1. A control device of a vehicle, the vehicle including:
a power storage device; and
an electric motor connected to a drive wheel, driven by being supplied with electric power of the power storage device, and configured to supply regenerative electric power generated by a regenerative operation to the power storage device,
the control device comprising:
a discharge control pit configured to, in a case where a regenerative section in which the electric motor is able to perform the regenerative operation is included in a scheduled traveling route of the vehicle, perform a discharge control for discharging the electric power from the power storage device before the vehicle reaches a start point of the regenerative section based on a remaining capacity of the power storage device and a predicted regenerative electric power amount in the regenerative section,
wherein the discharge control unit is configured to,
in a case where a plurality of regenerative sections are included in the scheduled traveling route, extract a first regenerative section on a vehicle side in the plurality of regenerative sections, a second regenerative section closest to the first regenerative section in a traveling direction of the vehicle in the plurality of regenerative sections, and a dischargeable section between the first regenerative section and the second regenerative section,
in a case where a predicted regenerative electric power amount in the first regenerative section is greater than a predicted discharge electric power amount in the dischargeable section, set a section obtained by merging the first regenerative section, the second regenerative section, and the dischargeable section as a control target section that is regarded as one regenerative section, and
perform the discharge control before the vehicle reaches a start point of the control target section based on the remaining capacity of the power storage device and a predicted regenerative electric power amount in the control target section.
