However, the vehicle is likely to be decelerated or stalled due to a fault, and the driver may also slow down the vehicle or even stop the vehicle at the intersection due to the fact that the traffic sign is recognized at the branch intersection. The vehicle is very dangerous when slowing down or stopping at a high-speed road section, and the rear-end collision accident caused by the fact that the vehicle running at a high speed behind cannot slow down or avoid the vehicle can be caused, so that the life safety of people in the vehicle is endangered. However, the prior art is still lack of a technical scheme for safely guiding the decelerating vehicle.
Based on the technical problem, the invention idea of the application is as follows: how to avoid traffic accidents caused by sudden deceleration of vehicles on high-speed road sections.
The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a schematic flow chart of a first embodiment of an alarm method for vehicle driving safety provided by the present application. Referring to fig. 1, the warning method for vehicle driving safety specifically comprises the following steps:
step S101: and when the vehicle is monitored to run on the high-speed road section, acquiring the current speed of the vehicle.
In the present embodiment, it is possible to monitor whether the vehicle is traveling on a highway section by acquiring the road type information. Specifically, a request to acquire road type information may be initiated to a vehicle navigation system. The navigation System searches whether the current position belongs to a highway section on a map according to Global Positioning System (GPS) data of the current position of the vehicle, if so, returns the road type information of '1', and if not, returns '0'. And judging whether the vehicle is in the highway section or not according to the road type information returned by the navigation system.
In this embodiment, when it is monitored that the vehicle is traveling on a highway section, the current vehicle speed may be acquired by a vehicle speed sensor of the vehicle.
Step S102: and when the current vehicle speed is less than a preset first speed threshold, monitoring and acquiring fault information and/or road condition information of the vehicle according to the first speed threshold and a preset second speed threshold.
In this embodiment, when the current vehicle speed is less than the preset first speed threshold, the warning mechanism for the vehicle should be turned on. Illustratively, the first speed threshold may be 80km/h and the second speed threshold may be 40km/h. And monitoring and acquiring the fault information and/or road condition information of the vehicle according to the first speed threshold and the second speed threshold. Exemplarily, when the current vehicle speed is less than 40km/h, monitoring and acquiring fault information of the vehicle; and monitoring and acquiring road condition information of the vehicle when the current vehicle speed is more than 40km/h and less than 80 km/h.
Specifically, the fault information of the vehicle characterizes a fault condition of the vehicle, such as a power system fault, a chassis system fault, a body system fault, and the like. The traffic information represents the current traffic status of the vehicle, such as whether there is an obstacle in front or whether there is a congestion.
Step S103: and carrying out early warning judgment on the vehicle according to the fault information and/or road condition information of the vehicle so as to obtain and play an early warning voice prompt matched with the vehicle to remind a driver on the vehicle.
In this embodiment, the vehicle is pre-warned and determined according to the fault information and/or the road condition information of the vehicle. When the fault information of the vehicle indicates that the vehicle has a power system fault, the fact that the current vehicle speed of the vehicle is smaller than the first speed threshold value is judged to be caused by the power system fault, and the vehicle cannot continue to run normally is judged. And at the moment, acquiring an early warning voice prompt matched with the vehicle, and prompting a driver on the vehicle to drive away from the highway section as soon as possible and drive towards the danger avoiding lane.
For example, when the fault information of the vehicle indicates that the vehicle has no power system fault, and the road condition information indicates that no obstacle or congestion exists in front of the vehicle, it is determined that the current vehicle speed of the vehicle is less than the first speed threshold value, which may be caused by the driver recognizing the traffic sign, so that the vehicle speed is reduced. At the moment, the early warning voice prompt matched with the vehicle is obtained, and a driver on the vehicle is prompted to increase the current vehicle speed to the first speed threshold value as soon as possible.
In the embodiment, when the vehicle is monitored to run on a high-speed road section, the current speed of the vehicle is acquired; when the current vehicle speed is lower than a preset first speed threshold, monitoring and acquiring fault information and/or road condition information of the vehicle according to the first speed threshold and a preset second speed threshold; and carrying out early warning judgment on the vehicle according to the fault information and/or road condition information of the vehicle so as to obtain and play an early warning voice prompt matched with the vehicle to remind a driver on the vehicle. Compared with the prior art, when the vehicle runs on the high-speed road section at a speed lower than the first speed threshold value, the fault information and/or road condition information of the vehicle are monitored and obtained, early warning judgment is carried out according to the fault information and/or road condition information, the current driving condition of the vehicle can be automatically identified, the corresponding early warning voice prompt is obtained and played, early warning is carried out on a driver on the vehicle, safe guidance of the vehicle suddenly decelerated in the high-speed road section is realized, and the problem that traffic accidents are easily caused when the vehicle suddenly decelerates in the high-speed road section in the prior art is solved.
Fig. 2 is a schematic flow diagram of a second embodiment of the warning method for vehicle driving safety provided by the present application, and on the basis of the embodiment shown in fig. 1, referring to fig. 2, a specific implementation manner of the step 102 and the step 103 is as follows:
step S201: and monitoring and acquiring the fault information of the vehicle when the current vehicle speed is judged to be less than the second speed threshold.
Step S202: and acquiring a diagnosis fault code of the vehicle, and judging whether the vehicle has a power system fault according to the diagnosis fault code.
Step S203: and when the vehicle is judged to have the power system fault, generating a first early warning voice prompt for evacuating the high-speed road section to the danger avoiding lane and playing the first early warning voice prompt.
In the embodiment, when the current vehicle speed is less than the second speed threshold, the fault information of the vehicle is monitored and acquired. Illustratively, the second speed threshold may be 40km/h. The fault information of the vehicle characterizes a fault condition of the vehicle, such as a power system fault, a chassis system fault, a body system fault, and the like.
Specifically, a diagnostic trouble code for the vehicle may be obtained. The diagnostic trouble codes may characterize the location and cause of the failure of the vehicle. The diagnostic trouble codes are started by English letters and are followed by 4 digits, such as P1000, B2333, U3210 and the like, and different codes represent different troubles. For example, the diagnostic fault code at the beginning of B indicates that a body system of the vehicle has a fault, the diagnostic fault code at the beginning of C indicates that a chassis system of the vehicle has a fault, the diagnostic fault code at the beginning of P indicates that a power system of the vehicle has a fault, and the diagnostic fault code at the beginning of U indicates that a network or a data communication system of the vehicle has a fault. According to the diagnosis fault code, whether the power system fault exists in the vehicle can be judged.
Specifically, a determination may be made based on the beginning letter of the diagnostic trouble code, and when the diagnostic trouble code begins with P, then the vehicle has a powertrain fault. Powertrain faults include, but are not limited to, a starting system fault that disables or slows the engine, an ignition system fault, a fuel injection system fault, and an air induction system fault. And (3) the vehicle cannot continue to run due to the failure of the power system, and at the moment, a first early warning voice prompt for evacuating the high-speed road section to the danger avoiding lane is generated and played. For example, the first warning voice may be "please drive away from the highway section to the danger avoiding lane as soon as possible, if the vehicle cannot drive normally, please get off the vehicle as soon as possible, place the triangular warning board at one hundred meters of the tail of the vehicle, and go to the safety zone to avoid danger".
In the embodiment, when the power system fault of the vehicle is judged, the vehicle can be triggered to start double flashing.
In this embodiment, when the current vehicle speed is less than the second speed threshold, a diagnostic fault code of the vehicle is obtained, whether the vehicle has a power system fault is judged according to the diagnostic fault code, and when the vehicle is judged to have the power system fault, a first early warning voice prompt for evacuating the high-speed road section to the danger avoiding lane is generated and played, and meanwhile, the vehicle is triggered to start double flashing. When the current speed of the vehicle is too low due to the fact that a power system fault exists in the vehicle, a driver on the vehicle is reminded to evacuate from a high-speed road section as soon as possible, the double-flash prompting rear vehicle is started, rear-end collision accidents caused by the fact that the vehicle running at a high speed behind cannot slow down or avoid the vehicle are effectively avoided, meanwhile, people in the vehicle can avoid danger as soon as possible, and personal safety of the people in the vehicle is guaranteed.
Fig. 3 is a flowchart illustrating a third embodiment of a vehicle driving safety warning method provided in the present application. On the basis of the above-mentioned embodiment shown in fig. 2, referring to fig. 3, after the step S202, the method for alarming vehicle driving safety further includes the following steps:
step S301: and when the fact that the power system fault does not exist in the vehicle is determined, obtaining the road condition information of the vehicle, and determining whether the road condition in front is normal or not according to the running speed of the vehicle in front in the road condition information.
Step S302: and when the road condition in front is determined to be normal, generating a second early warning voice prompt for increasing the current vehicle speed to the first speed threshold value and playing the second early warning voice prompt.
In the present embodiment, when it is determined that the vehicle does not have a power system failure, the road condition information of the vehicle is acquired. The road condition information represents the current road condition of the vehicle, such as whether there is an obstacle in front or whether there is a congestion condition.
Specifically, it may be determined whether the road condition ahead is normal according to the traveling speed of the vehicle ahead in the road condition information. The road condition information is illustratively obtained from an Advanced Driving Assistance System (ADAS). The ADAS system comprises a radar installed in the front of a vehicle, the distance between the vehicle in front and the vehicle is obtained in real time through the radar, and the running speed of the vehicle in front can be determined according to the distance at different moments and the current speed of the vehicle. If the driving speed of the front vehicle is too low, the front vehicle may be blocked, that is, the front road condition is abnormal.
The ADAS system may further include a camera installed in front of the vehicle, and the camera may acquire image information of the vehicle in front of the vehicle, determine whether there is an obstacle in front of the vehicle according to the image information of the vehicle in front of the vehicle, and determine that the road condition in front is abnormal when it is determined that there is an obstacle in front of the vehicle.
In this embodiment, if it is determined that the road condition ahead is normal, the vehicle speed may be reduced due to the driver recognizing the traffic sign at the intersection, and at this time, a second warning voice prompt for increasing the current vehicle speed to the first speed threshold is generated and played. For example, the second warning voice may be "please increase the current vehicle speed to 80km/h as soon as possible".
In this embodiment, when a second warning voice prompt for increasing the current vehicle speed to the first speed threshold is generated and played, the vehicle may be triggered to start the double flashing.
In this embodiment, when it is determined that the vehicle has no power system fault, the road condition information of the vehicle is acquired, whether the road condition ahead is normal or not is determined according to the running speed of the vehicle ahead in the road condition information, and when it is determined that the road condition ahead is normal, a second early warning voice prompt for increasing the current vehicle speed to the first speed threshold is generated and played, and the vehicle is triggered to start double flashing. When the driver reduces the speed of the vehicle due to the recognition of the traffic sign, the driver on the vehicle is reminded to increase the current speed as soon as possible to recover the high-speed driving and start the double-flash prompting rear vehicle, so that the rear-end collision accident caused by the fact that the rear-end high-speed driving vehicle cannot slow down or avoid in time is effectively avoided.
Fig. 4 is a schematic flowchart of a fourth embodiment of the warning method for vehicle driving safety provided by the present application, and on the basis of the embodiment shown in fig. 1, referring to fig. 4, a specific implementation manner of the step 102 and the step 103 is as follows:
step S401: and when the current vehicle speed is greater than the second speed threshold value, acquiring the road condition information of the vehicle.
Step S402: and determining whether the road condition in front is normal or not according to the running speed of the vehicle in front in the road condition information.
Step S403: and when the front road condition is determined to be normal, determining the suggested running speed of the vehicle according to the front vehicle condition information and the rear vehicle condition information of the vehicle in the road condition information.
Step S404: and when the current vehicle speed is lower than the recommended driving vehicle speed, generating a third early warning voice prompt for increasing the current vehicle speed to the recommended driving vehicle speed and playing the third early warning voice prompt.
In this embodiment, when the current vehicle speed is greater than the second speed threshold, the road condition information of the vehicle is obtained. Illustratively, the second speed threshold may be 40km/h. Specifically, whether the road condition ahead is normal or not may be determined according to the driving speed of the vehicle ahead in the road condition information.
For example, the road condition information, particularly the traveling speed of the vehicle ahead of the road condition information, may be obtained from the ADAS system. If the driving speed of the front vehicle is too low, the front vehicle may be blocked, that is, the front road condition is abnormal.
In this embodiment, when it is determined that the road condition ahead is normal, the recommended driving speed of the vehicle is determined based on the vehicle condition information of the vehicle ahead and the vehicle condition information of the vehicle behind in the road condition information. Specifically, the front vehicle condition information includes a front vehicle speed, a distance between the front vehicle and the vehicle, and the rear vehicle condition information includes a rear vehicle speed, a distance between the rear vehicle and the vehicle. The ADAS system comprises radars installed in the front of a vehicle and behind the vehicle, the distance between the front vehicle and the vehicle is acquired in real time through the front radar, the speed of the front vehicle can be determined according to the distance at different moments by combining the current speed of the vehicle, the distance between the rear vehicle and the vehicle is acquired in real time through the rear radar, and the speed of the rear vehicle can be determined according to the distance at different moments by combining the current speed of the vehicle. And determining the recommended running speed of the vehicle according to the speed of the front vehicle, the distance between the front vehicle and the vehicle, the speed of the rear vehicle and the distance between the rear vehicle and the vehicle.
Specifically, the collision model may be obtained from the cloud, and the collision model may be a collision data table. Illustratively, a table of crash data based on the preceding vehicle conditions is shown in table 1.
TABLE 1 Collision data Table based on preceding vehicle conditions
Figure BDA0003799750730000101
Wherein, V F For the front vehicle speed, D F Is the distance between the preceding vehicle and the vehicle, V R1 Is the first recommended travel speed.
With the preceding vehicle condition-based collision data table, the first recommended travel vehicle speed of the vehicle can be determined from the preceding vehicle speed, the distance between the preceding vehicle and the vehicle. Illustratively, when the vehicle speed of the preceding vehicle is 60km/h and the distance between the preceding vehicle and the vehicle is 20m, the first recommended travel vehicle speed of the vehicle is 60km/h.
