[0033] On the other hand, embodiments of this application provide a vehicle for implementing any of the methods for preventing drunk driving described above.

[0034] The method for preventing drunk driving provided in this application is applied to an intelligent cockpit system. This system includes a controller, an image acquisition unit, a gas detection module, and an alert control module. The controller is electrically connected to the image acquisition unit, the gas detection module, and the alert control module. The method includes: the gas detection module sending the detected current alcohol concentration around the driver's seat to the controller. In response to the current alcohol concentration being higher than a preset alcohol concentration, the controller generates an image acquisition command and sends it to the image acquisition unit. In response to receiving the image acquisition command, the image acquisition unit acquires the facial features of the person in the driver's seat and sends them to the controller. In response to the facial features meeting a first preset condition, the controller activates the alert control module. The first preset condition indicates that the person is intoxicated. After activation, the alert control module keeps the vehicle in a parked state. In other words, this method can more accurately determine whether the person in the driver's seat is intoxicated based on the alcohol concentration around the driver's seat and the facial features of the person in the driver's seat. When the person in the driver's seat is intoxicated, the alert control module can be activated to keep the vehicle in a parked state. When a vehicle is parked, the driver is unable to continue driving, thus restraining the driver from driving under the influence of alcohol and preventing dangerous consequences caused by drunk driving.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0041] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] This application provides a method for preventing drunk driving. The method is applied to an intelligent cockpit system, which includes a controller, an image acquisition unit, a gas detection module, and an alert control module. The controller is electrically connected to the image acquisition unit, the gas detection module, and the alert control module. It should be noted that the controller can be a vehicle controller or a separate controller, such as a controller specifically designed to implement the drunk driving prevention method. The controller is capable of data processing, data storage, signal transmission, and command transmission.

[0043] This application provides a method for preventing drunk driving, which includes the following steps 101 to 105.

[0044] In step 101, the gas detection module sends the detected current alcohol concentration around the driver's seat to the controller.

[0045] It should be noted that, in this embodiment, the driver's seat refers to the driver's seat in a vehicle where the driver is seated. In some embodiments, the gas detection module includes an alcohol sensor, which is used to detect the current alcohol concentration around the driver's seat and is installed on the driver's seat. For example, the alcohol sensor can be installed in the headrest of the driver's seat. This avoids the alcohol concentration detection results being affected by the alcohol concentration of people in the rear seats or the front passenger seat. The alcohol sensor generally detects alcohol concentration within a limited range. For example, this detection range can be an area formed by the position of the alcohol sensor as the origin, extending 20-40 cm in front of the driver's seat, 5 cm to the left and right, and 5 cm behind the driver's seat. This allows for a more accurate determination of whether the person in the driver's seat is currently intoxicated.

[0046] In step 102, the controller, in response to the current alcohol concentration being higher than the preset alcohol concentration, generates an image acquisition command and sends the image acquisition command to the image acquisition device.

[0047] In some embodiments, the controller stores a preset alcohol concentration. This preset alcohol concentration can be lower than the legally mandated minimum concentration for drunk driving. In some embodiments, the image acquisition device is an image acquisition device with both conventional and infrared acquisition functions. The image acquisition device can be a camera.

[0048] In step 103, the image acquisition device responds to receiving the image acquisition command, acquires the facial features of the person in the driver's seat according to the image acquisition command, and sends the facial features to the controller.

[0049] In some embodiments, the image capture device is directed towards the driver's seat. For example, the image capture device may be directed towards the area where the face of the person in the driver's seat is located.

[0050] In step 104, the controller activates the reminder control module in response to the facial features meeting the first preset condition.

[0051] The first preset condition is used to indicate that the face is intoxicated.

[0052] In step 105, the reminder control module is activated to keep the vehicle in a parked state.

[0053] It should be noted that the parking state means the vehicle remains stationary and cannot move forward. While in the parking state, the vehicle can be started, but gear shifting is impossible; the gear can only be in Park (P). This ensures the control module can prevent the vehicle from performing normal driving maneuvers.

[0054] By employing the method for preventing drunk driving provided in this application, it is possible to accurately determine whether the person in the driver's seat is intoxicated based on the alcohol concentration around the driver's seat and the facial features of the person in the driver's seat. Furthermore, when the person in the driver's seat is intoxicated, the reminder control module can be activated to keep the vehicle in a parked state. Since the driver cannot continue driving in the parked state, this can restrain the driver's drunk driving behavior, avoid the dangerous consequences of drunk driving, and ensure the safety of the driver and others' lives and property.

[0055] This application also provides a method for preventing drunk driving. This method is applied to an intelligent cockpit system, which includes a controller, an image acquisition unit, a gas detection module, and an alert control module. The controller is electrically connected to the image acquisition unit, the gas detection module, and the alert control module. This controller is the same as the controller in the above embodiments and will not be described again here. The method for preventing drunk driving includes steps 201 to 208.

[0056] In step 201, the controller activates the gravity sensor in response to the vehicle being in the started state.

[0057] In some embodiments, the intelligent cockpit system also includes a gravity sensor electrically connected to the controller. The gravity sensor is typically installed inside the driver's seat, and the gravity value detected by the sensor reflects the weight of the load currently on the driver's seat. It should be noted that after the vehicle is started, all electrical components in the vehicle are powered on and can be used normally; for example, the occupant in the driver's seat can turn on the air conditioning and other devices to perform their respective functions.

[0058] In step 202, the gravity sensor detects the current load value of the driver's seat and sends the current load value to the controller.

[0059] In step 203, the controller starts the image acquisition unit and the gas detection module in response to the current load value being greater than the preset load value.

[0060] In some embodiments, the controller activates the image acquisition unit and the gas detection module in response to the current load value exceeding a preset load value and the vehicle being started. It should be noted that the preset load value is generally the minimum weight of an adult and can be pre-set and stored in the controller by a technician. Therefore, if the current load value exceeds the preset load value, it means that someone is currently sitting in the driver's seat. Setting the preset load value can prevent false alarms when other objects are placed in the driver's seat. For example, it avoids misjudging a situation where a computer or other objects are placed in the driver's seat. This avoids wasting processing resources and ensures the necessary activation of the image acquisition unit and the gas detection module.

[0061] In step 204, the gas detection module sends the detected current alcohol concentration around the driver's seat to the controller.

[0062] It should be noted that step 204 is the same as step 101, and will not be repeated here.

[0063] In step 205, the controller, in response to the current alcohol concentration being higher than the preset alcohol concentration, generates an image acquisition command and sends the image acquisition command to the image acquisition device.

[0064] It should be noted that step 205 is the same as step 102, and will not be repeated here.

[0065] In step 206, the image acquisition device responds to receiving the image acquisition command, acquires the facial features of the person in the driver's seat according to the image acquisition command, and sends the facial features to the controller.

[0066] It should be noted that step 206 is the same as step 103, and will not be repeated here.

[0067] In some embodiments, in response to receiving an image acquisition command, the image acquisition device acquires the driver's facial features by switching the acquisition mode from a normal acquisition mode to an infrared acquisition mode. The image acquisition device acquires a first facial image of the person in the driver's seat using the infrared acquisition mode and extracts facial features from the first facial image, including facial skin brightness. It should be noted that when a person is under the influence of alcohol, changes in blood flow and pulse rate occur, leading to alterations in skin brightness. Therefore, extracting facial skin brightness can more accurately determine whether the person in the driver's seat is intoxicated. It should also be noted that in normal acquisition mode, the image acquisition device acquires a second facial image of the person in the driver's seat; this second facial image is only used to represent the face of the person in the driver's seat.

[0068] In step 207, the controller activates the reminder control module in response to the facial features meeting the first preset condition.

[0069] The first preset condition is used to indicate that a person's face is intoxicated. It's understandable that, since the image acquisition device captures images of the driver's face, facial features can be used to further verify whether the high blood alcohol concentration originates from the driver. In other words, by combining the current blood alcohol concentration (higher than the preset concentration) with facial features, it's possible to more accurately determine whether the driver is intoxicated, avoiding misjudgments based on high blood alcohol concentrations from other non-driver personnel.

[0070] In some embodiments, the intelligent cockpit system further includes audio or video devices. After the reminder control module is activated, the method for preventing drunk driving further includes: the processor controlling the audio and / or video devices to play preset content. For example, the preset content may include the effects and dangers of drunk driving. This allows for timely reminders to the driver of the dangers of drunk driving, thus preventing the driver from engaging in drunk driving.

[0071] In some embodiments, the intelligent cockpit system includes a communication module. After the reminder control module is activated, the method for preventing drunk driving further includes: the communication module acquiring vehicle information, driver information, and preset information and sending them to a preset communication device. The preset information is a warning message about the dangers of drunk driving. It should be noted that the vehicle information includes basic vehicle information, such as license plate number and vehicle model, and may also include the vehicle's current location information. In some embodiments, the intelligent cockpit system also includes a positioning module, which sends the acquired vehicle's current location information to the communication module. The driver information includes an image of the person in the driver's seat and the person's current blood alcohol concentration, information that can represent the driver's identity and state of intoxication. The preset communication device can be a mobile phone, computer, or other communication device belonging to the vehicle owner, their family, or a friend. This method can promptly remind the vehicle owner, family, or friends that the driver is currently intoxicated, avoiding dangerous consequences due to drunk driving. At the same time, it can also prevent situations where car owners lend their cars to others and those people drive under the influence of alcohol, which could affect the car owners themselves. In other words, after the car owner's preset communication device receives the information, it can promptly stop the drunk driving behavior and avoid the dangerous consequences caused by drunk driving.

[0072] In step 208, the reminder control module is activated to keep the vehicle in a parked state.

[0073] In some embodiments, the reminder control module is electrically connected to the vehicle's transmission or the vehicle's power unit controller. It is understood that when the transmission is operating normally, the vehicle can shift gears and move forward. When the transmission is locked, the vehicle cannot shift gears and can only remain stationary. The power unit controller controls the vehicle's power units. When the power unit controller is active, it can control the various power units of the vehicle to enable normal forward movement. When the power unit controller is inactive, it cannot transmit signals or commands, thus preventing the power units from operating and causing the vehicle to remain stationary.

[0074] In some embodiments, after the controller activates the reminder control module, the method further includes: the reminder control module locking the transmission; or, the reminder control module controlling the power unit controller to be in a non-operating state. This allows the vehicle to remain parked, effectively deterring drunk driving and preventing dangerous consequences.

[0075] In some embodiments, the intelligent cockpit system further includes a scheme budgeting module and a communication module, which are electrically connected to the controller. The method for preventing drunk driving provided in this application also includes the following three steps:

[0076] The first step is for the communication module to obtain travel information and send it to the plan budget module.

[0077] The second step involves the solution budgeting module identifying at least one candidate solution based on travel information and sending it to the controller. These candidate solutions include alternatives to driving under the influence, such as hotel accommodation, designated driver services, and taxis, along with their corresponding budget prices. Travel information can include the travel location, travel time, and route. For example, travel information might include the vehicle's current location, nearby hotels, and the route and time from the vehicle's current location to its frequently visited locations. The solution budgeting module can obtain hotel prices, taxi fares, or designated driver prices for different travel information from the internet and calculate at least one candidate solution. Furthermore, multiple candidate solutions can be sorted by price from lowest to highest or by time from shortest to longest, providing drivers with better alternatives to prevent drunk driving.

[0078] Third, the controller sends at least one candidate solution to the vehicle's display screen for display. In some embodiments, each candidate solution corresponds to a selection item, and in response to the driver's triggering operation on the selection item, the candidate solution selected by the driver is taken as the final target solution.

[0079] In some embodiments, the intelligent cockpit system further includes a storage module electrically connected to the image acquisition unit. The method for preventing drunk driving provided in this application further includes: the image acquisition unit sending acquired images to the storage module, and the storage module storing the images. It should be noted that the images stored in the storage module can provide evidence of drunk driving by the driver, to determine the true identity and actual condition of the person committing drunk driving. The images acquired by the image acquisition unit include images acquired in normal mode and images acquired in infrared mode.

[0080] In some embodiments, the intelligent cockpit system further includes an emergency drive module. The method for preventing drunk driving provided in this application further includes: the emergency drive module generating an unlock signal in response to a driver's triggering operation, and sending the unlock signal to an alert control module. The alert control module, in response to the unlock signal, switches the vehicle from a parked state to a non-parked state. It should be noted that the driver can drive the vehicle in situations requiring emergency avoidance, thereby preventing serious consequences for the driver or others' life and property. In some embodiments, the alert control module, in response to the unlock signal, controls the transmission to switch from a locked state to an unlocked state, or controls the power unit controller to switch from a non-operating state to an operating state, thereby allowing the vehicle to be in a non-parked state and move normally under the driver's operation.

[0081] In some embodiments, after the alert control module switches the vehicle to an unparked state, the communication module acquires vehicle information, vehicle location information, an image of the person in the driver's seat, and the current blood alcohol concentration of the person in the driver's seat, and sends the acquired information to designated communication devices. These designated communication devices include those for the vehicle owner, their family or friends, and traffic police. This provides strong evidence for subsequent accountability procedures and helps prevent misjudgments.

[0082] In some embodiments, in response to the current load value being less than a preset load value and the vehicle being off, the controller switches the gas detection module from the activated state to the deactivated state and controls the reminder control module to restore the transmission and power control unit controllers to their initial states. It should be noted that the initial state of the transmission is an unlocked state, and the initial state of the power control unit controller is a normal operating state. This allows the vehicle to be promptly restored to a controllable state when the driver abandons their drunk driving behavior, enabling the driver to drive the vehicle normally again when not intoxicated.

[0083] In some embodiments, in response to a current load value being less than a preset load value and the vehicle being in an ignition state, the controller keeps the gas detection module active and controls the reminder control module to keep the vehicle in a parked state. This can prevent drivers who have not yet refrained from driving under the influence from engaging in drunk driving.

[0084] Understandably, once the vehicle is restarted, each step of the method for preventing drunk driving provided in the embodiments of this application will be repeated.

[0085] By adopting the method for preventing drunk driving provided in the embodiments of this application, not only can the drunk driving behavior of drivers be restrained in a timely manner, but it can also provide timely warnings to drivers or other relevant personnel, thereby better preventing drunk driving.

[0086] This application also provides a vehicle for implementing the method for preventing drunk driving described in any of the embodiments of this application. This not only prevents drivers from driving under the influence of alcohol, but also avoids repair costs caused by damage to the vehicle due to drunk driving. In other words, it ensures the personal safety of the driver and others, and also protects their property.

[0087] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0088] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.
