[0001] The present invention relates to the field of automotive safety technology, and in particular to a vehicle collision warning method, device, electronic device and storage medium. Background Technology

[0002] Some existing collision warning systems do not allow for adjustment of the warning timing. For the same product, some drivers may perceive frequent warnings as an interference with normal driving and negatively impact their driving experience. Others may feel that the system warns too infrequently, resulting in low product perceptibility.

[0003] Some collision warning functions only adjust after being triggered for the first time. The driver cannot perceive the alarm threshold before the automatic adjustment, and the timing of the alarm before the automatic adjustment may not be suitable for the current driver's habits or the current road conditions, which may lead to a collision accident. Summary of the Invention

[0030] Figure 1 This is a flowchart of a vehicle collision warning method provided in an embodiment of the present invention. This embodiment is applicable to vehicle collision warning situations. The method of this embodiment can be executed by a vehicle collision warning device, which can be implemented in hardware and / or software. The device can be configured in a vehicle collision warning server. The method specifically includes the following steps:

[0031] S110. Determine the target driving information between the current vehicle and the target vehicle.

[0032] The target vehicle includes adjacent vehicles traveling in front of the current vehicle. For example, it can refer to adjacent vehicles traveling on the same road as the current vehicle and whose distance from the current vehicle is within a preset driving distance range. It can also refer to at least one adjacent vehicle traveling on the same road as the current vehicle, as acquired by radar, with the adjacent vehicle closest to the current vehicle being designated as the target vehicle; for example, if there are vehicles A, B, and C traveling on the same road in front of the current vehicle, and the distance between vehicle A and the current vehicle is greater than the distance between vehicle B and the current vehicle, and the distance between vehicle B and the current vehicle is greater than the distance between vehicle C and the current vehicle, then vehicle C is designated as the target vehicle.

[0033] The target driving information includes, but is not limited to, the distance between the current vehicle and the target vehicle, and the relative speed between the current vehicle and the target vehicle.

[0034] As an optional but non-limiting implementation, determining the target driving information between the current vehicle and the target vehicle includes, but is not limited to, steps A1-A2:

[0035] Step A1: Use a radar detector and a forward-looking camera to determine the target driving distance between the current vehicle and the target vehicle.

[0036] Specifically, a radar detector is used to obtain the first driving distance between the current vehicle and the target vehicle; a forward-looking camera is used to obtain the second driving distance between the current vehicle and the target vehicle. The target driving distance is determined based on the difference between the first driving distance and the second driving distance.

[0037] In one optional embodiment of the present invention, if the difference between the first driving distance and the second driving distance is greater than a preset driving distance deviation threshold, then the second driving distance acquired by the forward-looking camera is taken as the target driving distance between the current vehicle and the target vehicle. A difference greater than the preset driving distance deviation threshold indicates that the radar detector is deviating when detecting the target vehicle. While the radar detector is more accurate in detecting distances, it may deviate when detecting targets. Therefore, the second driving distance acquired by the forward-looking camera is taken as the target driving distance between the current vehicle and the target vehicle.

[0038] In another optional embodiment of the present invention, if the difference between the first driving distance and the second driving distance is less than or equal to a preset driving distance deviation threshold, it can be considered that the forward-looking camera has deviated in detecting the driving distance between the current vehicle and the target vehicle. The forward-looking camera is more accurate in detecting the target vehicle, but may deviate in detecting the driving distance between the current vehicle and the target vehicle. Therefore, the first driving distance obtained by the radar detector is taken as the target driving distance between the current vehicle and the target vehicle.

[0039] Step A2: Determine the relative speed between the current vehicle and the target vehicle.

[0040] The relative speed between the current vehicle and the target vehicle is determined using the vehicle navigation speed measurement function built into both vehicles. For example, if the current vehicle's speed is 38 km / h and the target vehicle's speed is 35 km / h, then the relative speed is 3 km / h.

[0041] S120. In response to a collision warning information acquisition request, obtain the driver's driving operation information and the road condition information of the current driving road, and determine the target collision warning method based on the driving operation information and the road condition information.

[0042] In existing technologies, the forward collision warning controller module's self-learning algorithm adjustment unit typically adjusts the following distance warning threshold only after each braking operation by the driver or after the forward collision warning system triggers a warning. Before automatic adjustment, the driver is unaware of the warning threshold, and the timing of the warning before automatic adjustment may not be suitable for the current driver's habits or road conditions, posing a risk of collision. The warning timing is singular and unadjustable, resulting in poor adaptability to drivers with different driving habits and different road conditions. Therefore, this invention provides a vehicle collision warning method that determines the vehicle collision warning mode based on the driver's driving operation information and road condition information.

[0043] In response to a collision warning information request, the forward collision warning system calculates the relative speed to the target vehicle based on the target distance collected by the forward-facing camera and radar detectors, assesses the potential collision risk, and issues an alarm to alert the driver when the alarm conditions are met. The software stored in the forward collision warning system control unit is designed with the following function: it can select one of at least two collision alarm modes to execute via external commands.

[0044] In this embodiment, there are two collision alarm methods, defined as a first sensitivity collision warning method and a second sensitivity collision warning method. The sensitivity value of the first sensitivity collision warning method is lower than that of the second sensitivity collision warning method; for example, the first sensitivity collision warning method includes a warning time of 10 seconds, while the second sensitivity collision warning method includes a warning time of 15 seconds. The alarm parameters in these two sensitivities were set after a series of tests and are permanently embedded in the software, making them unadjustable by the user. Figure 2 As shown, a soft button is designed in the in-vehicle human-machine interface device, corresponding to the first sensitivity collision warning mode and the second sensitivity collision warning mode respectively. The driver can select the appropriate sensitivity collision warning mode based on personal driving operation information and current road condition information.

[0045] See Figure 3 The in-vehicle human-machine interface (HMI) control unit transmits the driver's selected collision warning sensitivity mode information to the vehicle's CAN bus via a CAN signal. The forward collision warning system can switch the sensitivity collision warning mode based on the signals from the HMI and retains the currently selected sensitivity collision warning mode information in the HMI control unit until the driver switches the sensitivity collision warning mode again via a soft button on the HMI. The software in the HMI control unit should also have a mode state memory function; after the HMI is powered on again, the default alarm mode is the previously selected sensitivity collision warning mode. The driver can view the currently selected sensitivity collision warning mode in real time on the HMI.

[0046] In one optional embodiment of the present invention, for vehicles without in-vehicle human-machine interaction devices, a suitable sensitivity collision warning mode can be selected using a fault diagnostic tool. The fault diagnostic tool communicates with the forward collision warning system via CAN through the vehicle's OBD interface. The fault diagnostic tool has a built-in sensitivity collision warning mode selection program, allowing users to select a suitable sensitivity collision warning mode based on their personal driving habits and frequently used road conditions.

[0047] S130. Based on the target driving information, a vehicle collision warning is issued to the current vehicle using a target collision warning method.

[0048] The process involves determining whether the target driving information meets preset driving conditions. For example, it involves determining whether the target driving distance between the current vehicle and the target vehicle is less than a preset driving distance threshold. If it is less than the preset driving distance threshold, a target collision warning method is used to issue a vehicle collision warning to the current vehicle. The preset driving distance threshold corresponds to the target collision warning method. For example, if the first sensitivity collision warning method is determined as the target collision warning method based on driving operation information and road condition information, it means that the driver does not need to issue a warning in advance, and the preset driving distance threshold is less than the preset driving distance threshold of the second sensitivity collision warning method. For example, the preset driving distance threshold for the first sensitivity collision warning method is 3 meters, and the preset driving distance threshold for the second sensitivity collision warning method is 5 meters. If the driver of the current vehicle selects the first sensitivity collision warning method, then when the driving distance between the current vehicle and the target vehicle is less than 3 meters, the first sensitivity collision warning method is used to issue a collision warning to the current vehicle.

[0049] The forward collision warning system control unit sends the alarm information to the vehicle's CAN bus in the form of a CAN signal. A collision warning icon is designed in the instrument cluster; this icon is not displayed when the forward collision warning system control unit does not issue an alarm signal. When the forward collision warning system issues a collision warning signal, the instrument cluster receives the signal from the CAN bus, and the forward collision warning icon flashes rapidly at a fixed frequency, simultaneously emitting an alarm sound at the same frequency to alert the driver to the potential collision hazard. When the instrument cluster outputs the forward collision warning alarm sound, the in-vehicle human-machine interface and other systems need to be muted to ensure the alarm sound is clearly audible.

[0050] This invention provides a vehicle collision warning method. The method involves determining target driving information between the current vehicle and a target vehicle, where the target vehicle includes adjacent vehicles traveling in front of the current vehicle. In response to a collision warning information acquisition request, the method acquires the driver's driving operation information and road condition information of the current road, and determines a target collision warning method based on the driving operation information and road condition information. Based on the target driving information, a vehicle collision warning is issued to the current vehicle using the target collision warning method. The technical solution of this invention includes a collision warning sensitivity adjustment switch in the in-vehicle human-machine interface device, and two collision warning methods are pre-set in the forward collision warning system, with the collision warning methods corresponding to the collision warning sensitivity adjustment switch. The target collision warning method is determined based on the driving operation information and road condition information to meet the driver's perception requirements and avoid affecting the driving experience. Timely warnings are issued in the event of a collision, reducing the incidence of vehicle collisions.

[0051] Figure 4This is a flowchart of another vehicle collision warning method provided in this embodiment of the invention. This embodiment of the invention further optimizes the aforementioned embodiments, and can be combined with various optional solutions from one or more of the above embodiments. For example... Figure 4 As shown, the vehicle collision warning method provided in this embodiment of the invention may include the following steps:

[0052] S410. Determine the target driving information between the current vehicle and the target vehicle.

[0053] S420. Determine candidate collision warning methods for use in warning of vehicle collisions.

[0054] The candidate collision warning methods include, but are not limited to, a first sensitivity collision warning method and a second sensitivity collision warning method, wherein the sensitivity value of the first collision warning method is less than the sensitivity value of the second collision warning method.

[0055] The sensitivity value of a collision warning method can characterize the braking distance and braking time required by the driver during emergency braking. For example, the braking time value of the second collision warning method is greater than that of the first collision warning method. When the driver needs a longer braking time, the second sensitivity collision warning method should be selected.

[0056] S430: Based on driving operation information and road condition information, determine the target collision warning method from the candidate collision warning methods.

[0057] As an optional but non-limiting implementation, determining the target collision warning method from candidate collision warning methods based on driving operation information and road condition information includes, but is not limited to, steps B1-B2:

[0058] Step B1: If the driving operation information is detected to meet the preset driving operation conditions, the second sensitivity collision warning method among the candidate collision warning methods is used as the target collision warning method to be adapted; otherwise, the first sensitivity collision warning method among the candidate collision warning methods is used as the target collision warning method to be adapted.

[0059] The driving operation information includes, but is not limited to, driver braking frequency, braking reaction time, and braking distance. The preset driving operation condition information includes preset braking frequency thresholds, braking reaction time thresholds, and preset braking distance thresholds.

[0060] In one optional embodiment of the present invention, if the driver's braking frequency on the current driving road is greater than a preset braking frequency threshold, and / or the driver's required braking reaction time on the current driving road is greater than a preset braking reaction time threshold, and / or the driver's required braking distance on the current driving road is greater than a preset braking distance threshold, it indicates that the driver's driving situation is relatively cautious, and the second sensitivity collision warning method among the candidate collision warning methods is used as the target collision warning method for adaptation; otherwise, the first sensitivity collision warning method among the candidate collision warning methods is used as the target collision warning method for adaptation.

[0061] In this embodiment of the invention, if the detected driving operation information meets any preset driving operation condition information, the second sensitivity collision warning method can be used as the target collision warning method for adaptation. For example, if the preset braking time threshold is 10 seconds and the driver's required braking time is 12 seconds, then the second sensitivity collision warning method is used as the target collision warning method for adaptation. If the driver's required braking time is 8 seconds, then the first sensitivity collision warning method is used as the target collision warning method for adaptation.

[0062] Step B2: If the road condition information of the current driving road meets the preset warning conditions, then select the second sensitivity collision warning method among the candidate collision warning methods as the target collision warning method to be adapted; otherwise, select the first sensitivity collision warning method among the candidate collision warning methods as the target collision warning method to be adapted.

[0063] The road condition information includes, but is not limited to, whether the current road is congested, the current road surface information, and the current road visibility. The preset warning conditions include, but are not limited to, preset road congestion index thresholds, preset road surface hardening thresholds, and preset visibility thresholds.

[0064] In this embodiment of the invention, if the road condition information of the current driving road meets any preset warning condition, then the second sensitivity collision warning method among the candidate collision warning methods is selected as the target collision warning method; otherwise, the first sensitivity collision warning method among the candidate collision warning methods is selected as the target collision warning method. For example, if the visibility of the current driving road is less than a preset visibility threshold, then the second sensitivity collision warning method is selected as the target collision warning method; otherwise, the first sensitivity collision warning method is selected as the target collision warning method.

[0065] In one optional embodiment of the present invention, when the road condition information meets any preset warning condition information and / or the driving operation information meets any preset driving operation condition information, the second sensitivity collision warning method is used as the target collision warning method to be adapted; otherwise, the first sensitivity collision warning method is used as the target collision warning method to be adapted.

[0066] S440. Based on the target driving information, a vehicle collision warning is issued to the current vehicle using a target collision warning method.

[0067] This invention provides a vehicle collision warning method, which involves: determining target driving information between the current vehicle and a target vehicle; determining candidate collision warning methods for issuing collision warnings; determining a target collision warning method from the candidate methods based on driving operation information and road condition information; and issuing a vehicle collision warning to the current vehicle using the target collision warning method based on the target driving information. By adjusting the target collision warning method according to the driver's driving operation information and road condition information, this invention enhances the driver's perception of collision warnings, avoids affecting the driving experience, and reduces the incidence of vehicle collisions.

[0068] Figure 5 This is a flowchart of another vehicle collision warning method provided in this embodiment of the invention. This embodiment of the invention further optimizes the aforementioned embodiments, and can be combined with various optional solutions from one or more of the above embodiments. For example... Figure 5 As shown, the vehicle collision warning method provided in this embodiment of the invention may include the following steps:

[0069] S510. Determine the target driving information between the current vehicle and the target vehicle.

[0070] S520: In response to a collision warning information acquisition request, acquire the driver's driving operation information and the road condition information of the current road, and determine the target collision warning method based on the driving operation information and the road condition information.

[0071] S530. Determine whether the target driving information meets the preset driving conditions.

[0072] The preset driving condition information includes, but is not limited to, preset driving distance condition information and preset relative speed condition information. The preset driving distance condition information can refer to a preset minimum driving distance between the current vehicle and the target vehicle. For example, if both the current vehicle and the target vehicle are traveling at 100 km / h, and the driving distance between them is less than the preset driving distance condition information, a collision will occur if the target vehicle brakes suddenly. Providing a warning to the current vehicle when the driving distance between them meets the preset driving distance condition information can effectively prevent collisions.

[0073] In one optional embodiment of the present invention, the preset driving distance condition information may also refer to a preset braking distance threshold included in the preset driving operation condition information. For example, when the target driving distance between the current vehicle and the target vehicle is less than the preset braking distance threshold, it indicates that the target driving information meets the preset driving condition information.

[0074] S540. If the preset driving conditions are met, a target collision warning method is used to issue a vehicle collision warning to the current vehicle.

[0075] As an optional but non-limiting implementation, if preset driving condition information is met, a target collision warning method is used to issue a vehicle collision warning to the current vehicle, including but not limited to steps C1-C2:

[0076] Step C1: If the driving distance indicated by the target driving information is detected to meet the preset driving distance conditions, then a vehicle collision warning is issued to the current vehicle using the target collision warning method.

[0077] The preset driving distance condition information includes, but is not limited to, the target driving distance being less than a preset driving distance threshold. If the target driving distance between the current vehicle and the target vehicle is detected to be less than the preset driving distance threshold, it will be determined that the preset driving distance condition information is met. Then, a warning will be issued to the current vehicle based on a determined target collision warning method to avoid a collision.

[0078] Step C2: If the relative speed indicated by the target driving information meets the preset relative speed condition information, and the driving distance indicated by the target driving information meets the preset driving distance condition information, then a target collision warning method is used to issue a vehicle collision warning to the current vehicle.

[0079] The preset relative speed condition information includes, but is not limited to, a relative speed less than a preset relative speed threshold. When the current vehicle and the target vehicle are traveling at a relative speed of 0, if the target vehicle does not brake suddenly, a collision will not occur. If the target vehicle brakes suddenly, and the target distance between the target vehicle and the current vehicle is less than a preset travel distance threshold, a collision will occur between the current vehicle and the target vehicle, which may also affect the normal driving of other vehicles. A warning is issued to the current vehicle to avoid a collision and thus prevent disruption to the normal driving of other vehicles.

[0080] As an optional but non-limiting implementation, the first sensitivity collision warning method includes a first collision warning time and a first audible and visual warning; the second sensitivity collision warning method includes a second collision warning time, a second audible and visual warning, and an image display warning.

[0081] Wherein, the first collision warning time is less than the second collision warning time; the flashing frequency of the first audible and visual warning is less than the flashing frequency of the second audible and visual warning.

[0082] The collision warning time can refer to the time required for the current vehicle and the target vehicle to collide. For example, if the target driving distance between the current vehicle and the target vehicle is greater than a preset driving distance threshold, and the current vehicle and the target vehicle are traveling at the same speed, and the target vehicle brakes suddenly, if the current vehicle does not brake, it is estimated that the current vehicle will collide with the target vehicle after 20 seconds; if the current vehicle brakes, it is estimated that the braking operation will be completed within 10 seconds and a collision will not occur. When using the first sensitivity collision warning method to warn the current vehicle, if there are 14 seconds left before the current vehicle collides with the target vehicle, a first audible and visual warning is used to remind the driver of the current vehicle. When using the second sensitivity collision warning method to warn the current vehicle, if there are 18 seconds left before the current vehicle collides with the target vehicle, a second audible and visual warning and an image display warning are used to remind the driver of the current vehicle.

[0083] In one optional embodiment of the present invention, the flashing frequency of the first audible and visual warning is less than that of the second audible and visual warning. For example, the first audible and visual warning flashes 6 times per minute, and the second audible and visual warning flashes 10 times per minute. By using different flashing frequencies of audible and visual warnings to remind different drivers, the need for collision warnings for drivers can be met, while reducing interference with drivers. For example, based on the driver's driving operation information, if it is determined that the driver is an aggressive type and does not require frequent warnings, to avoid frequent warnings interfering with the driver, a first sensitivity collision warning method can be selected to warn the driver with fewer audible and visual flashes, thus reducing interference with the driver.

[0084] In another optional embodiment of the present invention, the second sensitivity collision warning method further includes an image display warning; the image display warning may refer to displaying a warning icon on the instrument panel of the current vehicle to issue a warning to the driver of the current vehicle in a clearer way, thereby reducing the incidence of collision accidents.

[0085] This invention provides a vehicle collision warning method, which determines target driving information between the current vehicle and a target vehicle; in response to a collision warning information acquisition request, acquires the driver's driving operation information and the road condition information of the current driving road, and determines a target collision warning method based on the driving operation information and road condition information; determines whether the target driving information meets preset driving conditions; if the preset driving conditions are met, then uses the target collision warning method to issue a vehicle collision warning to the current vehicle. By employing the technical solution of this invention, different warning methods are issued to the driver of the current vehicle based on different target driving information, providing a more intuitive warning, reducing the occurrence of collision accidents, and thus avoiding affecting the normal driving of other vehicles.
