A travel route from the current location to the destination is divided into a plurality of sections. Travel modes of a vehicle include an EV mode, which uses the motor as the drive source, and an HV mode, which uses at least the internal combustion engine as the drive source. A road load for traveling each section in the EV mode is set. A travel support device includes a planner and a setter. The planner plans, for each section, the travel mode by selecting one of the EV mode, and an HV mode. When a planned section of the travel mode is switched from an EV mode-planned section to an HV mode-planned section, the setter sets the travel mode to continue traveling in the EV mode, on the condition that a remaining charge of the battery is less than a threshold.
