1. Field
Apparatuses and methods consistent with exemplary embodiments relate to controlling travel of a vehicle in which a driving mode of the vehicle is determined based on the speed of the vehicle and a user-selected driving mode, and more particularly to controlling travel of the vehicle when a failure occurs in a power supply that supplies the vehicle with power according to the determined driving mode, the power supply is replaced with another power supply for stable driving.
2. Description of the Related Art
Japanese Patent Application Publication No. 2003-032807 discloses that a vehicle is switched by a hybrid vehicle control device between an electric vehicle (EV) mode in which the vehicle travels by using a battery alone, an engine mode in which the vehicle travels by using an engine alone, and a hybrid electric vehicle (HEV) mode in which the vehicle travels by using the battery and the engine together according to stored road data.
Such related art technology merely enables a switch between the three driving modes based on road data, and does not reflect the output or battery/engine state of a vehicle. In addition, a means and method for storing data about a driving region are necessary for the related art. In other words, the related art will reach to the limit of storage capacity and involve additional cost for the storage means.
