Note that the data for constructing the vehicle database 24 is not limited to that shown in FIG. 3, and other data may be added or only necessary data may be used according to the use conditions of the vehicle.

<Fuel consumption conversion data based on vehicle weight>
The vehicle weight that is the basis of calculation of fuel consumption conversion data based on the vehicle weight (hereinafter referred to as weight fuel consumption) is the sum of the weight of the vehicle body, the weight of the occupant, and the weight of the load. Here, in order to facilitate the calculation, the weight of the occupant is calculated by the average weight of an adult 50 kg × the number of passengers, and the weight of the load is large (50 kg), medium (25 kg), small ( 10 kg). The amount of fuel replenished is the volume of fuel replenished at a gas station near the garage just before returning.

In the present invention, the fuel efficiency of an automobile equipped with a gasoline engine or a diesel engine is assumed as a basic heavy fuel economy. Hereinafter, a calculation example of the weight fuel consumption will be described.
The fuel consumption conversion data based on the vehicle weight can be calculated by the following formula 1.
Weight fuel consumption (kg · km / liter) = vehicle weight (kg) × travel distance (km) ÷ fuel supply amount (liter)

<Calculation example / gasoline engine vehicles, etc.>
First, calculation examples of heavy fuel consumption and fuel consumption will be described for an automobile equipped with a gasoline engine or a diesel engine.
Vehicle body weight: 500kg vehicle, first day results: 4 passengers, loaded luggage: large, mileage: 20km, second day results, passengers: 2 persons, loaded luggage : Large, mileage: 40 km, fuel consumption for 2 days is 5 liters, weight fuel economy is as follows.
Total weight on day 1 = {500+ (4 × 50) +50} = 750 (kg)
Total weight on the second day = {500+ (2 × 50) +50} = 650 (kg)
Heavy fuel consumption = {(750 × 20) + (650 × 40)} ÷ 5 = 8200 (kg · km / liter)

The fuel efficiency in the case of a vehicle having such a heavy fuel efficiency is as follows.
The fuel consumption in the case of a single passenger and no luggage (vehicle weight: 550 kg) can be converted to 8200 ÷ 550≈14.9 (km / liter). Further, the fuel efficiency in the case of four passengers and a large luggage (vehicle weight: 750 kg) can be converted to 8200 ÷ 750≈10.9 (km / liter).

<Calculation example / electric vehicle>
Next, calculation examples of heavy fuel consumption and fuel consumption for an electric vehicle will be described.
Vehicle body weight: 1100kg vehicle, first day results: 2 passengers, loaded luggage: small, mileage: 20km, second day results: passengers: 2 persons, loaded luggage : Small, traveling: 20 km, and when the electricity consumption for 2 days is 5 kWh, the fuel economy is as follows.
Total weight of the first day = {1100+ (2 × 50) +10} = 1210 (kg)
Total weight on the second day = {1100+ (2 × 50) +10} = 1210 (kg)
Heavy fuel consumption = {(1210 × 20) + (1210 × 20)} ÷ 5 = 9680 (kg · km
/ KWh)

In the case of an electric vehicle, the calculated unit of weight fuel consumption is different. Therefore, when comparing the weight and fuel consumption of an electric vehicle and a vehicle equipped with a gasoline engine, it is necessary to convert them.
For example, assuming that the following vehicle is owned, the conversion of fuel consumption will be described.
Vehicle X: 8000 kg / km / liter (vehicle body weight: 500 kg)
Vehicle Y: 7000 kg / km / liter (vehicle body weight: 500 kg)
Vehicle Z: 9000 kg · km / kWh (vehicle weight: 1100 kg)

Here, Mr. A loaded a large baggage (total weight 250 kg) with a four-person ride and traveled 20 km, and Mr. B loaded a large baggage (total load 150 kg) with a two-person ride, 40 km Let's say that Mr. C traveled 40 km with a small passenger (total weight of 150 kg) loaded with two passengers.
In this case, the fuel consumption in the case of each vehicle is as follows.

When Mr. A uses the vehicle X (body weight: 500 kg), the fuel of 750 (kg) × 20 (km) ÷ 8000 (kg · km / liter) = 1.875 (liter) will be used. Is converted into raw fuel (kWh),
1.875 (liter) x 0.75 (gasoline specific gravity) x 44000 (kj / kg: calorific value of gasoline) ÷ 3600 ÷ 82 (%: refined transport rate) ≒ 20.960 (kWh)
It becomes.

When Mr. B uses the vehicle Y (body weight: 500 kg), the fuel of 650 (kg) x 40 (km) ÷ 7000 (kg · km / liter) ≒ 3.714 (liter) will be used. Is converted into raw fuel (kWh),
3.714 (liter) x 0.75 (gasoline specific gravity) x 44000 (kj / kg: calorific value of gasoline) ÷ 3600 ÷ 82 (%: refined transport rate) ≒ 41.518 (kWh)
It becomes.

When Mr. C uses the vehicle Z (body weight: 1100 kg), the fuel of 1210 (kg) x 40 (km) ÷ 9000 (kg · km / kWh) ≒ 5.377 (kWh) will be used. Is converted into raw fuel (kWh),
5.377 (kWh) ÷ 83 (%: charging efficiency) ÷ 43 (%: refining / power generation / transmission rate) ≈15.066 (kWh)
It becomes.

<Usage condition acquisition means>
The use condition acquisition means 21 is a means for acquiring the use conditions related to the total load weight and travel distance required for the reserved vehicle as essential data when making a reservation for use of the vehicle. This is realized as a function of the management computer 100. Moreover, it is good also as a structure which acquires the data regarding the maximum loading capacity requested | required of a reservation vehicle, boarding capacity, equipment, and a drive system as other additional data.

  The use condition data is input by the vehicle driver. That is, data may be input using the input device 15 such as a keyboard or a mouse for each item on the use condition input screen displayed on the display device that is the output device 16. For example, as shown in FIG. 4, the use condition input screen includes a use date and time, a user name, a passenger, the size of the load, necessary equipment, and the like. When data is input on this use condition input screen and the transmission button is clicked, the use condition is acquired by the function of the use condition acquisition means 21 in the management computer 100.

<Reserved vehicle identification means>
The reserved vehicle specifying unit 22 refers to the vehicle database 24 and is a unit for specifying a vehicle having the best fuel efficiency calculated based on the acquired use condition as a reserved vehicle. In addition, when the reserved vehicle is specified by adding attribute information other than the fuel efficiency, the vehicle database 24 is referred to, and based on the maximum load capacity, the riding capacity, the equipment, and the driving method required for the reserved vehicle. A vehicle group that can be selected as a reserved vehicle is identified, and a vehicle having the best fuel efficiency calculated based on the total load weight and travel distance required for the reserved vehicle is selected from the identified vehicle group. As specified.

First, the case where the reserved vehicle is specified by the reserved vehicle specifying means 22 based only on the fuel consumption will be described.
For example, assume that you have the following vehicles:
Vehicle X: 8000 kg / km / liter (vehicle body weight: 500 kg)
Vehicle Y: 7000 kg / km / liter (vehicle body weight: 500 kg)

  Here, Mr. A loads four pieces of luggage (total vehicle weight 750 kg) and travels 20 km. Mr. B loads two passengers and loads large (total vehicle weight 650 kg), and 40 km. Assume a case of traveling.

  When Mr. A uses the vehicle X, fuel of 750 (kg) × 20 (km) ÷ 8000 (kg · km / liter) = 1.875 (liter) is used. On the other hand, when Mr. B uses the vehicle Y, fuel of 650 (kg) × 40 (km) ÷ 7000 (kg · km / liter) ≈ = 3.714 (liter) is used. Therefore, the total fuel used in the vehicle X and the vehicle Y is 5.589 (liter) (case 1).

  Further, when Mr. A uses the vehicle Y, the fuel of 750 (kg) × 20 (km) ÷ 7000 (kg · km / liter) ≈ = 2.143 (liter) is used. On the other hand, when Mr. B uses the vehicle X, fuel of 650 (kg) × 40 (km) ÷ 8000 (kg · km / liter) = 3.250 (liter) is used. Therefore, the total fuel used in the vehicle X and the vehicle Y is 5.393 (liter) (case 2).

  Here, when only Mr. A has applied for use, when comparing Case 1 and Case 2, Case 1 is selected because the fuel efficiency of Case 1 is advantageous. That is, the vehicle X is specified as the vehicle used by Mr. A.

  In addition, when A and B apply for use on the same day, Case 2 with less total fuel used is selected. That is, the vehicle Y is specified as the vehicle used by Mr. A, and the vehicle X is specified as the vehicle used by Mr. B.

<Identification of reserved vehicles including other factors>
Next, a case where the reserved vehicle is specified by the reserved vehicle specifying unit 22 based on other conditions in addition to the fuel consumption will be described.
In the specific example of the reserved vehicle described above, the reserved vehicle is specified by comparing only the fuel consumption. However, when other use conditions are specified, the vehicle that matches the use condition is specified. . For example, assuming that the vehicle database 24 shown in FIG. 3 is constructed and the usage condition is that an ETC device is essential, the vehicle W on which the ETC device is mounted is specified as the usage vehicle. In the use condition that a four-wheel drive vehicle is essential, the vehicle X that is a four-wheel drive vehicle is specified as the use vehicle.

  When the vehicle database 24 shown in FIG. 3 is constructed, the usage conditions for specifying the reserved vehicle include loading capacity, presence / absence of ETC equipment, presence / absence of car navigation equipment, driving method, presence / absence of loudspeakers, The number of effective occupants can be used. The use conditions for specifying the reserved vehicle are not limited to these, and other use conditions may be added according to the use conditions of the vehicle, or only necessary use conditions are used. May be.

<Vehicle weight fuel consumption calculation means>
