  • Patent number: 10457267
    Abstract: A controller controls a valve device for opening and closing of a passage to control a flow of evaporative fuel evaporating and flowing from a fuel tank. The valve device includes a valve body housed in the passage to open and close the passage, a biasing member biasing the valve body to close the passage, and a driver driving the valve body to open the fuel passage. The controller includes a detector detecting load of the driver and a determiner to determine the position of the valve body. The determiner determines that the passage is open when a magnitude of the change of the driver load is equal to or greater than a threshold value. The controller accurately detects an open valve position without detecting an internal pressure change of the fuel tank.
