Provided is a fuel tank system wherein the liquid levels of fuel in two fuel storage portions can be equally maintained, and the fuel amount in each fuel tank can be estimated with a high degree of accuracy. The fuel tank system is provided with a fuel tank in which a main tank portion and a subsidiary tank portion are formed; a siphon tube which extends from the main tank portion to the subsidiary tank portion, to transfer fuel from one tank portion to the other tank portion; and an electronic control unit (ECU) for determining whether or not the fuel is transferred via the siphon tube (in the transfer state). The ECU determines that the fuel is in the transfer state when the change rate of a sender signal is equal to or less than a predetermined threshold value (VF_th).

The present invention provides a driving mode changing device. The driving mode changing device includes a storage unit for storing three or more driving modes including a normal mode and other modes, an input unit for selecting and inputting an arbitrary one from among the driving modes, and a control unit for changing setup of a plurality of driving control devices installed in a vehicle according to the driving mode input from the input unit. The input unit includes one operating member. The operating member is biased from a stationary position when no operation is performed so as to enable a push operation, and simultaneously biased from the stationary position to a predetermined turned position so as to enable a turn operation. The control unit switches the drive mode from the normal mode to a predetermined driving mode, which is different from the normal mode, among the driving modes when detecting that the operating member is pushed at the stationary position, and switches to the other driving mode different from the normal mode and the predetermined driving mode when detecting that the operating member is continuously held at the turned position for a predetermined time in the state where the predetermined driving mode is selected.
