Description

Technical Field

[0001] The present invention relates to the traffic field, and specifically relates to a vehicle warning system and a warning method.

Background Art

[0002] Currently, the installation rate and usage rate of advanced driving assistance (ADAS) and automatic driving (ADS) functions in motor vehicles are increasing. In the process of using a vehicle, when the ADAS function is activated or the vehicle is in an automatic driving (ADS) state, people inside the motor vehicle can learn the current status of the ADAS / ADS function and the driving status of the vehicle from prompt sounds and text on the display screen. However, other traffic participants outside the motor vehicle cannot know through a specific route or method that the driving of the motor vehicle is currently controlled by the ADAS / ADS function. Since ADAS / ADS collects environmental data using sensors such as on-board radars and cameras and then makes control decisions, it is difficult to fully guarantee the accuracy and safety of the vehicle's control decisions.

[0003] In addition, as the number of vehicles continues to increase, road safety issues have become increasingly prominent, and rear-end collisions occur frequently. In the prior art, many motor vehicles are equipped with driving assistance functions such as advanced emergency braking system (AEB) and adaptive cruise control (ACC). These functions focus on reducing collision risk from the perspective of the vehicle itself, but do not provide sufficient warnings to other road users. For example, if a vehicle traveling in an adjacent lane suddenly cuts in, a previously safe driving state can turn into an emergency in an instant. On road surfaces with low adhesion coefficients such as rainy or snowy days, the deterioration of road conditions leads to longer braking distances, all of which increase the risk of collision for motor vehicles.

[0004] Therefore, from the perspectives of two-way traffic information and improved safety, it has become urgent to introduce vehicle warning systems into vehicles. This will allow other road users to instantly obtain information on the status of their vehicle's advanced driver-assistance systems (ADAS) / autonomous driving systems (ADS) and the hazard level of the current driving environment, enabling them to instantly predict safety risks and avoid or reduce traffic accidents.

[0005] Furthermore, the information disclosed in the background technology section above is intended to deepen understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0026] Hereinafter, the present invention will be described in detail through specific embodiments to allow those skilled in the art to easily implement the present invention based on the content disclosed herein. The embodiments described below are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative work based on the embodiments described herein shall fall within the protection scope of the present invention. It should be noted that, provided no conflict occurs, the embodiments and the features of the embodiments in the present specification may be combined with each other.

[0027] In the description of the present invention, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "side" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience and simplification of the description of the present invention. It does not explicitly or implicitly indicate that the device or element described must have a specific orientation, or be constructed and operated in a specific orientation, therefore it should not be understood as a limitation on the present invention. It is to be understood that.

[0028] In view of the problems existing in the prior art, the inventor of the present invention installs a vehicle warning system in a motor vehicle, which can warn other road users outside the vehicle according to the risk level of the driving environment, and adjust the flashing frequency of the warning light based on traffic conditions and road surface conditions. This makes it easy for other road users outside the vehicle to immediately predict safety risks, provides more accurate and more immediate warnings to road users, reduces the occurrence of traffic accidents, and helps improve the sense of safety and comfort of road users.

[0029] The vehicle warning system of the present invention includes a driving environment evaluation module 1 and a warning device 2. The driving environment evaluation module 1 can evaluate the driving environment based on the road adhesion coefficient, the relative speed of the motor vehicle (own vehicle) to other traffic participants, the relative distance of the own vehicle to other traffic participants, the mass of the motor vehicle, and the traffic environment conditions. The warning device 2 emits a signal to indicate the degree of danger in the driving environment. The traffic environment conditions described in the present invention include variables that can cause changes in traffic conditions, such as the number of traffic participants, the degree of traffic congestion, and the sudden behavior of other traffic participants (e.g., cutting in due to sudden lane changes, sudden braking). The present invention can improve the two-way nature of traffic information for motor vehicles by immediately and accurately warning of risks in the driving environment to those outside the vehicle, thereby enabling other traffic participants outside the vehicle to immediately anticipate safety risks and avoid or reduce the occurrence of traffic accidents.

[0030] Embodiments of the present invention will be described below with reference to Figures 1 to 5.

[0031] (Example 1) Figure 1 is a schematic diagram of the vehicle warning system 100 according to Embodiment 1 of the present invention.

[0032] As shown in Figure 1, the vehicle warning system of the present invention includes a driving environment evaluation module 1 and a warning device 2. The driving environment evaluation module 1 calculates the probability of collision of a motor vehicle based on collision factors in the motor vehicle's manual driving state, advanced driver assistance state, or automated driving state, and transmits collision probability information based on the motor vehicle's collision probability. The collision factors include, but are not limited to, the road adhesion coefficient, the motor vehicle's relative speed to other traffic participants, the motor vehicle's relative distance to other traffic participants, the mass of the motor vehicle, and traffic environment conditions (e.g., degree of congestion). The warning device 2 receives the collision probability information transmitted from the driving environment evaluation module 1 and, based on the collision probability information, issues a collision warning signal using the flashing of a warning light. The flashing frequency of the warning light increases as the collision probability increases, and the warning light remains constantly lit or is off when the collision probability is zero. As detailed below, when the probability of collision is zero, the warning light can be turned off (turned off) when the motor vehicle is in manual driving mode, and when the motor vehicle is in advanced driver assistance mode or autonomous driving mode, the warning light can be kept on (not flashing), and in this case, a different color (or warning light pattern, e.g., a square or circular pattern) can be used to indicate whether the vehicle is in advanced driver assistance mode or autonomous driving mode.

[0033] The driving environment evaluation module 1 of the present invention evaluates the collision risk (collision probability) of a motor vehicle based on parameters such as road adhesion coefficient, relative speed, relative distance, total mass of the vehicle, and traffic environment conditions, and issues a collision warning signal to the outside of the motor vehicle, indicating the degree of danger in the driving environment. Specifically, the road adhesion coefficient of the present invention is calculated by an algorithm such as an extended Kalman filter (EKF), vehicle speed is measured by a sensor or calculated by an algorithm, and traffic environment conditions can be collected as data by equipment such as cameras and millimeter-wave radar equipment. The driving environment evaluation module 1 calculates the collision probability of the motor vehicle based on the collected information, and the collision probability is set from 0% to 100%, with 0% indicating no collision risk at present, and a higher value indicating a higher collision risk. The collision probability can be calculated using a neural network such as a Bayesian neural network. First, it is necessary to select influencing factors, determine the dependencies between factors, assign weights, and then establish a model. Next, a large amount of actual road traffic measurement data is screened to train the model. By inputting the data of influencing factors into the trained model, the collision probability can be obtained. According to one embodiment of the present invention, the collision probability can be divided into several risk levels (stages), for example, five levels, based on the calculated numerical value. The collision probabilities are divided in the order of extremely high, high, medium, slightly low, and extremely low, from highest to lowest, and the warning device 2 emits different warning signals.

[0034] In this embodiment, the warning device 2 is preferably installed on the vehicle body outside the motor vehicle so that traffic participants outside the vehicle can more easily recognize it. Of course, the installation of the warning device 2 is not limited to the outside of the vehicle, and those skilled in the art may also choose other locations suitable for mounting a warning device that is easily recognizable by traffic participants outside the vehicle. In a preferred embodiment of the above embodiment, the warning device 2 of this embodiment may further preferably include one or more of the following: a forward warning device installed at the front of the motor vehicle, a rear warning device installed at the rear of the motor vehicle, a left-side warning device installed on the left side of the motor vehicle, and a right-side warning device installed on the right side of the motor vehicle.

[0035] As the motor vehicle travels, as shown in Figure 5, the forward warning device warns vehicles approaching from the front, allowing those vehicles to take preventative measures such as steering. The rear warning device warns vehicles approaching from behind, allowing those vehicles to avoid the vehicle by slowing down. The left and right warning devices warn traffic on both sides of the motor vehicle, respectively, allowing traffic on both sides to maintain a safe distance.

[0036] In addition to the embodiments described above, the forward warning device may preferably include one or more warning lights provided at the front of the motor vehicle, the rear warning device may preferably include one or more warning lights provided at the rear of the motor vehicle, the left-side warning device may preferably include one or more warning lights provided on the left side of the motor vehicle, and the right-side warning device may preferably include one or more warning lights provided on the right side of the motor vehicle. Of course, the number and form of the warning devices 2 of the present invention are not limited to the embodiments described above, and the present invention may also employ any other warning devices that can be recognized by traffic participants outside the vehicle, for example, by providing annular warning tape lights surrounding the vehicle body.

[0037] Furthermore, in order to allow traffic participants to look directly ahead without looking down or up too much at the display module, the mounting height of the warning device 2 in this embodiment is preferably greater than 250 mm and less than 1500 mm.

[0038] The environment surrounding a vehicle includes blind spots that are difficult for traffic participants to see directly. To ensure that drivers can easily see the information provided by the warning lights, warning lights should not be installed in these blind spots. In this embodiment, it is preferable to install the warning device 2 above the door step and below the spoiler, but it should not be installed on the windows, windshield, rear window, or any position higher than these.

[0039] Furthermore, to ensure that drivers can clearly see the information from the warning device 2, the mounting position of the warning device 2 should be easily observable. Specifically, this can be achieved by adjusting the warning device 2, for example, by adjusting the angle and color of the warning light, adjusting the angle of the warning light to a position parallel to the line of sight of traffic participants, and improving its visibility with a conspicuous color.

[0040] Finally, when installing the system of the present invention, the installation location of the warning lights should be ensured to comply with local laws and regulations to prevent illegal activities and traffic accidents.

[0041] In a preferred embodiment of the present invention, the warning light can be mounted in several of the following positions.

[0042] (1) Use the vehicle's emblem as a warning light. Provided that the relevant regulations are met, the vehicle's emblem may be designed to function as a warning light. Drivers can naturally notice the status of the warning light when looking straight ahead without having to divert their gaze too much. This approach balances brand identity and safety functionality, improving overall practicality.

[0043] (2) Through-type warning lights. Using through-type warning lights at the rear or front of a vehicle makes them more visible and easier to use as a warning. Such a design improves the visibility of the vehicle and further enhances safety in situations with poor visibility. Such warning lights can effectively warn other road users by selecting appropriate colors and flashing frequencies.

[0044] (3) Fender warning lights. Mounting warning lights on fenders is a unique and practical installation method, and in this embodiment, it is preferable to mount the warning lights along the fender or to design them as warning lights that surround the entire fender. This allows for more conspicuous warning lights to be installed on both sides of the motor vehicle, making it easier to attract the attention of other road users and further improving driving safety.

[0045] (4) A warning light for the door handle. When installing a warning light on the door handle, it can be combined with ambient lighting for the door handle to reduce production costs. In addition, the warning light on the door handle can serve to alert other traffic drivers when they approach the vehicle, improving ease of use.

[0046] Building upon the vehicle warning system of Example 1, the present invention further provides a motor vehicle equipped with the above-described vehicle warning system. As those skilled in the art will understand, the present invention allows for the adaptive installation of the driving condition monitoring module, driving environment evaluation module, and warning device on a motor vehicle depending on the type of vehicle, the vehicle configuration, and the production and assembly platform. This improves the two-way nature of traffic information and helps avoid traffic risks associated with advanced driver assistance systems (ADAS) / autonomous driving (ADS) and hazardous road conditions.

[0047] The vehicle warning method of Embodiment 1 of the present invention will be further described below with reference to Figure 3. Specifically, it includes the following steps S11 to S21.

[0048] In S11, the collision probability of the motor vehicle is calculated based on collision factors in the motor vehicle's manual driving state, advanced driver assistance state, or automated driving state, and collision probability information is generated and transmitted based on the collision probability of the motor vehicle. The collision factors include one or more of the following: road adhesion coefficient, the motor vehicle's relative speed to other traffic participants, the motor vehicle's relative distance to other traffic participants, the motor vehicle's mass, and traffic environment conditions.

[0049] In S21, based on the collision probability information, a collision warning signal is issued by flashing a warning light. The frequency of flashing the warning light increases as the collision probability increases, and when the collision probability is zero, the warning light remains constantly lit or is turned off.

[0050] When in use, the warning device 2 receives collision probability information transmitted from the driving environment evaluation module 1. If the collision probability is greater than 0%, the warning light of the warning device 2 flashes to warn about the external driving environment of the motor vehicle. If the collision probability is zero, the warning light stays on or turns off.

[0051] With the above embodiment, this embodiment can not only immediately and accurately present the advanced driver assistance (ADAS) / autonomous driving (ADS) status of the motor vehicle to those outside the vehicle, but can also warn about the driving environment outside the vehicle. As a result, other road users can immediately anticipate safety risks, thereby avoiding or reducing traffic accidents.

[0052] (Example 2) Figure 2 is a schematic diagram of the vehicle warning system 100' according to Embodiment 2 of the present invention.

[0053] As shown in Figure 2, a vehicle warning system according to another embodiment of the present invention includes a driving environment evaluation module 1', a warning device 2', a driving state monitoring module 3', and a fault handling module 4'. The driving state monitoring module 3' monitors the driving state of the motor vehicle, that is, whether the motor vehicle is in a manual driving state, an advanced driver assistance state, or an automated driving state, and collects manual driving information, advanced driver assistance information, or automated driving information of the motor vehicle. The driving environment evaluation module 1' calculates the probability of collision of the motor vehicle based on collision factors, generates and transmits collision probability information based on the probability of collision of the motor vehicle, and the collision factors include one or more of the following: road adhesion coefficient, relative speed to other traffic participants, relative distance of the motor vehicle to other traffic participants, mass of the motor vehicle, and traffic environment conditions. The warning device 2' receives collision probability information transmitted from the driving environment evaluation module 1', and based on the collision probability information, issues a collision warning signal by flashing a warning light. The frequency of flashing the warning light increases as the collision probability increases, and when the collision probability is zero, the warning light stays lit or turns off.

[0054] Furthermore, the warning device 2' receives driving state information transmitted from the driving state monitoring module 3' and, based on the driving state information, emits a driving state warning signal using the color and / or pattern of the warning light. As an example, the driving state warning signal emitted from the warning light of the present invention may optionally include a first color signal to indicate a manual driving state, a second color signal to indicate an automatic driving state, and a third color signal to indicate an advanced driver assistance state. The first, second, and third color signals preferably include a constantly illuminated state signal to indicate that the probability of collision of the motor vehicle is zero, and a flashing state signal to indicate that the probability of collision of the motor vehicle is greater than zero. Such a design allows for clearer communication of the motor vehicle's driving state and collision probability information, helping other road users better understand and take appropriate action. Specifically, when the motor vehicle is in a manual driving state, the first color signal is constantly illuminated, indicating that the vehicle is controlled by the driver. When a motor vehicle is in autonomous driving mode, the second color signal remains illuminated, indicating that the vehicle is under autonomous driving control. When a motor vehicle is in advanced driver assistance mode, the third color signal remains illuminated, indicating that the vehicle is in advanced driver assistance mode. When the second and third color signals are illuminated, other road users must remain vigilant and make prior judgments and interventions if necessary. When the probability of a collision involving the motor vehicle is greater than zero, the first, second, and third color signals switch to a flashing state to attract the attention of other road users and prompt them to take appropriate evasive action. Optionally, when a motor vehicle is in manual driving mode and the probability of a collision is zero, the warning lights may be turned off (the warning lights will be extinguished). In this configuration, traffic safety can be significantly improved and the occurrence of traffic accidents can be reduced. In short, the warning lights of this embodiment can clearly communicate the vehicle's driving status and collision probability information by emitting signals of different colors and states, helping other road users better understand and take appropriate action, thereby improving traffic safety.Those skilled in the art will understand that, although different colored signals have been used as examples to illustrate different operating state indications, in practice, different patterns or shapes of warning lights may also be used to indicate different operating states, and these too fall within the scope of protection of the present invention.

[0055] The fault handling module 4' continuously collects fault information from the driving condition monitoring module 3', the driving environment evaluation module 1', and the warning device 2'. After collecting the fault information, the fault handling module 4' sends a command to the warning device 2' to turn off the corresponding warning signal. Those skilled in the art will understand that the driving condition monitoring module 3' preferably uses a sensor, program, or software capable of collecting information on advanced driver assistance and / or autonomous driving of the motor vehicle, but that a combination of sensors and programs or software may also be used.

[0056] As shown in Figures 1 and 2, the difference between Embodiment 2 and Embodiment 1 is that the vehicle warning system 100' of Embodiment 2 further includes a fault handling module 4'. The fault handling module 4' of this embodiment monitors the operating status of the driving state monitoring module 3', the driving environment evaluation module 1', and the warning device 2', and immediately resolves the problem of the warning device 2' frequently turning on or off due to a malfunction of the driving state monitoring module 3', the driving environment evaluation module 1', and the warning device 2', thereby avoiding false alarms of warning information and improving the stability and reliability of the vehicle warning system of the present invention.

[0057] In this embodiment, changing the color and flashing frequency of the warning light makes it easier for other traffic participants to distinguish between the driving status of a motor vehicle and warning signals from the external driving environment, thereby reducing the risk of traffic accidents by allowing them to take appropriate action. Furthermore, such changes also help reduce driver eye strain, as prolonged exposure to the same warning light color and flashing frequency can cause eye strain in other traffic participants, potentially affecting their judgment and ability to respond to traffic situations. By changing the color and flashing frequency, the visual senses of other traffic participants can be stimulated, increasing their attention and alertness, and improving driving safety.

[0058] Furthermore, in the case of motor vehicles with a high level of autonomous driving, the driving state monitoring module 3' in the vehicle warning system 100' of the present invention may be set to automatically monitor the manual driving state, advanced driver assistance state, or autonomous driving state of the motor vehicle. Also, in the case of motor vehicles with a low level of autonomous driving, for example, motor vehicles at level L3 or lower, the vehicle warning system of the present invention may be set to allow the driver to directly manually transmit manual driving state information, advanced driver assistance state information, or autonomous driving state information to the driving state monitoring module 3', for example, by pressing a button. Similarly, in the vehicle warning system 100' of this embodiment, when the vehicle is in a manual driving state, the driver can manually turn on the driving environment evaluation module 1' or the driving environment evaluation module 1' can be turned on automatically, and when the driving environment evaluation module 1' determines that there is a risk of collision with the motor vehicle, the warning module 2' emits a corresponding collision warning signal to the outside.

[0059] As one embodiment of the present invention, when the motor vehicle is in manual driving mode, the warning light of the warning module 2' emits a green signal indicating that the vehicle is in manual driving mode; when the motor vehicle is in advanced driver assistance mode, the warning module 2' emits a yellow warning signal indicating that the vehicle is in advanced driver assistance mode; and when the motor vehicle is in autonomous driving mode, the warning module 2' emits a red warning signal indicating that the vehicle is in autonomous driving mode. If the driving environment evaluation module 1' determines, based on various parameters, that there is a risk of collision with the motor vehicle (the probability of collision is greater than 0%), for example, when the road surface becomes wet and slippery and the relative distance of the motor vehicle to other vehicles becomes relatively close, the warning light of the warning module 2' may preferably flash more frequently to further warn about the external driving environment of the motor vehicle. For example, if a motor vehicle is in an advanced driver assistance state and there is a risk of collision (the probability of collision is greater than 0%), the yellow warning light will flash at different frequencies depending on the magnitude of the collision probability or the collision risk level. When the collision probability is small or the collision risk level is low, the danger level of the driving environment is low, and in this case, the frequency of flashing of the yellow warning light is low, prompting traffic participants to pay more attention. As the collision probability increases or the collision risk level improves, the frequency of flashing of the warning light increases, prompting traffic participants to take appropriate collision avoidance measures. When the collision probability is large or the collision risk level is high, the flashing frequency of the collision warning light is in the high range, prompting traffic participants to take emergency collision avoidance measures. The warning light in this embodiment can immediately and accurately warn other traffic participants of the risks of road conditions by flashing frequently. For example, in the event of a multi-vehicle collision on a highway, the frequency of flashing of the warning light can warn about the danger level of the current driving environment, and following vehicles can immediately obtain the degree of danger ahead from the flashing frequency of the road condition warning light and take appropriate preventive measures in advance.

[0060] The vehicle warning method of Embodiment 2 of the present invention will be further described below with reference to Figure 4, and specifically, the method includes the following steps S11' to S31'.

[0061] In S11', the collision probability of the motor vehicle is calculated based on collision factors in the motor vehicle's manual driving state, advanced driver assistance state, or automated driving state, and collision probability information is generated and transmitted based on the collision probability of the motor vehicle, the collision factors include one or more of the following: road adhesion coefficient, the motor vehicle's relative speed to other traffic participants, the motor vehicle's relative distance to other traffic participants, the motor vehicle's mass, and traffic environment conditions.

[0062] In S21', based on the collision probability information, a collision warning signal is issued by flashing a warning light. The frequency of flashing the warning light increases as the collision probability increases, and when the collision probability is zero, the warning light remains constantly lit or is turned off.

[0063] S121' monitors the manual driving state, advanced driver assistance state, and autonomous driving state of the motor vehicle.

[0064] In S122', driving status information is generated and transmitted based on the manual driving state, advanced driver assistance state, and automated driving state.

[0065] In S22', the system receives the operating status information transmitted from the operating status monitoring module and, based on the operating status information, uses the warning lights to issue an operating status warning signal.

[0066] In S31', fault information is continuously collected while generating and transmitting collision probability information and generating and transmitting driving status information. If fault information is collected, the collision warning signal and driving status warning signal are turned off.

[0067] When in use, the warning device 2' receives driving status information transmitted from the driving status monitoring module 3' and collision probability information transmitted from the driving environment evaluation module 1'. On the one hand, when the motor vehicle is in manual, advanced driver assistance, or automated driving state, the warning device 2' turns on or off a warning light of the corresponding color. On the other hand, when the collision probability is greater than 0%, the warning lights of the warning device 2' further warn about the external driving environment of the motor vehicle by flashing a warning light of the corresponding color. The fault collection module 4' collects fault information generated by the driving status monitoring module 3', the driving environment evaluation module 1', and the warning device 2'. After collecting the fault information, it sends a command to the warning device 2' to turn off the corresponding warning signal, and the warning device 2' turns off the collision warning signal and / or driving status warning signal, and repeats step S11'.
