An electric pump for a vehicle includes a pump body that is divided into a motor room and a pump room, a shaft that is connected to the motor room and the pump room and a sealing unit is interposed therebetween, and an impeller that is mounted on the shaft in the pump room. The pouch has a sealed flowable-type material containing compartment between opposed film walls which are sealed along opposed parallel edges thereof. When a multipath condition is detected, the signal is processed using a second resolution. When the integrated value of saturating amount reduces to a predetermined value or less, a control mode is switched to feedback control.
