Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First embodiment
Fig. 1 is a flowchart illustrating a vehicle control method according to a first embodiment of the present invention. For a clear description of the vehicle control method provided by the first embodiment of the present invention, please refer to fig. 1.
At present, a lot of vehicles often appear on a tunnel, an overhead high speed, run fast to consider that an accident happens in the front, but the situation that the vehicle is anchored and the like cannot be seen until the vehicle goes out of the tunnel and goes off the overhead high speed is commonly called as ghost traffic jam. In principle, the situation is not caused when everyone drives to the upper limit of the speed limit of high speed, high altitude and tunnel. So the cause of ghost traffic jam can be obtained: 1. with the vegetable bird, the speed limit is 80, and the new man dares to drive 40 or even less than 40, although the front side does not have the vehicle, the rear vehicle pile, such as the lane in the tunnel, is a solid line, and the lane changing cannot be followed. If the traffic flow is large, a lot of vehicle backlogs can occur until the vehicle backlogs out of the tunnel; 2. some people are distracted to drive, such as driving while playing a mobile phone, driving slowly, or changing lanes randomly, or riding on a line, so that the following car dares not to exceed the device or cannot exceed the device; 3. the people in front are slow to drive, vehicles are arranged around the people, and the vacancy is small, but in order to keep up with the past, the people also want to drill the vacancy, overtake and the like, and when the vehicles are overstocked, one vehicle changes lanes, the vehicles in the middle of the vehicle are blocked, and the vehicles in two lanes cannot walk. For the above reasons, in order to solve the technical problem of the ghost traffic jam in a targeted manner, a first embodiment of the present invention provides a vehicle control method, including the steps of:
step S1: and acquiring external environment information and a vehicle speed value, wherein the external environment information comprises front and rear vehicle information and speed limit information.
In one embodiment, the vehicle speed value is the current vehicle speed, and the obtaining of the vehicle speed value is simply to obtain the information of the vehicle itself, so a specific obtaining method may include, but is not limited to, obtaining the vehicle speed value through a can bus of the vehicle. The step of obtaining the external environment information can be obtained by the execution terminal of the method and an external information terminal establishing communication connection, such as a cloud terminal and a server, and the position information of the vehicle can be used as a standard in the obtaining process. Specifically, the implementation process may be that external environment information of the current location is acquired through the location information of the vehicle, where the external environment information includes front and rear vehicle information and speed limit information. The information about the front and rear vehicles may include relative speed information, relative distance information, vehicle density information within a preset distance range, and the like of the front and rear vehicles. It should be understood that the above is a simple illustration of the technology and is not a limitation on the technical solution.
In one embodiment, the vehicle control method further includes acquiring an image within a preset distance range behind the vehicle, and acquiring vehicle density information in the image by using an image recognition technology.
In one embodiment, an image within a preset distance range behind the vehicle is acquired, the vehicle density information in the image is acquired by using an image recognition technology, that is, the vehicle is provided with an image capturing device, such as an on-board camera, and the captured image of the environment behind the vehicle is analyzed by image recognition by acquiring a video or an image of the environment in front of the vehicle or behind the vehicle, so as to acquire corresponding information of the front vehicle and the rear vehicle.
In another embodiment, the method for acquiring information of vehicles in front of and behind may further include acquiring relative speed information, relative distance information, vehicle density information within a preset distance range, and the like of the corresponding vehicles in front of and behind by corresponding information acquiring devices, such as a laser device, a radar device, and the like, disposed in front of and behind the vehicle. In other embodiments, for all vehicles on the road in the car networking state, for example, all vehicles on the road commonly access to the same network, where the network may specifically include but is not limited to a bluetooth mesh network, a local area network, a wide area network attached to the same network platform, and the like, the related information of other vehicles in the same road area is received through the network, so as to obtain the vehicle-to-vehicle information.
Step S2: if the vehicle speed value is lower than the lower vehicle speed limit value in the speed limit information, and the information of the front vehicle and the rear vehicle accords with a preset road condition, vehicle control information is generated, the preset road condition comprises the condition that the relative distance between the preset road condition and the front vehicle is greater than a first threshold value, and the vehicle density in the preset distance range behind the vehicle exceeds a second threshold value, and the vehicle control information comprises driving reminding control information and vehicle driving control information.
In one embodiment, the speed limit information may specifically be not only a specific value, such as a speed value marked in a common road, for example 80 codes, but also a speed range, for example, 80-60 speed values. In step S2: if the vehicle speed value is lower than the vehicle speed lower limit value in the speed limit information, namely the speed range is preferably adopted as the speed limit information, wherein the vehicle speed lower than the vehicle speed lower limit value in the present example, namely the driving vehicle speed is not lower than 60 codes, and if the vehicle speed lower than 60 codes, the vehicle control provided by the application is triggered to avoid the ghost traffic jam risk. Furthermore, for the case that the speed limit information is a specific value, the adjustment may be performed according to a preset method, for example, the preset lower limit of the vehicle speed is 60% or 50% of the speed limit information, taking 50% as an example, when the speed limit information corresponds to 80 yards, the corresponding lower limit of the vehicle speed is 40 yards, that is, the vehicle speed should not be lower than 40 yards. It should be understood that the description processing of the actual situation of the speed limit information is not a technical limitation, and the actual situation may not be included in the above list, so that the adaptation may be performed according to the actual situation.
In one embodiment, in step S2, the condition for generating the vehicle control information includes "when the vehicle speed is lower than a threshold value in the speed limit information, and the information of the front and rear vehicles conforms to a preset road condition". The speed limit information is already explained, and the condition that the relative distance between the speed limit information and the front vehicle is greater than the first threshold value and the vehicle density in the preset distance range behind the vehicle exceeds the second threshold value is explained aiming at the preset road condition, namely the preset road condition corresponds to the condition that the current vehicle is or can cause ghost traffic jam. In summary, vehicle control is triggered when the vehicle speed is too low, which leads to a situation where ghost traffic jams occur. Furthermore, the explanation for the preset road condition can also be extended to the case where the density of vehicles in front of the vehicle is lower than the second threshold value, and the relative distance from the rear vehicle is lower than the first threshold value. And the above conditions can be combined at will as long as the conditions are enough to prove that the road in front of the vehicle is spacious and the congestion condition is generated or is about to be generated behind the vehicle. Furthermore, the preset distance range, the first threshold, the second threshold, etc. are not particularly limited, because the vehicle speed, the road condition and the limitation are complicated, for example, for a road which is relatively open, the above values are all larger, but for a road which is relatively congested, the above values become relatively smaller; similarly, the values are larger on roads with a higher speed limit information range, and become smaller on roads with a lower speed limit information range even if the road conditions are consistent or similar. That is, the technology is not limited to a specific value because the actual situation is complicated, and the technology will be described briefly.
In one embodiment, the step of generating the vehicle control information includes: and responding to the driving reminding control information, monitoring speed change information of the vehicle, and generating vehicle control information according to the speed change information, wherein the vehicle control information comprises the speed of the vehicle.
In one embodiment, as can be seen from the foregoing analysis of the ghost traffic jam, the ghost traffic jam is caused by the speed of the vehicle being too low, and therefore the vehicle control information is to realize the speed increase of the vehicle when the ghost traffic jam occurs or is already generated. The method specifically comprises the steps of responding to driving reminding control information, monitoring speed change information of the vehicle, and generating vehicle control information according to the speed change information.
In another embodiment, the vehicle control information may also include automatic driving control information. Specifically, the automatic driving control information not only includes control information for controlling the vehicle to increase the speed, but also includes, but is not limited to, obtaining the uniform speed driving control information according to the speed limit information, so as to control the vehicle to be capable of driving at a uniform speed in the road at an appropriate speed within the range of the speed limit information. The following control information or the leading control information can be obtained by obtaining the information of the front vehicle and/or the information of the rear vehicle. Aiming at the following control information, namely controlling the vehicle to keep a certain distance from the front vehicle and driving behind the front vehicle; and for the vehicle-leading control information, keeping a certain distance from the rear vehicle, and leading the rear vehicle to run in the road at a proper speed within the speed limit information range.
In one embodiment, the driving assistance control information includes: the manner in which the driving reminder is output and the frequency at which the driving reminder is output.
In one embodiment, it is understood that the major phenomena that the owner does not really drive or dares to drive at an increased speed or cause the ghost traffic jam can be analyzed in the explanation of the ghost traffic jam as described above. Therefore, when the vehicle cannot be controlled to speed up or automatically drive, the driver can be prompted or reminded correspondingly to inform the driver of increasing the vehicle speed and driving attentively, so as to prevent the ghost from traffic jam. Specifically, the output reminding mode may be to acquire image information of the driver through a camera device in the vehicle, analyze the behavior of the driver, and determine the corresponding situation, which is the case of distracted driving, such as playing a mobile phone or being inattentive, or the case of the driver driving seriously but causing the vehicle to run at a low speed due to some reason, such as the case of the driver being a bird, etc. Therefore, the driving state of the driver can be reminded in a targeted manner, and specifically, the reminding content can include but is not limited to that when the driver is in a distraction state, the reminding is "please the user to concentrate on driving, and the vehicle speed is too slow, and the speed can be increased by 50% appropriately". The prompt is performed according to a preset frequency, and the adjustment can be performed according to the speed appropriateness of the vehicle speed value, for example, for the case of a low speed, the frequency may not be so fast, and the like. In one embodiment, after the number of times of reminding exceeds a certain number, the driver still does not speed up, and can output warning information, for example, the driver can remind the driver according to the frequency of reminding once per minute before, and directly output the warning information for the third time, namely, within one minute, the driver can actively stop the vehicle without putting down the mobile phone.
In one embodiment, the driving alert control information may be coordinated with the vehicle control information. As mentioned above, when the driving reminding control information with the warning content is output and the driver does not cooperate to speed up, the vehicle machine CAN be used for sending the CAN signal to open the double jump and control the vehicle to slow down the speed and stop at the side. Specifically, the driver's noncompliance may include, but is not limited to, driver distraction, for example, the driver neglects to play a mobile phone to give a prompt, or the driver may have a health problem such as a disease accident or the vehicle may have a control problem and cannot control the vehicle. Furthermore, for the condition that the driver is distracted, the warning content of 'putting down the mobile phone to restart the vehicle, or contacting 110 after 5 minutes' can be output through the vehicle-mounted display, so that the driver can be prompted to pay attention to driving as soon as possible; for the latter, the driver cannot control the vehicle, and subsequent operations can be correspondingly performed, for example, medical staff can be contacted when the driver breaks a disease, and maintenance staff can be contacted when a control problem occurs to the vehicle. The foregoing is merely illustrative of the technology and is not limiting.
And step S3: and controlling the vehicle according to the vehicle control information.
In one embodiment, step S3 is an execution subject that executes a corresponding response according to the vehicle control information to complete the control of the vehicle. Specifically, the response mode and the response operation have been described in detail in the foregoing description of various types of vehicle control information, and reference may be made to the foregoing expressions, which are not described herein again.
A vehicle control method according to a first embodiment of the present invention includes the steps of: step S1: acquiring external environment information and a vehicle speed value, wherein the external environment information comprises front and rear vehicle information and speed limit information; step S2: if the vehicle speed value is lower than the lower vehicle speed limit value in the speed limit information, and the information of the front vehicle and the rear vehicle accords with a preset road condition, generating vehicle control information, wherein the preset road condition comprises the condition that the relative distance between the front vehicle and the rear vehicle is greater than a first threshold value, and the vehicle density in a preset distance range behind the vehicle exceeds a second threshold value, and the vehicle control information comprises driving reminding control information and vehicle driving control information; and step S3: and controlling the vehicle according to the vehicle control information. Therefore, when the vehicle can cause the situation of ghost traffic jam, the vehicle can be controlled in time to avoid the situation of ghost traffic jam, the vehicle speed is increased while the safety of a driver is guaranteed to the greatest extent, the road smoothness is improved through public driving order, the operation of a user is reduced, the convenience of the user is improved, and the use experience of the user is improved.
