When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
FIG. 1 is a flow diagram illustrating a refueling prompting method according to an exemplary embodiment, which may include the following steps, as shown in FIG. 1.
In step 101, the current remaining fuel quantity of the vehicle is acquired.
In step 102, it is detected whether the in-vehicle system navigates to a specified destination.
The vehicle-mounted system can be a system which is arranged in a vehicle and used for acquiring use parameters of various devices in the vehicle, navigating, prompting according to related information and interacting information with other mobile terminals.
In step 103, when it is detected that the in-vehicle system does not navigate to the specified destination, it is detected whether the vehicle can reach a buffer location after passing through a refueling station closest to the vehicle on the route while traveling with the remaining amount of fuel, and the distance between the buffer location and the refueling station is less than a predetermined distance threshold.
In step 104, when the vehicle travels with the remaining amount of fuel, the vehicle is prompted to travel to the nearest refueling station for refueling when the vehicle fails to reach the buffer point after traveling to the nearest refueling station on the route.
In summary, the refueling prompting method provided in the embodiment of the disclosure judges in advance whether the currently driving route can reach the nearest refueling station by using the remaining fuel according to the remaining fuel amount of the vehicle and the position of the refueling station; the problem that the number of charging piles is small, and the vehicle is easily broken down is solved; the effect of effectively avoiding the anchoring phenomenon of the vehicle caused by insufficient fuel is achieved.
In one implementation scenario, if the on-board system in the vehicle is not used to navigate to the specified destination, it is also necessary to monitor the refueling stations around the vehicle in real time in order to ensure that the vehicle is refueling in time. See in particular the description of fig. 2A.
FIG. 2A is a flow chart illustrating a refueling prompting method according to another exemplary embodiment, which may include the following steps, as shown in FIG. 2A.
In step 201, the current remaining fuel amount of the vehicle is acquired.
After a user starts the vehicle, the vehicle-mounted system in the vehicle automatically acquires the current residual fuel quantity of the vehicle.
Generally, when a vehicle is enabled by fuel, the remaining amount of fuel is the remaining amount of fuel; when the vehicle is enabled by electric energy, the remaining amount of fuel is the remaining amount of electricity.
In step 202, it is detected whether the in-vehicle system navigates to a specified destination.
The vehicle-mounted system can be a system which is arranged in a vehicle and used for acquiring use parameters of various devices in the vehicle, navigating, prompting according to related information and interacting information with other mobile terminals.
In step 203, when it is detected that the in-vehicle system does not navigate to the specified destination, it is detected whether the vehicle can reach a buffer location after passing through a refueling station closest to the vehicle on the route while traveling with the remaining amount of fuel, and the distance between the buffer location and the refueling station is smaller than a predetermined distance threshold.
When the fact that the vehicle-mounted system does not navigate to the specified destination is detected, in order to guarantee that the vehicle can be supplied with fuel in time in the driving process, whether the vehicle can reach the buffer location after passing through a fuel supply station closest to the vehicle on the route when the vehicle drives by using the residual fuel quantity can be detected in real time.
The buffer location is a location where the vehicle needs to travel a distance after traveling to the nearest refueling station, and this is mainly a location provided to avoid that the vehicle cannot reach the nearest refueling station due to an accident (for example, traffic jam, road blockage, a wrong travel route, or a route traveled to the nearest refueling station is not the shortest route) during traveling, so as to ensure that the vehicle can reach the refueling station nearest to the vehicle even after the accident occurs.
In other words, the vehicle inevitably encounters some unexpected situations, such as traffic jam, road blockage, etc., during the driving process, and when these situations occur, if the vehicle wants to drive to the nearest refueling station for refueling, some fuel may be consumed in addition to the fuel that must be consumed by driving to the nearest refueling station. In order to ensure that the remaining amount of fuel is sufficient to ensure that the vehicle can reach the nearest refueling station, when the remaining amount of fuel is used to calculate the distance to travel to the nearest refueling station, it is necessary to increase the distance to travel beyond the refueling station in addition to calculating the distance to travel to the nearest refueling station.
The distance from the refueling station to the buffer location may be set according to actual road conditions or experience, for example, may be preset to 1km or 2km, and the values of the distance from the refueling station to the buffer location are not limited in the embodiments of the present disclosure.
In one possible implementation, please refer to fig. 2B, which is a flowchart illustrating a method for detecting whether a vehicle can reach a buffer location after passing a refueling station closest to the vehicle when traveling with a remaining amount of fuel according to an exemplary embodiment, and as shown in fig. 2B, the refueling prompting method may include the following steps.
In step 203a, the amount of fuel lost per unit distance traveled by the vehicle is obtained.
After a user starts the vehicle, the vehicle-mounted system can obtain the fuel quantity consumed in a unit journey through methods such as automatic calculation or direct acquisition.
In step 203b, the remaining fuel amount is divided by the amount of fuel consumed per trip to obtain the distance that can be traveled by the remaining fuel amount.
Let a be the remaining fuel amount, b be the fuel amount consumed by the unit journey traveled, and c be the distance a/b the remaining fuel amount can travel.
In step 203c, it is checked whether the distance that can be traveled by the remaining amount of fuel is greater than the distance from the current location of the vehicle to the buffer location after passing through the refueling station closest to the vehicle.
Setting the distance that the residual fuel can travel as x, the distance from the current location of the vehicle to the buffer location as y, and if x is larger than y, the vehicle-mounted system does not prompt that fuel is needed to be replenished; if x < y, the on-board system prompts for refueling.
In step 204, when the vehicle travels with the remaining amount of fuel, the vehicle is prompted to travel to the nearest refueling station for refueling when the vehicle fails to reach the buffer point after traveling to the nearest refueling station on the route.
When the vehicle travels by using the residual fuel quantity, the vehicle cannot reach the buffer point after passing through the fuel refilling station closest to the vehicle on the route, the fact that the residual fuel quantity of the vehicle cannot guarantee that the vehicle reaches the closest fuel refilling station if the vehicle travels randomly is generally indicated, so that the vehicle is prompted to travel to the closest fuel refilling station for refilling, and the situation that the residual fuel quantity is insufficient to reach the closest fuel refilling station due to traveling to other places is avoided.
Here, when prompting to drive the vehicle to the nearest refueling station for refueling, the vehicle may be prompted by a bell, a voice prompt, or the like, may be prompted by a vibration of a steering wheel, or may be prompted by a text prompt on a display screen corresponding to the in-vehicle system, or the like.
In step 205, the redirected navigation is performed based on the route from the current location of the vehicle to the nearest refueling station.
In order to ensure that the user can drive the vehicle to correctly drive to the nearest fuel station, the vehicle-mounted system can take the nearest fuel station as a destination to perform redirection navigation.
In order to facilitate a user to view the position relationship between the current vehicle and the accessory refueling station, a first buffer point which is on each path where the vehicle is located and is a preset distance away from the vehicle can be determined, wherein the preset path is a distance which can be traveled by the residual fuel of the vehicle, a second buffer point which is farthest away from the vehicle is determined from the first buffer points, a circle defined by taking the current location of the vehicle as a center of the circle and the distance from the determined second buffer point to the vehicle as a radius is used, and an area corresponding to the circle is highlighted. The user then checks to see if a refueling station exists within the circle, or if the only one refueling station within the circle is located within the circle and near the edge of the circle, and if so, indicates that the vehicle needs to be refueled to that refueling station. Referring to fig. 2C, the distance that the vehicle can travel according to the remaining amount of fuel can pass through a buffer location a behind a refueling station a, at this time, taking the current location of the vehicle as a center of a circle and the distance from the buffer location a to the current location of the vehicle as a radius, determining a circle S, where the circle S defines a range where the refueling station a exists, selecting the refueling station a closest to the current location of the vehicle, setting the distance that the remaining amount of fuel can travel as x, setting the path from the current location of the vehicle to the refueling station a as L1, setting the path from the refueling station a to the buffer location a as L2, and if x < L1+ L2 is detected, it indicates that the vehicle can not refuel to the closest refueling station a any more, an anchor drop phenomenon is likely to occur, so that the vehicle is prompted to refuel to the closest remaining fuel at this time, and the current location of the vehicle is taken as a starting point, the redirect navigation is performed with the fueling station a as a destination.
In summary, the refueling prompting method provided in the embodiment of the disclosure pre-determines whether the currently driving route can reach the nearest refueling station by using the remaining fuel according to the remaining fuel amount of the vehicle and the position of the refueling station; the problem that the number of charging piles is small, and the vehicle is easily broken down is solved; the effect of effectively avoiding the anchoring phenomenon of the vehicle caused by insufficient fuel is achieved.
In addition, when the vehicle-mounted system does not navigate to a specified destination and detects that the vehicle cannot reach the buffer point after passing through the fuel refilling station closest to the vehicle on the route when the vehicle runs by using the residual fuel amount, the redirection navigation can be carried out according to the route from the current position of the vehicle to the closest fuel refilling station, so that the condition that the vehicle is anchored because of running to other positions can be avoided.
In another practical application scenario, while the vehicle is driving, an on-board system inside the vehicle may be used to navigate to a specified destination. In order to ensure that the vehicle can safely travel to the specified destination, it is required to calculate whether the remaining fuel amount can reach the specified destination, that is, after step 202, steps 206 to 210 in fig. 3A may be further included, which may be specifically referred to in the description of fig. 3A.
FIG. 3A is a flow chart illustrating a refueling prompting method according to another exemplary embodiment, which may include the following steps, as shown in FIG. 3A.
In step 206, when it is detected that the in-vehicle system navigates to a specified destination, it is detected whether the vehicle can reach a refueling station closest to the destination after passing the destination while traveling with the remaining amount of fuel.
In one possible implementation, if the amount of fuel remaining after the vehicle has traveled to the designated destination is insufficient to travel to the refueling station closest to the destination, the next trip of the vehicle may be affected, resulting in the vehicle being stranded. In order to avoid such a situation, it is necessary to detect whether the vehicle can reach the refueling station closest to the destination after passing through the destination when the vehicle travels with the remaining amount of fuel, when the vehicle-mounted system navigates to the specified destination before the vehicle departs.
In one possible implementation, please refer to fig. 3B, which is a flowchart illustrating a method for detecting whether a vehicle can reach a refueling station closest to a destination after passing the destination while traveling with a remaining amount of fuel according to another exemplary embodiment, and as shown in fig. 3B, the refueling prompting method may include the following steps.
In step 206a, the amount of fuel lost per unit distance traveled by the vehicle is obtained.
In step 206b, the remaining fuel amount is divided by the amount of fuel consumed per trip to obtain the distance traveled by the remaining fuel amount.
Since steps 206a to 206b are identical to steps 203a to 203b, they will not be described in detail.
In step 206c, it is checked whether the distance that can be traveled by the remaining amount of fuel is greater than the distance from the current location of the vehicle to the refueling station closest to the destination after passing through the destination.
Setting the distance that the residual fuel quantity can travel as x, and the distance from the current location of the vehicle to the fuel refilling station closest to the destination as y, wherein if x is greater than y, the vehicle-mounted system does not prompt that fuel refilling is needed; if x < y, the on-board system prompts for refueling.
In step 207, when the vehicle passes through the destination and fails to reach the refueling station closest to the destination while traveling with the remaining amount of fuel, it is prompted to travel to the refueling station for refueling.
When the vehicle passes through the destination and fails to reach the refueling station closest to the destination when running by using the residual fuel amount, the vehicle is generally indicated that the residual fuel amount of the vehicle is not enough to run to the refueling station closest to the destination through the destination, and then the vehicle is prompted to run to the refueling station for refueling.
Here, when prompting to drive the vehicle to the nearest refueling station for refueling, the vehicle may be prompted by a bell, a voice prompt, or the like, may be prompted by a steering wheel vibration, or may be prompted by a text prompt or the like on a display screen corresponding to the in-vehicle system.
Since the remaining amount of fuel of the vehicle is not sufficient to travel through the destination to the refueling station closest to the destination, in order to avoid the vehicle being stranded, the vehicle may be redirected first to the refueling station. Please refer to the description of steps 208 to 210 below.
In step 208, at least one refueling station located on a route from the current location of the vehicle to the destination direction is determined.
If the vehicle is detected to pass through the destination when running by using the residual fuel quantity and then cannot reach the fuel station closest to the destination, the vehicle-mounted system can also acquire the position of the fuel station on the route of the vehicle to the destination direction in the navigation map. Alternatively, the on-board system may screen out refueling stations on a shortest path for the vehicle to reach the destination where it is currently located.
In step 209, one of the determined refueling stations that the vehicle can reach with the remaining amount of fuel is selected.
After the vehicle-mounted system searches out the refueling stations through the navigation map, screening is carried out in search results according to the residual fuel utilization amount of the vehicle, one or more refueling stations which can be reached by the vehicle through the residual fuel utilization amount are selected, the refueling stations are arranged according to the distance of the journey, the user selects the position of going to the refueling stations by himself, and when the vehicle can reach only one refueling station, the vehicle-mounted system can appoint the refueling station by default.
Optionally, after determining a plurality of refueling stations, the vehicle-mounted system may prompt the user to select one of the refueling stations.
In step 210, redirected navigation is performed based on a route from the current location of the vehicle to the selected fueling station.
When the vehicle-mounted system selects a refueling station or a user selects one refueling station after being prompted by the vehicle-mounted system, the vehicle-mounted system carries out redirection navigation according to a route from the current location of the vehicle to the selected refueling station, the redirection navigation plans various possible routes from the current location of the vehicle to the selected refueling station, including a route with the shortest required route or a better route (such as a high-speed route or a non-high-speed route, and the like, and the type of the route which can be navigated by the user can be selected), and displays on a navigation map, and the user selects whether to navigate according to the route of the redirection navigation provided by the vehicle-mounted system.
In a possible implementation manner, in order to ensure that the vehicle can correctly travel to the destination after refueling, the vehicle-mounted system may use the refueling station as the current location to perform redirection navigation on the destination, that is, the vehicle-mounted system performs redirection navigation by using the selected refueling station as the starting point and the destination as the end point.
Referring to fig. 3C, different routes may be provided from the current location to the destination, and two routes are listed in fig. 3C, the in-vehicle system first detects whether the vehicle can reach the refueling station E closest to the destination after passing through the destination when traveling with the remaining amount of fuel, if the vehicle cannot reach the refueling station E, detects whether the remaining amount of fuel can reach the refueling station E near the shortest route 2 from the location to the destination, and if the vehicle can reach the destination, the vehicle is navigated to the refueling station E first, and then the destination is used as the starting point to perform redirection navigation; if the vehicle can not reach the destination, whether the residual fuel quantity can reach a refueling station A near a route 1 of the location to the destination is detected (the route of the route 1 is larger than the route 2, but the route of the location to the refueling station A is smaller than the route to the refueling station E), if the vehicle can reach the destination, the vehicle is navigated to the refueling station A, and then the redirection navigation is carried out by taking the refueling station A as a starting point and taking the destination as a terminal.
In summary, the refueling prompting method provided in the embodiment of the disclosure pre-determines whether the currently driving route can reach the nearest refueling station by using the remaining fuel according to the remaining fuel amount of the vehicle and the position of the refueling station; the problem that the number of charging piles is small, and the vehicle is easily broken down is solved; the effect of effectively avoiding the anchoring phenomenon of the vehicle caused by insufficient fuel is achieved.
In addition, when the vehicle-mounted system navigates to a specified destination and detects that the vehicle cannot reach the fuel refilling station closest to the destination after passing through the destination when traveling with the surplus fuel, the vehicle is redirected according to the route from the current location of the vehicle to the selected fuel refilling station, so that the situation that the vehicle is stranded due to the fact that the surplus fuel cannot travel to the fuel refilling station closest to the destination after reaching the destination can be avoided.
