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.

The present invention relates to a power control method and terminal device for a hydraulic hybrid vehicle, and a storage medium. The method includes: S1: predicting, according to environmental information of a road ahead, recoverable energy in the road ahead; S2: calculating, according to the predicted recoverable energy, a critical pressure required by a hydraulic accumulator to recover the recoverable energy; and S3: determining whether a current pressure of the hydraulic accumulator is greater than the critical pressure, and if so, reducing fuel output power of an engine and controlling the hydraulic accumulator to release energy such that the current pressure of the hydraulic accumulator is less than or equal to the critical pressure. According to the present invention, when it is predicted that there is a high probability of energy recovery ahead, the energy stored in the hydraulic accumulator is used up in advance, so that the hydraulic accumulator has enough space to recover energy when the energy recovery occurs in future. This can make full use of the characteristic of the hydraulic accumulator of being suitable for frequent storage and release of energy, thereby achieving the economy of energy consumption of the whole vehicle.
