testing.

[0100] In some embodiments, the method further comprises:

[0101] Step S500, in response to determining that the vehicle is turned off, clearing the sober face dataset.

[0102] Specifically, when the controller determines that the vehicle is stalled, that is, the power of the driving controller is turned off, the controller clears the stored sober facial data set to avoid the sober facial data determined during the current vehicle startup process affecting the accuracy of the intelligent drunk driving detection of the driver when the vehicle is started next time, thereby improving the accuracy of the method and facilitating its promotion and application.

[0103] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
