Embodiment Construction

[0011] Hereinafter, a fuel supply controller according to a specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0012] figure 1 is a diagram showing the configuration of the fuel supply controller 10 according to the embodiment of the present invention. The fuel supply controller 10 according to this embodiment is an apparatus for controlling fuel supply to an engine mounted on a vehicle.

[0013] like figure 1 As shown, the fuel supply controller 10 includes an engine control electronic control unit (hereinafter will be referred to as EFI-ECU) 12 including a microcomputer as a main body. The EFI-ECU 12 is connected to an engine 14 for generating power of the vehicle. The engine 14 is equipped with a fuel pump, a fuel injector, an intake unit, an ignition unit, and the like. The engine 14 generates power by mixing and detonating fuel and air when fuel supplied from a fuel tank using a fuel pump is injected from an i...

Abstract

A fuel supply controller includes a receiver unit that receives a collision signal, which indicates that a vehicle has a collision, transmitted from an external device, an engine stop detecting unit that detects a stop of an engine mounted on the vehicle, and a fuel supply stopping unit that stops a supply of a fuel to the engine when the collision signal is received by the receiver unit and the stop of the engine is detected by the engine stop detecting unit.

Description

technical field [0001] The present invention relates to a fuel supply controller, and more particularly, to a fuel supply controller capable of appropriately stopping fuel supply to an engine when a vehicle collides. Background technique [0002] There is known a fuel supply controller that is mounted on a vehicle and stops fuel supply to the engine by stopping the fuel pump when receiving a collision signal sent when the vehicle collides (for example, refer to Japanese Patent Application Laid-Open No. 2013-071577 (JP2013 -071577A). The fuel supply controller includes an engine control electronic control unit (such as EFI-ECU), which controls the fuel supply to the engine. The engine control electronic control unit is connected to an airbag control electronic control unit (such as an airbag ECU), which Inflation of the airbag is controlled.The airbag control electronic control unit is connected to a crash sensor such as an acceleration sensor, which detects a crash of the ve...
