TRAVEL SUPPORT CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE

A travel support control device: creates a travel support plan in which one of travel modes including a CD mode and a CS mode is assigned to each travel section based on look-ahead information generated for a travel route to allow a hybrid electric vehicle to travel and calculates a total distance of electric traveling on the travel route; creates a travel support plan for travel sections to a travel section immediately before an information non-acquirable area in which information required for creating the look-ahead information is not acquirable and calculates the total distance of electric traveling on the travel route, when the information non-acquirable area is included in the travel route; and stops switching of the travel mode based on travel support control and continuously calculates the total distance of electric traveling on the travel route, when the hybrid electric vehicle is traveling in the information non-acquirable area.
