Description
Technical Field
The invention relates to the field of vehicle driving assistance, in particular to the field of related prompt control during vehicle driving assistance.
Background
With the development of economy, particularly the development of the automobile industry, the number of automobiles in the society is more and more at present, along with the improvement of the living standard of people, the automobiles are very popular as walking tools, the configuration requirements of consumers on the automobiles are higher and higher when the consumers buy the automobiles, but the common automobile configuration in the market at present can not meet the requirements of the consumers on the humanization and the intellectualization of the automobiles. In particular, the current vehicle operation tends to be automated to assist the driver in driving, so that the driver can drive more easily.
For example, an Advanced Driver Assistance System (ADAS), which is an active safety technology that collects environmental data inside and outside a vehicle at the first time by using various sensors mounted on the vehicle, and performs technical processes such as identification, detection, and tracking of static and dynamic objects, so that a Driver can detect a possible danger at the fastest time to draw attention and improve safety.
According to the definition of the Wikipedia online encyclopedia, the current advanced driving assistance systems generally include a navigation and real-time traffic system TMC, an electronic police system ISA (Intelligent speed adaptation or interactive speed), a vehicle networking (Vehicular communication systems), an adaptive cruise control (acc), a Lane departure warning system (ldws), a Lane keeping system (Lane keep), a Collision avoidance or Pre-Collision system (Collision avoidance or Pre-crash system), a Night Vision system (Night Vision system), adaptive light control (Adaptive light control), Pedestrian protection system (Pedestrian protection system), automatic parking system (automatic parking), Traffic sign recognition (Traffic sign recognition), Blind spot detection (Blind detection), Driver fatigue detection (Driver fatigue detection), downhill control system (hill detection control), and Electric vehicle warning (Electric vehicle warning) system.
It can be seen that although there are many functional driving assistance systems, they cannot be used to assist the driver to comply with increasingly complex regulations in China.
With the construction of cities and the development of public transportation, the reduction of traffic congestion inevitably becomes the key work for the development of each city. In order to scientifically improve road passing efficiency and slow down traffic pressure, a restricted road is defined in different areas by a plurality of cities according to a vehicle flow rule. And the penalty measures such as fine and deduction are taken for the vehicles which do not comply with the regulations. Most drivers cannot intentionally violate the traffic control area, but due to the limitation of human eyes and attention, particularly when driving into a strange city, the drivers can enter the traffic control area carelessly because the drivers can judge whether the road ahead is the traffic control road by observing the front signboard, the road characters and the line by eyes in the traditional mode. Due to the sight line obstruction and the negligence of people caused by the front cart, tree leaves and the like, the observation and judgment of people are usually not careful by only depending on the observation and judgment of the people. Although many vehicles are also provided with navigation systems, the navigation systems are difficult to accurately remind drivers in time because the urban restricted roads, time intervals and the like can change at any time or the restricted information cannot be updated into corresponding navigation map information in time. Therefore, drivers sometimes carelessly drive vehicles into restricted areas, and the drivers are stressed by urban traffic and lose themselves.
Therefore, there is a need for a driving assistance method, device and system, which can help a driver to obtain a prompt of traffic restriction information at the first time, so as to make a driving road selection in advance, avoid entering a traffic restriction road, relieve urban traffic pressure, and reduce loss brought to the driver.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
As described above, the present invention provides a driving assistance method, and referring to fig. 1, fig. 1 shows a flowchart of the driving assistance method provided by the present invention.
As shown in fig. 1, the driving assistance method provided by the present invention includes step 101: acquiring a front road image of a vehicle; step 102: identifying whether the front road image contains the restriction information of the road; and in response to the road image ahead containing the restriction information, executing step 103: the output control signal controls the interactive device to output prompt information related to the restriction information.
Specifically, in step 101, an image of the road ahead of the vehicle may be acquired by the camera module. For example, the front of the vehicle can be photographed by a front-mounted camera.
In one embodiment, since the traffic restriction information of the road can be generally drawn on the road surface of the road through the road marking paint, for example, the setting of the bus lane, the traffic restriction time of the bus lane, and the like, the road surface can be photographed by arranging the front vehicle-mounted camera to obtain the road surface image of the road.
In another embodiment, since the restriction information of the road can be generally indicated by road sign signs, such as signs set up on both sides of the road for no-pass, one-way lanes, etc., or signs set up on highways, elevated roads, etc., both sides of the road can be photographed by setting up a front-mounted vehicle-mounted camera to obtain images of both sides of the road.
In another preferred embodiment, the road surface image and the road side image of the front road can be acquired simultaneously by setting a wide-angle front-mounted vehicle-mounted camera, so that the front road image can be acquired more comprehensively. Further, the front camera of the vehicle may be arranged to acquire road images in front including at least road images 80 meters in front. Therefore, the relevant restriction information of the road ahead can be acquired as early as possible, so that the driver can be informed of the restriction information in time, and the driver is given sufficient time to select a proper road.
In step 102, the restriction information of the road required to be identified in the front road image further includes a restriction mark, a restriction letter, or a combination of both. It should be understood by those skilled in the art that the restriction information usually set on the road may be represented in the form of a picture mark, and at the same time, some restriction information is represented in the form of characters or numbers, so that it is possible to identify whether the front road image contains the restriction information of the road by performing picture similarity comparison, character recognition, or a combination of the two on the front road image obtained in step 101.
In one embodiment, step 102 may be implemented by applying a visual algorithm to recognize the limited-travel text and the logo, wherein the text is primary and the logo is secondary. Any restricted road can be informed to a great number of drivers in advance in a text mode through a guideboard or a display screen. The camera module shoots the prompting content of the limited driving and inputs the prompting content into the processor for comparison processing, and relevant limited driving content is identified and the driver is reminded.
In step 103, in response to identifying the restriction information in the front road image, the output control signal controls the interaction device to output prompt information related to the restriction information.
In one embodiment, the interaction device may be controlled to visually output the prompt message within a driver's field of view of the vehicle. Specifically, the interactive device capable of visually outputting the prompt message includes, but is not limited to, an on-vehicle dashboard, a center console, a front windshield equipped with a head-up display function, and the like.
Preferably, in an embodiment, the prompt message may be output by controlling the head-up display device. Generally, a driver needs about 0.3 to 1 second to raise his Head or turn to see other display screens, and the raising display (i.e. Head-up display) enables the driver to look ahead at the Head, so that the time can be saved, the driver is prevented from being distracted by lowering his Head (looking at instruments) or turning his Head (looking at a central control display screen, etc.), and related warnings can be transmitted to the driver at a higher speed.
In another embodiment, the interactive device is controlled to output the prompt message by hearing, and in particular, the interactive device capable of outputting the prompt message by hearing includes, but is not limited to, a car audio and the like. The driver is prompted in an auditory mode, the reaction time of the driver can be saved, the driver is prevented from being distracted by lowering the head (watching an instrument) or turning the head (watching a central control display screen and the like), and related warnings can be transmitted to the driver at a higher speed.
Furthermore, the prompt information related to the traffic restriction information further includes one or more of whether the road ahead is restricted, the type of the traffic restriction, and the time of the traffic restriction. With the development of economic society, people's living standard is higher and higher, and vehicles on roads are more and more, so, in order to alleviate traffic pressure, the restriction rule in China is more and more complicated at present. Sometimes, even if a driver knows that a restriction may exist on a road section ahead, the specific restriction time and restriction type (such as a single or double number of a license plate) are unclear, and if the driver is allowed to carefully check the restriction rule set on the road, the driver may be distracted, so that in the driving assistance method provided by the invention, the output prompt information can be specific to whether the restriction, the restriction type, the restriction time and the like are related to the restriction information, the driver can know the restriction condition of the road ahead more intuitively and laborsavingly, and can make a decision more timely whether to continue the form or change the line.
Outputting the prompt information related to the restriction information is particularly friendly to novice drivers or drivers who drive across provinces. The novice driver is easy to ignore possible restriction marks on the road due to poor experience, or even if seeing the restriction marks, the restriction rules corresponding to the restriction marks are not clear, and the traffic laws are easy to violate. Drivers driving across provinces and different places can not know the restriction rules corresponding to the restriction marks because of unfamiliarity with the different restriction marks of different provinces, and violation is easily caused. According to the driving assistance system provided by the invention, the recognized traffic control information can be converted into a concise traffic control rule, the traffic control condition of a road in front of a driver is directly and reasonably informed, and the driver can make a decision in time to continue to form or change a route.
According to the driving assistance method provided by the invention, the relevant restriction information about the road can be obtained at the first time by acquiring and identifying the road image in front of the vehicle, and the driver is informed in time to be reminded at the first time, so that the selection of the driving road is made in advance, the road can be prevented from entering the restriction road, the urban traffic pressure is relieved, and the loss brought to the driver is reduced.

Moreover, the driving assistance device 200 provided by the present invention may be a terminal device located in a vehicle, wherein the processor 201 may be only a local processor, or even if the processor 201 has a function of connecting to a cloud, the processor 201 does not need to use the function of connecting to the cloud when executing a computer program to implement the driving assistance method described above.
Since the processor 201 does not need to be connected to the cloud, the processor 201 executes the computer program locally to implement the driving assistance method described above, so that the time for the processor 201 to communicate with the cloud can be saved, and the time required for the processor 201 to implement the driving assistance method described above can be reduced. Because the processor 201 does not need to communicate with the cloud end for implementing the driving assistance method, and the time for executing the computer program to complete the processing is millisecond-level, the traffic restriction information can be output at a higher speed, and the effect of timely reminding the driver of paying attention is achieved, so that the driver has more sufficient time to select the relevant road.
The invention also provides a driving assistance system, which at least comprises the driving assistance device 200, the camera module 300 and the interactive interface 400. The driving assistance apparatus 200 includes a processor 201 and a memory 202. The processor 201 of the driving assistance device 200 can implement the driving assistance method described above when executing the computer program stored in the memory 202, and please refer to the description of the driving assistance method, which is not described herein again.
The driving assistance device 200 provided by the present invention may be a terminal device located in a vehicle, wherein the processor 201 may be only a local processor, or even if the processor 201 has a function of connecting to a cloud, the processor 201 does not need to apply to the function of connecting to the cloud when executing a computer program to implement the driving assistance method described above.
Since the processor 201 does not need to be connected to the cloud, the processor 201 executes the computer program locally to implement the driving assistance method described above, so that the time for the processor 201 to communicate with the cloud can be saved, and the time required for the processor 201 to implement the driving assistance method described above can be reduced. Because the processor 201 does not need to communicate with the cloud end for implementing the driving assistance method, and the time for executing the computer program to complete the processing is millisecond-level, the traffic restriction information can be output at a higher speed, and the effect of timely reminding the driver of paying attention is achieved, so that the driver has more sufficient time to select the relevant road.
Specifically, the camera module 300 may be a front camera disposed on a vehicle, and controls a shooting angle thereof to cover a road surface and/or two sides of a road ahead, so as to acquire an image of the road ahead.
