Abstract:
1. A hybrid vehicle comprising: an engine configured to output driving power, the engine including a purification device having a purification catalyst that purifies exhaust gas, the purification device being installed in an exhaust system; a motor configured to output driving power; a battery configured to exchange electric power with the motor; a navigation system configured to set a travel route to a destination and carry out route guidance; and a controller configured to set a travel plan in which each of travel sections in the travel route to the destination, set by the navigation system, is determined as one of a hybrid traveling priority section and an electric traveling priority section on the basis of a traveling load, the hybrid traveling priority section being a section in which the hybrid vehicle travels while the engine is operated is carried out in preference to electric traveling in which the hybrid vehicle travels while operation of the engine is stopped, the electric traveling priority section being a section in which the electric traveling is carried out in preference to the hybrid traveling, the controller being configured to set a predetermined section, which is an initial section of the hybrid traveling priority section in the travel plan, for a warm-up section for warming up the purification device, the controller being configured to reset the travel plan by changing any one of the electric traveling priority sections before the predetermined section to the hybrid traveling priority section when the traveling load of the predetermined section is higher than a predetermined load corresponding to an output limit of the battery, the controller being configured to reset the section changed to the hybrid traveling priority section for the warm-up section for warming up the purification device, the controller being configured to keep the travel plan and the warm-up section of the purification device when the traveling load of the predetermined section is lower than or equal to the predetermined load, the controller being configured to control the engine and the motor such that the purification device is warmed up when the hybrid vehicle travels on the driving power and travels in the warm-up section for warming up the purification device in accordance with the set travel plan.
