Description

Technical Field

[0001] This application relates to the field of safe driving technology, and in particular to a vehicle control method, device, electronic device, and computer-readable storage medium. Background Technology

[0002] The World Health Organization states that drunk driving is the leading cause of 50% to 60% of traffic accidents and a major cause of traffic fatalities. Drunk driving accidents not only inflict irreversible harm on victims and their families but also impose a significant burden on society and the economy. Despite strengthened national laws and regulations, drunk driving accidents are still 100% preventable. Therefore, automakers need to equip vehicles with auxiliary measures and proactively intervene through technological means to reduce drunk driving accidents and improve road safety.

[0003] However, existing driver condition monitoring and vehicle control systems have several shortcomings. First, single detection methods cannot comprehensively assess driver condition and may overlook risk factors such as fatigue or sudden health problems. Second, they lack tiered control strategies and often resort to one-size-fits-all measures (such as direct disabling of starting or forced stopping), which lack flexibility and may inconvenience the driver. Furthermore, some systems lack real-time feedback and emergency response mechanisms after anomaly detection, making it difficult to obtain necessary assistance in critical moments. Summary of the Invention

Detailed Implementation

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The vehicle control method, apparatus, electronic device, and computer-readable storage medium of the present application embodiments are described in detail below with reference to the accompanying drawings.

[0025] This application provides a vehicle control method, wherein the vehicle includes an alcohol concentration detection device, a heart rate detection device, and a user status detection device.

[0026] In some embodiments of this application, the alcohol concentration detection device is located at the upper center of the steering wheel, the heart rate detection device is located at the center of both sides of the steering wheel, and the user status detection device is located on the A-pillar guard plate and the plastic cover plate on the upper edge of the windshield. The user status detection device includes a camera.

[0027] Reference Figure 1 The schematic diagram shown illustrates the installation locations. The alcohol concentration detector, heart rate detector, and driver status detection device are each installed in specific locations within the vehicle to achieve comprehensive monitoring of the driver's condition. The alcohol concentration detector can be installed at the upper center of the steering wheel (e.g.,...). Figure 1 As shown in position 1, the system can directly detect the alcohol concentration in the driver's breath, thereby determining whether the driver has been drinking and the degree of alcohol consumption. Heart rate monitoring devices are located at the center of each side of the steering wheel (e.g., at position 1). Figure 1(As shown in position 2), the system can monitor the driver's heart rate in real time while their hands are on the steering wheel, serving as an important basis for assessing the driver's physical health and mental state. The user status detection device includes cameras, mounted on the A-pillar trim and a plastic cover along the upper edge of the windshield (e.g., ...). Figure 1 (As shown in position 3), by monitoring the driver's facial expressions, eye movements, and other behavioral characteristics in real time, the system further assists in determining whether the driver is suspected of driving under the influence of alcohol. The reasonable layout of these devices ensures comprehensive monitoring of the driver's condition, providing accurate data support for subsequent vehicle control strategies.

[0028] The data signals collected by each detection device through its internal sensors are transmitted synchronously to the vehicle controller. For example... Figure 2 As shown, the alcohol concentration detection device transmits the detected alcohol concentration signal, the heart rate detection device transmits the heart rate data signal, and the user status detection device transmits the image signal captured by the camera to the vehicle controller. The vehicle controller then comprehensively processes and analyzes these signals. The vehicle controller can accurately judge the driver's state and implement corresponding vehicle control strategies based on the judgment results.

[0029] This application embodiment achieves comprehensive, multi-dimensional monitoring of the driver's state by rationally arranging alcohol concentration detection devices, heart rate detection devices, and user status detection devices inside the vehicle and synchronously transmitting the data signals collected by these devices to the vehicle controller for integrated processing and analysis. This multi-sensor fusion monitoring method not only improves the accuracy of detecting the driver's drinking status but also, with the assistance of heart rate and behavioral characteristics, more accurately assesses the driver's physiological and mental state. Based on this comprehensive data, the vehicle controller implements corresponding vehicle control strategies, effectively preventing drunk driving, reducing traffic accidents caused by drunk driving at the source, and improving road safety. Furthermore, this integrated monitoring system design does not cause additional interference to the vehicle's interior space or the driver's normal driving operations, and possesses good versatility and scalability, making it widely applicable to different vehicle models and providing strong technical support for safe driving.

[0030] Figure 3 This is a flowchart of a vehicle control method according to some embodiments of this application. (Refer to...) Figure 3 Vehicle control methods may include: S1, obtain the alcohol concentration of the user's exhaled breath through an alcohol concentration detection device, obtain the user's heart rate through a heart rate detection device, and obtain the user's first state information through a user state detection device.

[0031] The first state information refers to various physiological and behavioral characteristics of the driver obtained through the user state detection device. For example, the first state information may include the driver's facial expressions, eye contact, head movements, and other behavioral characteristics related to driving behavior. The first state information can reflect the driver's level of concentration, fatigue level, whether they are in an abnormal state (such as abnormal behavior after intoxication), and other factors that may affect driving safety.

[0032] Specifically, by using an alcohol concentration detection device to obtain the alcohol concentration in the user's breath, it is possible to directly determine whether the driver has been drinking and the degree of alcohol consumption. A heart rate detector to obtain the user's heart rate can reflect the driver's physiological state and level of mental stress. The primary state information obtained through the user state detection device includes the driver's facial expressions, eye contact, head movements, and other behavioral characteristics related to driving. All of this information, when combined, provides the vehicle controller with comprehensive driver state data, laying a solid data foundation for more accurate assessments of the driver's suitability for driving and the implementation of corresponding vehicle control strategies.

[0033] S2, obtain the current status information of the vehicle.

[0034] The vehicle's current status information includes its speed, engine speed, gear position, braking status, steering angle, vehicle position, fault codes, and other real-time data related to vehicle operation. This current status information reflects the vehicle's current operating condition and driving environment, providing crucial information for subsequent vehicle control strategies.

[0035] Specifically, information such as vehicle speed, engine speed, vehicle location, vehicle fault codes, and other current status information related to vehicle operation can be obtained from vehicle controllers, sensor systems, in-vehicle network systems, and vehicle networking systems.

[0036] S3 controls the vehicle based on the current status information and the first status information, as well as the alcohol concentration and / or heart rate.

[0037] Specifically, based on the vehicle's current status information (such as driving speed, engine speed, braking status, etc.), the driver's initial status information (such as facial expressions, eye state, head movements, and other behavioral characteristics), and alcohol concentration and / or heart rate data, the vehicle control system can comprehensively determine whether the driver is suitable to continue driving the vehicle and implement corresponding control strategies accordingly.

[0038] In some embodiments of this application, vehicle control is performed based on current status information and first status information, as well as alcohol concentration and / or heart rate, including: in response to the current status information indicating that the vehicle is in an inactive state, if the alcohol concentration is greater than or equal to a first preset alcohol concentration, then vehicle start-up is prohibited; if the alcohol concentration is greater than a second preset alcohol concentration but less than the first preset alcohol concentration, then the maximum driving speed of the current driving road is obtained, and an upper limit driving speed of the vehicle is determined based on the maximum driving speed and a preset speed percentage, and the current driving speed of the vehicle is controlled to be less than the upper limit driving speed, wherein the first preset alcohol concentration is greater than the second preset alcohol concentration; if the first status information meets a first preset reminder condition, then the vehicle is controlled to perform relevant reminder operations on the user.

[0039] The first preset alcohol concentration refers to the alcohol concentration threshold used to determine whether a driver is intoxicated and unfit to drive. The first preset alcohol concentration can be set by relevant technical personnel according to actual conditions. For example, the first preset alcohol concentration can be set to 20 mg / 100 ml.

[0040] If the current status information indicates that the vehicle is not started, and the alcohol concentration is greater than or equal to the first preset alcohol concentration, then starting the vehicle is prohibited.

[0041] Specifically, when the vehicle controller determines from the current status information that the vehicle is not started, if the detected blood alcohol concentration is greater than or equal to a first preset blood alcohol concentration (e.g., 20mg / 100ml), the vehicle controller will determine that the driver has a high level of alcohol consumption and poses a high risk of drunk driving. At this time, the vehicle controller will execute a command to prevent the vehicle from starting, ensuring that the driver cannot start the vehicle while intoxicated, thereby effectively preventing drunk driving and ensuring road safety.

[0042] Furthermore, the second preset alcohol concentration refers to a lower alcohol concentration threshold used to determine that although the driver has not reached a state of intoxication, there is still a certain risk of alcohol consumption. The second preset alcohol concentration can be set by relevant technical personnel according to the actual situation. For example, the second preset alcohol concentration can be set to 0mg / 100ml. The first preset alcohol concentration is greater than the second preset alcohol concentration.

[0043] A preset speed percentage refers to a speed ratio set based on the maximum speed limit of the current road when the vehicle is permitted to start but its speed must be limited. The preset speed percentage can be set by relevant technical personnel according to actual conditions. For example, if the preset speed percentage is 80%, the vehicle's maximum speed limit will be set to 80% of the maximum speed limit of the road.

[0044] If the alcohol concentration is greater than the second preset alcohol concentration but less than the first preset alcohol concentration, the maximum driving speed of the current driving road is obtained, and the upper limit driving speed of the vehicle is determined based on the maximum driving speed and the preset speed percentage, and the current driving speed of the vehicle is controlled to be less than the upper limit driving speed.

[0045] Specifically, when the alcohol concentration detected by the alcohol concentration detection device is greater than a second preset alcohol concentration (e.g., 0 mg / 100 ml) and less than a first preset alcohol concentration (e.g., 20 mg / 100 ml), the vehicle controller first obtains the maximum permissible speed of the current road through the vehicle's navigation system or vehicle-to-everything (V2X) function. Then, based on a preset speed percentage (e.g., 80%), the vehicle's upper limit speed is calculated. For example, if the maximum permissible speed on the current road is 100 km / h and the preset speed percentage is 80%, the vehicle's upper limit speed will be set to 80 km / h. The vehicle controller then controls the vehicle according to this upper limit speed.

[0046] The first preset warning condition refers to a specific condition set based on the driver's initial state information (such as facial expressions, eye contact, head movements, and other behavioral characteristics) to determine whether the driver is in an unsuitable driving state. The first preset warning condition can be set by relevant technical personnel according to actual circumstances. For example, the first preset warning condition can be set to indicate that the driver's facial expressions showing fatigue or drowsiness, unfocused eyes or frequent eye closure, or other driving-related behavioral characteristics suggest that the driver may be in an unsuitable driving state.

[0047] If the first status information meets the first preset reminder condition, then control the vehicle to perform relevant reminder operations on the user.

[0048] Specifically, when the vehicle controller detects that the driver's first state information meets one or more of the aforementioned first preset reminder conditions, it will determine that the driver may be in an unsuitable driving state, thereby triggering the vehicle to perform relevant reminder operations to the user. For example, voice prompts, seat vibration, flashing dashboard warning lights, etc., to remind the driver to pay attention to rest or take other safety measures, thereby effectively reducing the risk of traffic accidents caused by fatigue driving or other abnormal states.

[0049] As a specific embodiment of this example, please refer to the following: Figure 4 The vehicle control method of this application may include: S401, vehicle not started.

[0050] S402, determine whether the alcohol concentration is greater than the first preset alcohol concentration: if so, proceed to S403, otherwise proceed to S404.

[0051] S403, vehicle start prohibited.

[0052] S404, determine whether the alcohol concentration is greater than the second preset alcohol concentration and less than the first preset alcohol concentration: if so, execute S405, otherwise execute S406.

[0053] S405, executes speed limit control.

[0054] S406, determine whether the first status information meets the first preset reminder condition: if yes, execute S407, otherwise execute S408.

[0055] S407 controls the vehicle to provide relevant reminders to the user.

[0056] S408, the vehicle can be started normally.

[0057] In some embodiments of this application, after controlling the current driving speed of the vehicle to be less than the upper limit driving speed, the vehicle control method further includes: obtaining the current driving status information of the vehicle, and sending the current driving status information and alcohol concentration to the target terminal.

[0058] Specifically, after controlling the vehicle's current speed to be lower than the maximum speed limit, the vehicle control system will further acquire information about the vehicle's current driving status. Subsequently, the vehicle controller will send this current driving status information, along with the previously detected alcohol concentration data, to a preset target terminal via the vehicle's communication equipment (such as 4G / 5G networks, Wi-Fi, or V2X communication technology).

[0059] It should be noted that the target terminal can be the vehicle's management platform, the mobile device of an emergency contact (such as the driver's family or friends), or the vehicle manufacturer's monitoring center. Sending current driving status information and alcohol concentration to the target terminal is to provide real-time feedback on the driving status, so that relevant parties can promptly understand the driver's drinking status and the vehicle's driving status, thereby taking further necessary measures, such as providing remote assistance, arranging a designated driver, or notifying relevant departments, to ensure driving safety and road safety.

[0060] In some embodiments of this application, the vehicle is controlled based on current status information and first status information, as well as alcohol concentration and / or heart rate. The vehicle control method further includes: in response to the current status information indicating that the vehicle is in an inactive state, if the heart rate is greater than or equal to a first preset heart rate threshold, or the alcohol concentration is greater than or equal to a third preset alcohol concentration, then controlling the vehicle to contact the user's emergency contact and simultaneously controlling the vehicle to perform related alarm operations, wherein the third preset alcohol concentration is greater than the first preset alcohol concentration; if the first status information meets preset alarm conditions, and the heart rate is less than the first preset heart rate threshold and greater than or equal to a second preset heart rate threshold, then controlling the vehicle to contact the user's emergency contact and simultaneously controlling the vehicle to perform related alarm operations, wherein the first preset heart rate threshold is greater than the second preset heart rate threshold.

[0061] The first preset heart rate threshold is a specific heart rate value used to determine whether the driver has any physiological abnormalities that may seriously affect driving safety or even endanger their life. When the detected heart rate is greater than or equal to the first preset heart rate threshold, the vehicle controller will consider the driver's physiological state unsuitable for driving.

[0062] The third preset alcohol concentration refers to a higher alcohol concentration threshold used to determine whether the driver is severely intoxicated; its value is greater than the first preset alcohol concentration. When the detected alcohol concentration is greater than or equal to the third preset alcohol concentration, the vehicle controller will consider the driver's level of intoxication to be extremely serious, posing a very high driving risk and a direct threat to life safety. The third preset alcohol concentration is greater than the first preset alcohol concentration. The first preset heart rate threshold and the third preset alcohol concentration can be set by technicians according to actual conditions.

[0063] In response to the current status information indicating that the vehicle is not started, if the heart rate is greater than or equal to the first preset heart rate threshold, or the alcohol concentration is greater than or equal to the third preset alcohol concentration, the vehicle will be controlled to contact the user's emergency contact and perform relevant alarm operations. The third preset alcohol concentration is greater than the first preset alcohol concentration.

[0064] Specifically, when the vehicle controller determines from the current status information that the vehicle is not started, if it detects that the driver's heart rate is greater than or equal to a first preset heart rate threshold, or that the blood alcohol concentration is greater than or equal to a third preset blood alcohol concentration, the vehicle control system will take more stringent measures. On one hand, the vehicle controller will automatically contact the user's pre-set emergency contacts, such as the driver's family, friends, or designated rescue organizations, to inform them of the driver's current condition so that timely assistance can be provided. On the other hand, the vehicle will perform relevant alarm operations, such as emitting an alarm sound and flashing warning lights, to attract the attention of those around and remind the driver to take appropriate measures. This dual-measure approach aims to ensure that when the driver is in a state unsuitable for driving, they can obtain necessary help and support in a timely manner, thereby effectively preventing potential traffic accidents and ensuring driving and road safety.

[0065] Furthermore, preset alarm conditions refer to specific conditions set based on the driver's initial state information (such as facial expressions, eye contact, head movements, and other behavioral characteristics) to determine whether the driver is in an abnormal state or has potential driving risks. These conditions are usually related to the driver's level of concentration, fatigue, abnormal behavior, or other factors that may affect driving safety. For example, a driver's facial expression indicating extreme fatigue, a vacant stare or frequent eye closure, or abnormal head movements may all trigger preset alarm conditions. The second preset heart rate threshold is a lower heart rate value used to determine whether the driver has mild physiological abnormalities or a state of mental stress. This second preset heart rate threshold is lower than the first preset heart rate threshold and is used to distinguish between different degrees of physiological states. When the heart rate is lower than the first preset heart rate threshold but greater than or equal to the second preset heart rate threshold, the system considers that the driver may have a mild discomfort state, but still requires attention.

[0066] It is understandable that the preset alarm conditions and the second preset heart rate threshold can be set by technicians according to the actual situation, and there are no specific restrictions.

[0067] If the first status information meets the preset alarm conditions, and the heart rate is less than the first preset heart rate threshold and greater than or equal to the second preset heart rate threshold, then the vehicle is controlled to contact the user's emergency contact and simultaneously perform the relevant alarm operation.

[0068] Specifically, when the first status information meets the preset alarm conditions (indicating that the driver may be in an abnormal state), and the heart rate is less than the first preset heart rate threshold but greater than or equal to the second preset heart rate threshold, the vehicle control system will determine that the driver is in a state requiring attention. At this time, the vehicle controller will automatically notify the user's pre-set emergency contacts, such as the driver's family, friends, or designated rescue organizations, to inform them of the driver's current status. Simultaneously, the system will trigger the vehicle's alarm system, such as emitting an alarm sound and flashing warning lights, to attract the attention of those around and remind the driver to take appropriate measures.

[0069] In some embodiments of this application, the vehicle is controlled based on the current state information and the first state information, as well as the alcohol concentration and / or heart rate. The vehicle control method further includes: responding to the current state information indicating that the vehicle is in a running state and the vehicle speed is zero, if the alcohol concentration is greater than or equal to a first preset alcohol concentration, then controlling the vehicle to stop; if the heart rate is greater than or equal to a first preset heart rate threshold, or the alcohol concentration is greater than or equal to a third preset alcohol concentration, then controlling the vehicle to stop, and controlling the vehicle to contact the user's emergency contact while simultaneously controlling the vehicle to perform related alarm operations; if the first state information meets preset alarm conditions, and the heart rate is less than the first preset heart rate threshold and greater than or equal to a second preset heart rate threshold, then controlling the vehicle to stop, and controlling the vehicle to contact the user's emergency contact while simultaneously controlling the vehicle to perform related alarm operations.

[0070] Specifically, when the vehicle is running but at zero speed, the vehicle controller will take appropriate safety control measures based on the currently detected blood alcohol concentration, heart rate, and the driver's initial state information. If the detected blood alcohol concentration is greater than or equal to a first preset blood alcohol concentration, the vehicle controller will shut down the vehicle to prevent the driver from continuing to drive while intoxicated. If the heart rate is greater than or equal to a first preset heart rate threshold, or the blood alcohol concentration is higher and reaches or exceeds a third preset blood alcohol concentration, or if the driver's initial state information meets preset alarm conditions and the heart rate is lower than the first preset heart rate threshold but higher than or equal to a second preset heart rate threshold, the vehicle controller will comprehensively determine that the driver is in a highly dangerous or attention-required state. The vehicle controller will not only shut down the vehicle but will also automatically contact the user's emergency contact and trigger the vehicle's alarm system, such as emitting an alarm sound and flashing warning lights, to attract the attention of those around and remind the driver to take appropriate measures.

[0071] In some embodiments of this application, the vehicle is controlled based on the current state information and the first state information, as well as the alcohol concentration and / or heart rate. The vehicle control method further includes: in response to the current state information indicating that the vehicle is in motion, if the alcohol concentration is greater than or equal to a first preset alcohol concentration, controlling the vehicle to remind the user to pull over; if the alcohol concentration is greater than a second preset alcohol concentration but less than the first preset alcohol concentration, controlling the vehicle's current driving speed to be less than the upper limit driving speed; if the heart rate is greater than or equal to a first preset heart rate threshold, or the alcohol concentration is greater than or equal to a third preset alcohol concentration, controlling the vehicle to contact the user's emergency contact, simultaneously controlling the vehicle to remind the user to pull over, and controlling the vehicle to perform relevant alarm operations after parking.

[0072] Specifically, when the vehicle is in motion, if the vehicle controller detects an alcohol concentration greater than or equal to a first preset alcohol concentration, it will remind the driver to pull over to avoid safety hazards caused by drunk driving. If the alcohol concentration is between a second preset alcohol concentration and the first preset alcohol concentration, the vehicle controller will automatically limit the vehicle's speed to below a preset upper limit to reduce driving risks. Furthermore, when the heart rate is greater than or equal to a first preset heart rate threshold, or the alcohol concentration reaches or exceeds a third preset alcohol concentration, the vehicle controller will automatically contact the user's emergency contact and remind the driver to pull over. After the vehicle is safely parked, the vehicle controller will also trigger alarm operations, such as emitting an alarm sound or flashing warning lights, to attract the attention of those around and remind the driver to take further action.

[0073] The vehicle control method proposed in this application acquires the driver's alcohol concentration, heart rate, facial expression, and eye state information in real time through an alcohol concentration detection device, a heart rate detection device, and a user state detection device, and combines this information with the vehicle's current state information (such as driving speed and engine speed). A tiered control strategy is then adopted based on different driving scenarios.
