Problems solved by technology

[0002] As the number of cars increases year by year, there are more and more cars on the road. On the expressway, the traffic flow is too large, the speed is fast, and the distance is small. Accidents can cause serial rear-end collisions of dozens of vehicles, resulting in heavy casualties, heavy losses, and severe congestion, especially on curves and downhill roads. Drivers have poor sightlines or cannot stop in an emergency. Often, they cannot deal with the accident in a timely and effective manner after the car stops. rear-end collision
[0003] The current practice is that when a car has a rear-end collision on a highway or cannot be moved away immediately, the driver must call the police immediately, and at the same time place a triangle warning sign 100-200 meters behind the car to evacuate people and quickly evacuate Highway, so there are several problems: 1. It is often difficult to get through the call to the police. Sometimes the mobile phone cannot be found after a car accident. Location of car accident, delayed rescue time
2. It takes time to find the tripod. It is very dangerous to walk to the rear of the car with the tripod. Often, you are not injured in an accident, but you are hit by the car behind when you place the tripod. Low, it is not easy to attract the attention of oncoming vehicles, and it is too late when the oncoming vehicle is running fast enough to see the tripod, so we can only adopt sudden braking, which causes serial rear-end collisions of vehicles behind
3. The driver usually stands near the car to call the police, and looks around to determine the location, which is easy to distract and cause collision avoidance.
The system uses the public telephone network to form an early warning network. Since the artificial signal switch is used to replace the sensor and other monitoring devices, it is impossible to monitor and warn the vehicle rear-end collision. Pre-warning the occurrence of rear-end collision accidents, so as to prevent rear-end collision accidents

Embodiment 1

[0039] The present embodiment provides a highway safety driving warning system, such as figure 1 shown, including:

[0040] Detection module 11, is used for detecting the information of traveling vehicle in real time;

[0041] The first judging module 12 is used to judge whether the inter-vehicle distance between two adjacent workshops is a safe driving distance;

[0042] The second judging module 13 is used to judge whether the speed difference between two adjacent vehicles is greater than a safety value;

[0043] The warning module 14 is used for sending warning information to the vehicle.

[0044] In this embodiment, it also includes a radio frequency communication module and a vehicle-mounted device; the radio frequency communication module communicates with the vehicle-mounted device in two-way wireless communication; the vehicle-mounted device is placed in the vehicle; the radio frequency communication modules are equidistantly arranged on the highway On the isolation...

Embodiment 2

[0091] A kind of expressway safety driving warning system of this embodiment differs from Embodiment 1 in that:

[0092] Such as Figure 4 As shown, in this embodiment, it is assumed that the vehicle C1 is currently in the second radio frequency communication module M i+2 The position of the on-board device in the vehicle C1 and the second radio frequency communication module M i+2 Two-way wireless communication (i≥1), and the speed of C1 is the normal speed. The safe distance between the vehicle C1 and the rear vehicle C2 is the second radio frequency communication module M i+2 To the second radio frequency communication module M idistance, the safe distance between the vehicle C1 and the front vehicle C3 is the second radio frequency communication module M i+2 To the second radio frequency communication module M i+4 distance.

[0093] It should be pointed out that each second radio frequency communication module communicates through a mobile public network wireless com...

Embodiment 3

[0134] A kind of expressway safety driving warning system of this embodiment differs from Embodiment 1 in that:

[0135] In this embodiment, if the current vehicle is a large truck, the lane information obtained is that it is in the overtaking lane. If the current road section position does not allow large trucks to enter the overtaking lane, one or more of sound, vibration, and light will be used to prompt, thereby alerting the driver.

[0136] If the current vehicle is an ambulance and the obtained lane information indicates that it is in the emergency lane, no prompt will be given.

[0137] In practical application, it is not limited to the driving conditions proposed in this embodiment, and many situations are not difficult to analyze on the basis of the technical solutions disclosed in this embodiment, so details will not be repeated here.

[0138]In this embodiment, according to different types of vehicles, different road sections on expressways, different expressways, ...

Abstract

The invention discloses a highway safe driving warning method and system. The invention relates to a highway safe driving warning system, comprising a detecting module for detecting the information of a driving vehicle in real time; a first determining module for determining whether a distance between two adjacent vehicles is a safe driving distance; a second determining module for determining whether a difference between the speeds of the two adjacent vehicles is greater than a safe value; and a warning module for sending a warning message to the vehicle. The system can detect the information of the driving vehicle in real time, including vehicle speed, lane information and the like, thereby monitoring the vehicle in the whole process and promptly reminding a driver.

technical field [0001] The invention relates to the technical field of traffic management, in particular to an expressway safety driving warning method and system. Background technique [0002] As the number of cars increases year by year, there are more and more cars on the road. On the expressway, the traffic flow is too large, the speed is fast, and the distance is small. Accidents can cause serial rear-end collisions of dozens of vehicles, resulting in heavy casualties, heavy losses, and severe congestion, especially on curves and downhill roads. Drivers have poor sightlines or cannot stop in an emergency. Often, they cannot deal with the accident in a timely and effective manner after the car stops. Causing multiple vehicles to rear-end. [0003] The current practice is that when a car has a rear-end collision on a highway or cannot be moved away immediately, the driver must call the police immediately, and at the same time place a triangle warning sign 100-200 meters ...
