Abstract
A method for controlling depressurization of a fuel system mounted on board of a vehicle including a vehicle impact sensor, the method including: detecting, using the vehicle impact sensor, whether an impact on the vehicle is present; and when the impact on the vehicle is detected, using a controller for generating at least one signal for controlling an opening of at least one valve disposed in the fuel system, to release internal pressure of the fuel system.

22. A method for controlling depressurization of a fuel system mounted on board of a vehicle, the vehicle including a fuel tank connected in a communicating manner to a canister, and a vehicle impact sensor, the method comprising:
-
detecting, using the vehicle impact sensor, whether an impact on the vehicle is present; and when the impact on the vehicle is detected, using a controller for generating at least one signal for controlling an opening of at least one valve disposed in the fuel system, to release internal pressure of the fuel system; wherein the controller generates a first signal for controlling opening of a fuel tank isolation valve, to allow fuel vapors within the fuel tank to flow towards the canister; and wherein the fuel tank isolation valve is disposed in a first venting line through which the canister can communicate with the atmosphere. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 37)

31. A fuel system of a vehicle comprising:
-
a controller for generating at least one signal for controlling an opening of at least one valve disposed in the fuel system, to release internal pressure of the fuel system when an impact on the vehicle is detected; a fuel tank isolation valve and a first venting line through which the canister can communicate with the atmosphere; wherein the controller is configured to generate a first signal for controlling opening of the fuel tank isolation valve, to allow fuel vapors within the fuel tank to flow towards the canister; and wherein the fuel tank isolation valve is disposed in the first venting line through which the canister can communicate with the atmosphere. - View Dependent Claims (32, 33, 34, 35, 36, 38, 39, 40, 41, 42)
