First Claim
1. A route planning device for planning a driving route for an electric vehicle, comprising:
- a processing unit including a computer, the processing unit being configured to;
upon receiving a position information of a destination, plan one or more driving routes from a current location to the destination,calculate an amount of electricity consumed by a motor mounted in the electric vehicle during driving to the destination along each of the planned routes, for each of a plurality of drive modes each having different condition of controlling the motor,calculate an amount of electricity consumed by an electric equipment mounted in the electric vehicle during a period of driving along each of the planned routes, for each of a plurality of operational settings of the electric equipment,on the basis of the calculated amount of electricity consumed by the motor and the calculated amount of electricity consumed by the electrical equipment, calculate an estimated value of an amount of charge remaining in a battery of the electric vehicle when the electric vehicle arrives at the destination,calculate a comfort level score (SSOC) for each of the estimated values of the amount of charge remaining in the battery, a comfort level score (SMODE) for each of the drive modes, and a comfort level score (SOPE) for each of the operational settings of the electrical equipment, a comfort level score (STIME) of an arrival time to the destination for each of the planned routes, and a comfort level score (SLEN) of a driving distance for each of the planned routes,calculate, for each of the planned routes, a total comfort level score for each of the drive modes and/or each of the operational settings of the electrical equipment by adding (SSOC), (SMODE), (SOPE), (STIME) and (SLEN),compare respective magnitude of the calculated total comfort level score with one another to select a plurality of operation plans with larger magnitude of the total comfort level score, each of the operation plans defined by a combination of one of the routes, one of the drive modes, and one of the operational settings of the electrical equipment anddisplay the selected operation plans on a display unit.

5. A method for planning a driving route for use in an electric vehicle, comprising:
-
planning one or more driving routes from a current location to a destination; calculating an amount of electricity consumed by a motor mounted in the electric vehicle during driving to the destination along each of the planned routes, for each of a plurality of drive modes each having different condition of controlling the motor; calculating an amount of electricity consumed by an electric equipment mounted in the electric vehicle during a period of driving along each of the planned routes, for each of a plurality of operational settings of the electric equipment; calculating, on the basis of the calculated amount of electricity consumed by the motor and the calculated amount of electricity consumed by the electrical equipment, an estimated value of an amount of charge remaining in a battery of the electric vehicle when the electric vehicle arrives at the destination; calculating, using a processor, a comfort level score (SSOC) for each of the estimated values of the amount of charge remaining in the battery, a comfort level score (SMODE) for each of the drive modes, and a comfort level score (SOPE) for each of the operational settings of the electrical equipment, a comfort level score (STIME) of an arrival time to the destination for each of the planned routes, and a comfort level score (SLEN) of a driving distance for each of the planned routes; calculating, for each of the planned routes, using the processor, a total comfort level score for each of the drive modes and/or each of the operational settings of the electrical equipment by adding (SSOC), (SMODE), (SOPE), (STIME) and (SLEN); comparing, using the processor, respective magnitude of the calculated total comfort level score with one another to select a plurality of operation plans with larger magnitude of the total comfort level score, each of the operation plans defined by a combination of one of the routes, one of the drive modes, and one of the operational settings of the electrical equipment; and displaying the selected operation plans on a display unit.
