[0023] The technical solution of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0024] The embodiments of the present application provide a driving assistance system.
[0025] Figure 1 It is a structural block diagram of a driving assistance system according to a preferred embodiment of the present application. As Figure 1 shown, the driving assistance system includes a lighting module 1, a vehicle detection module 2, and a control module 3.
[0026] When the lighting module 1 is turned on, it irradiates on the markings for indicating dangerous driving areas. According to the position of the markings, by adjusting the angle of the light emitted by the lighting module 1, the lighting module 1 irradiates on the markings. In addition, in the embodiment of the present application, the dangerous driving areas can be sections such as tunnels, curves, mountain roads, etc. that can increase the danger of driving. Additionally, there are many power supply methods for the lighting module 1. For example, it can be directly powered by the power system. For another example, it can be powered by solar energy or wind energy generation.
[0027] Optionally, in the embodiment of the present application, the number of the lighting modules 1 can be determined according to specific circumstances. Specifically, multiple lighting modules 1 can be arranged along the driving direction of the vehicle.
[0028] The vehicle detection module 2 is used to send an identification signal when it detects that the vehicle is at a first preset distance from the dangerous driving area. The identification signal is used to identify that the vehicle is at the first preset distance from the dangerous driving area. In the embodiment of the present application, the first preset distance can be determined according to specific circumstances and will not be limited herein.
[0029] In addition, in the embodiment of the present application, the vehicle detection module 2 can include any component that can send an identification signal when the vehicle is at the first preset distance from the dangerous driving area. For example, the vehicle detection module 2 can include a distance sensor. Additionally, the installation position of the vehicle detection module 2 can be determined according to specific circumstances as long as it can send an identification signal when the vehicle is at the first preset distance from the dangerous driving area. For example, if the vehicle detection module 2 is a distance sensor and the dangerous driving area is a tunnel, the distance sensor can be installed at the entrance of the tunnel.
[0030] The control module 3 is configured to control the lighting module 1 to turn on when receiving an identification signal. In the embodiments of the present application, the way for the control module 3 to control the lighting module 1 to turn on can be determined according to specific circumstances. For example, it can be to control the lighting module 1 to be constantly on. Or, it can be to control the lighting module 1 to alternate between bright and dark. Specifically, it can be to control the lighting module 1 to turn on for a first preset time and then turn off, and turn on again after the lighting module 1 has been off for a second preset time, so as to control the lighting module 1 to alternate between bright and dark. Herein, the units of the first preset time and the second preset time are seconds. The specific values of the first preset time and the second preset time can be determined according to specific circumstances. For example, the first preset time can be 2 seconds, 3 seconds, etc. For another example, the second preset time can be 1 second, 2 seconds, etc. By controlling the lighting module 1 to alternate between bright and dark, the lighting module 1 can blink, thereby further enhancing the warning effect.
[0031] Optionally, in the embodiments of the present application, the control module 3 is further configured to control the lighting module 1 to turn off when receiving two identification signals in succession and the time interval between the two consecutive received identification signals is within a preset time range. In this way, when the vehicle leaves the dangerous driving area, the lighting module 1 can be controlled to turn off to save energy.
[0032] Specifically, along the direction of vehicle travel, the dangerous driving area has two ends, and vehicle detection modules 2 can be provided at both ends. In this way, when the vehicle travels along a certain driving direction and approaches the dangerous driving area, it can trigger the vehicle detection module 2 at one end of the dangerous driving area to send out an identification signal; when leaving the dangerous driving area, it can trigger the vehicle detection module 2 at the other end of the dangerous driving area to send out an identification signal. If the control module 3 receives two identification signals in succession and the time interval between the two consecutive received identification signals is within a preset time range, it indicates that the vehicle has left the dangerous driving area. In this case, the lighting module 1 can be controlled to turn off to save energy.
[0033] In the embodiments of the present application, the preset time range can be determined according to specific circumstances. For example, it can be set according to the time taken by the vehicle to pass through the dangerous driving area.
[0034] Optionally, in the embodiments of the present application, the vehicle detection module 2 can include a ground sense coil. The ground sense coil is arranged at a position at a first preset distance from the dangerous driving area.
[0035] Specifically, along the vehicle travel mode, the ground sense coil is arranged at a position at a first preset distance from the dangerous driving area. When the vehicle passes through the ground sense coil, the ground sense coil sends out an identification signal.
[0036] Optionally, in the embodiments of the present application, the vehicle detection module 2 may include a camera and a video analysis module. The camera is disposed at a certain distance from the ground and captures the position at a first preset distance from the dangerous driving area. The video analysis module is configured to determine whether there is a vehicle at a first preset distance from the dangerous driving area based on the video captured by the camera; and issue an identification signal when it is determined that there is a vehicle at a first preset distance from the dangerous driving area.
[0037] Optionally, in the embodiments of the present application, the vehicle detection module 2 may include an inductive loop, a camera, and a video analysis module. In this way, including two components capable of detecting vehicles can ensure that one works properly when the other is damaged, thus ensuring the normal operation of the driving assistance system.
[0038] As Figure 2 shown, an inductive loop is disposed at a position at a first preset distance from the tunnel entrance, and a camera is provided to capture the position at a first preset distance from the tunnel entrance.
[0039] Optionally, in the embodiments of the present application, the camera may be disposed at a certain height from the ground, such as Figure 5 or Figure 6 shown. Being at a certain height from the ground can prevent water splashing and avoid damaging the camera.
[0040] Optionally, in the embodiments of the present application, along the direction of vehicle travel, the lighting module is disposed on one or both sides of the dangerous driving area.
[0041] Optionally, in the embodiments of the present application, the lighting module 1 may include LED lights and / or laser lights. It should be noted that when the lighting module 1 includes LED lights and laser lights, the number of LED lights and laser lights provided may be determined according to specific circumstances.
[0042] As Figure 2 shown, along the direction of vehicle travel, laser lights or LED lights are disposed on both sides of the tunnel. As Figure 3 or Figure 4 shown, laser lights or LED lights are disposed on the columns of the crash barrier, and the light of the laser lights or LED lights shines on the marking line. And / or, the laser lights or LED lights are made into laser light strips or LED light strips, and the laser light strips or LED light strips are attached to the inner wall of the tunnel, such as Figure 5 shown.
[0043] Optionally, in the embodiments of the present application, on one side of the dangerous driving area, a plurality of lighting modules 1 are arranged at equal intervals. It should be noted that if the lighting module 1 is only arranged on one side of the dangerous driving area, then when arranging a plurality of lighting modules 1 on this side, they are arranged at equal intervals; if the lighting module 1 is arranged on both sides of the dangerous driving area, then when arranging a plurality of lighting modules 1 on each side, they are arranged at equal intervals. Among them, the interval distance can be determined according to specific circumstances.
[0044] As Figure 2 shown, the laser lights or LED lights are arranged on both sides of the tunnel and are arranged at equal intervals, and the interval distance is 10 meters.
[0045] In addition, in the embodiments of the present application, the maximum diameter of the pattern formed by the light beam of the lighting module 1 irradiating the ground can be adjusted by adjusting the distance between the lighting module 1 and the ground. For example, the maximum diameter can be 2 meters, 3 meters, and so on.
[0046] Optionally, in the embodiments of the present application, the area where the lighting module 1 is arranged can be set. For example, it can be determined according to the specific situation of the dangerous driving area. As Figure 2 shown, the dangerous driving area is a tunnel, and the area where the lighting module 1 is arranged is determined by the length of the tunnel.
[0047] Optionally, in the embodiments of the present application, the laser lights or LED lights can use flexible LED light strips or flexible laser light strips to prevent glare.
[0048] Figure 6 It is a logical schematic diagram of a driving assistance system according to a preferred embodiment of the present application. Figure 6 The driving assistance system shown is described by taking a tunnel as an example. Among them, the settings of the camera, the ground induction coil, and the laser lights or LED lights can be referred to Figures 2 - 5 shown. It should be noted that in the embodiments of the present application, the vehicle detection module includes a ground induction coil, a camera, and a video analysis module. The video analysis module can be any device that can analyze whether there is a vehicle in the video based on the captured video.
[0049] When a vehicle passes over the inductive loop, the inductive loop transmits an identification signal to the control module 3. When the video analysis module analyzes that there is a vehicle passing in the video captured by the camera, it transmits an identification signal to the control module 3. In this embodiment, the control module 3 is a control cabinet. Among them, the control cabinet includes a communication switch, a video optical terminal and an optical fiber terminal box, a traffic signal controller, etc. The communication switch receives the identification signal and transmits it to the video optical terminal and the optical fiber terminal box; the video optical terminal and the optical fiber terminal box analyze the received identification signal and transmit the analysis content corresponding to the identification signal to the traffic signal controller; the traffic signal controller transmits an instruction through the communication switch according to the received analysis content corresponding to the identification signal to control the laser lamp or the LED lamp to turn on. Among them, the laser lamp or the LED lamp here includes the laser lamp or the LED lamp of the road section (installed on the column) and the laser lamp strip or the LED lamp strip installed on the inner wall of the tunnel, as Figure 6 shown.
[0050] In addition, when the traffic signal controller receives the analysis content corresponding to the identification signal twice in a row and the time interval between the two consecutive receptions of the analysis content is within the preset time range, in other words, the control module 3 receives the identification signal twice in a row and the time interval between the two consecutive receptions of the identification signal is within the preset time range, it means that the vehicle has left, and the control closes the laser lamp or the LED lamp. Specifically, the traffic signal controller transmits an instruction through the communication switch to control the laser lamp or the LED lamp to turn off. When the vehicle leaves, the power supply for the communication switch is turned off.
[0051] In addition, in the embodiment of the present application, power lightning protection and signal lightning protection can be set for the control cabinet.
[0052] In addition, in the embodiment of the present application, a second mobile device APP can also be included. The second mobile device APP is installed on the mobile device used by the driver. When the analysis content corresponding to the identification signal is detected, the traffic signal controller transmits a signal to the second mobile device APP to control the second mobile device APP to turn on the response mode, so that the second mobile device APP reminds the driver that they are about to enter the tunnel.
[0053] Optionally, in the embodiment of the present application, the driving assistance system can also include a sound prompt module. The sound prompt module is used to emit a sound for prompting; among them, the control module 3 is also used to control the sound prompt module to emit a sound when receiving the identification signal.
[0054] Specifically, at a position of a third preset distance from the dangerous driving area, a sound prompt module is set. Optionally, the third preset distance is less than the first preset distance.
[0055] Optionally, the sound prompt module can be a speaker.
[0056] Optionally, in the embodiments of the present application, the assisted driving system may further include a first mobile device APP. The first mobile device APP is installed on the mobile device of the driver. The first mobile device APP is used to give a prompt when it is detected that the vehicle is at a second preset distance from the dangerous driving area. Herein, the second preset distance may be the same as or different from the first preset distance, and there is no limitation on the magnitude relationship between the first preset distance and the second preset distance.
[0057] Specifically, the first mobile device APP can determine the position of the vehicle through the GPS positioning system, determine the distance from the dangerous driving area according to the determined position of the vehicle, and give a prompt when it is determined that the distance of the vehicle from the dangerous driving area reaches the second preset distance. For example, the prompt can be given by making the mobile device emit a sound or vibrate.
[0058] In addition, it can also be that a device is set at a position of the second preset distance from the dangerous driving area to be able to emit a Bluetooth signal or a wifi signal. When the first mobile device APP can successfully connect to the Bluetooth signal or the wifi signal, it indicates that the vehicle is at the second preset distance from the dangerous driving area, and the first mobile device APP gives a prompt.
[0059] Through the technical solution provided by the embodiments of the present application, by using the lighting module to irradiate the marking line, the warning effect of the marking line is strengthened, and traffic accidents caused by not being able to see the marking line or seeing the marking line unclearly are avoided. For example, when a driver is driving at night, or when the visibility is insufficient, or when the daytime light is insufficient, or when driving against the light on a mountain road during the day with sufficient light, or when entering a tunnel, traffic accidents to a certain extent or very serious traffic accidents will occur due to insufficient lighting conditions resulting in not being able to see or seeing the marking line unclearly. Using the technical solution provided by the embodiments of the present application can enable the driver to clearly see the marking line, strengthen the warning effect, effectively remind the driver to increase vigilance, remind the driver to pay attention to safety, increase driving safety, and achieve the improvement of road driving safety. In addition, in the case where the marking line is worn, using the technical solution provided by the embodiments of the present application can enhance the reflection effect of the marking line, enable the driver to see the marking line, strengthen the warning effect, effectively remind the driver to increase vigilance, remind the driver to pay attention to safety, increase driving safety, and achieve the improvement of road driving safety.
[0060] In addition, through the technical solution provided by the embodiments of the present application, when there is no vehicle or the vehicle is very far away, it does not work. When the vehicle enters the working range, the lighting module is automatically turned on for visual reminder and induction, without generating large expenses, and can effectively improve the safety effect.
[0061] The preferred embodiments of the present application have been described in detail above. However, the present application is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present application, various simple modifications can be made to the technical solutions of the present application, and these simple modifications all fall within the protection scope of the present application.
[0062] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present application will not separately describe various possible combination methods.
[0063] Furthermore, any combination can be made between various different embodiments of the present application, as long as it does not violate the idea of the present application, and it should also be regarded as the content disclosed by the present application.
