Description
Technical Field
The invention relates to the field of intelligent buses, in particular to a method and a device for determining a driving route and computer equipment.
Background
Currently, most buses are equipped with a GPS (global Positioning System), and during a driving process, the buses can obtain a current GPS position of a vehicle in real time based on the GPS Positioning System, and if a distance between the current GPS position of the vehicle and a GPS position of a certain stop is smaller than a specified threshold, it can be determined that the vehicle enters the stop.
The bus needs to turn around or turn around when running on the routes, if stops are also arranged near the turning positions of the routes, the bus may repeatedly enter the same stop, such as the bus in fig. 1 enters the stop a, then the bus is driven out and turned around from the stop a, and then the bus enters the stop a again.
For special stops arranged near turning positions, the related art generally adjusts the GPS positions of the special stops to positions far away from the center of a road, taking a stop a on a U-shaped route as an example, the original GPS position of the stop a is shown in fig. 1A, and the adjusted GPS position of the stop a is shown in fig. 1E, and it can be seen from the figure that the adjusted stop a is deviated to one side of the road, so that a bus enters the stop a, and then exits from the stop a and turns around, and since the turned-around vehicle can travel on the other side of the road, the distance between the vehicle travel position and the GPS position of the stop a can be larger than a specified threshold, the bus cannot determine that the bus repeatedly enters the stop a, and therefore the problem that the actual travel route is changed cannot be determined, and the problem of misdetermination is avoided.

Fig. 3A is a flowchart of a method for determining a driving route according to an embodiment of the present invention. Referring to fig. 3A, the method includes:
301. and when the current station of the vehicle is detected to be the same as the previous station, determining a target driving position of the vehicle on the currently set driving route according to the currently set driving route, wherein the target driving position is determined based on the current station of the vehicle.
The vehicle can be a bus or other vehicles with fixed driving routes, such as a school bus and a subway. For convenience of description, the embodiment of the present invention is described by taking an example that the driving route determining method is applied to a bus, the bus is equipped with a GPS positioning system, the bus can obtain the current GPS position of the bus in real time based on the GPS positioning system, and the positions mentioned in the following description can be GPS positions.
The currently set driving route can be an uplink route or a downlink route set for the bus by a bus company, wherein the uplink route is a route from a starting station to a terminal station of the bus, and comprises relevant information of each station between the starting station and the terminal station, such as a GPS position, a station name, a station peripheral sight spot and the like; the downlink route is a route for a bus to travel from a terminal station to an origin station and comprises relevant information of all stations between the terminal station and the origin station. The uplink and the downlink may include different stations, for example, each station in the uplink may be a station a, a station B, a station C, a station D, a station E, and a station F, and each station in the downlink may be a station F, a station D, a station G, a station C, and a station a.
The currently set driving route may be a turning route, the turning route refers to a route in which a bus needs to turn around or turn to drive when the bus drives from a stop to a next stop in the driving route, such as a U-shaped route, a V-shaped route, an L-shaped route, an N-shaped route, and the like, referring to fig. 1A, the U-shaped route refers to a route in which the bus drives along a road to a position point (e.g., a position near the stop a) and then turns around and then drives along the road, the driving direction after turning around is opposite to the driving direction before turning around, referring to fig. 1B, the V-shaped route refers to a route in which the bus drives along a road to a position point and then turns around at an angle to another road, that is, the driving direction after turning around forms an angle with the driving direction before turning around, referring to fig. 1C, L-shaped route is one of the V-shaped route, the driving direction after turning around forms an angle with the driving direction before turning around a 90 degrees with referring to fig. 1D, the N-shaped route refers to an example that the bus turns around on the U-shaped route after turning around, and a route is a route that the current stop a, and a route is a route, and a route that is a route that is not a route that is a route, and a route that is an example, and a route that is a route.
The currently set driving route can be used for reminding passengers to get off in a bus stop reporting mode when the bus enters the bus stop. Specifically, in the driving process of the bus, the current position of the bus can be compared with the position of each stop in the driving route currently set by the bus, and if the distance between the current position of the bus and the position of one stop in the currently set driving route is smaller than a specified threshold value, the bus can be determined to enter the station, and the name of the current stop is broadcasted in the bus. Of course, the currently set driving route may also have other uses, such as for a bus company to monitor the actual position of the bus in real time or to set scheduling information for the bus, where the scheduling information is used to indicate when the bus is to be dispatched from a starting station or an ending station.
In the embodiment of the invention, when the distance between the current position of the bus and the position of the last stop is detected to be smaller than the specified threshold value, the current stop of the bus and the last stop of the bus can be determined to be the same, namely, the bus repeatedly enters the same stop, as shown in fig. 1A, the bus is firstly driven out from the stop A, and the bus is detected to enter the stop A again after turning around. When the bus detects the repeated arrival condition, the bus needs to judge whether the actual running route of the bus is changed, namely, whether the repeated arrival condition is that the bus normally turns to run or the bus returns from a midway station (the bus does not arrive at a terminal station and directly returns from the midway station of the currently set running route), and whether the currently set running route of the bus is changed or not is determined according to the judgment result. The specific determination process may include this step 301 and subsequent steps 302 to 304.
In one possible implementation manner, the determining the target driving position of the vehicle on the currently set driving route according to the currently set driving route in step 301 may include steps a to c:
a. and determining the next station of the current station of the vehicle according to the currently set driving route.
In the step a, the bus may determine a next stop of the current stop according to the currently set driving route and the current stop, and specifically, the bus may determine a first stop sequentially following the current stop as the next stop of the current stop according to a sequence of each stop in the currently set driving route. For example, the order of the various sites is: the starting station- > site A- > site B- > site C- > … … - > terminal station, and if site A is the current site, site B is the next site of site A.
b. And if no turning point exists between the current station and the next station of the vehicle, determining the position of the next station as the target driving position.
The step B is directed to the currently set driving route being the U-shaped route shown in fig. 1A, the V-shaped route shown in fig. 1B, the L-shaped route shown in fig. 1C, and other routes where no turning point exists between the current stop and the next stop, the embodiment of the present invention may determine whether the actual driving route of the vehicle has changed by determining whether the vehicle is driving to the next stop of the current stop, referring to fig. 4, the bus detects that the vehicle repeatedly enters a stop, such as a station a (the previous stop), then exits from the station a, turns around and then enters again to the station a (the current stop), since there is no turning point between the station a and the station B (the next stop of the current stop) in the driving direction after the vehicle exits from the station a again, and the station B is in front of the driving direction after the vehicle exits from the station a again, the bus may directly determine the position of the station B as the target driving position of the vehicle, and determine whether the position of the vehicle and the station B are approaching through the subsequent step 302, thereby determining whether the vehicle is driving to the station B.
c. If a turning point exists between the current station and the next station of the vehicle, determining the position of the turning point between the current station and the next station of the vehicle as the target driving position.
The step c is to aim at the currently set driving route to be an N-type route and other routes with turning points between the current stop point and the next stop point. As shown in fig. 4, since turning points (e.g., turning point 1 and turning point 2) exist between a current stop (e.g., stop a) and a next stop (e.g., stop B) in a traveling direction after the vehicle is driven out from the stop a again, the traveling position of the vehicle becomes farther from the next stop during traveling to the next stop after the bus is driven out from the current stop, and therefore the bus cannot determine whether the vehicle is traveling to the next stop of the current stop by merely determining whether the traveling position of the vehicle is approaching the position of the next stop. Considering that the position of the turning point is ahead of the driving direction of the vehicle after exiting from the current stop, the bus may determine the position of the turning point as the target driving position of the vehicle, and determine whether the driving position of the vehicle and the position of the turning point are approaching through the subsequent step 302, thereby determining whether the vehicle is driving toward the turning point, and further determining whether the vehicle is driving toward the next stop of the current stop.
The position of the turning point can be input into the driving route in advance by a technician, and the input mode can be manual input or automatic input. The manual entry means that the positions of the turning points are set between two stops when a bus company plans a bus driving route, so that the currently set driving route comprises the positions of the stops and the positions of the turning points. The automatic recording is that the bus determines the turning of the bus through the gravity sensing equipment on the bus under the mode of automatically recording the stop, and automatically sets the position of the turning point between two stops of the current driving route. The gravity sensor can measure acceleration caused by gravity, and can calculate the inclination angle of the bus relative to the horizontal plane, the bus can determine whether the bus turns according to the inclination angle output by the gravity sensor, if the inclination angle is larger than a specified angle, the bus can determine that the bus turns, and otherwise, the bus can determine that the bus does not turn. If there are multiple turning points between station A and station B, the current travel route between station A and station B may be set to: the station A- > turning point 1- > turning point 2- > … … - > turning point N- > station B, namely, the vehicle passes through the station A, the turning point 1, the turning points 2 and … …, the turning point N and the station B in sequence in the process of driving from the station A to the station B. By recording the positions of the turning points in advance, the bus can remind a user of turning the bus and asking the user to stand stably in a broadcasting mode when the bus reaches one turning point during driving, so that the riding safety of passengers is guaranteed.
It should be noted that, since there may be a plurality of turning points between the current station and the next station, the bus may determine the target driving position a plurality of times, that is, perform step 301 a plurality of times. After step 301 is executed, the following step 302 is executed, if the vehicle is traveling to the target traveling position as a result of the determination in step 302, step 303 is executed and the vehicle continues to travel until the target traveling position is reached, and if the target traveling position reached by the vehicle is not the next station of the current station, the next target traveling position is determined when the vehicle exits the target traveling position. Referring to fig. 5, the bus detects that the vehicle repeatedly enters the station a, such as the vehicle enters the station a, then exits from the station a, and enters the station a again after turning around, at this time, the bus may determine the target driving position of the vehicle according to the position of the turning point in the currently set driving route and the current position of the vehicle, such as determining the first turning point between the current station and the next station as the target driving position, and performing the subsequent step 302, if the determination result of the step 302 is that the vehicle is not driving to the first turning point, directly performing the step 304, and if the determination result of the step 302 is that the vehicle is driving to the first turning point, performing the step 303, and when the vehicle exits the first turning point, determining the position of the second turning point as the next target driving position, and so on until the last turning point is determined as the target driving position, then, after the vehicle exits the last turning point, the bus can continue to determine the next stop as the target driving position until the vehicle reaches stop B.
302. And determining whether the vehicle is running towards the target running position according to the real-time position of the vehicle during the running process of the vehicle.
In the embodiment of the invention, when the bus is driven out of the current stop, the bus can continue to drive forwards, and in the process of continuously driving, the bus can determine whether the bus drives to the target driving position currently. In one possible implementation, the determination process may be: and if the distance between the real-time position of the vehicle and the target position is gradually reduced along with the change of time, determining that the vehicle is driving towards the target driving position. Specifically, the bus may obtain the distance between the vehicle position and the target driving position in real time according to the vehicle position obtained in real time, and if the distance between the vehicle position obtained by the bus and the target driving position is smaller and smaller along with the change of time, the bus may determine that the bus is driving to the target driving position.
303. And if the vehicle runs to the target running position, determining that the actual running route of the vehicle is not changed, and keeping the currently set running route.
In the embodiment of the present invention, for the U-shaped route, the V-shaped route or the L-shaped route in step B of step 301, the target driving position is the position of the station next to the current station as shown in fig. 4, if the vehicle drives to the next station (station B) after driving from the current station (station a), the bus can determine that the vehicle normally drives according to the currently set driving route, and the actual driving route of the vehicle is not changed.
For the N-type route in step c of step 301, the target driving position is the position of a turning point between the current station and the next station. As shown in fig. 5, for the turning point 1, if the bus is traveling toward the turning point 1 after exiting from the current station (station a), the bus may determine that its actual traveling route has not changed; for the turning point 2, if the bus is driving to the turning point 2 after the bus is driven out from the turning point 1, the bus may determine that its actual driving route is not changed. Of course, the last target driving position determined under the route may be the next station (station B) to the current station. As shown in fig. 5, after the bus is driving out of the last turning point (turning point 2) and the station B is determined as the target driving position, if it is determined that the bus is driving toward the station B, the bus may determine that its actual driving route is not changed.
When the bus is detected to repeatedly enter the station, the bus can determine that the bus normally runs according to the currently set running route by determining that the bus runs to the next station of the current station or the turning point between the current station and the next station, and the actual running route is not changed, so that the situation that the bus mistakenly judges that the actual running route is changed when the bus repeatedly enters the station is avoided.
In order to achieve the above determination of the target travel position, the travel route determination means may store the GPS positions of the respective travel positions on the travel route, for example, for a stop or a turning point, in the form as shown in fig. 3B, and store the GPS positions of the respective GPS travel positions on one travel route as one piece of data.
304. And if the vehicle does not travel to the target travel position, determining that the actual travel route of the vehicle is changed, and changing the currently set travel route of the vehicle.
For the U-shaped route, the V-shaped route, or the L-shaped route in step B of step 301, if the bus is not traveling to the next stop next to the current stop after exiting from the current stop, as shown in fig. 4, if the bus is not traveling to stop B, the bus may determine that it is not traveling normally according to the currently set traveling route, but returns from a midway stop of the currently set route, and the actual traveling route of the bus is changed.
For the N-type route in step c of step 301, as shown in fig. 5, for a turning point, if the bus has not traveled to the turning point 1 after exiting from the current stop a, or the bus has not traveled to the next turning point 2 after exiting from the turning point 1, the bus may determine that its actual travel route has changed.
It should be noted that step 304 is only an optional step in the embodiment of the present invention, and actually, the problem of erroneous determination when the bus repeatedly enters the station can be solved through steps 301 to 303. The optional step 304 can avoid the loss of the function of correctly judging that the actual driving route of the bus is changed, so that when the bus actually returns from the midway station of the currently set driving route, the bus can normally realize the judging function.
In the embodiment of the invention, when the actual driving route of the bus is determined to be changed, because the actual driving route of the bus is different from the currently set driving route, the actual driving route is a downlink route, but the currently set driving route is an uplink route, and the stop of the uplink route is possibly different from the stop of the downlink route, when the real-time position of the bus in the actual driving process is compared with the stop position in the currently set driving route, the stop with the distance from the real-time position being less than the specified threshold value can not be found, that is, the stop can not be normally reported according to the currently set driving route, so that the current setting needs to be changed. In one possible implementation, the altering process may include: if the currently set running route is the uplink route of the bus, switching the currently set running route from the uplink route to the downlink route; and if the currently set running route is the downlink route of the bus, switching the currently set running route from the downlink route to the uplink route.
In another embodiment of the invention, after the bus changes the current set driving route, the changed driving route can be reported to the server, and after the server receives the changed driving route of the bus, the server can set the scheduling information for the bus again and send the latest scheduling information to the bus, so that the scheduling of the bus is more in line with the actual situation. Under normal conditions, namely if the actual running route of the bus does not change, the bus automatically switches the uplink route and the downlink route of the bus only after reaching the terminal station, and acquires the scheduling information sent by the server.
It should be noted that, in the embodiment of the present invention, a repeated arrival situation is taken as an example for description, and in fact, if such a repeated arrival situation occurs many times during the driving process of the bus, the bus may execute the driving route determining method for the repeated arrival situation each time, so as to determine whether the actual driving route of the bus is changed.
According to the method provided by the embodiment of the invention, when the vehicle is detected to repeatedly enter the station, the vehicle is determined to normally run according to the currently set running route by determining that the vehicle approaches to the next running position of the current station, so that the misjudgment problem that the actual running route of the vehicle is changed once the repeated entering of the station occurs is avoided, the whole determination process can be automatically carried out, manual participation is not needed, and the operation is simple.
In addition, the next driving position of the current station can be the position of the next station of the current station or the position of a turning point between the current station and the next station, and the position of the next station or the turning point is determined as the target driving position of the vehicle, so that whether the actual driving route of the vehicle changes or not can be determined by judging whether the vehicle is close to or far away from the next station or the turning point, and the determination method of the driving route is set for various different routes, so that the judgment error caused by different actual road conditions on the routes is avoided.
