Abstract
A travel route guide device includes a travel route calculation unit that calculates a travel route from a current position to a destination based on current position information, destination information, and a remaining amount of power of an electric vehicle, and information on a remaining power amount recovery facility. The travel route guide device includes a region division unit that divides a region including the travel route calculated by the travel route calculation unit into a plurality of local regions. The travel route device includes a constraint condition determination unit that determines a constraint condition for a monitoring variable. The travel route device includes a recalculation determination unit that monitors the monitoring variable corresponding to the local region including a position of the electric vehicle, and requests the travel route calculation unit to calculate the travel route when a value of the monitoring variable deviates from the constraint condition.
