The cost required by the travel by bus is one of the important bases for selecting the travel mode by the user. At the present stage, various methods for estimating the trip fare of the manned vehicle exist, and the estimation methods can accurately calculate the required trip fare of the manned vehicle. In the invention, the manned vehicle is an operating vehicle controlled by a driver to drive, such as a common taxi or a network taxi; the unmanned vehicle is an operation vehicle which is not controlled by a driver in the vehicle, has automatic driving capability and uses new energy. However, since the unmanned vehicle has a special attribute different from that of the manned vehicle, the method for estimating the trip cost of the manned vehicle cannot be applied to the unmanned vehicle. Therefore, the invention provides a method, a device, equipment and a computer storage medium for estimating the fare of the unmanned vehicle, which are used for estimating the fare of the unmanned vehicle and improving the accuracy of the fare of the unmanned vehicle.
Fig. 1 is a flowchart of a method according to an embodiment of the present invention, and as shown in fig. 1, the method may mainly include the following steps:
in 101, a user taking car request sent by a client is obtained, wherein the user taking car request comprises a departure address and a destination address.
In this step, the user request includes the departure address and the destination address, or further includes the riding time. Optionally, in a specific implementation process of this embodiment, the starting address of the user may be an address where the client is located, or an address input by the user. When the user inputs the departure place address or the destination address by himself, the user can input the departure place address or the destination address in a manual editing mode or in a clicking or selecting mode on the map.
Optionally, in a specific implementation process of this embodiment, the client may be an application located in the local terminal, or may also be a functional unit such as a plug-in or Software Development Kit (SDK) located in the local terminal application, or may also be another device located in the network side server, which is not particularly limited in this embodiment.
At 102, the fare estimation is carried out according to the distance between the departure place address and the nearest charging pile or the distance between the destination address and the nearest charging pile and the passenger riding distance from the departure place address to the destination address.
In this step, before the fare estimation is performed according to the riding request of the user, the riding distance of the passenger from the departure address to the destination address, the distance from the departure address to the nearest charging pile and the distance from the destination address to the nearest charging pile need to be obtained first. And planning a path according to the departure address and the destination address in the user riding request, and acquiring the passenger riding distance from the departure address to the destination address. The passenger riding distance is obtained according to the starting point and the ending point, which belongs to the prior art and is not described in detail herein.
When the distance from the departure location to the nearest charging pile and the distance from the destination location to the nearest charging pile are obtained, the position of the nearest charging pile to the departure location and the position of the nearest charging pile to the destination location need to be obtained respectively. In the step, the position of the charging pile closest to the departure address and the position of the charging pile closest to the destination address are respectively obtained through a charging pile index equation. Wherein, fill electric pile index equation and obtain for the position distribution data of filling electric pile according to the city in advance, fill electric pile index equation and be:
p(i)＝f1(xi,yi)
in the formula: p (i) represents the ith charging post, which contains the coordinates of the location of the ith charging post; (x)i,yi) Representing the coordinates of a location.
And because the index equation of the charging pile is obtained according to the position distribution data of the charging pile in the city, if the position distribution data of the charging pile in different cities are different, the obtained index equation of the charging pile is different. Optionally, in a specific implementation process of this embodiment, for a departure address and a destination address in a ride request of a user, which need to be located in the same city, an index of a charging pile is performed by using a charging pile index equation corresponding to the city. And determining which cities the departure address and the destination address are respectively located in according to the departure address and the destination address, and then using a charging pile index equation corresponding to the corresponding cities to index the charging piles. The following description will be given taking as an example that the user riding request is located in the same city.
Therefore, the position of the charging pile closest to the departure place address and the position of the charging pile closest to the destination address are respectively obtained according to the departure place address and the destination address in the riding request of the user through the charging pile index equation. After the positions of the charging piles closest to the departure address and the destination address are respectively obtained, the distance calculation equation is used, the distance between the departure address and the charging pile closest to the departure address is obtained according to the departure address and the position of the charging pile closest to the departure address, and the distance between the destination address and the charging pile closest to the destination address is obtained according to the destination address and the position of the charging pile closest to the destination address.
The calculation equation of the distance between the departure place address and the nearest charging pile is as follows:
dsp＝f2[(xs,ys),p(n)]
in the formula: dspRepresenting the distance between the departure address and the nearest charging pile, (x)s,ys) And p (n) represents the position coordinate of the starting place address, and the position coordinate of the charging pile closest to the starting place address.
The calculation equation of the distance between the destination address and the nearest charging pile is as follows:
dep＝f2[(xe,ye),p(m)]
in the formula: depRepresents the distance between the destination address and the nearest charging pile (x)e,ye) And p (m) represents the location coordinates of the nearest charging post to the destination address.
After the distance from the departure address to the nearest charging pile, the passenger riding distance from the departure address to the destination address and the distance from the destination address to the nearest charging pile are obtained, the fare of the riding request of the user can be estimated by using an estimation equation. In this step, the fare estimation equations used are respectively:
Cost＝ω0’*dse+ω3*dep
in the formula: cost is an estimated fare, omega0' is a second unit price, dseFor passenger riding distance, omega3Is a third unit price, depThe distance between the destination address and the nearest charging pile.
Cost＝ω0’*dse+ω4*dsp
In the formula: cost is an estimated fare, omega0' is a second unit price, dseFor passenger riding distance, omega4Is a fourth unit price, dspThe distance between the destination address and the nearest charging pile.
When the fare is estimated according to the riding request of the user, a proper estimation equation is selected to estimate the fare by combining the residual running distance of the vehicle, the riding distance of the passenger and the current electric quantity of the vehicle. Therefore, in this step, the current amount of power of the vehicle and the remaining travel distance of the vehicle need to be acquired.
And the acquired current electric quantity of the vehicle is the current residual electric quantity of the vehicle. And estimating the distance capable of being traveled by the vehicle according to the current electric quantity of the vehicle through a vehicle remaining travel distance estimation equation. The estimation equation of the vehicle remaining travel distance is obtained in advance according to the vehicle electric quantity and the historical data of the vehicle remaining travel distance, and the estimation equation is as follows:
dt＝f3(pt)
in the formula: dtRepresenting the remaining distance of travel of the vehicle at time t, ptRepresenting the remaining capacity of the vehicle at time t.
If the obtained vehicle remaining driving distance is larger than the passenger riding distance and the current electric quantity of the vehicle is larger than 50% of the full electric quantity, the vehicle fee estimation equation is a common charging equation:
Cost＝ω0*dse
in the formula: cost is an estimated fare, omega0Is a first unit price, dseFor passenger riding distance.
If the obtained remaining driving distance of the vehicle is greater than the passenger riding distance, but the current electric quantity of the vehicle is less than 50% of the full electric quantity, the estimated equation of the vehicle fee is as follows:
Cost＝ω0’*dse+ω3*dep
if the obtained remaining driving distance of the vehicle is less than the passenger riding distance, the estimated fare equation is as follows:
Cost＝ω0’*dse+ω4*dsp
wherein the first unit price ω0Conventionally charging prices for the market; second unit price ω0' less than the first unit price is satisfied; third unit price ω3And a fourth unit price ω4The charging pile distribution dynamic assignment method can be a preset value, and can also be a dynamic assignment according to the departure place address and the charging pile distribution near the destination address.
For example, the third unit price ω3Fourth unit price ω4When dynamic assignment is performed according to the distribution of the charging piles near the departure address and the destination address, the assignment formulas can be respectively as follows:
ω3＝(dep/dse)*ω0’
ω4＝(dsp/dse)*ω0’
in the formula: depThe distance of the destination address from the nearest charging pile, dseFor passenger riding distance, dspDistance, omega, of destination address from nearest charging pile0' is the second unit price.
For example, if the market price is 1.2 yuan/km, the first unit price is 1.2 yuan/km. According to a riding request of a user, the obtained riding distance of the passenger is 10 kilometers, the distance between a departure address of the passenger and the nearest charging pile is 2 kilometers, the distance between a destination address of the passenger and the nearest charging pile is 4 kilometers, the residual electric quantity of the vehicle is 70% of the full electric quantity of the vehicle, the residual driving distance of the vehicle is 30 kilometers, and according to a prediction equation, the prediction fare of the riding request of the user is as follows: 12 yuan.
For example, if the market price is 1.2 yuan/km, the first unit price is 1.2 yuan/km, the second unit price is 0.6 yuan/km, and the third unit price is 0.3 yuan/km, which is a preset value. According to a riding request of a user, the obtained riding distance of the passenger is 10 kilometers, the distance between a departure address of the passenger and the nearest charging pile is 2 kilometers, the distance between a destination address of the passenger and the nearest charging pile is 4 kilometers, the residual electric quantity of the vehicle is 30% of the full electric quantity of the vehicle, the residual driving distance of the vehicle is 15 kilometers, and according to a prediction equation, the prediction fare of the riding request of the user is as follows: 7.2 yuan.
For example, if the market price is 1.2 yuan/km, the first unit price is 1.2 yuan/km, the second unit price is 0.6 yuan/km, and the fourth unit price is 0.3 yuan/km, which is a preset value. According to the riding request of the user, the obtained riding distance of the passenger is 10 kilometers, the distance between the departure address of the passenger and the nearest charging pile is 2 kilometers, the distance between the destination address of the passenger and the nearest charging pile is 4 kilometers, and the remaining driving distance of the vehicle is 8 kilometers, according to the formula, the estimated fare of the riding request of the user is as follows: 6.6 yuan.
In the step, when the passenger riding distance is greater than the distance between the departure address and the nearest charging pile and the distance between the destination address and the nearest charging pile, the user riding request is subjected to fare estimation by using different estimation equations through judging the size relation between the residual vehicle travelling distance and the passenger riding distance and the size relation between the current electric quantity of the vehicle and 50% of the full electric quantity of the vehicle, and the estimated fare is obtained. If the obtained passenger riding distance is smaller than the distance between the departure address and the nearest charging pile or the distance between the destination address and the nearest charging pile, or the passenger riding distance is smaller than the distance between the departure address and the nearest charging pile and the distance between the destination address and the nearest charging pile, the fare can not be estimated by using the estimation equation.
In 103, the obtained estimated fare is fed back to the client.
In this step, if the estimated fare is obtained according to the riding request of the user, the obtained estimated fare is fed back to the client, and the client can present the estimated fare to the user in a display or voice mode. If the cost can not be estimated by using the estimation equation according to the riding request of the user, the result that the fare can not be estimated is returned to the client, and the client can feed back the fare which can not be estimated to the user in a display or voice mode and can inform the reason.
The following is a detailed description of the structure of the apparatus according to the embodiment of the present invention. As shown in fig. 2, the apparatus includes: an acquisition unit 21, a prediction unit 22 and a feedback unit 23.
The obtaining unit 21 is configured to obtain a user riding request sent by a client, where the user riding request includes a departure address and a destination address.
The user riding request acquired by the acquiring unit 21 includes a departure address and a destination address, or further includes riding time. Optionally, in a specific implementation process of this embodiment, the starting address of the user may be an address where the client is located, or an address input by the user. When the user inputs the departure place address or the destination address by himself, the user can input the departure place address or the destination address in a manual editing mode or in a clicking or selecting mode on the map.
Optionally, in a specific implementation process of this embodiment, the client may be an application located in the local terminal, or may also be a functional unit such as a plug-in or Software Development Kit (SDK) located in the local terminal application, or may also be another device located in the network side server, which is not particularly limited in this embodiment.
And the estimating unit 22 is used for estimating the fare according to the distance between the departure place address and the nearest charging pile or the distance between the destination address and the nearest charging pile and the passenger riding distance from the departure place address to the destination address.
The estimation unit 22 needs to first acquire a passenger riding distance from a departure location address to a destination address, a distance from the departure location address to the nearest charging pile, and a distance from the destination address to the nearest charging pile before estimating the fare according to a riding request of a user. The estimation unit 21 performs path planning according to a departure address and a destination address in a user riding request, and obtains a passenger riding distance from the departure address to the destination address. The passenger riding distance is obtained according to the starting point and the ending point, which belongs to the prior art and is not described in detail herein.
When obtaining the distance between the departure location address and the nearest charging pile and the distance between the destination address and the nearest charging pile, the estimation unit 22 first needs to obtain the position of the nearest charging pile and the position of the nearest charging pile. The estimation unit 22 obtains the position of the charging pile closest to the departure address and the position of the charging pile closest to the destination address through a charging pile index equation. Wherein, fill electric pile index equation and obtain for the position distribution data of filling electric pile according to the city in advance, fill electric pile index equation and be:
p(i)＝f1(xi,yi)
in the formula: p (i) represents the ith charging pile, which comprises the position coordinate of the ith charging pile; (x)i,yi) Representing a location coordinate.
And because the index equation of the charging pile is obtained according to the position distribution data of the charging pile in the city, if the position distribution data of the charging pile in different cities are different, the obtained index equation of the charging pile is different. Optionally, in a specific implementation process of this embodiment, for a departure address and a destination address in a ride request of a user, which need to be located in the same city, an index of a charging pile is performed by using a charging pile index equation corresponding to the city. And determining which cities the departure address and the destination address are respectively located in according to the departure address and the destination address, and then using a charging pile index equation corresponding to the corresponding cities to index the charging piles. The following description will be given taking as an example that the user riding request is located in the same city.
Therefore, the estimation unit 22 respectively obtains the position of the charging pile closest to the departure address and the position of the charging pile closest to the destination address according to the departure address and the destination address in the riding request of the user through the charging pile index equation. After the estimation unit 22 respectively obtains the locations of the charging piles closest to the departure address and the destination address, the distance calculation equation is used for obtaining the distance between the departure address and the nearest charging pile according to the departure address and the charging pile location closest to the departure address, and obtaining the distance between the destination address and the nearest charging pile according to the destination address and the charging pile location closest to the destination address.
The calculation equation of the distance between the departure place address and the nearest charging pile is as follows:
dsp＝f2[(xs,ys),p(n)]
in the formula: dspRepresenting the distance between the departure address and the nearest charging pile, (x)s,ys) And p (n) represents the position coordinate of the starting place address, and the position coordinate of the charging pile closest to the starting place address.
The calculation equation of the distance between the destination address and the nearest charging pile is as follows:
dep＝f2[(xe,ye),p(m)]
in the formula: depRepresents the distance between the destination address and the nearest charging pile (x)e,ye) And p (m) represents the location coordinates of the nearest charging post to the destination address.
After the estimation unit 22 obtains the distance from the departure address to the nearest charging pile, the passenger riding distance from the departure address to the destination address and the distance from the destination address to the nearest charging pile, the fare estimation can be performed on the riding request of the user by using the estimation equation. The fare estimation equations used by the estimation unit 22 are:
Cost＝ω0’*dse+ω3*dep
in the formula: cost is an estimated fare, omega0' is a second unit price, dseFor passenger riding distance, omega3Is a third unit price, depThe distance between the destination address and the nearest charging pile.
Cost＝ω0’*dse+ω4*dsp
In the formula: cost is an estimated fare, omega0' is a second unit price, dseFor passenger riding distance, omega4Is a fourth unit price, dspThe distance between the destination address and the nearest charging pile.
When estimating the fare according to the riding request of the user, the estimating unit 22 needs to select a suitable estimating equation to estimate the fare by combining the remaining driving distance of the vehicle, the riding distance of the passenger and the current electric quantity of the vehicle. Therefore, the estimation unit 22 needs to acquire the current amount of power of the vehicle and the remaining travel distance of the vehicle.
The current electric quantity of the vehicle obtained by the estimation unit 22 is the current remaining electric quantity of the vehicle. The estimation unit 22 estimates the distance that the vehicle can travel according to the current electric quantity of the vehicle through a vehicle remaining travel distance estimation equation. The estimation equation of the vehicle remaining travel distance is obtained in advance according to the vehicle electric quantity and the historical data of the vehicle remaining travel distance, and the estimation equation is as follows:
dt＝f3(pt)
in the formula: dtRepresenting the remaining distance of travel of the vehicle at time t, ptRepresenting the remaining capacity of the vehicle at time t.
If the remaining driving distance of the vehicle obtained by the estimation unit 22 is greater than the passenger riding distance and the current electric quantity of the vehicle is greater than 50% of the full electric quantity, the estimated fare equation is a common billing equation:
Cost＝ω0*dse
in the formula: cost is an estimated fare, omega0Is a first unit price, dseFor passenger riding distance.
If the remaining driving distance of the vehicle obtained by the estimation unit 22 is greater than the passenger riding distance, but the current electric quantity of the vehicle is less than 50% of the full electric quantity, the estimated fare equation is:
Cost＝ω0’*dse+ω3*dep
if the remaining driving distance of the vehicle obtained by the estimation unit 22 is less than the passenger riding distance, the estimated fare equation is:
Cost＝ω0’*dse+ω4*dsp
wherein the first unit price ω0Conventionally charging prices for the market; second unit price ω0' less than the first unit price is satisfied; third unit price ω3And a fourth unit price ω4Can be preset valueAnd dynamic assignment can be distributed according to the departure place address and the charging piles near the destination address.
For example, the third unit price ω3Fourth unit price ω4When dynamic assignment is performed according to the distribution of the charging piles near the departure address and the destination address, the assignment formulas can be respectively as follows:
ω3＝(dep/dse)*ω0’
ω4＝(dsp/dse)*ω0’
in the formula: depThe distance of the destination address from the nearest charging pile, dseFor passenger riding distance, dspDistance, omega, of destination address from nearest charging pile0' is the second unit price.
When the passenger riding distance is greater than the distance between the departure address and the nearest charging pile and the distance between the destination address and the nearest charging pile, the estimation unit 22 estimates the fare of the user riding request by using different estimation equations through judging the magnitude relation between the residual driving distance of the vehicle and the passenger riding distance and the magnitude relation between the current electric quantity of the vehicle and 50% of the full electric quantity of the vehicle, and obtains the estimated fare. If the obtained passenger riding distance is smaller than the distance between the departure address and the nearest charging pile or the distance between the destination address and the nearest charging pile, or the passenger riding distance is smaller than both the distance between the departure address and the nearest charging pile and the distance between the destination address and the nearest charging pile, the estimation unit 22 cannot estimate the fare by using the estimation equation.
And the feedback unit 23 is configured to feed back the obtained estimated fare to the client.
If the estimated fare is obtained by the estimating unit 22 according to the riding request of the user, the obtained estimated fare is fed back to the client through the feedback unit 23, and the client can present the obtained estimated fare to the user in a display or voice mode. If the estimation unit 22 cannot estimate the fare by using the corresponding estimation equation according to the riding request of the user, the feedback unit 23 returns the result that the fare cannot be estimated to the client, and the client can feed back the fare that cannot be estimated to the user in a display or voice mode and can inform the reason.
