摘要:
PROBLEM TO BE SOLVED: To stably and positively supply fuel to an internal combustion engine even during high-speed turning of a vehicle in the case the internal combustion engine having a single or a plurality of fuel pumps are mounted on the vehicle.SOLUTION: The fuel supply control device includes a fuel tank 14 for storing fuel supplied to an engine 12, a first fuel pump P1 for press-feeding the fuel, a sub tank 16 for storing the first fuel pump P1, a second fuel pump P2 for transferring the fuel in the fuel tank 14 to the sub tank 16 via a fuel return passage 38, a fuel amount detecting means 44 for detecting an amount of remaining fuel in the fuel tank 14, and a lateral acceleration sensor S1 and a longitudinal acceleration sensor S2 for estimating the inclination of the fuel liquid level. The second fuel pump P2 is driven and controlled based on the remaining fuel amount and a fuel liquid level inclination angle θ.
