Abstract
An electric vehicle may include logic for drowsiness prevention via brain wave analysis of a driver. A method for controlling the electric vehicle may include determining whether a driver needs to sleep based on a result of analyzing a brain wave of the driver. The method may also include changing a destination to a sleeping area based on selection of the driver when it is determined that the driver needs to sleep. The method may further include controlling a state of charge of a battery during travel to the sleeping area or after stopping at the sleeping area and controlling a sleep environment.
Claims19
A method for controlling an electric vehicle, the method comprising:
- determining whether a driver needs to sleep based on a result of analyzing a brain wave of the driver;
- changing a destination to a sleeping area based on selection of the driver when it is determined that the driver needs to sleep;
- securing a state of charge of a battery necessary for movement to the sleeping area and the sleep of the driver;
- and
- minimizing power consumption of a selected controller when controlling a sleep temperature of the driver, wherein minimizing the power consumption includes:
- selecting essential controller required to create and maintain optimal sleep environment after the electric vehicle moves to the sleeping area and stops,
- turning off remaining controllers except for the selected controller,
- performing voltage lowering control of supplying power at a level capable of maintaining a battery state to the selected controller, and
- supplying minimum power to the selected controller after a target sleep temperature is reached.
A hybrid electric vehicle, comprising:
- a brain wave sensor configured to sense a brain wave of a driver;
- a brain wave analysis device configured to determine whether the driver needs to sleep by analyzing the brain wave sensed by the brain wave sensor;
- an information output device configured to change a destination to a sleeping area and guide the sleeping area when the driver needs to sleep;
- a battery controller configured to control a state of charge of a battery necessary for movement to the sleeping area and maintaining a sleep environment of the driver;
- and
- a power controller configured to cut off power supply to a component unnecessary for maintaining the sleep environment of the driver, wherein the power controller is configured to:
- select essential controller required to create and maintain optimal sleep environment after the hybrid electric vehicle moves to the sleeping area and stops,
- turn off remaining controllers except for the selected controller,
- perform voltage lowering control of supplying power at a level capable of maintaining a battery state to the selected controller, and
- supply minimum power to the selected controller after a target sleep temperature is reached.
