  • Patent number: 9446773
    Abstract: A system and method for assisting a driver are provided. The method includes receiving, by a controller, vehicle traveling information and calculating a first distance between a present vehicle position and an end node. In addition, the controller is configured to calculate a second distance between the present vehicle position and a preceding vehicle based on the receiving information and calculate a third distance in which coasting is available until a present vehicle speed reaches a predetermined target speed. The method further includes determining, by the controller, whether coasting is available based on the first distance, the second distance, the third distance in which coasting is available, and a present vehicle speed of the vehicle, and outputting, when coasting is available, a message that instructs coasting.

  • Patent number: 9114727
    Abstract: A system and a method of assisting a driver in driving an electric vehicle in a more environmentally efficient manner are disclosed. In particular, an information collecting section collects information operating the electric vehicle and a control logic section generates control logic and models related to route calculation to a destination and operation of the electric vehicle based on the collected information. A route setting section calculates a plurality of travel routes based on the control logic and the model related to the route calculation and sets an optimum travel route having the highest energy efficiency among the plurality of travel routes. A vehicle driving controller monitors the vehicle state and controls driving of the electric vehicle based on the control logic and the model related to the driving of the electric vehicle when the electric vehicle travels along the optimum travel route set by the route setting section.

  • Patent number: 8924146
    Abstract: Disclosed is drive mode guide system for a vehicle provided with a plurality of drive modes. More specifically, a road information storage unit stores information related a road state. A real-time information storage unit receives and stores environmental information in real time. A vehicle information storage unit stores information related to the vehicle. A control unit then extracts a possible-traveling path and a drive mode and an outputs the possible-traveling path. A suggested drive mode received from the control unit based on the information stored in the road information storage unit, the real-time information storage unit, and the vehicle information storage unit.

  • Publication number: 20130325335
    Abstract: The present disclosure provides a method for determining an eco-route using a state of charge (SOC) consumption ratio that includes an eco-driving logic for an electric vehicle configured to apply a cost function to select an eco-route in a navigation system, decide an optimal eco-route of the cost function from an SOC ratio map having information on a mileage with respect to an SOC consumption ratio, and provide the determined optimal eco-route as a travel route of the electric vehicle.

  • Publication number: 20130151046
    Abstract: An eco driving system for an electric vehicle and a method thereof is disclosed. The eco driving system may include: a route generator that generates at least one candidate route from a current position to a destination; an information collector that collects real time traffic information, weather information, and an air conditioning load of the vehicle; an energy consumption amount calculator that calculates energy consumption amount of each candidate route based on 3D geographical information of the candidate route and the real time traffic information, the weather information, and the air conditioning load of the vehicle; a driver tendency detector that analyzes a driver's driving pattern to determine the driving tendency; a data base portion that stores each program and data for guiding the eco driving; and a control portion that selects an echo driving route from the candidate routes corresponding to the driving tendency.
