参照图1，提出本发明一实施例的辅助汽车定位的方法，应用于服务器或车载***，为方便理解，本发明以应用于服务器作为例子进行阐述，该方法包括步骤：Referring to FIG. 1, a method for assisting vehicle positioning according to an embodiment of the present invention is applied to a server or an in-vehicle system. For ease of understanding, the present invention is applied to a server as an example, and the method includes the steps of:

本实施例中，汽车具有车载***，车载***上安装有SIM卡，与服务器通过网络连接。服务器实时监听汽车的位置信息，服务器获取汽车位置信息失败，主要是两种原因，一是汽车的GPS信号丢失，在室内(地下停车场)或隧道等无法定位的地方；另一个主要原因是汽车的网络信号不好，汽车无法与服务器网络连接，从而服务器无法获取汽车的位置信息。通常地，服务器会实时获取并保存的车载***的第一时间对应的车位置信息，在监听到获取汽车位置信息失败后，调取服务器获取汽车位置信息失败前一刻的的汽车位置信息，即汽车的第一汽车位置信息，同时也获取在该第一汽车位置信息的第一时间信息。同时服务器也获取汽车的预驾驶速度。预驾驶速度可以是服务器预存的速度，也可以是由其它信息分析出的速度。再计算出当前时间 第一时间信息之间的第一时间间隔，模拟计算出汽车的信号丢失后行驶的路程，然后根据行驶路程，分析出汽车的当前位置。服务器获取当前时间信息，计算出与第一时间信息之间的第一时间间隔，例如第一时间信息是18:00，当前时间信息是18:20，计算出的第一时间间隔是20分钟，获取的预驾驶速度是60公里/小时，则模拟行驶路程是20分钟乘以60公里/小时，得出20公里，再将20公里投射在地图上，分析汽车的当前位置。In this embodiment, the automobile has an in-vehicle system, and the SIM card is installed on the in-vehicle system, and is connected to the server through a network. The server monitors the location information of the car in real time, and the server fails to obtain the location information of the car. There are two main reasons. First, the GPS signal of the car is lost, and it cannot be located indoors (underground parking lot) or tunnel; another main reason is the car. The network signal is not good, the car can't connect to the server network, so the server can't get the location information of the car. Generally, the server obtains and saves the vehicle position information corresponding to the first time of the in-vehicle system in real time, and after detecting the failure to obtain the position information of the vehicle, retrieves the position information of the vehicle immediately before the failure of the server to obtain the position information of the vehicle, that is, the automobile. The first car position information also acquires the first time information of the first car position information. At the same time, the server also gets the pre-driving speed of the car. The pre-driving speed can be the speed pre-stored by the server or the speed analyzed by other information. Then calculate the first time interval between the first time information of the current time, simulate the distance traveled after the signal of the car is lost, and then analyze the current position of the car according to the travel distance. The server obtains the current time information, and calculates a first time interval between the first time information, for example, the first time information is 18:00, the current time information is 18:20, and the calculated first time interval is 20 minutes. The pre-driving speed obtained is 60 km/h, and the simulated driving distance is 20 minutes multiplied by 60 km/h to obtain 20 km, and then 20 km is projected on the map to analyze the current position of the car.

On the navigation line, let the user intuitively understand the distance when the car signal is lost and the current position. Wherein, when marking, the current position is marked as a color different from the normal mark, so as to indicate the current position calculated according to the simulated travel route analysis after the signal is lost.

本实施例中，获取汽车的第一汽车位置信息时，获取到的GPS都是带有方向的，根据方向信息，根据已驾驶路线以及方向信息，生成 预驾驶路线，所遵循的原则是尽量远离汽车的启动的位置。例如，汽车发动时的位置是在深南大道上沿深南大道向东行驶2公里后，然后右拐进入南海大道向南行驶，3分钟后，在南海大道上服务器获取汽车位置信息失败，则服务器判定方向信息是向南，根据已驾驶路线，重新规则的预驾驶路线是沿着南海大道向南行驶，在下一个路口处直行继续向南行驶或者向左拐向东行行驶，而不是向右拐向西行驶。In this embodiment, when the first car position information of the automobile is acquired, the acquired GPS is all with a direction, and according to the direction information, the pre-driving route is generated according to the driven route and the direction information, and the principle to follow is to be as far as possible The location of the car's start-up. For example, when the car is started, it is 2 km east of Shennan Avenue on Shennan Avenue, then turn right into Nanhai Avenue and drive south. After 3 minutes, the server fails to obtain the car location information on Nanhai Avenue. The server determines that the direction information is southward. According to the driving route, the re-ruling pre-driving route is to drive south along Nanhai Avenue. At the next intersection, go straight to the south or turn left to the east instead of to the right. Turn to the west.

本实施例中，预驾驶速度，是根据驾驶人从发车时开车的速度计算出来的。计算启动的启动时间信息，具体的，是指汽车点火发动时间，也可以是汽车挂上前进档(手动档的一档或自动档的D档)的时间，计算汽车启动时间与第一时间信息之间的第二时间间隔，就是指汽车与网络连接情况下行驶的时间，再根据汽车的里程表计算出第二时间间隔内的已行驶路程，用已行驶路程除以第二时间间隔，则可以得出平均驾驶速度，该平均驾驶速度即预驾驶速度。In the present embodiment, the pre-driving speed is calculated based on the speed at which the driver drives from the time of departure. Calculate the startup start time information, specifically, the ignition time of the car, or the time when the car is hung up in the forward gear (the first gear of the manual gear or the D gear of the automatic gear), and calculate the car start time and the first time information. The second time interval between the two refers to the time of travel between the car and the network, and then calculates the traveled distance in the second time interval according to the odometer of the car, and divides the traveled distance by the second time interval. The average driving speed can be derived, which is the pre-driving speed.
进一步地，所述获取预驾驶速度的步骤包括：Further, the step of acquiring the pre-driving speed includes:
S84、获取所述预驾驶路线上的路况信息，所述路况信息包括道路属性以及拥堵情况；S84. Acquire road condition information on the pre-driving route, where the road condition information includes road attributes and congestion conditions;
S85、根据所述路况信息生成对应的预驾驶速度。S85. Generate a corresponding pre-driving speed according to the road condition information.
本实施例中，服务器在计算得到预驾驶路线后，获取该预驾驶路线上的路况，其中路况信息包括道路属性以及拥堵情况，道路属性就是指道路的等级、类别、车道数量等道路的信息。不同的属性的道路限制的最高行驶速度是不一样的。拥堵情况是服务器获取其他服务器分析得出的该道路上平均车辆的行驶速度，根据二者的结合，得到预驾驶速度。其中，其他服务器分析得出道路上的平均车辆的行驶速度是根据时间的变化而变化的。例如，其他服务器分析出南海大道上的 平均行驶速度是：In this embodiment, after calculating the pre-driving route, the server acquires the road condition on the pre-driving route, wherein the road condition information includes the road attribute and the congestion situation, and the road attribute refers to the information of the road, such as the grade, the category, the number of lanes, and the like. The maximum speed of road restrictions for different attributes is different. The congestion situation is that the server obtains the average speed of the vehicle on the road obtained by other servers, and according to the combination of the two, the pre-driving speed is obtained. Among them, other servers analyzed that the average speed of the vehicle on the road changes according to the change of time. For example, other servers analyzed the average travel speed on Nanhai Avenue:
Figure PCTCN2018072004-appb-000001
Figure PCTCN2018072004-appb-000001
Figure PCTCN2018072004-appb-000002
Figure PCTCN2018072004-appb-000002
其中，上述括号内的表示分析出的速度的时间，在此预驾驶速度是变化的基础上，计算模拟行驶路程时，可以是叠加计算，例如，服务器先在第一时间信息获得此时汽车所在的道路平均速度是30km/h，则3分钟内的模拟行驶路程是1.5公里，对应的将汽车的第一汽车位置信息沿着预行驶路线移动1.5公里，得到汽车当前位置。并再获得汽车当前位置所在的道路的平均速度是60km/h，第一时间间隔达到6分钟时，计算模拟行驶路程是在原来的模拟行驶路程上叠加，即3min*60km/h＝3km，即汽车再更新当前位置时，距离刚才的汽车当前位置是3公里路程，距离第一汽车位置信息是4.5公里路程。在具体的计算过程中，为了更准确的模拟计算汽车的当前位置，服务器每隔3秒钟获取其他服务器分析得出道路上的平均车辆的行驶速度。Wherein, the time in the parenthesis indicating the analyzed speed is based on the change of the pre-driving speed, and when calculating the simulated driving distance, the calculation may be superimposed. For example, the server first obtains the information at the first time information. The average speed of the road is 30km/h, and the simulated driving distance within 3 minutes is 1.5 kilometers. Correspondingly, the first car position information of the car is moved along the pre-driving route for 1.5 kilometers to obtain the current position of the car. And the average speed of the road where the current position of the car is located is 60km/h. When the first time interval reaches 6 minutes, the calculated simulated driving distance is superimposed on the original simulated driving distance, that is, 3min*60km/h=3km, ie When the car re-updates its current location, the current location of the car is 3 kilometers away, and the location information of the first car is 4.5 kilometers. In the specific calculation process, in order to calculate the current position of the car more accurately, the server obtains the average speed of the average vehicle on the road by analyzing the other servers every 3 seconds.
综上所述，本发明的辅助汽车定位的方法，当汽车的GPS信号丢失，或者车载***的网络差无法将GPS信号上传至服务器，服务器根据信号丢失前的驾驶路线以及驾驶速度，计算出汽车的位置，帮助汽车进行定位，用户访问服务器可以了解汽车的大概位置。根据驾驶人设置的导航目的地，可以准确的计算出网络丢失后的预驾驶路线。服务器访问第三方服务器获得预驾驶路况的平均速度，更加准确的模拟计算出汽车的实时位置。In summary, the method for assisting vehicle positioning according to the present invention calculates a car when the GPS signal of the car is lost or the network of the in-vehicle system cannot upload the GPS signal to the server, and the server calculates the driving route and the driving speed before the signal is lost. The location helps the car to locate, and the user accesses the server to know the approximate location of the car. According to the navigation destination set by the driver, the pre-driving route after the network is lost can be accurately calculated. The server accesses the third-party server to obtain the average speed of the pre-driving road conditions, and more accurately simulates the real-time position of the car.
参照图2，本发明还提出一种辅助汽车定位的装置，辅助汽车定位的装置为服务器或车载***，为方便理解，本发明以应用于服务器作为例子进行阐述，本发明的服务器包括：Referring to FIG. 2, the present invention also provides an apparatus for assisting vehicle positioning.

本实施例中，获取汽车的第一汽车位置信息时，获取方向模块62获取到的GPS都是带有方向的，第二预驾驶路线模块63根据方向信息，根据已驾驶路线以及方向信息，生成预驾驶路线，所遵循的原则是尽量远离汽车的启动的位置。例如，汽车发动时的位置是在深南大道上沿深南大道向东行驶2公里后，然后右拐进入南海大道向南行驶，3分钟后，在南海大道上服务器获取汽车位置信息失败，则获取方向模块62判定方向信息是向南，第二预驾驶路线模块63根据已驾驶路线，重新规则的预驾驶路线是沿着南海大道向南行驶，在下一个路口处直行继续向南行驶或者向左拐向东行行驶，而不是向右拐向西行驶。In this embodiment, when acquiring the first vehicle position information of the automobile, the GPS acquired by the acquisition direction module 62 is all oriented, and the second pre-driving route module 63 generates the driving route and the direction information according to the direction information. The pre-driving route follows the principle of staying away from the starting position of the car. For example, when the car is started, it is 2 km east of Shennan Avenue on Shennan Avenue, then turn right into Nanhai Avenue and drive south. After 3 minutes, the server fails to obtain the car location information on Nanhai Avenue. The obtaining direction module 62 determines that the direction information is southward, and the second pre-driving route module 63 follows the driven route. The re-ruling pre-driving route is to go south along Nanhai Avenue, and go straight to the south or left at the next intersection. Turn to the east instead of turning right and west.
参照图9，进一步地，所述速度模块8包括：Referring to FIG. 9, further, the speed module 8 includes:
第二时间间隔单元81，用于获取启动时间信息至第一时间信息之间的第二时间间隔；a second time interval unit 81, configured to acquire a second time interval between the startup time information and the first time information;
已行驶路程单元82，用于获取所述第二时间间隔内的已行驶路 程；The traveled route unit 82 is configured to acquire the traveled route in the second time interval;
计算速度单元83，用于根据所述已行驶路程以及所述第二时间间隔，计算出所述汽车在第二时间间隔内的行驶速度，并将所述行驶速度作为所述预驾驶速度。The calculating speed unit 83 is configured to calculate a traveling speed of the automobile in a second time interval according to the traveled distance and the second time interval, and use the traveling speed as the pre-driving speed.
本实施例中，预驾驶速度，是根据驾驶人从发车时开车的速度计算出来的。第二时间间隔单元81计算启动的启动时间信息，具体的，是指汽车点火发动时间，也可以是汽车挂上前进档(手动档的一档或自动档的D档)的时间，第二时间间隔单元81计算汽车启动时间与第一时间信息之间的第二时间间隔，就是指汽车与网络连接情况下行驶的时间，已行驶路程单元82再根据汽车的里程表计算出第二时间间隔内的已行驶路程，计算速度单元83用已行驶路程除以第二时间间隔，则可以得出平均驾驶速度，该平均驾驶速度即预驾驶速度。In the present embodiment, the pre-driving speed is calculated based on the speed at which the driver drives from the time of departure. The second time interval unit 81 calculates the startup start time information, specifically, the time when the car is ignited, or the time when the car is hung up in the forward gear (the first gear of the manual gear or the D gear of the automatic gear), the second time The interval unit 81 calculates a second time interval between the vehicle start time and the first time information, which is the time when the car is connected to the network, and the traveled route unit 82 calculates the second time interval according to the odometer of the car. The traveled distance, the calculated speed unit 83 divides the traveled distance by the second time interval, and the average driving speed, that is, the pre-driving speed, can be derived.
参照图10，进一步地，所述速度模块8包括：Referring to FIG. 10, further, the speed module 8 includes:
路况信息单元84，用于获取所述预驾驶路线上的路况信息，所述路况信息包括道路属性以及拥堵情况；The road condition information unit 84 is configured to acquire road condition information on the pre-driving route, where the road condition information includes road attributes and congestion conditions;
生成速度单元85，用于根据所述路况信息生成对应的预驾驶速度。The generating speed unit 85 is configured to generate a corresponding pre-driving speed according to the road condition information.
本实施例中，在计算得到预驾驶路线后，路况信息单元84获取该预驾驶路线上的路况，其中路况信息包括道路属性以及拥堵情况，道路属性就是指道路的等级、类别、车道数量等道路的信息。不同的属性的道路限制的最高行驶速度是不一样的。拥堵情况是服务器获取其他服务器分析得出的该道路上平均车辆的行驶速度，生成速度单元85根据二者的结合，得到预驾驶速度。其中，其他服务器分析得出道路上的平均车辆的行驶速度是根据时间的变化而变化的。例如，其他服务器分析出南海大道上的平均行驶速度是：In this embodiment, after calculating the pre-driving route, the road condition information unit 84 acquires the road condition on the pre-driving route, wherein the road condition information includes the road attribute and the congestion situation, and the road attribute refers to the road grade, the category, the number of lanes, and the like. Information. The maximum speed of road restrictions for different attributes is different. The congestion situation is that the server acquires the average vehicle travel speed on the road obtained by other servers, and the generation speed unit 85 obtains the pre-drive speed according to the combination of the two. Among them, other servers analyzed that the average speed of the vehicle on the road changes according to the change of time. For example, other servers analyzed the average speed of travel on Nanhai Avenue:
Figure PCTCN2018072004-appb-000003
Figure PCTCN2018072004-appb-000003
Figure PCTCN2018072004-appb-000004
Figure PCTCN2018072004-appb-000004
其中，上述括号内的表示分析出的速度的时间，在此预驾驶速度 是变化的基础上，计算模拟行驶路程时，可以是叠加计算，例如，服务器先在第一时间信息获得此时汽车所在的道路平均速度是30km/h，则3分钟内的模拟行驶路程是1.5公里，对应的将汽车的第一汽车位置信息沿着预行驶路线移动1.5公里，得到汽车当前位置。并再获得汽车当前位置所在的道路的平均速度是60km/h，第一时间间隔达到6分钟时，计算模拟行驶路程是在原来的模拟行驶路程上叠加，即3min*60km/h＝3km，即汽车再更新当前位置时，距离刚才的汽车当前位置是3公里路程，距离第一汽车位置信息是4.5公里路程。在具体的计算过程中，为了更准确的模拟计算汽车的当前位置，服务器每隔3秒钟获取其他服务器分析得出道路上的平均车辆的行驶速度。Wherein, the time in the parenthesis indicating the analyzed speed is based on the change of the pre-driving speed, and when calculating the simulated driving distance, the calculation may be superimposed. For example, the server first obtains the information at the first time information. The average speed of the road is 30km/h, and the simulated driving distance within 3 minutes is 1.5 kilometers. Correspondingly, the first car position information of the car is moved along the pre-driving route for 1.5 kilometers to obtain the current position of the car. And the average speed of the road where the current position of the car is located is 60km/h. When the first time interval reaches 6 minutes, the calculated simulated driving distance is superimposed on the original simulated driving distance, that is, 3min*60km/h=3km, ie When the car re-updates its current location, the current location of the car is 3 kilometers away, and the location information of the first car is 4.5 kilometers. In the specific calculation process, in order to calculate the current position of the car more accurately, the server obtains the average speed of the average vehicle on the road by analyzing the other servers every 3 seconds.
