Description

Technical Field

[0001] This application relates to the field of intelligent driving, and more specifically, to a method for indicating the driving status of a vehicle, an electronic device, and a vehicle. Background Technology

[0002] As the level of automotive intelligence continues to improve, vehicles equipped with intelligent driving functions are becoming increasingly common, and these functions are being used more and more extensively in operational scenarios. During the operation of the intelligent driving system, the vehicle will use dashboard icons to indicate its intelligent driving status.

[0003] However, existing technologies for indicating the status of intelligent driving have significant shortcomings. Status information mainly relies on dashboard icons or scattered, independent warning devices, lacking a unified and authoritative status identifier for all occupants. Drivers need to actively shift their gaze and interpret the icons, making the prompts unintuitive. When fatigued or distracted, drivers are prone to missing status transition warnings, leading to delayed takeover. Simultaneously, passengers have no way of knowing whether the vehicle is currently being driven by the system or manually, resulting in a lack of anticipation regarding vehicle behavior and potentially causing confusion, anxiety, and distrust. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a method, electronic device, and vehicle for indicating vehicle driving status. This method enhances the driver's perception efficiency of changes in intelligent driving status through intuitive status prompts, reduces the risk of the driver missing handover prompts, and simultaneously improves passengers' awareness of the vehicle's intelligent driving status, thereby increasing passengers' perception and trust in intelligent driving behavior.

[0021] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by the present invention to achieve its intended purpose. However, the accompanying drawings are for reference and illustration only and are not intended to limit the present invention.

[0022] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] Figure 1 This is a flowchart of a vehicle driving status prompting method according to the first embodiment of the present invention.

[0024] like Figure 1 As shown, the vehicle driving status prompting method provided in this embodiment includes the following steps: Step S11: Obtain vehicle driving status signals.

[0025] Specifically, when the vehicle is powered on, the ADCU (Autonomous Driving Control Unit) sends vehicle driving status signals to the CDC (Cockpit Domain Controller) or a dedicated intelligent driving status coordination controller. The CDC or intelligent driving status coordination controller receives the vehicle driving status signals sent by the ADCU. These signals include at least one of the following intelligent driving states: intelligent driving inactive or activated, intelligent driving degraded, requesting takeover, high collision risk, or serious malfunction.

[0026] Vehicle driving status signals are used to characterize the different intelligent driving scenarios currently in which the intelligent driving system is located. For example, the vehicle driving status signals acquired by the ADCU in different intelligent driving scenarios are shown below: When the vehicle's intelligent driving function is not activated, the vehicle driving status signals acquired by the ADCU include the intelligent driving function not being activated.

[0027] When the vehicle's intelligent driving function is activated, the ADCU acquires vehicle driving status signals including the intelligent driving activation status.

[0028] When the vehicle's intelligent driving function is activated, and the intelligent driving system's perception or function is limited, but the intelligent driving system has not yet requested immediate takeover, the vehicle driving status signals acquired by the ADCU include intelligent driving activation status and intelligent driving degraded status.

[0029] When the vehicle's intelligent driving function is activated and the intelligent driving system requests the driver to take over immediately, the vehicle driving status signals acquired by the ADCU include the intelligent driving activation status and the request for takeover status.

[0030] When the vehicle's intelligent driving function is activated, and the intelligent driving system experiences a serious malfunction and / or a very high collision risk, the vehicle driving status signals acquired by the ADCU include the intelligent driving activation status, as well as the high collision risk status and / or serious malfunction status.

[0031] Step S12: Obtain the warning level based on the vehicle driving status signal.

[0032] Specifically, the CDC or intelligent driving status coordination controller obtains the prompt level based on the vehicle driving status signal and preset mapping rules.

[0033] like Figure 2 As shown, the steps of the method for obtaining the prompt level based on vehicle driving state signals and preset mapping rules include: Step S21: Based on the vehicle driving status signal and the preset mapping rule, obtain at least one candidate prompt level.

[0034] Specifically, when the vehicle driving status signal includes an inactive state, the acquired candidate prompt level includes a first candidate prompt level; or, when the vehicle driving status signal includes an intelligent driving activated state, the acquired candidate prompt level includes a second candidate prompt level; when the vehicle driving status signal includes an intelligent driving degraded state, the acquired candidate prompt level includes a third candidate prompt level; when the vehicle driving status signal includes a takeover request state, the acquired candidate prompt level includes a fourth candidate prompt level; and when the vehicle driving status signal includes a high collision risk state and / or a serious malfunction state, the acquired candidate prompt level includes a fifth candidate prompt level. Each state in the vehicle driving status signal has a corresponding candidate prompt level.

[0035] Step S22: Determine whether the number of candidate prompt levels is greater than the preset number.

[0036] Specifically, when the number of candidate prompt levels is not greater than a preset number (usually 1, which can be adjusted based on received setting information), proceed to step S23: obtain the prompt level based on the candidate prompt levels; when the number of candidate prompt levels is greater than the preset number, proceed to step S24: obtain the prompt level based on the priority of the multiple candidate prompt levels. The prompt level is any one of the first prompt level, second prompt level, third prompt level, fourth prompt level, and fifth prompt level. The number of prompt levels is consistent with the number of candidate prompt levels.

[0037] Specifically, when the number of candidate prompt levels is not greater than a preset number, the prompt level is obtained based on the level corresponding to the candidate prompt level. For example, when the number of candidate prompt levels is 1 and the candidate prompt level is the third candidate prompt level, the obtained prompt level is the third prompt level. The prompt level obtained is the same as the candidate prompt level.

[0038] Specifically, when the number of candidate suggestion levels exceeds a preset number, the multiple candidate suggestion levels are sorted according to priority. The candidate suggestion level with the highest sorting priority is obtained, and the corresponding suggestion level is obtained based on the level of this highest priority candidate suggestion level. For example, when there are two candidate suggestion levels, including a second and a third candidate suggestion level, the two candidate suggestion levels are sorted in the order of third and second. The third candidate suggestion level, with the higher sorting order, is set as the highest priority candidate suggestion level. The suggestion level obtained based on the highest priority candidate suggestion level (in this example, the third suggestion level) is the same as the highest priority candidate suggestion level. The priority of the candidate suggestion levels is: fifth candidate suggestion level > fourth candidate suggestion level > third candidate suggestion level > second candidate suggestion level > first candidate suggestion level. The higher the level value of the candidate suggestion level, the higher its sorting priority.

[0039] Step S13: Based on the prompt level, control the display status of the interior lights and / or the working status of the DMS.

[0040] Specifically, when the warning level is at the first warning level, the CDC or intelligent driving status coordination controller controls the interior ADS (Autonomous Driving System Marker Lamp) indicator light to turn off, controls the interior ambient lighting to statically display a first color, and controls the DMS to monitor at a first monitoring frequency. The first color is a user-set color or a default color (preferably white), and the first monitoring frequency is the basic monitoring frequency of the DMS (Driver Monitoring System).

[0041] Specifically, when the warning level is the second warning level, the CDC or intelligent driving status coordination controller controls the ADS indicator light in the vehicle to statically display the second color (preferably blue), and controls the ambient light in the vehicle to statically or at the first breathing frequency to display the second color.

[0042] Specifically, when the warning level is the third warning level, the CDC or intelligent driving status coordination controller controls the in-vehicle ADS indicator light and in-vehicle ambient light to display the second color at the first flashing frequency, and controls the DMS to monitor at the second monitoring frequency, the frequency of the second monitoring frequency being higher than the frequency of the first monitoring frequency.

[0043] Specifically, when the warning level is the fourth warning level, the CDC or intelligent driving status coordination controller controls the in-vehicle ADS indicator light to display a third color (preferably yellow) at a first flashing frequency, controls the in-vehicle ambient light to display a third color at a first flashing frequency or a first breathing frequency, and controls the DMS to perform graded warnings. After the CDC or intelligent driving status coordination controller controls the DMS to perform graded warnings, it acquires the driver status signal sent by the DMS. If the driver status signal includes either driver inattention or driver fatigue, it controls the vehicle to execute a preset safety strategy and sends a takeover timeout signal to a preset interface (e.g., a fleet management platform). The preset safety strategy includes at least one of safe slowing, activating hazard warning lights, and maintaining lane centering. The graded warnings first execute a visual icon warning; if takeover is not executed within the first time after executing the visual icon warning, then a visual icon warning and an audio warning are executed; if takeover is not executed within the second time after executing the visual icon warning and an audio warning, then a visual icon warning, an audio warning, and a steering wheel vibration warning are executed. The first and second times are obtained based on set values.

[0044] Specifically, when the alert level is the fifth alert level, the CDC or intelligent driving status coordination controller controls the in-vehicle ADS indicator light and in-vehicle ambient light to display the fourth color (preferably red) at the second flashing frequency, and controls the DMS to execute the highest level alarm. The flashing frequency of the second flashing frequency is higher than the flashing frequency of the first flashing frequency.

[0045] In one implementation, the CDC or intelligent driving status coordination controller sends an emergency event message to the cloud when the alert level is the fifth alert level.

[0046] In one embodiment, the CDC or intelligent driving status coordination controller obtains the intelligent driving lighting status protocol corresponding to the current vehicle location based on the current vehicle location, and sets a second color, a third color, and a fourth color based on the intelligent driving lighting status protocol.

[0047] The ADS indicator light is positioned directly in front of the passenger's field of vision, clearly perceptible to the driver in a normal seating position without requiring significant eye movement. Preferably, the ADS indicator light is installed at the front of the vehicle interior. For the driver, the conspicuous, fixed position of the ADS indicator light becomes an intuitive signal requiring no active interpretation. This eliminates the need for the driver to actively search and analyze icon information from the instrument panel or HUD, significantly reducing cognitive load and improving the driver's responsiveness to takeover requests. For passengers, the ADS indicator light provides clear and unambiguous vehicle behavior instructions. Passengers can understand whether the system is driving or requires manual intervention simply by observing the light color, without needing to ask the driver, fundamentally eliminating confusion and distrust caused by information asymmetry.

[0048] When the CDC or intelligent driving status coordination controller performs the above steps, it acquires status event data and sends the status event data to the server. The status event data includes at least one of the following: vehicle driving status signal, warning level, display status of the in-vehicle ADS indicator light, driver status signal, vehicle location information, and vehicle speed information.

[0049] In one implementation, the server receives status event data sent by one or more CDCs or intelligent driving status coordination controllers, and displays the vehicle location and corresponding alert level in real time on a large screen map based on the status event data, so that fleet managers can intuitively grasp the overall operation status of the fleet.

[0050] In one implementation, when the server receives status event data including the fourth or fifth alert level, it sends an alarm notification to the corresponding account (e.g., the security officer account) so that security management personnel can intervene and handle the situation immediately.

[0051] In one implementation, the server uses status event data to count the frequency, time period, and road segment where each vehicle triggers a takeover request, and uses the status event data to obtain a risk profile of the corresponding driver, providing data support for targeted safety training and management.

[0052] In one implementation, the server uses status event data to calculate the usage rate and duration of the intelligent driving function for the corresponding driver and generates a fleet operation efficiency report. This report can quantitatively assess the actual contribution of the intelligent driving function to operational efficiency and provide a basis for fleet operation decisions.

[0053] This invention provides a method for indicating vehicle driving status. It involves acquiring a vehicle driving status signal, determining a prompt level based on the signal, and controlling the display status of interior lights and / or the operating status of the Driver Assistance System (DMS) based on the prompt level. This invention improves the driver's perception efficiency of changes in intelligent driving status through intuitive status prompts, reducing the risk of the driver missing handover prompts. Simultaneously, it enhances passengers' awareness of the vehicle's intelligent driving status, increasing their perception and trust in intelligent driving behavior.

[0054] Based on the same inventive concept as the foregoing embodiments, this embodiment of the invention provides a vehicle driving status alert system, such as... Figure 3 As shown, the vehicle driving status alert system includes ADCU31, CDC32, DMS33, interior lights34, LIN bus35, and CAN bus36.

[0055] ADCU31 is used to acquire vehicle driving status signals and send them to CDC32 via CAN bus 36.

[0056] The DMS33 includes an infrared camera and a processing unit, integrated behind the steering wheel or mounted on the A-pillar. The infrared camera is aimed at the driver's face so that the DMS33 can monitor the driver's state and obtain the driver's state signal. The driver's state signal is sent to the CDC32 via the CAN bus 36. Based on the DMS control signal sent by the CDC32, the monitoring frequency and / or reminder mode are adjusted.

[0057] CDC32 is used to obtain the warning level based on the vehicle driving status signal, generate DMS control signal and / or lighting control signal based on the warning level, send the DMS control signal to DMS33 through CAN bus 36, and send the lighting control signal to the interior lighting 34 through LIN bus 35.

[0058] CDC32 is also used to acquire status event data and send the status event data to the server via the network. The status event data includes at least one of the following: vehicle driving status signal, warning level, display status of the in-vehicle ADS indicator light, driver status signal, vehicle location information, and vehicle speed information.

[0059] In one implementation, the CDC32 is replaced with an intelligent driving state coordination controller.

[0060] The interior light 34 is used to control the display status of the interior lights based on the light control signal.

[0061] The interior lighting 34 includes the ADS logo light and interior ambient lighting.

[0062] The ADS sign light is a high-brightness, multi-color (blue, yellow, red) LED array. The ADS sign light is located in front of the passenger's field of vision and can be clearly perceived by the driver in a normal sitting position without having to move their eyes significantly.

[0063] The interior ambient lighting consists of RGB LED light strips distributed in the doors, dashboard, footwell, and other areas.

[0064] In one embodiment, the vehicle driving status alert system also includes a server.

[0065] The server receives status event data from one or more CDCs or intelligent driving status collaboration controllers. Based on the status event data, it displays the vehicle location and corresponding alert level on the large screen map in real time, so that fleet managers can intuitively grasp the overall operation status of the fleet.

[0066] The server is used to send an alarm notification to the corresponding account (e.g., the security officer account) when the received status event data includes the fourth or fifth alert level, so that security management personnel can intervene and handle the situation immediately.

[0067] The server is used to statistically analyze the frequency, time period, and road segment where each vehicle triggers a takeover request based on status event data, and to obtain the corresponding driver's risk profile based on the status event data, providing data support for targeted safety training and management.

[0068] The server is used to calculate the usage rate and duration of intelligent driving functions for corresponding drivers based on status event data, and generate fleet operation efficiency reports. It can quantitatively evaluate the actual contribution of intelligent driving functions to operational efficiency and provide a basis for fleet operation decisions.

[0069] The vehicle driving status prompting system of this embodiment is used to implement the vehicle driving status prompting method described above.
