Publication number: 20110202257Abstract: In an apparatus for controlling an air/fuel ratio of a general-purpose internal combustion engine using mixed fuel containing alcohol and gasoline and operated at a desired engine speed inputted by the operator while a throttle opening is regulated such that a detected engine speed converges to the inputted desired engine speed, a fuel injection amount for mixed fuel determined based on fuel injection amount characteristics is increased/decreased when a load is kept constant and the output air/fuel ratio (at which an output of the engine becomes maximum) is estimated. And the fuel injection amount is corrected based on the estimated air/fuel ratio, thereby enabling to estimate the output air/fuel ratio without using an expensive air/fuel ratio sensor and to feedback-control the fuel injection amount such that the engine is operated at the output air/fuel ratio.Type: ApplicationFiled: December 27, 2010Publication date: August 18, 2011Applicant: HONDA MOTOR CO., LTD.Inventors: Takashi Hashizume, Tomoki Fukushima, Shigeru Saito

Patent number: 7878605Abstract: A brake apparatus for a vehicle generally sets an upper limit value of regenerative braking force to the maximum value of the regenerative braking force which can be generated at the present. In the case of a front-wheel-drive vehicle, the total braking force, the sum of front-wheel braking force (front-wheel hydraulic braking force+regenerative braking force) and rear-wheel braking force (rear-wheel hydraulic braking force), is rendered coincident with a target braking force corresponding to a brake pedal depressing force, and the regenerative braking force is set to a largest possible value equal to or less than the upper limit value. As a result, the regenerative braking force can be larger than front-wheel-side target distribution braking force. The upper limit value is decreased from the maximum value by an amount corresponding to the degree of easiness of occurrence of a locking tendency at the driven wheels (front wheels).Type: GrantFiled: July 12, 2006Date of Patent: February 1, 2011Assignee: Advics Co., Ltd.Inventors: Koichi Kokubo, Masahiro Matsuura, Shigeru Saito, Yuji Sengoku

Patent number: 7757670Abstract: A fuel supply system for a general purpose internal combustion engine is equipped with a sub-fuel tank that retains gasoline fuel supplied from a main fuel tank and houses the high-pressure pump in its interior. In other words, the pump is immersed in the gasoline fuel retained in the tank, so that if an air pocket should occur in the fuel supply pipe between the main fuel tank and pump, the air will be discharged from the sub-fuel tank to the exterior through a fuel return pipe etc., thereby ensuring that the pump does not suck in air. Since fuel injectors can therefore inject gasoline fuel immediately, starting performance is enhanced.Type: GrantFiled: August 13, 2007Date of Patent: July 20, 2010Assignee: Honda Motor Co., Ltd.Inventors: Yoshikazu Yamada, Shigeru Saito, Keiichiro Bungo, Yasunori Matsubara

Patent number: 7761214Abstract: A vehicle deceleration control device is provided that can determine an appropriate supplemental braking force when a braking force is applied according to an accelerator operation state. An engine braking-equivalent braking force is varied according to an initial accelerator angle when an accelerator returns and according to an accelerator return speed. That is, the greater the initial accelerator angle is, or the greater the accelerator return speed is, the greater the value to which the engine braking-equivalent braking force is set. It therefore becomes possible to determine the appropriate supplemental braking force that reflects the driver's braking intention.Type: GrantFiled: November 7, 2006Date of Patent: July 20, 2010Assignee: Advics Co., Ltd.Inventors: Shigeru Saito, Koichi Kokubo, Masahiro Matsuura, Yuji Sengoku

Patent number: 7657365Abstract: A fuel injection control system corrects the amount of fuel injected by fuel injection valves toward an increased side when an acceleration state resulting from operation of a throttle occurs. A control unit includes a detector, an acceleration state determinor, and an acceleration corrector. When an increase in the detected value is a predetermined value or more within a first predetermined time period, the acceleration state determiner determines that a state is an acceleration state and inputs a signal inducing fuel-amount-increase correction to the acceleration corrector. When the state where an amount of change in the detected value reaches a predetermined value or more in an increasing or decreasing direction within a first predetermined time period continuously occurs a predetermined number of times or more before a second predetermined time period expires, determination of the acceleration state is stopped until a third predetermined time period passes.Type: GrantFiled: October 24, 2008Date of Patent: February 2, 2010Assignee: Honda Motor Co., Ltd.Inventors: Tomoki Fukushima, Hayato Matsuda, Takashi Hashizume, Shigeru Saito

Patent number: 7575287Abstract: An improved vehicle brake system for controlling the frictional braking force and the regenerative braking force to be applied to a wheel of a vehicle. The brake system reduces the regenerative braking force to a predetermined force and keeps the regenerative braking force at the predetermined force before the start of anti-lock control. When the anti-lock control starts, the brake system decreases the regenerative braking force from the predetermined force. With this arrangement, it is possible to quickly eliminate a locking tendency of any wheel of the vehicle, thereby stabilizing the vehicle.Type: GrantFiled: August 22, 2006Date of Patent: August 18, 2009Assignee: Advics Co., Ltd.Inventors: Masahiro Matsuura, Koichi Kokubo, Shigeru Saito, Yuji Sengoku

Patent number: 7571967Abstract: A brake apparatus for a vehicle controls braking force acting on front wheels by hydraulic braking force (front-wheel-side vacuum-booster hydraulic pressure fraction+linear-valve differential pressure fraction), which is frictional braking force, and regenerative braking force, and controls braking force acting on rear wheels by hydraulic braking force (rear-wheel-side vacuum-booster hydraulic pressure fraction) only, to thereby perform regeneration-coordinative brake control. During performance of ABS control, the apparatus sets the limit regenerative braking force to a force under which locking of the front wheels does not occur in a case in which the force acts on the front wheels, which are wheels undergoing regenerative braking, and adjusts the regenerative braking force such that the regenerative braking force does not exceed the limit regenerative braking force.Type: GrantFiled: March 29, 2006Date of Patent: August 11, 2009Assignee: Advics Co., Ltd.Inventors: Shigeru Saito, Masahiro Matsuura, Koichi Kokubo, Yuji Sengoku
