VEHICLE CONTROLLER, VEHICLE CONTROL SYSTEM, AND HYBRID VEHICLE

A vehicle controller includes: a prediction unit that acquires position information on a parking place where parking time is predicted to exceed a prescribed threshold value in a travel route of the hybrid vehicle; and a target setting unit that sets a target state of charge of the battery and to change setting of the target state of charge from a first state of charge to a second state of charge that is lower than the first state of charge when the hybrid vehicle satisfies an approach condition to the parking place. A charge and discharge amount of the battery when the state of charge of the battery becomes equal to or less than the second state of charge is controlled to be smaller than the charge and discharge amount of the battery when the state of charge of the battery is larger than the second state of charge.
