Fig. 2 is another schematic flow chart of a vehicle position information determination method according to an embodiment of the present application. Fig. 2 depicts the solution of the present application in more detail with respect to fig. 1.
Referring to fig. 2, the method includes:
step S201, vehicle data of at least one historical time point from the data sending terminal is obtained.
The data transmission terminal may include a cloud server and/or an Advanced Driving Assistance System (ADAS). That is to say, the data sending terminal may be a cloud server (e.g., a cloud-controlled base platform), the data sending terminal may also be a vehicle ADAS, and the data sending terminal may further include the cloud server and the vehicle ADAS. Further, the data transmission terminal may also be an ADAS of another vehicle.
It should be noted that the cloud server may issue the vehicle data to each terminal (for example, a vehicle-mounted terminal of the vehicle) according to a set period (threshold). For example, the cloud server issues vehicle data to each terminal every 200 ms. The vehicle data monitored by the vehicle ADAS may also be transmitted to the vehicle-mounted terminal of the vehicle according to a set period.
The vehicle data may include one or more of vehicle position information, vehicle speed information, and time information (e.g., satellite time), among others. Further, the vehicle data may also include model type (e.g., sedan, SUV, van, truck, etc.), vehicle size, relative distance of the host vehicle from other vehicles, and so forth. Further, the vehicle data may include vehicle position information, vehicle speed information, time information, and vehicle type of a plurality of different vehicles (e.g., own vehicle, own nearby vehicle).
In this step, vehicle data at one historical time point from the data transmission terminal may be acquired. Further, the vehicle data of a latest historical time point from the data transmission terminal, that is, the vehicle data of a historical time point closest to the current time point from the data transmission terminal may be acquired. In other embodiments, vehicle data from a plurality of continuous or intermittent historical time points of the data transmission terminal may also be acquired. Further, the vehicle data at a plurality of recent consecutive historical time points from the data transmission terminal. It can be understood that, in the case where the cloud server issues the vehicle data to each terminal every 200ms, the time interval of the plurality of consecutive history time points is 200 ms.
Step S202, according to the vehicle data of at least one historical time point, the position information of the vehicle at the current time point is determined.
The vehicle is a related vehicle corresponding to the vehicle data. The vehicle may be a self vehicle, one or more vehicles around the self vehicle, or one or more vehicles including the self vehicle and the periphery of the self vehicle. That is, in this step, the vehicle data of the own vehicle may be acquired, the vehicle data of one or more vehicles around the own vehicle may be acquired, and the vehicle data of the own vehicle and the one or more vehicles around the own vehicle may be acquired.
In this step, in one embodiment, the position information of the vehicle at the current time point may be determined according to the vehicle data of the latest one of the at least one historical time point. That is, the position information of the vehicle at the current time point may be determined according to the vehicle data at the historical time point corresponding to the data transmission cycle in which the data transmission terminal is closest to the current time point. In this embodiment, the vehicle-mounted terminal may receive vehicle data of a latest historical time point sent by the data sending terminal, calculate a time difference with respect to a current time point according to vehicle position information, vehicle speed (vector, including velocity and direction) information, and time information included in the vehicle data, and predict a travel distance of the vehicle by multiplying the speed of the vehicle at the latest historical time point by the time difference in combination with a position where the vehicle at the latest historical time point is located, thereby determining the position information of the vehicle at the current time point; further, the position information can be converted into longitude and latitude values for representation.
In another embodiment, the position information of the vehicle at the current time point may be determined according to the vehicle data of a plurality of recent historical time points among the at least one historical time point. Preferably, the position information of the vehicle at the current time point may be determined according to vehicle data of a plurality of recent consecutive history time points in the at least one history time point. The number of the plurality of historical time points may be a preset number, and preferably, the vehicle data of the 3 historical time point data transmitting terminals in the continuous cycle closest to the current time point is acquired. In this embodiment, the vehicle-mounted terminal may receive vehicle data of a plurality of historical time points in a latest continuous cycle sent by the data sending terminal, calculate a time difference between a latest historical time point and a current time point according to vehicle position information, vehicle speed (vector, including speed and direction) information and time information included in the vehicle data, calculate an average speed of the vehicle of the plurality of historical time points in combination with a position of the vehicle of the latest historical time point, and predict a travel distance of the vehicle by multiplying the average speed of the vehicle by the time difference, thereby determining the position information of the vehicle of the current time point; further, the position information can be converted into longitude and latitude values for representation.
In this step, the vehicles may include the own vehicle and one or more vehicles around the own vehicle, that is, the position information of the own vehicle and the one or more vehicles around the own vehicle at the current time point may be determined.
Further, the vehicle may include a nearby vehicle within a first set range. The first setting range may be peripheral vehicles within a preset distance radius range centered on the own vehicle, for example, the first setting range may be peripheral vehicles within a radius of 500m centered on the own vehicle.
In another embodiment, the vehicle may include a nearby vehicle within a second set range; the second setting range is smaller than or equal to the maximum monitoring range of the ADAS of the vehicle, and the second setting range is smaller than the first setting range. The second setting range may be located within a maximum monitoring range of the own vehicle ADAS, so as to ensure that the vehicle-mounted terminal can acquire vehicle data of a vehicle at a historical time point from the own vehicle ADAS.
And S203, rendering and displaying the position information of the vehicle at the current time point.
In the step, the position information of the vehicle at the current time point can be rendered and displayed on a display screen of the vehicle-mounted terminal, so that the high-precision map drawing with accuracy is realized. Further, the information displayed by rendering may further include a type of vehicle, a size of vehicle, and the like of the relevant vehicle.
In the embodiment of the application, the position information of the surrounding vehicle within the first set range at the current time point can be rendered and displayed. The first setting range may be a range within a radius of 500m with the vehicle as a center, so that the driver can know the position information of the surrounding vehicle within the radius of 500m through the vehicle-mounted terminal display screen. Further, the vehicle data issued by one of the data sending terminals may be acquired according to a preset rule, or the vehicle data issued by different data sending terminals may be acquired at different time periods according to a preset rule.
In one embodiment, when the vehicle data of at least one historical time point corresponding to the first set period comes from the cloud server, the position information of the surrounding vehicle at the current time point within the first set range may be rendered and displayed. The first set period may be the last several periods. For example, the cloud server issues data every 200ms, and the first set period may be 400ms, 600ms, 800ms, and so on. That is to say, under the condition that the position information of the vehicle at the current time point is obtained according to the vehicle data issued by the cloud server in the first set period, the position information of the surrounding vehicle at the current time point in the first set range is rendered and displayed. Correspondingly, it can be understood that, from the perspective of the current time, if the vehicle data received by the vehicle-mounted terminal at a plurality of corresponding time points in the future set period is from the cloud server, the position information of the surrounding vehicle at the next time point in the future set period within the first set range can be rendered and displayed.
In another embodiment, when the vehicle data of the corresponding at least one historical time point in the second set period is from the own vehicle ADAS, the position information of the surrounding vehicle with the current time point within the second set range may be rendered and displayed. That is to say, under the condition that the position information of the vehicle at the current time point is obtained according to the vehicle data issued by the ADAS of the vehicle in the second set period, the position information of the surrounding vehicle at the current time point within the second set range is rendered and displayed. The second setting range may be smaller than or equal to the maximum monitoring range of the vehicle ADAS, and the second setting range may be smaller than the first setting range. Correspondingly, it can be understood that, from the perspective of the current time, if the vehicle data received by the vehicle-mounted terminal at a plurality of corresponding time points in the future set period is from the vehicle ADAS, the position information of the surrounding vehicle at the next time point in the future set period within the second set range can be rendered and displayed.
The cloud server has the advantages that the coverage range of the cloud server is large, so that the first setting range with the large range can be set, more position information of the surrounding vehicles can be displayed, and a driver can know more detailed movement conditions of the surrounding vehicles. The coverage range which can be monitored by the vehicle ADAS is smaller, so that a second set range with a smaller range can be set, and the position information of the surrounding vehicles can be displayed as much as possible under the condition that the position information of the related vehicles is correct.
It can be seen from this embodiment that, with the method provided in the embodiment of the present application, after the position information of the vehicle at the current time point is determined, the position information of the vehicle at the current time point can be rendered and displayed, so that high-precision map drawing work with high accuracy is realized.
