Fuel supplying controller

摘要

A fuel supplying controller detecting a clogging of a fuel filter includes a period setting portion setting a non-detection period where a clogging detection is prohibited, an ambient-temperature detection portion detecting an ambient temperature of an exterior of a vehicle, and a residual-fuel detection portion detecting a residual-fuel quantity in a fuel tank. The period setting portion sets the non-detection period, based on the ambient temperature detected by the ambient-temperature detection portion and the residual-fuel quantity detected by the residual-fuel detection portion.

1. A fuel supplying controller comprising:
a fuel tank accommodating a fuel; a supply pump supplying the fuel from the fuel tank to an internal combustion engine of a vehicle; a fuel filter provided in a passage between the fuel tank and the supply pump, the fuel filter filtering the fuel; a clogging detection portion detecting a clogging of the fuel filter; a period setting portion setting a non-detection period where a clogging detection according to the clogging detection portion is prohibited; a timer count portion measuring a period from a start of the internal combustion engine to a time point that a timer counter exceeds the non-detection period; an ambient-temperature detection portion detecting an ambient temperature of an exterior of the vehicle; and a residual-fuel detection portion detecting a residual-fuel quantity in the fuel tank, wherein the period setting portion sets the non-detection period, based on the ambient temperature detected by the ambient-temperature detection portion and the residual-fuel quantity detected by the residual-fuel detection portion.
