摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to highly precisely estimate the gradient of a road surface on which a vehicle is traveling based on a differential value ACCw of the traveling speed (actual speed V) of a vehicle and a detection value ACCg of an accelerator sensor for sensing acceleration based on a force added thereto. SOLUTION: A first estimated value ACCrg is calculated as a difference between a differential value ACCw and a detected value ACCg, and prescribed correction is applied thereto so that a second estimated value ACCrgp can be calculated. The second estimated value ACCrgp is filtered by a low pass filter B48 so that a gradient estimated value AGGrgf can be calculated. A gradient change estimated value Δ is calculated based on a difference between the first estimated value AGGrg and a delay estimated value ACCrgL filtered by a low pass filter B50. A cutoff frequency fc of a low pass filter B48 is variably set according to the gradient change estimated value Δ. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To smoothly avoid the collision of a vehicle with an obstacle in the case of stopping the vehicle in a short distance, for example, in driving the vehicle in reverse.
SOLUTION: The system 1 for avoiding the collision of the vehicle with the obstacle is mounted on the vehicle 2, and comprises a control unit 3, an acoustic wave sonar 4, a steering sensor 5, a display device 6, and a brake control section 7. The acoustic wave sonar 4 can detect the existence of the obstacle within the range behind the vehicle 2, and can detect the distance from the vehicle to the obstacle. The control unit 3 predicts the course of the vehicle 2 based on the detected signal of a steering angle output from the steering sensor 5, and judges the risk of the collision of the own vehicle 2 with the obstacle based on the distance from the vehicle to the obstacle and the predicted course, and sets the vehicle speed according to the risk, and further carries out the brake control so as to achieve the set vehicle speed.

摘要： PROBLEM TO BE SOLVED: To reduce a seating shock by dropping the seating speed of a valve member while quickening the motion of the valve member at the valve closing time and reduce the operation sound at the seating time as well. SOLUTION: This nozzle needle 20 is energized toward a valve seat by the energizing force of a spring and a contact part 21 can be seated on the valve seat 16a. A slide part 22 formed on the fuel upper streamside of the contact part 21 is supported on the inner wall of a valve body 15 reciprocatably. A flange 24 formed in a flat annular shape between the contact part 21 and slide part 22 receives a force from the upper streamside of the flange 24 to the valve close direction by the fuel flowing to the lower streamside. The flow passage area of an annular clearance 60 formed between the flange 24 and the inner wall of the valve body 15 is set so as to become larger than the opening area formed between the contact part 21 and valve seat 16a when the nozzle needle 20 is lifted maximumly.

摘要： PROBLEM TO BE SOLVED: To provide an electronic control type fuel injection device for an internal combustion engine to prevent leakage between a fuel injection valve and a fuel distribution piping, improve the assembling ability of an engine, and suppress the generation of working noise of the injection valve to a low value. SOLUTION: A mounting hole 24 through which a fuel injection valve 5 is mounted vertically to a fuel passage 23 in a fuel distribution piping, and the housing yoke 25 of a fuel injection valve 5 to contain an electromagnetic coil being a working noise generating source is inserted in the mounting hole 24. Since the fuel injection valve 5 and a fuel distribution piping are integrally coupled together, a leakage of fuel through a fuel passage 23 does not occur and a space in an engine is ensured, whereby, the assembling ability of the engine is improved. Further, since an injection nozzle hole position is situated in the vicinity of the intake valve of the engine, an amount of fuel wet in an intake pipe is reduced, and the power performance of an engine is improved. Further, since an electromagnetic coil is located in the fuel distribution pipe, working noise is not propagated to the outside.

摘要： PROBLEM TO BE SOLVED: To suppress defective injection of fuel by a method wherein a fuel passage is extended in an antigravity direction as it is separated away from the axis of a coil of which a solenoid part consists, and communicated with the external space of a valve housing. SOLUTION: A fuel injection valve 20 comprises a solenoid part to generate an electromagnetic attraction force and a valve. Fuel passages 31a communicated with an annular passage 34 are formed in a plurality of spots on the large part of a guide part 31 of which the valve part consists. The fuel passage 31a is extended in the direction of an antiweight in the radial direction based on the axis of the guide part 31 as it is separated away from the axis of a coil 25 of which a solenoid part consists, and a fuel feed groove 30 and an annular passage 34 are intercommunicated through a short distance. This constitution suppresses defective injection of fuel since vapor generated due to dead leak is discharged to the outside of a fuel injection valve 20, and ensures fuel injection precision even during high temperature restarting.
