Abstract: A vehicle includes a fuel tank, a canister, a closing valve and a filler door. A control device for the vehicle includes a valve controller that performs depressurization control for decreasing a tank pressure by opening the closing valve, a door controller that issues a normal driving command to a drive unit that opens the filler door when the tank pressure becomes equal to or lower than a predetermined pressure by the depressurization control, a detector that detects an open/close state of the filler door and a determiner that determines whether or not detection by the detector can be performed. If the detection by the detector cannot be performed, the door controller issues, when the tank pressure is equal to or lower than the predetermined pressure, a forced driving command for causing the drive unit to generate output power higher than normal power preferentially to the normal driving command.

Abstract: A first pressure sensor capable of detecting pressure in a narrow pressure range with a high accuracy to detect internal pressure in the fuel tank is arranged in the fuel tank, and a second pressure sensor that is capable of detecting pressure in a wide pressure range with a low accuracy with respect to the first pressure sensor, and is capable of detecting internal pressure of the fuel tank, is arranged in vapor piping between the fuel tank and a tank blocking valve. When a filler lid switch is operated to release internal pressure of the fuel tank, the first pressure sensor detects internal pressure of the fuel tank so that an operation of the tank blocking valve is controlled on the basis of the detection result, and then a filler lid is opened when the internal pressure of the fuel tank becomes the atmospheric pressure.

Abstract: A fuel evaporative emission control device including an electronic control unit that, when fuel tank inner pressure exceeds a first predetermined pressure, performs tank purge of closing a bypass valve and opening a sealing valve, discharging fuel evaporative gas inside the fuel tank into an air intake path of an engine in an operated state through a purge pipe and a vapor pipe, and treating the fuel evaporative gas, where, when tank purge is performed, if a first predetermined period of time passes after closing of the bypass valve without the fuel tank inner pressure falling to or below the first predetermined pressure, the sealing valve is closed and tank purge is stopped.

Abstract: A fuel filler lid device is capable of protrusion and movement and has a door hook which locks a fuel filler lid in a closed state by being urged in an extending direction by a spring and unlocks the fuel filler lid by being contracted/operated by a door motor. A wall portion that regulates extension of the door hook at a first position in a state locked by the door hook at a closed position is provided on the fuel filler lid. If a sensor detects that the door hook is at the first position for a predetermined time, it is determined that the fuel filler lid is in the closed state, while the sensor detects that the door hook is at a second position protruding more than the first position for a predetermined time, it is determined that the fuel filler lid is in an open state.

Abstract: A control unit diagnoses a failure of a fuel storage unit that seals a fuel tank and a processing unit that processes fuel evaporative gas in the fuel tank. A first pressure detection unit of the fuel storage unit detects the pressure of the fuel tank. A second pressure detection unit of the fuel storage unit is disposed at a position different from the first pressure detection unit, and detects the pressure of the fuel tank. The control unit specifies a failure portion of the fuel storage unit and the processing unit based on a change in either one or both of a first pressure value detected by the first pressure detection unit and a second pressure value detected by the second pressure detection unit when the pressure of the fuel tank is changed.
