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, ...
