Abstract
A vehicle is controlled such that a driving mode of the vehicle is automatically selected, where the vehicle can be a Plug-In Hybrid Electric Vehicle (PHEV). The vehicle automatically selects an optimum driving mode from among various driving modes capable of being selected by the PHEV according to a driving situation based on a destination established by a driver who uses a navigation system, or recommends various driving modes to the driver, resulting in increased convenience of use. Through selection of an appropriate driving mode, the vehicle can be driven with superior fuel efficiency, resulting in increased driving efficiency.
Claims15
A vehicle comprising:
- a battery;
- a battery sensor configured to measure a State of Charge (SOC) of the battery;
- an Audio Video Navigation (AVN) device configured to establish a destination by a driver who rides in the vehicle;
- and
- a controller configured to calculate a distance to the destination by analyzing information regarding a route to the established destination, and calculate an Electric Vehicle (EV) available range according to a level of the SOC of the battery,
- wherein the controller selects a driving mode by comparing the distance to the destination with the EV available range,
- wherein the driving mode includes:
- an electric vehicle (EV) mode in which the vehicle is driven only using electrical power of a motor;
- a hybrid electric vehicle (HEV) mode in which the vehicle is driven using a combination of engine power and the electrical power according to the SOC level;
- and
- an automatic (AUTO) mode in which the vehicle is driven using distribution of the engine power and the electrical power according to the SOC level, and
- wherein the controller compares the distance to the destination with the EV available range, and recommends the driving mode to the driver.
A vehicle configured to be driven using at least one of engine power and electrical power of a motor, comprising:
- a battery configured to supply drive energy of the motor;
- a battery sensor configured to measure a State of Charge (SOC) of the battery;
- an Audio Video Navigation (AVN) device configured to search for a route to a destination established by a driver who rides in the vehicle;
- and
- a controller configured to calculate a distance to the destination by analyzing the searched route information, and calculate an Electric Vehicle (EV) available range according to a level of the SOC of the battery,
- wherein the controller selects a driving mode on the basis of the route analysis result and the calculated EV available range,
- wherein the controller recommends the driving mode to the driver on the basis of the route analysis result and the calculated EV available range, and
- wherein the driving mode includes:
- an electric vehicle (EV) mode in which the vehicle is driven only using the electrical power;
- a hybrid electric vehicle (HEV) mode in which the vehicle is driven using a combination of the engine power and the electrical power according to the SOC level;
- and
- an automatic (AUTO) mode in which the vehicle is driven using distribution of the engine power and the electrical power according to the SOC level.
A method for controlling a vehicle that includes an engine, a motor, and battery, the vehicle configured to be driven using at least one of engine power and electrical power of the motor, the method comprising:
- allowing a driver who rides in the vehicle to establish a destination through an Audio Video Navigation (AVN) device;
- calculating a distance to the destination by analyzing information regarding a route to the established destination;
- measuring a State of Charge (SOC) of the battery, and calculating an electric vehicle (EV) available range according to a level of the SOC;
- comparing the calculated distance to the destination with the calculated EV available range, and selecting a driving mode according to the result of comparison;
- and
- comparing the distance to the destination with the EV available range, and recommending the driving mode to the driver,
- wherein the driving mode includes:
- an electric vehicle (EV) mode in which the vehicle is driven only using the electrical power;
- a hybrid electric vehicle (HEV) mode in which the vehicle is driven using a combination of the engine power and the electrical power according to the SOC level;
- and
- an automatic (AUTO) mode in which the vehicle is driven using distribution of the engine power and the electrical power according to the SOC level.
