Abstract

An apparatus for controlling a vehicle includes a battery controller, a driving controller, and a notification device, wherein the battery controller may obtain state information of a battery, calculate remaining energy of the battery, and determine whether energy of the battery is excessively consumed, and the driving controller may obtain the remaining energy and route information, calculate a remaining driving distance, and determine a fuel efficiency deterioration section.

First claim

What is claimed is:

1 . An apparatus for controlling a vehicle, the apparatus comprising:
a battery controller including a first processor; and a driving controller including a second processor; wherein the battery controller is configured to:
obtain state information of a battery;
calculate remaining energy of the battery based on the obtained state information of the battery; and
wherein the driving controller is configured to:
obtain the remaining energy and route information;
calculate a remaining driving distance based on the obtained remaining energy of the battery and the route information, wherein the remaining energy of the battery is calculated according to a heating and cooling on/off switching state; and
output information on a sudden driving distance reduction based on the remaining driving distance to notify an occupant of the vehicle of a reason why the driving distance is suddenly reduced;
wherein the information on the sudden driving distance reduction includes the reason why the driving distance is suddenly reduced;
wherein the reason why the driving distance is suddenly reduced includes rapid acceleration, heating and cooling of the vehicle, or route information;
wherein the battery controller is further configured to determine a type of driving distance reduction according to a type of energy consumption of the battery, and wherein the driving controller is further configured to analyze a route for each slope type by using the obtained route information and determine a type of route in a situation in which the driving distance decreases.

2 . The apparatus of claim 1 , wherein the battery controller is configured to monitor a state of charge (SoC) of the battery, a state of health (SoH) of the battery, and a state of power of the battery.

3 . The apparatus of claim 1 , wherein the battery controller is configured to:
calculate a first average of battery current obtained from a first time point to a second time point and a second average of speed of vehicle obtained from the first time point to the second time point; and calculate a third average of battery current obtained before the first time point and a fourth average of speed of vehicle obtained from the first time point; wherein the first average, the second average, the third average, and the fourth average are calculated for outputting information on the sudden driving distance reduction due to rapid acceleration.

4 . The apparatus of claim 3 , wherein the battery controller is configured to:
calculate a first remaining energy of the battery based on the first average and the second average; and calculate a second remaining energy of the battery based on the third average and the fourth average.

5 . The apparatus of claim 1 , wherein the driving controller is configured to calculate the remaining driving distance based on the first remining energy and the second remaining energy.

6 . The apparatus of claim 1 , wherein the battery controller is configured to:
calculate a first average of battery current obtained from a first time point to a second time point and a third average of speed of vehicle obtained from the first time point to the second time point, wherein the first average and the third average are calculated for outputting information on the sudden driving distance reduction due to heating and cooling of the vehicle.

7 . The apparatus of claim 6 , wherein the battery controller is configured to:
calculate a third remaining energy of the battery based on the first average when the heating and cooling on/off switching state is off; and calculate a fourth remaining energy of the battery based on the third average when the heating and cooling on/off switching state is on.

8 . The apparatus of claim 7 , wherein the driving controller is configured to calculate the remaining driving distance based on the third remaining energy and the fourth remaining energy.

9 . The apparatus of claim 1 , wherein the driving controller is configured to calculate a ratio of an uphill section based on the route.

10 . The apparatus of claim 9 , wherein the driving controller is configured to calculate a first remaining driving distance that does not consider the route information and a second remaining driving distance that considers the route information.

11 . The apparatus of claim 10 , wherein the information on the sudden driving distance reduction is output based on a comparison result of the first remaining driving distance and the second remaining driving distance.

12 . A method of controlling an apparatus for controlling a vehicle, the method comprising:
obtaining, by a battery controller of the apparatus for controlling the vehicle, state information of a battery; calculating, by the battery controller, remaining energy of the battery based on the obtained state information of the battery; obtaining, by a driving controller of the apparatus for controlling the vehicle, the remaining energy and route information; calculating, by the driving controller, a remaining driving distance based on the obtained remaining energy of the battery and the route information, wherein the remaining energy of the battery is calculated according to a heating and cooling on/off switching state; and outputting, by the driving controller, information on a sudden driving distance reduction based on the remaining driving distance to notify an occupant of the vehicle of a reason why the driving distance is suddenly reduced; wherein the information on the sudden driving distance reduction includes the reason why the driving distance is suddenly reduced; and wherein the reason why the driving distance is suddenly reduced includes rapid acceleration, heating and cooling of the vehicle, or route information; the method further comprising: determining, by the battery controller, a type of reduction in the driving distance according to a type of energy consumption of the battery; analyzing, by the driving controller, a route for each slope type using the obtained route information; and determining, by the driving controller, a type of route in a situation in which the driving distance decreases.

13 . The method of claim 12 , further comprising monitoring, by the battery controller, a state of charge (SoC) of the battery, a state of health (SoH) of the battery, and a state of power of the battery.
