1. A running profile generation device comprising:

  • a storage that stores speed limit information, vehicle performance information of a vehicle, and route information; and

    a processor which is configured to;

    acquire, from the storage, at least one speed limit section of a running section being set based on a departure point and an arrival point of the running section, the speed limit section being a section delimited at positions at which a speed limit changes;

    determine a base point based on a terminal position and an upper limit speed of the speed limit section and generate a reverse coasting curve from the base point based on the vehicle performance information and the route information stored in the storage, the upper limit speed being set according to a speed limit for the speed limit section;

    determine a coasting start position based on the generated reverse coasting curve;

    generate a running profile by performing a running simulation based on the set running section, the speed limit information on the running section, the generated reverse coasting curve, the set coasting start position, and the vehicle performance information and the route information stored in the storage; and

    output the generated running profile to control running of the vehicle,wherein the processor sets a range below the upper limit speed as a coasting range and sets a range equal to or above the upper limit speed to the upper limit speed during coasting from the base point toward the departure point.
