Abstract

A method and system for controlling the start of a vehicle are provided. The method includes determining whether a high voltage battery of a vehicle is submerged and outputting a warning regarding the submersion when the high voltage battery is submerged. In addition, power is cut off and the vehicle ignition or the start of the vehicle is turned off after the warning signal is output.

First claim

What is claimed is:

1. A method for controlling the start of a vehicle, comprising:
determining, by a controller, whether a high voltage battery of a vehicle is submerged;
warning and outputting, by the controller, a warning signal when the high voltage battery is submerged;
cutting off power and turning OFF the vehicle ignition or start of the vehicle after outputting the warning signal, by the controller; and
determining, by the controller, whether the vehicle is driving after outputting the submersion warning when the high voltage battery is submerged,
wherein the submersion determination includes a first submersion determination for determining whether the high voltage battery is submerged when the ignition of the vehicle is turned ON, and
wherein the submersion determination a second submersion determination for determining whether the high voltage battery is submerged when the start of the vehicle is turned ON.

2. The method for controlling the start of a vehicle of claim 1 , further comprising:
turning start ON, by the controller, when the high voltage battery is not submerged as a result of performing the first submersion determination.

3. The method for controlling the start of a vehicle of claim 1 , wherein when the vehicle is driving, a driving power of the vehicle is decreased.

4. The method for controlling the start of a vehicle of claim 1 , wherein when the vehicle is stopped, the power is cut off by the controller.

5. The method for controlling the start of a vehicle of claim 1 , wherein when the power is cut off, the connection between the high voltage battery and the high voltage device is cut off by the controller.

6. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
program instructions that operate a sensor system to determine whether a high voltage battery of a vehicle is submerged;
program instructions that warn and output a warning signal when the high voltage battery is submerged;
program instructions that cut off turn OFF the vehicle ignition or start of the vehicle after outputting the warning signal; and
program instuctions that determine whether the vehicle is driving after outputting the submersion warning when the high voltage battery is submerged,
wherein the submersion determination includes a first submersion determination for determining whether the high voltage battery is submerged when the ignition of the vehicle is turned ON, and
wherein the submersion determination a second submersion determination for determining whether the high voltage battery is submerged when the start of the vehicle is turned ON.

7. The non-transitory computer readable medium of claim 6 , further comprising:
program instructions that turn start ON when the high voltage battery is not submerged as a result of performing the first submersion determination.

8. The non-transitory computer readable medium of claim 6 , wherein when the vehicle is driving, a driving power of the vehicle is gradually decreased for a preset time, and the power is cut off by the controller when the driving power of the vehicle is removed.

9. The non-transitory computer readable medium of claim 6 , wherein when the vehicle is stopped, the power is cut off by the controller.

10. The non-transitory computer readable medium of claim 6 , wherein when the power is cut off, the connection between the high voltage battery and the high voltage device is cut off by the controller.
