Detailed Description
Aiming at the problem that the vehicle cannot be effectively controlled in time in the prior art, the embodiment of the invention provides a vehicle-mounted terminal, a method for remotely controlling vehicle braking and a system thereof, and the main implementation principle, the specific implementation process and the corresponding beneficial effects of the embodiment of the invention are elaborated in detail by combining the attached drawings of the specification.
Fig. 1 shows a system structure of a remote control vehicle according to an embodiment of the present invention, which includes a service control center 100 and a vehicle-mounted terminal 200, where the service control center 100 and the vehicle-mounted terminal 200 may communicate with each other through a wireless network. The in-vehicle terminal 200 may be identified by an ID, and may have a function of detecting the speed and position of the vehicle. The in-vehicle terminal 200 may be installed in a hidden location in a vehicle to prevent intentional removal or damage.
In the network architecture shown in fig. 1, when receiving a control request from a user for a specific vehicle or determining that a driving prohibition condition preset for the specific vehicle is satisfied, the service control center 100 obtains a state of the specific vehicle and takes a corresponding measure according to the obtained state of the vehicle. For example, it is determined whether the vehicle meets a preset immediate braking condition according to the obtained vehicle state, and when the vehicle meets the condition, the on-board terminal 200 on the vehicle is instructed to control the vehicle to brake immediately, and when the vehicle does not meet the condition, the on-board terminal 200 on the vehicle is instructed to control the vehicle to reduce the vehicle speed.
If the instruction sent by the service control center 100 is an instruction for controlling the vehicle to brake immediately, the vehicle-mounted terminal 200 may brake the vehicle immediately by controlling a brake system of the vehicle; if the instruction sent by the service control center 100 is an instruction for controlling the vehicle to reduce the vehicle speed, the vehicle-mounted terminal 200 may gradually reduce the vehicle speed until the vehicle stops by controlling an oil supply system of the vehicle.
The vehicle state obtained by the service control center 100 may be a current vehicle speed of the vehicle, and specifically, the service control center 100 may instruct the vehicle-mounted terminal 200 on the vehicle to determine the vehicle speed of the vehicle in which the vehicle-mounted terminal 200 is located, and receive the vehicle speed information reported by the vehicle-mounted terminal 200. The vehicle-mounted terminal 200 detects the current speed of the vehicle according to the instruction of the service control center 100, or positions the position of the vehicle before and after the set time interval, so as to obtain the motion track of the vehicle, and calculates the speed of the vehicle according to the moving distance of the vehicle in the set time interval. Accordingly, the preset immediate braking condition may be: the vehicle speed of the vehicle is less than a set threshold value, such as: 30 km/h.
The vehicle state obtained by the service control center 100 may include, in addition to the vehicle speed, a road section condition corresponding to the position of the vehicle, for example, the road section where the vehicle is located is a normal road or an expressway, and is a congested road or an open road. Accordingly, the preset immediate braking condition may be: the speed of the vehicle is less than a set threshold and the condition of the road segment in which the vehicle is located allows the vehicle to brake immediately. In general, when a vehicle is traveling on a normal road or an open road and the speed is lower than a predetermined safe speed per hour, safety problems such as a rear-end collision of the vehicle are not generally caused by immediate braking, and therefore, the vehicle in the road condition can be immediately braked and timely controlled. In view of safety, when a vehicle is traveling on a highway or a congested road, immediate braking of the vehicle may cause traffic accidents such as rear-end collision of the vehicle, so it is not desirable to immediately brake the vehicle in the condition of the road. The road section condition of the position of the vehicle can also comprise road section traffic conditions and other conditions, such as whether the vehicle is a forbidden zone or not.
In the above process, when the service control center 100 needs to determine the road condition corresponding to the location of the vehicle, the location of the vehicle needs to be obtained first, specifically, the location of the vehicle is determined by sending a location positioning instruction to the vehicle-mounted terminal 200 on the vehicle, and if the location information reported by the vehicle-mounted terminal cannot be obtained due to the fact that the vehicle-mounted terminal 200 on the vehicle is not in the service area, the location of the vehicle where the vehicle-mounted terminal 200 is located may be further determined by sending the terminal identifier corresponding to the vehicle-mounted terminal 200 on the vehicle to the location service system. The service control center 100 may also directly instruct the location service system to locate the location of the vehicle. After obtaining the position of the vehicle, the service control center 100 determines the road section condition of the position of the vehicle according to an electronic map stored in a GIS (Geographic information system). In this case, the network architecture involved may be as shown in fig. 2, with the addition of a location service system 300 and a GIS 400 connected to the service control center 100 on the basis of fig. 1. In the system shown in fig. 2, the location service system 300 may not be included, and the service control center 100 detects the location of the vehicle by instructing the in-vehicle terminal 200. The system shown in fig. 2 may not include the GIS 400, and an electronic map may be preset in the service control center 100, or the current traffic condition of the road section where the vehicle is located may be obtained through the traffic condition information provided by other systems.
One structure of the in-vehicle terminal 200 in the above network architecture may be as shown in fig. 3, including: a receiving unit 301, a control unit 302, a state acquisition unit 303, a brake control unit 304, and a vehicle speed control unit 305. Wherein,
the receiving unit 301 is configured to receive an instruction for controlling a vehicle sent by a network side (e.g., the service control center 100 in fig. 1 and fig. 2), and forward the instruction to the control unit 302. The indication received by the unit to control the vehicle may be a status acquisition indication, an indication to control the vehicle to brake immediately, or an indication to control the vehicle to reduce the speed.
A control unit 302, configured to instruct a state obtaining unit 303 to obtain a current state of the vehicle when the instruction forwarded by the receiving unit 301 is a state obtaining instruction; when the indication forwarded by the receiving unit 301 is an indication for controlling the vehicle to brake immediately, the indication for controlling the vehicle to brake immediately is sent when the network side determines that the vehicle meets the preset immediate braking condition according to the state of the vehicle, and the indication for controlling the vehicle to brake immediately is sent by the indication controlling unit 304; when the instruction forwarded by the receiving unit 301 is an instruction for controlling the vehicle to reduce the speed, the instruction for controlling the vehicle to reduce the speed is sent when the network side determines that the vehicle does not meet the preset immediate braking condition according to the state of the vehicle, and the vehicle speed control unit 305 controls the vehicle to reduce the speed.
A state acquiring unit 303, configured to acquire a current state of the vehicle according to an instruction of the control unit 302, and send the acquired state information to the network side.
And the brake control unit 304 is used for controlling the vehicle to brake immediately according to the instruction of the control unit 302.
And a vehicle speed control unit 305 for controlling the vehicle to reduce the vehicle speed according to the instruction of the control unit 302.
The state obtaining instruction received by the receiving unit 301 may include obtaining a vehicle speed of the vehicle, and accordingly, the state obtaining unit 302 is further configured to obtain the vehicle speed of the vehicle. The status acquisition instruction received by the receiving unit 301 may further include a location where the vehicle is located, and correspondingly, the status acquisition unit 302 is further configured to acquire the location of the vehicle where the vehicle is located, where the location is used by the network side to determine a condition of a road segment where the vehicle is located.
The brake control unit 304 may immediately brake the vehicle by controlling a brake system of the vehicle. Further, in order to more effectively brake the vehicle immediately, the brake control unit 304 may control the brake system of the vehicle to brake the vehicle immediately after or at the same time as the fuel supply system of the vehicle is turned off.
The vehicle speed control unit 305 may control the oil supply system of the vehicle to be closed so as to reduce the vehicle speed; or, according to the control parameter carried in the indication for controlling the vehicle to reduce the speed sent by the network side or the control parameter preset in the unit, the oil supply system of the vehicle is controlled to be periodically closed and opened. Wherein the control parameters may include: controlling the closing period of the oil supply system and the closing time of the oil supply system each time.
The vehicle-mounted terminal 200 in this embodiment may further include a monitoring unit and a monitoring unit (not shown in the figure), where the monitoring unit is configured to collect video information inside the vehicle according to an image collection instruction of the service control center 100, and send the collected video information to the service control center 100 on the network side. The monitoring unit is configured to collect sound information inside the vehicle according to a sound collection instruction of the service control center 100, and send the collected sound information to the service control center 100 on the network side. The service control center 100 analyzes the condition of the interior of the vehicle based on the received sound and video information, and provides reference information for more effectively controlling the vehicle. The in-vehicle terminal 200 may have only a monitoring function or a monitoring function, as necessary.
The vehicle-mounted terminal 200 in this embodiment may further include a power supply unit (not shown), and the unit is provided with a main power supply, and the main power supply may be connected to a battery of the vehicle and is responsible for daily power supply. The unit can be further provided with a standby power supply which is generally a rechargeable power supply, and when the main power supply is normal, the standby power supply can be charged in real time, so that when the main power supply is abnormal to the vehicle storage battery, the operation of the vehicle-mounted terminal is guaranteed.
With reference to the network structures shown in fig. 1 to 2 and the vehicle-mounted terminal structure shown in fig. 3, a service flow for implementing remote control of vehicle braking in the embodiment of the present invention is shown in fig. 4, and includes the following steps:
In this step, the vehicle speed may be included in the state of the vehicle obtained by the service control center 100, and the process of obtaining the vehicle speed of the vehicle may be: sending a vehicle speed acquisition instruction to a receiving unit 301 in a vehicle-mounted terminal 200 on a vehicle, forwarding the vehicle speed acquisition instruction to a control unit 302 by the receiving unit 301, and after receiving the instruction by the control unit 302, indicating a state acquisition unit 303 to determine the vehicle speed of the vehicle; or a position acquisition instruction is sent to the receiving unit 301 in the vehicle-mounted terminal 200 on the vehicle, the receiving unit 301 forwards the position acquisition instruction to the control unit 302, and after the control unit 302 receives the instruction, the instruction state acquisition unit 303 positions the position of the vehicle before and after the set time interval, or the position of the vehicle before and after the set time interval can be directly positioned through the position service system 300. After the positions of the vehicle before and after the set time interval are located, the vehicle speed of the vehicle is further calculated according to the distance between the located positions and the set time interval.
Further, the state of the vehicle obtained by the service control center 100 may further include a road section condition where the vehicle is located, and the process of determining the road section condition where the vehicle is located may be: the position acquisition instruction is sent to the receiving unit 301 in the vehicle-mounted terminal 200, the receiving unit 301 forwards the position acquisition instruction to the control unit 302, and after the control unit 302 receives the instruction, the state acquisition unit 303 is instructed to locate the position of the vehicle, or the position of the vehicle can be directly located through the position service system 300. After the vehicle position is located, the road section condition of the located position is further determined. Generally, the position located by the position server system 300 is not as accurate as the position located by the in-vehicle terminal 200, so the state acquisition unit 303 in the in-vehicle terminal 200 may be instructed to locate the position of the vehicle first, and when the position located by the in-vehicle terminal 200 is not received for a set period of time, the position service system 300 may be instructed to locate the position of the vehicle and determine the link status of the located position.
In this step, when the state acquired by the service control center 100 includes the vehicle speed of the vehicle, the preset immediate braking condition may include: the speed of the vehicle is less than a set threshold value, and the threshold value is a numerical value greater than 0; when the state acquired by the service control center 100 includes the speed of the vehicle and the condition of the section of the road where the vehicle is located, the preset immediate braking condition may include: the speed of the vehicle is less than a set threshold value and the condition of the road section where the vehicle is located allows the vehicle to brake.
In step 403, the service control center 100 instructs the in-vehicle terminal 200 mounted on the vehicle to control the vehicle to brake immediately.
In this step, the service control center 100 transmits an instruction to control the immediate braking of the vehicle to the receiving unit 301 in the in-vehicle terminal 200.
And step 404, the vehicle-mounted terminal 200 controls the vehicle to brake immediately according to the instruction for controlling the vehicle to brake immediately, which is sent by the service control center 100.
In this step, after receiving the instruction for controlling the vehicle to brake immediately sent by the service server 100, the receiving unit 301 forwards the instruction to the control unit 302, and the control unit performs unified scheduling. After receiving the instruction, the control unit 302 instructs the brake control unit 304 to brake the vehicle immediately. The brake control unit 304 may immediately brake the vehicle by controlling a brake system of the vehicle in which it is located. In order to more effectively control the vehicle to brake immediately, the brake control unit 304 may also control the brake system of the vehicle to brake the vehicle immediately after the oil supply system controlling the vehicle is turned off.
In step 405, the service control center 100 instructs the in-vehicle terminal 200 mounted on the vehicle to control the vehicle to reduce the vehicle speed.
In this step, the service control center 100 sends an instruction for controlling the vehicle to reduce the vehicle speed to the receiving unit 301 in the vehicle-mounted terminal 200, where the instruction for controlling the vehicle to reduce the vehicle speed may carry a control parameter for controlling the vehicle to reduce the vehicle speed by the user.
And step 406, the vehicle-mounted terminal 200 controls the vehicle to reduce the speed until the vehicle stops according to the instruction for controlling the vehicle to reduce the speed, which is sent by the service control center 100.
In step 406, after receiving the instruction for controlling the vehicle to reduce the speed sent by the service server 100, the receiving unit 301 transfers the instruction to the control unit 302, and the control unit performs unified scheduling. After receiving the instruction, the control unit 302 instructs the vehicle speed control unit 305 to control the vehicle to reduce the vehicle speed. The vehicle speed control unit 305 may reduce the vehicle speed by controlling the oil supply system of the vehicle to be turned off. In order to further improve the safety, the vehicle speed control unit 305 may also control the oil supply system of the vehicle to be periodically turned off and on according to a control parameter carried in an instruction sent by the service control center 100 on the network side to control the vehicle to reduce the vehicle speed or a preset control parameter, so that the corresponding acceleration is reduced when the vehicle speed is reduced.
The control parameters related to steps 405 and 406 may include a period for controlling the closing of the oil supply system and a time period for controlling the closing of the oil supply system each time. The corresponding relationship between different vehicle speeds and different control parameters may be preset in the service control center 100 or the vehicle speed control unit 305, so that different control parameters may be selected according to different vehicle speeds of the vehicle to more effectively control the vehicle to reduce the vehicle speed until the vehicle stops. The vehicle can also be controlled to reduce the speed according to preset default control parameters. Generally, the control parameters preset in the vehicle speed control unit 305 may be selected, which may reduce the amount of information transmitted by the network side, thereby reducing the load on the network side and improving the transmission efficiency and response speed.
In the embodiment of the present invention, the correspondence between the license plate number of the vehicle and the ID of the in-vehicle terminal 200 on the vehicle may be configured in advance in the service control center 100 on the network side or in another network entity accessible to the service control center 100. In step 401, when the user finds that the vehicle is driven illegally or operated illegally, the user may initiate a braking control request for the vehicle to the service control center 100 in various manners such as Web, Wap, short message, voice, or when some traffic control departments find that the vehicle is driven illegally, the user may initiate a braking control request for the vehicle to the service control center 100 on the network side, and the service control center 100 may search for the ID (for example, a communication number) of the corresponding vehicle-mounted terminal 200 according to the license plate number carried in the request, and determine the state of the vehicle where the vehicle-mounted terminal is located by communicating with the vehicle-mounted terminal corresponding to the ID. The driving prohibition condition preset for the vehicle in the network side may be set according to a user requirement or a related department, for example, a driving prohibition area outside a prescribed setting range is defined as the driving prohibition area of the vehicle, or a prescribed setting time period is defined as the driving prohibition time of the vehicle, and when the user starts monitoring the vehicle (the monitoring of the vehicle is started may also be a default setting of the system), if it is detected that the vehicle is driving in the driving prohibition area or driving in the driving prohibition time, it is determined that the driving prohibition condition for the vehicle is satisfied. Further, in step 401, the service control center 100 may also perform authentication on the user initiating the braking control request, for example, to verify whether the user initiating the braking control request is the owner of the vehicle, or to verify whether the user initiating the braking control request has the right to brake the vehicle.
In the above step 401, the state acquiring unit 303 in the in-vehicle terminal 200 may determine the vehicle speed of the vehicle in general by:
the first method is as follows: a transmission connection with a vehicle determines a speed of the vehicle. Specifically, the state obtaining unit 303 may include a vehicle speed sensor, the vehicle speed sensor may be a hall vehicle speed sensor, when the vehicle is running, a plurality of magnet pieces on the hall vehicle speed sensor and an output shaft of a transmission case of the vehicle rotate synchronously, a vehicle speed pulse signal reflecting the running vehicle speed of the vehicle is input into a vehicle speed pulse and pulse counting processing circuit through a hall probe, and a vehicle speed pulse number for mileage counting of a single chip microcomputer is generated after the vehicle speed pulse and pulse counting processing circuit is shaped and counted, so that the running vehicle speed of the vehicle is determined.
The second method comprises the following steps: and calculating the speed of the vehicle according to the distance between the positions of the vehicle before and after the set time interval. Specifically, the positions of the vehicle before and after the set time interval can be located, and the vehicle speed of the vehicle can be determined according to the ratio of the distance between the two located positions to the set time interval.
And thirdly, connecting the speed meter with the vehicle to determine the speed of the vehicle.
It should be noted that the method for determining the vehicle speed by the state acquiring unit 303 in the present embodiment is not limited to the above-mentioned several manners, and only a few common manners are listed here.
In step 401, the process of determining the status of the road segment where the vehicle is located by the status obtaining unit 303 in the in-vehicle terminal 200 may be:
the in-vehicle terminal 200 mounted on the vehicle is instructed to locate the position of the vehicle. Specifically, a position acquisition instruction is sent to the receiving unit 301 in the vehicle-mounted terminal 200, the receiving unit 301 forwards the position acquisition instruction to the control unit 302, the control unit 302 performs unified scheduling according to the instruction, the control unit 302 receives the instruction and then instructs the state acquisition unit 303 to position the position of the vehicle, the state acquisition unit 302 can determine the current position of the vehicle through positioning technologies such as GPS or AGPS, and the obtained positioning result is generally a longitude and latitude coordinate. After locating the vehicle position, the state acquisition unit 302 transmits the located position information to the service control center 100 on the network side.
If the service control center 100 in the network side does not receive the location information returned by the state acquisition unit 303 in the vehicle-mounted terminal 200 for a set duration, it is determined that the vehicle-mounted terminal 200 fails to locate the vehicle location, at this time, the terminal identifier corresponding to the vehicle-mounted terminal 200 is obtained and sent to the location service system 300, and after receiving the terminal identifier information, the location service system 300 locates the location of the vehicle-mounted terminal 200 corresponding to the terminal identifier. The process of the service control center 100 obtaining the terminal identifier corresponding to the vehicle-mounted terminal 200 specifically includes: the license plate number of the vehicle is obtained, and the terminal identifier corresponding to the vehicle-mounted terminal 200 is obtained according to the pre-stored correspondence between the license plate number and the terminal identifier, where the terminal identifier may be a Subscriber Identity Module (SIM) card number embedded in the vehicle-mounted terminal 200.
