All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Referring to fig. 1, a flow chart of steps of an emergency linkage method is shown, and the method is applied to a current vehicle, and specifically may include the following steps:
and step S1, when the vehicle condition information of the vehicle is detected to be a driving fault or an accident event exists in the traffic environment, sending corresponding alarm information to at least one networked vehicle within a first preset distance.
In this step, when it is detected that the vehicle condition information of the vehicle is any one of the following information, it is determined that the vehicle condition information is a driving fault: vehicle light information, lane change information, tire pressure failure information, vehicle failure information, collision information, emergency braking information, vehicle speed information, vehicle acceleration information, and the like. The vehicle condition information reflects the condition of the vehicle during traveling.
Determining that an accident event exists when detecting that any one of the following environmental conditions exists in the traffic environment: warning sign information, road maintenance information, etc. The traffic environment refers to a road environment in which the vehicle is located during traveling, for example, when the vehicle travels on a road, obstacles such as pedestrians near the road, warning signs and warning signs provided on the road.
The vehicle light information comprises vehicle light information such as a brake light, a steering light, an alarm light and the like; the lane change information includes a transition of the vehicle from the current lane to another lane; the tire pressure failure information refers to tire pressure failure information sent when the tire pressure of the vehicle is lower than the safe tire pressure or the vehicle blows out; the vehicle fault information comprises vehicle fault information which influences normal driving of the vehicle, such as pedal damage, throttle damage, sensor damage and the like; the collision information refers to collision information sent by a collision between the vehicle and an obstacle; the emergency braking information refers to emergency braking information sent when a driver suddenly steps on a brake pedal to perform emergency braking; the vehicle speed information refers to the current vehicle speed information of the vehicle; the vehicle acceleration information refers to vehicle acceleration information that is issued when the vehicle acceleration exceeds a safety limit.
The warning board information may be triangle warning board information, and the road maintenance information may be road maintenance marks placed on the highway.
In addition, referring to fig. 2, the vehicle light information may be monitored by the vehicle body controller, and the vehicle failure information and the emergency braking information may also be monitored by the vehicle body controller.
The lane change information, the warning board information and the road maintenance information can be monitored through the intelligent forward-looking camera, and the intelligent forward-looking camera can not only identify a lane line where the vehicle is located currently, but also identify traffic signal marks around the current vehicle.
The tire pressure failure information can be detected in real time by the tire pressure controller.
The collision information and the vehicle acceleration information can be monitored through the air bag electronic control unit, the air bag electronic control unit measures the current collision information of the vehicle through the collision sensor, the current acceleration information of the vehicle is measured through the acceleration sensor, when the vehicle acceleration exceeds the safety limit, the acceleration sensor can send out the vehicle acceleration information, and when the vehicle collides, the acceleration sensor can send out the collision information.
The speed information can be monitored in real time through a wheel speed sensor, the speed information can be calculated according to the relative speed between the current vehicle and the surrounding vehicle through an ACC radar, the speed information is compensated with the ACC radar through the wheel speed sensor, when the ACC radar breaks down, the speed of the current vehicle can be measured through the wheel speed sensor, and the current speed of the vehicle can be monitored more accurately under the combined action of the speed information and the ACC radar.
Furthermore, referring to fig. 2, an emergency linkage controller is arranged on the vehicle, and the emergency linkage controller is respectively connected with the vehicle body controller, the wheel speed sensor, the tire pressure sensor, the airbag electric control unit, the intelligent forward-looking camera and the ACC radar. The vehicle body controller sends the detected vehicle light information, vehicle fault information and emergency braking information to the emergency linkage controller; the intelligent forward-looking camera sends the detected lane change information, the warning board information and the road maintenance information to the emergency linkage controller; the tire pressure controller sends the detected tire pressure failure information to the emergency linkage controller; the airbag electronic control unit sends the detected collision information and the vehicle acceleration information to an emergency linkage controller; and the wheel speed sensor and the ACC radar send the detected vehicle speed information to the emergency linkage controller.
After receiving any one of the above-mentioned information, the emergency linkage controller sends the information to other networked vehicles within a first preset distance, and therefore before sending the information to other networked vehicles, a real-time communication channel between the current vehicle and the networked vehicles needs to be established, so that mutual interaction between the vehicles can be performed, and based on this, referring to fig. 2, the communication process of the real-time communication channel is as follows:
and step A, establishing a real-time communication channel with the networked vehicle through a vehicle-mounted wireless terminal.
In this step, after receiving any one of the above information, the emergency linkage controller in the current vehicle can communicate with the 5G network through the vehicle-mounted wireless terminal, and automatically call or receive a call to a networked vehicle within a first preset distance from the current vehicle, thereby establishing a real-time communication channel.
And a substep B of sending the alarm information to the networked vehicles within a first preset distance when the distance between the current vehicle and the networked vehicles is less than or equal to the first preset distance.
In this step, the first preset distance may be 200 meters, may also be 150 meters or 250 meters, and the like, and within the first preset distance of the current vehicle, the current vehicle may establish a real-time communication channel with the networked vehicle, and send the warning information sent by the current vehicle to the networked vehicle. And based on each networked vehicle on the road, the vehicle can be taken as a central point, and within a first preset distance, when the vehicle breaks down or the surrounding environment is found to break down, the warning information is sent to the networked vehicles within the first preset distance, so that a mutually communicated network is formed among the vehicles on the whole road, once a problem occurs at any place on the road, the warning information can be mutually transmitted between the vehicles to traverse the rest places on the road, and the secondary occurrence of traffic accidents is reduced at the source.
And C, closing the real-time communication channel when the distance between the current vehicle and the networked vehicle is greater than the first preset distance.
In this step, since the current vehicle may send the warning information to the networked vehicles outside the first preset distance through the networked vehicles inside the first preset distance, it may not be necessary to establish a real-time communication channel between the current vehicle and the networked vehicles outside the first preset distance.
The current vehicle sends alarm information to other networked vehicles within the first preset distance, so that the other networked vehicles know whether other vehicles except the current vehicle have faults or whether traffic faults exist in the surrounding environment of the other vehicles, and therefore speed reduction, emergency braking or evasive measures can be taken in advance to solve the problem of secondary traffic accidents caused by the visual field.
And step S2, after the at least one networked vehicle receives the warning information, generating a prompt signal based on the warning information so as to warn the driver.
In the step, each vehicle is provided with a head-up display system or a central control screen and other display systems, the display systems are connected with an emergency linkage controller, and after the emergency linkage controller on the current vehicle sends alarm information to the networked vehicles, the networked vehicles can display the alarm information through the head-up display system or the central control screen and other displays.
The prompt signal may be a voice prompt, a light prompt, a front vehicle steering prompt, a front vehicle braking prompt, a vehicle automatic deceleration prompt, a vehicle automatic lane change prompt, a front vehicle emergency braking prompt, or the like. After receiving the prompt signals on the display system, the driver can take speed reduction, emergency braking, steering or evasion measures and the like in advance to solve the problem of secondary traffic accidents caused by the visual field.
For example, referring to fig. 3, when a vehicle a collides, and an airbag electronic control unit of the vehicle a detects that the vehicle a collides through a collision sensor, collision information is output and sent to an emergency linkage controller, the emergency linkage controller automatically sends out warning information to all networked vehicles B, C, D within 200 meters backward through a real-time communication channel, and even if the field of view of the vehicle B, C, D within 200 meters backward is limited, a deceleration or emergency braking measure can be taken in advance according to an emergency warning signal of the vehicle ahead, so that a secondary traffic accident is avoided.
For another example, referring to fig. 4, when the car a wants to overtake and change lane, the car a transmits the turn signal information to the car in the rear overtaking direction lane, and the head-up display of the B, C, D car in the rear overtaking direction lane indicates that the car a changes lane to the direction of the car lane, so that even if the field of view of the rear car C, D is limited, the measure of reducing the speed or keeping the distance between the cars can be taken in advance according to the indication signal; when the A vehicle does not turn to the turn light and suddenly changes lanes, the A vehicle recognizes lane change information of the A vehicle according to the intelligent front-view camera, the A vehicle can also send the lane change information of the A vehicle to the rear through the real-time communication channel, the A vehicle is prompted to change lanes to the direction of the A vehicle on a head-up display system of B, C, D vehicles in the lane of the rear overtaking direction, and even if the vision of the rear vehicle is limited, measures for reducing the speed or keeping the distance between the vehicles can be taken in advance according to the prompt signals, so that secondary traffic accidents are avoided.
In a possible implementation manner, steps S1 to S2 may be applied to sending warning information to surrounding networked vehicles for prompting in case of vehicle abnormality; if the traffic information under normal conditions needs to be displayed on the display system, referring to fig. 2, the method can be implemented by the following steps:
and step S3, transmitting the detected driving state information to a remote support center in real time every preset time interval of the current vehicle.
In this step, the driving state information may be transmitted to a remote traffic support center in real time through the vehicle-mounted wireless terminal. The driving state information includes information such as the own vehicle identification code, the vehicle geographic coordinates, the driving lane, the driving speed and the like.
The specific process of sending the running state information of the current vehicle to a remote traffic support center in real time is as follows: firstly, a vehicle Beidou positioning system measures the geographic coordinates and the running speed of a vehicle and transmits the geographic coordinates and the running speed to an emergency linkage controller; the intelligent forward-looking camera recognizes a lane line where the current vehicle is located and a traffic signal mark and transmits the lane line and the traffic signal mark to the emergency linkage controller, then the emergency linkage controller matches a road infrastructure map and geographic coordinates of the vehicle to determine a driving lane where the current vehicle is located, and finally the emergency linkage controller can send out a vehicle identification code of the current vehicle. Therefore, the collection of the vehicle geographic coordinates, the running speed, the running lane, the vehicle identification code and other running state information of the vehicle is realized on the emergency linkage controller; and after receiving the plurality of running state information, the emergency linkage controller sends the plurality of running state information to the remote support center through the vehicle-mounted wireless terminal.
Step S4: and the remote support center generates a second traffic road condition map based on the driving state information of the current vehicle, the driving state information sent by all vehicles within a second preset distance from the current vehicle and the environment information of all vehicles.
In this step, the remote support center generates a first traffic road condition map based on the driving state information of the current vehicle and the driving state information sent by all vehicles within a second preset distance from the current vehicle; and generating the second traffic road condition map according to the first traffic road condition map and the environmental information of all vehicles on the road. The second preset distance may be a distance occupied by the whole highway.
For example, the emergency linkage controller is connected with a 5G mobile network through a vehicle-mounted wireless terminal, and sends driving state information such as a vehicle identification code, vehicle geographic coordinates, a driving lane, a driving speed and the like to a remote traffic support center, and the information can be updated once every 50 ms; the remote traffic support center collects the vehicle identification codes, the vehicle geographic coordinates, the driving lanes, the driving speed signals and other driving state information of all vehicles on the highway, and generates a first traffic road condition map by combining a highway infrastructure map. The first traffic map is a highway traffic map related to the vehicle.
The remote support center generates a second traffic road condition map according to the first traffic road condition map and collects the environmental information of all vehicles on the road such as weather forecast, images of a camera of the highway, images of an automobile data recorder of the networked vehicles and the like. The second traffic road condition map is a real-time highway traffic road condition map, and the real-time highway traffic road condition map comprises vehicles and surrounding environment.
And step S5, acquiring the second traffic road condition map to display the second traffic road condition map.
For example, the Beidou positioning system sends the measured vehicle geographic coordinates to the emergency linkage controller, the emergency linkage controller sends the vehicle geographic coordinates to the navigation system, the navigation system loads a second traffic road condition map within 1 km from the front and back of the current vehicle geographic coordinates according to the vehicle geographic coordinates measured by the Beidou positioning system and sends the second traffic road condition map to the emergency linkage controller, and the emergency linkage controller forwards the second traffic road condition map to the display system to display the second traffic road condition map within 1 km from the front and back.
The second traffic road condition map is provided for the navigation system through the far-end support center to be displayed on the display system, and a driver can know the driving condition of the vehicle on the road through the second traffic road condition map conveniently before a traffic accident does not occur.
In steps S1 to S5, when the vehicle Beidou positioning system detects that the vehicle geographic coordinates enter the geographic coordinates near the entrance of the expressway, and the distance between the two coordinates is less than 100 meters, the vehicle navigation system is automatically started.
When the vehicle Beidou positioning system detects that the geographic coordinates of the vehicle coincide with the geographic coordinates of the entrance of the expressway, the vehicle navigation system loads a second traffic road condition map within 1 km in front and back of the vehicle, which is provided by a far-end traffic support center, according to the geographic coordinates of the vehicle detected by the Beidou positioning system, updates every 1s along with the change of the geographic coordinates of the vehicle, and simultaneously activates an emergency linkage controller and an intelligent forward-looking camera to determine the vehicle identification code and the driving lane of the vehicle in real time.
When a vehicle drives into the highway, the vehicle-mounted navigation system sends vehicle identification codes of the same road within 200 meters before and after the vehicle to the emergency linkage controller in real time, and the vehicle identification codes are updated once every 50 ms; and the emergency linkage controller loads a second traffic road condition map within 200 meters before and after the vehicle provided by the vehicle navigation system, and updates the second traffic road condition map once every 50ms, so that the updated second traffic road condition map can be obtained in time.
The emergency linkage controller is communicated with a 5G mobile network through a vehicle-mounted wireless terminal, automatically calls or receives calls of networked vehicles within a range of 200 meters away from the vehicle, establishes a real-time communication channel, and closes the real-time communication channel when the distance between the vehicles exceeds 200 meters.
In the process, when the vehicle runs on the expressway, the surrounding road conditions can be checked in real time through the second traffic road condition map under normal conditions; under the abnormal condition, the information of the vehicle can be sent to other networked vehicles through the real-time communication channel, and the information sent by other vehicles can be received in real time through the real-time communication channel, so that the problem of secondary traffic accidents caused by the visual field can be avoided.
And under the abnormal condition, the warning information can be mutually transmitted through the real-time communication channel, the safety threat degree of the front vehicle and the road condition to the vehicle can be judged by combining the second traffic road condition, and different warning information is sent to other networked vehicles according to the difference of the safety grades.
