When a proprietary vehicle performs an emergency task such as a police, fire, ambulance, emergency, etc., it is often necessary to instruct other vehicles on the roadway to avoid. At present, special vehicles usually remind surrounding vehicles through audible and visual alarms. However, the sound insulation effect of the current vehicle is stronger and stronger, drivers of surrounding vehicles are difficult to timely receive acousto-optic alarm information, and the early warning effect of the scheme is poor. Meanwhile, vehicles receiving the acousto-optic alarm information often cannot determine how to effectively cooperate with special vehicles.

At present, for solving audible-visual annunciator and being difficult to remind other vehicle complex problem, provide following two kinds of schemes:

However, navigation software on the market is various at present, the difficulty of uniformly sending the early warning information is high, meanwhile, according to survey display, the vehicle coverage rate of the navigation software is low, and even if the early warning information can be uniformly sent through various navigation software, surrounding vehicles cannot be comprehensively informed to avoid.

Therefore, the current early warning mode is difficult to timely and accurately inform the surrounding vehicles of the traffic prompt information, so that the surrounding vehicles cannot effectively cooperate with the special vehicles to execute tasks, and the special vehicles are prevented from executing emergency tasks.

In order to solve the problem that an early warning mode in the prior art is difficult to timely and accurately inform surrounding vehicles of traffic prompt information, the application provides a road early warning system, a road early warning method, a first communication device and a second communication device.

The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a road early warning system 10 provided in the embodiment of the present application. The road warning system 10 includes: a first communication device 101 and a second communication device 102.

The first communication device 101 and the second communication device 102 are communicatively connected by a wireless communication link. The first communication device 101 is provided on a first vehicle, and the second communication device 102 is provided on traffic equipment on a roadside.

The second communication device is arranged on the traffic equipment on the roadside, and the vehicle driver needs to pay attention to the traffic equipment on the roadside all the time, so that the traffic information can be timely and accurately informed to the surrounding vehicles by the aid of the technical scheme.

In one possible implementation, the first vehicle further comprises a positioning device, and the first communication device 101 is connected to the positioning device.

The first communication device 101 may acquire the vehicle position of the first vehicle through the positioning device.

In one possible implementation, the first communication device 101 is further configured to determine a plurality of road control schemes according to the driving demand of the first vehicle.

Wherein the road control scheme is used to prompt driving behavior of a vehicle on a road. The second vehicle is another vehicle on the road than the first vehicle.

The first communication device 101 is further configured to determine a target road control scheme from a plurality of road control schemes.

The first communication device 101 is further configured to determine traffic guidance information according to the target road control scheme.

For example, the first vehicle may include the following two driving demands when passing through a certain road section: travel demand 1: selecting to pass through a lane on the inner side of the road; driving demand 2: the emergency lane passing from the road side is selected. The travel demand 1 needs to notify the peripheral vehicles on the road not to enter the inside of the road, and the travel demand 2 needs to notify the peripheral vehicles on the road not to stop in the emergency lane. The first communication device 101 may determine a plurality of road control schemes according to the travel demand of the first vehicle. For example, the road control scheme 1 is used to prompt a first vehicle to pass through a lane on the inner side of the road, and to prompt a surrounding vehicle not to drive into the inner side of the road. The road control scheme 2 is used for prompting that the first vehicle is about to pass through an emergency lane beside the road, and asking surrounding vehicles not to stop at the emergency lane.

The first communication device 101 may also determine a target road control scheme according to the two road control schemes described above. For example, the first communication device 101 determines the length of time for which the nearby vehicle executes the two road control schemes, and selects the road control scheme with the shortest time as the target road control scheme. The first communication device 101 determines traffic alert information according to the determined target road control scheme.

Wherein the preset mode comprises at least one of the following: changing the indication state of the traffic light and adjusting the duration of the traffic light.

Illustratively, when an ambulance needs to go straight through an intersection, a first communication device 101 on the ambulance sends a traffic alert to a second communication device 102. The traffic prompt information can be { ambulance, vehicle coordinates, crossroad ahead }. The second communication device 102 determines the traffic information of the road according to the traffic prompt information, sets the straight signal of the traffic signal lamp to be in a passable state according to the traffic information, and sets the signals in other directions to be in an impassable state so as to ensure that the ambulance can pass along the road. Alternatively, if the straight-ahead signal of the current traffic light is in a passable state, the second communication device 102 may extend the duration of the current signal state according to the passage information to ensure that the ambulance can pass along the road.

In one possible implementation, the traffic alert information includes at least one of a vehicle type of the first vehicle, a vehicle location of the first vehicle, and a driving scheme of the second vehicle.

In one possible implementation, the second communication device 102 further includes a display.

The second communication device 102 is used for controlling the display 1023 to display the traffic information.

Further, the display 1023 displays the traffic information by at least one of a text, an image, and an indicator lamp.

Illustratively, display 1023 may be a digital tube display. The display 1023 is capable of displaying a pattern of arrows. The traffic information may indicate that the vehicles around the road move to the side of the road. The display 1023 displays an arrow pointing to the road side according to the traffic information to instruct the nearby vehicle to move toward the road side.

Illustratively, the display 1023 may also be a Light Emitting Diode (LED) display screen. When the ambulance travels in the B lane of the A road in a certain direction, the second communication device 102 may control the display 1023 to display "the ambulance is traveling in the B lane of the A road in a certain direction, please pay attention to avoidance".

In a possible implementation, the traffic information further includes event information. The event information is used to notify the nearby vehicle of the currently occurring emergency.

Illustratively, a patient in an ambulance is urgently in need of O-type blood, and the traffic information may include event information indicating the patient is urgently in need of O-type blood. The second communication device 102 may control the display 1023 to display "ambulance on the current road is in urgent need of type O blood, please contact the hospital with a person who can provide assistance".

For example, when the police car is performing a dangerous task, the second communication device 102 may control the display 1023 to display "the vehicle with the number of AABBC carries dangerous goods and please pay attention to avoidance" through the road early warning system 10 provided in the present application.

In one possible implementation, the first vehicle may be a vehicle that performs a predetermined task or an authorized vehicle.

For example, the vehicle performing the preset task may be an ambulance, a fire engine, a police vehicle, an emergency work vehicle, etc. For the specific implementation, please refer to the above example, which is not described herein again.

When the first vehicle is an authorized vehicle, for example, a passenger in a common passenger car has a sudden illness, the driver of the vehicle may request the upper department to obtain temporary authorization, send a traffic prompt message to the second communication device 102 through the first communication device 101, the second communication device 102 determines the traffic information of the road according to the traffic prompt message, and control the display 1023 to display that "there is a sudden illness of the passenger in the passenger car traveling in a certain direction on the D lane of the B road, please avoid the D lane and call the staff who can provide help", and optionally, the traffic information may further include the contact way of the staff.
