[0002] With the rapid progress of automotive intelligent technologies, lane departure warning and lane change assist have become key auxiliary tools for improving driving safety. Among them, lane departure warning is used to issue a warning signal to the driver when the vehicle unconsciously deviates from the lane, while lane change assist is used to assist the driver in evaluating the traffic conditions behind when changing lanes and reducing the collision risk.

[0003] However, in the prior art, lane departure warning and lane change assist mostly operate independently, lacking effective integration, which limits their comprehensive effect in the actual driving environment. For example, in daily driving, some drivers do not use the turn signal when changing lanes and are not equipped with lane change assist, resulting in the lane departure warning wrongly issuing a sound warning when there is no vehicle, which not only distracts the driver's attention but also may have an adverse impact on the comfort of the passengers in the vehicle.

[0025] The additional aspects and advantages of the present invention will be given in part in the following description, become obvious in part from the following description, or be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The above and / or additional aspects and advantages of the present invention will become obvious and easy to understand from the description of the embodiments in conjunction with the following drawings, wherein:

[0027] Figure 1 is a schematic structural diagram of a vehicle warning device according to an embodiment of the present invention;

[0028] Figure 2 is a schematic flowchart of a vehicle warning method according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0030] The following refers to Figure 1 - Figure 2 Describe a vehicle warning device, method, vehicle and computer-readable storage medium according to an embodiment of the present invention.

[0031] Figure 1 is a schematic structural diagram of a vehicle warning device 100 according to an embodiment of the present invention. As Figure 1 shown, the vehicle warning device 100 includes: an acquisition module 110, a prompt module 120 and a control module 130.

[0032] Among them, the acquisition module 110 is used to acquire the driving information of the vehicle and the road information of the surrounding environment.

[0033] Specifically, the acquisition module 110 is arranged inside the vehicle, including but not limited to various sensors, such as cameras, radars, lidars, ultrasonic sensors, etc., which are used to acquire the driving information of the vehicle and the road information of the surrounding environment. Among them, the driving information of the vehicle includes but not limited to the position, speed, direction of the vehicle, and information such as whether the vehicle deviates from the current lane, etc. The road information of the surrounding environment of the vehicle includes but not limited to information such as whether there are other vehicles in the current lane or adjacent lanes.

[0034] The prompt module 120 is used to output prompt signals of different levels.

[0035] Specifically, the prompt module 120 is also arranged inside the vehicle, which can output prompt signals of different levels to present to the driver or passengers, including but not limited to sound prompts, image prompts, and tactile prompts, etc. For example, a warning light is set on the dashboard to flash, or a warning symbol displayed on the head-up display can be set as a first-level prompt signal, a buzzer is set inside the vehicle to sound, or the vehicle lights flashing can be set as a second-level prompt signal, and the steering wheel and seat generating vibrations can be set as a third-level prompt signal, etc. Further, multiple levels of prompt signals can be enabled simultaneously to enhance the warning effect. It can be understood that by outputting prompt signals of different levels, the driver's attention can be effectively attracted in different scenarios, while reducing unnecessary interference and improving the driver's comfort.

[0036] The control module 130 is connected to the acquisition module 110 and the prompt module 120. The control module 130 is configured to: receive the driving information and road information; determine the current driving state of the vehicle according to the driving information and road information; control the prompt module 120 to output a corresponding level of prompt signal according to the driving state, where different driving states correspond to different levels of prompt signals.

[0037] Specifically, the control module 130 connected to the acquisition module 110 and the prompt module 120 is also arranged inside the vehicle, which can receive the driving information and road information from the acquisition module 110, and analyze the driving information and road information according to the internally preset logic to determine the current driving state of the vehicle, such as the vehicle is driving stably in the current lane, there is no emergency around, or the vehicle begins to unconsciously deviate from the current lane, or there is a vehicle approaching rapidly in the adjacent lane, etc.

[0038] Further, according to the current driving state of the vehicle, the control module 130 can send a control instruction to the prompting module 120 to control the prompting module 120 to output a prompt signal of a corresponding level. Among them, different driving states correspond to different levels of prompt signals, that is, the control module 130 can control different prompting devices in the prompting module 120 to output a prompt signal matching it, so as to provide timely and accurate warnings and assistance to the driver to different extents, thereby helping the driver better master the road conditions, timely respond to potential dangers, and further improve the safety, reliability of driving and the user experience.

[0039] Thus, the above-mentioned vehicle warning device 100 can determine the current driving state of the vehicle according to the obtained driving information and road information during the driving of the vehicle, and then control the prompting module 120 of the vehicle to output a prompt signal of a corresponding level according to the driving state, so as to timely and accurately judge the safety of the current vehicle driving in different scenarios, and accurately output a corresponding warning signal, providing timely and accurate warnings and assistance to the driver, thereby helping the driver drive the vehicle easily and confidently while solving the problems of frequent warnings and false warnings causing traffic accidents during the driving of the vehicle, and further improving the safety, reliability of driving and the user experience.

[0040] In an embodiment of the present invention, when determining the current driving state of the vehicle according to the driving information and road information, the control module 130 is configured to: when it is determined that the vehicle deviates from the current lane and there is no vehicle in the adjacent lane in the deviation direction within a preset distance range in the driving direction of the vehicle, determine that the vehicle is in the first driving state.

[0041] Specifically, in the process of determining the current driving state of the vehicle according to the driving information and road information, when it is determined that the vehicle deviates from the current lane, that is, the driving trajectory of the current vehicle exceeds the range of the normal lane line, if there is no other vehicle in the adjacent lane in the deviation direction within a preset distance range in the driving direction of the vehicle, the vehicle state can be determined as the first driving state.

[0042] In a specific embodiment, the preset distance range is a safety distance range, that is, the distance range within which the current vehicle will not collide with other vehicles during driving. Specifically, the preset distance range can be dozens or hundreds of meters in front of and behind the vehicle centered on the vehicle, and can be set according to specific circumstances. For example, the distances in front of and behind the vehicle during driving can be set to be the same, such as 50 meters at the same time, or the distances in front of and behind the vehicle during driving can be set to be different, such as 50 meters in front of the vehicle during driving and 100 meters behind the vehicle during driving, or 50 meters behind the vehicle during driving and 100 meters in front of the vehicle during driving.

[0043] In an embodiment of the present invention, when controlling the prompting module 120 to output a prompting signal of a corresponding level according to the driving state, the control module 130 is configured to: when the vehicle is in a first driving state, control the prompting module 120 to output a first-level prompting signal for prompting that the vehicle has deviated from the lane.

[0044] Specifically, when controlling the prompting module 120 to output a prompting signal of a corresponding level according to the driving state, if the vehicle is in a first driving state, that is, the vehicle has deviated from the current lane, but no other vehicles are detected in the adjacent lane in the preset distance range in the deviation direction, it indicates that although the vehicle has deviated from the current lane, there is no vehicle in the adjacent lane, so it does not pose a serious safety risk. At this time, the control module 130 can control the prompting module 120 to output a first-level prompting signal to remind the driver that the vehicle has deviated from the current lane.

[0045] In an embodiment of the present invention, the prompting module 120 includes: a first prompting device disposed inside the vehicle, and the first prompting device is used to output a first-level prompting signal.

[0046] Specifically, the prompting module 120 includes a first prompting device disposed inside the vehicle. When the control module 130 determines that the vehicle is in a first driving state according to the driving information and road information, it can send a control command to the first prompting device to make the first prompting device output a corresponding first-level prompting signal. It can be understood that the first-level prompting signal has mildness, that is, the intensity of the first-level prompting signal is weak, which can represent a situation with a small degree of danger, so as to ensure that while not affecting driving comfort, the driver is aware that they need to pay attention to the driving state of the current vehicle, thereby improving driving safety.

[0047] In an embodiment of the present invention, the first prompting device includes: a dashboard.

[0048] Specifically, the dashboard can be used as the first prompting device to output a first-level prompting signal, including but not limited to flashing a specific area or indicator light on the dashboard at a specific frequency and mode, or displaying a short text prompt or a specific warning icon for prompting. For example, when the vehicle unconsciously deviates from the lane line, but no other vehicles are detected in the adjacent lane in the preset distance range in the deviation direction, the dashboard can turn on the yellow lane departure warning light, and the color of the lane line mark on the dashboard can also turn yellow at the same time, so as to gently remind the driver to pay attention to the lane position.

[0049] In one embodiment of the present invention, when determining the current driving state of the vehicle according to the driving information and road information, the control module 130 is configured to: when it is determined that the vehicle does not deviate from the current lane and there is a vehicle in the preset distance range in the driving direction of the vehicle in the adjacent lane, determine that the vehicle is in the second driving state.

[0050] Specifically, in the process of determining the current driving state of the vehicle according to the driving information and road information, when it is determined that the vehicle does not deviate from the current lane, that is, the driving trajectory of the current vehicle is within the range of the normal lane line, if there is another vehicle in the preset distance range in the driving direction of the vehicle in the adjacent lane, it can be determined that the vehicle state is the second driving state.

[0051] In a specific embodiment, the preset distance range is a safety distance range, that is, the distance range in which the current vehicle will not collide with other vehicles during driving. Specifically, the preset distance range can be dozens or hundreds of meters in front of and behind the vehicle centered on the vehicle, and can be set according to specific situations. For example, the distances in front of and behind the vehicle during driving can be set to the same distance, such as 50 meters at the same time, or the distances in front of and behind the vehicle during driving can be set to different distances, such as 50 meters in front of the vehicle during driving and 100 meters behind the vehicle during driving, or 50 meters behind the vehicle during driving and 100 meters in front of the vehicle during driving.

[0052] In one embodiment of the present invention, when controlling the prompting module 120 to output a prompting signal of a corresponding level according to the driving state, the control module 130 is configured to: when the vehicle is in the second driving state, control the prompting module 120 to output a second-level prompting signal for prompting that there is a vehicle approaching in the adjacent lane of the vehicle.

[0053] Specifically, when controlling the prompting module 120 to output a prompting signal of a corresponding level according to the driving state, if the vehicle is in the second driving state, that is, the current vehicle's own driving state is normal, but other vehicles are detected in the preset distance range in the adjacent lane, it means that although the vehicle does not deviate from the current lane, there is a risk of collision during driving due to the presence of vehicles in the adjacent lane. At this time, the control module 130 can control the prompting module 120 to output a second-level prompting signal to remind the driver to pay attention to the driving states of the current vehicle and the vehicles in the adjacent lane and take corresponding measures to avoid collisions.

[0054] In one embodiment of the present invention, the prompting module 120 includes: a second prompting device arranged in the vehicle, and the second prompting device is used to output a second-level prompting signal.

[0055] Specifically, the prompt module 120 includes a second prompt device disposed inside the vehicle. When the control module 130 determines that the vehicle is in the second driving state based on the driving information and road information, it can send a control instruction to the second prompt device to cause the second prompt device to output a corresponding second-level prompt signal. It can be understood that the second-level prompt signal is more obvious than the first-level prompt signal, meaning that the driver needs to maintain a certain level of alertness to cope with situations such as lane changes and overtaking that may occur during driving at any time.

[0056] In an embodiment of the present invention, the second prompt device includes a light display member disposed on the rearview mirror of the vehicle.

[0057] Specifically, the light display member on the rearview mirror of the vehicle can serve as the second prompt device and output a second-level prompt signal, including but not limited to flashing at a specific frequency and pattern. For example, when the vehicle has not deviated from the current lane but there is a vehicle approaching in the adjacent lane, the light display member on the side where the vehicle is approaching can light up and flash, and select the corresponding frequency and pattern according to the distance between the vehicle in the adjacent lane and the current vehicle. For example, when the distance between the vehicle in the adjacent lane and the current vehicle is 100 meters, the light display member flashes with a yellow light every five seconds, and when the distance between the vehicle in the adjacent lane and the current vehicle is 50 meters, the light display member flashes with a red light every three seconds, providing timely prompts for the driver so that the driver can understand the vehicle situation in the adjacent lane based on the state of the light display member, thereby avoiding collisions.

[0058] In an embodiment of the present invention, when determining the driving state of the vehicle based on the driving information and road information, the control module 130 is configured to: when it is determined that the vehicle has deviated from the current lane and there is a vehicle in the adjacent lane in the preset distance range in the driving direction of the vehicle, determine that the vehicle is in the third driving state.

[0059] Specifically, during the process of determining the driving state of the vehicle based on the driving information and road information, when it is determined that the vehicle has deviated from the current lane, that is, the driving trajectory of the current vehicle exceeds the normal range of the lane line, if there are other vehicles in the adjacent lane within the preset distance range in the driving direction of the vehicle, the vehicle state can be determined as the third driving state.

[0060] In a specific embodiment, the preset distance range is a safety distance range, that is, the distance range within which the current vehicle will not collide with other vehicles during driving. Specifically, the preset distance range can be dozens or hundreds of meters in front of and behind the vehicle centered on the vehicle, which can be set according to specific circumstances. For example, the distances in front of and behind the vehicle during driving can be set to be the same, such as 50 meters at the same time, or the distances in front of and behind the vehicle during driving can be set to be different. For example, the distance in front of the vehicle during driving can be set to 50 meters, and the distance behind the vehicle during driving can be set to 100 meters, or the distance behind the vehicle during driving can be set to 50 meters, and the distance in front of the vehicle during driving can be set to 100 meters.

[0061] In an embodiment of the present invention, when controlling the prompt module 120 to output prompt signals of corresponding levels according to the driving state, the control module 130 is configured to: when the vehicle is in the third driving state, control the prompt module 120 to output the first-level prompt signal, the second-level prompt signal, and the third-level prompt signal for indicating that the vehicle is in danger of collision.

[0062] Specifically, when controlling the prompt module 120 to output prompt signals of corresponding levels according to the driving state, if the vehicle is in the second driving state, that is, the vehicle has deviated from the current lane, and other vehicles are detected within the preset distance range in the adjacent lane, it indicates that the current vehicle fails to maintain driving within the lane, has crossed the lane line, and there are vehicles in the adjacent lane, and there is a risk of collision during driving. At this time, the control module 130 can control the prompt module 120 to output the first-level prompt signal, the second-level prompt signal, and the third-level prompt signal for indicating that the vehicle is in danger of collision, that is, by outputting multiple prompt signals, reminding the driver to pay attention to the driving states of the current vehicle and the vehicles in the adjacent lane, and taking corresponding measures to avoid collisions.

[0063] In an embodiment of the present invention, the prompt module 120 includes: a third prompt device disposed inside the vehicle, and the third prompt device is used to output a third-level prompt signal.

[0064] Specifically, the prompt module 120 includes a third prompt device disposed inside the vehicle. When the control module 130 determines that the vehicle is in the third driving state according to the driving information and road information, it can send a control instruction to the third prompt device to make the third prompt device output the corresponding third-level prompt signal. It can be understood that the third-level prompt signal is stronger than the first-level prompt signal and the second-level prompt signal, that is, the intensity of the third-level prompt signal is stronger, which can represent a situation with a greater degree of danger, so as to ensure that the driver realizes the danger in the shortest time and thus improve driving safety.

[0065] In an embodiment of the present invention, the third prompting device includes a vibration device disposed at a target position that can be perceived by the driver.

[0066] Specifically, the vibration device at the target position that can be perceived by the driver can serve as the third prompting device and output a third-level prompting signal, including but not limited to vibrating at a specific frequency. For example, when the vehicle deviates from the current lane and there is a vehicle approaching in the adjacent lane, the vibration device at the target position on the side where the approaching vehicle is located can vibrate, and select the corresponding frequency and intensity according to the distance between the vehicle in the adjacent lane and the current vehicle. For example, when the distance between the vehicle in the adjacent lane and the current vehicle is 100 meters, the vibration device vibrates every 3 seconds, vibrates for 1 second each time, and vibrates 3 times. When the distance between the vehicle in the adjacent lane and the current vehicle is 50 meters, the vibration device vibrates every 1 second, vibrates for 3 seconds each time, and vibrates 3 times, and the vibration intensity increases, so that the driver can understand the situation of the vehicle in the adjacent lane according to the state of the vibration device, thereby avoiding collisions.

[0067] In an embodiment of the present invention, the vibration device includes at least one vibration motor.

[0068] Specifically, the vibration device includes at least one vibration motor, which is used to generate a vibration effect when the vehicle is in a high-risk driving state and provide a tactile warning to the driver. It can be understood that since the vibration motor has the characteristics of small occupied space, light weight, convenient installation, and can generate an efficient vibration output ability, etc., therefore, by installing at least one vibration motor at a position that can be clearly perceived by the driver, it can ensure that the vibration effect can be directly and effectively transmitted to the driver, attract the driver's attention, prompt the driver to take corresponding measures, and effectively avoid accident risks.

[0069] In an embodiment of the present invention, the target position includes the backrest and / or seat cushion of the driver's seat.

[0070] Specifically, the target position includes the backrest and / or seat cushion of the driver's seat, that is, the vibration device can be installed separately on the backrest or seat cushion of the vehicle's driver's seat, or installed on the backrest and seat cushion of the vehicle's driver's seat at the same time. Among them, the backrest of the driver's seat is the part where the driver's back leans during driving. Installing the vibration device on the backrest can ensure that when the vibration device is started, the generated vibration can be quickly transmitted to the driver's back through the backrest. Secondly, the seat cushion is the part that contacts the driver's buttocks and thighs. Installing the vibration device on the seat cushion can also ensure that the vibration can be transmitted to the driver's body.

[0071] Further, the vibration device can be installed at the center position or on both sides of the driver's seat backrest or seat cushion. Taking the installation on both sides of the driver's seat backrest as an example, when the vehicle deviates from the current lane and there is a vehicle approaching in the adjacent lane in the deviation direction, the vibration device on the side where the vehicle is approaching can start vibrating to provide timely prompts for the driver, so that the driver can understand the vehicle situation in the adjacent lane according to the position and state of the vibration device, thereby avoiding collisions.

[0072] In summary, for the vehicle warning device 100 according to the embodiment of the present invention, during the driving process of the vehicle, the driving state of the vehicle can be determined according to the acquired driving information and road information, and then the prompt module 120 of the vehicle can be controlled according to the driving state to output prompt signals of corresponding levels, so as to timely and accurately judge the safety of the current vehicle driving in different scenarios and accurately output corresponding warning signals, providing timely and accurate warnings and assistance for the driver. Thus, while helping the driver drive the vehicle easily and confidently, the problems of frequent early warnings and traffic accidents caused by false early warnings during the vehicle driving process are solved, and further, the driving safety, reliability and user experience are improved.
