摘要:
The present invention relates to method and apparatus for performing driving assistance for a controlled vehicle, involving determining a longitudinal acceleration target value on the basis of a lateral acceleration of the controlled vehicle and one or more setting parameters, and controlling a longitudinal acceleration of the controlled vehicle on the basis of the calculated longitudinal acceleration target value. According to the invention, a lateral acceleration acting, during cornering, on a proceeding vehicle, which moves in the longitudinal direction on the road ahead of the controlled vehicle, is estimated, and the one or more setting parameters for the calculation of the longitudinal acceleration target value are set based on the estimated lateral acceleration acting on the proceeding vehicle during cornering.

This invention relates to a motion control system and method for a vehicle. Longitudinal acceleration of the vehicle is controlled by multiplying a lateral jerk (Gy dot) of the vehicle with a prestored gain (KGyV) determined by a longitudinal velocity (V) and a lateral acceleration (Gy) of the vehicle.

The invention relates to a method that enables the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole. To provide a fuel passageway 203 as a swirling force adjustment means between the valve seat 201 and injection hole 101 of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole 101, and thus adjusts the spray shape obtained as a result.

The invention relates to using a cycling type fuel injection valve, forming a concentrated spray area and a thin spray area, adjusting the position of those, and conforming the spray to the geometric shape of engine and mounting position of the fuel injection valve so as to reduce the fuel consumption and control the unburnt component in exhaust gas. The fuel injection valve is so constructed to form a step (201,202) on the injection hole opening (101) of the fuel injection valve, to have two or more edge transition portions of the injection hole opening (101), resulting from the step (201,202), and to cause the line connecting the edge transition portions to form an oblique angle against the wall formed by the step perpendicular to the injection hole center axis (200) and the angled wall.

At an outlet portion of an injection hole (8) of a fuel injection valve (1), through removal of a part (A1, 7B) of a wall forming the injection hole (8), a restriction to a spray flow is released, thereby, a deflection spray is formed in which the spray is rich at the side of restriction released and is lean at the side of restricted, accordingly, ignition property of an internal combustion engine is improved, and an optimum spray is realized which reduces exhaust amount of unburnt gas components.

An apparatus for detecting abnormal combustion according to the present invention comprises: a unit (5, 16, 17, 19, 20) for detecting the rotation of an internal combustion engine (1); a unit (6) for calculating rotation angular acceleration on the basis of the detected rotation; a unit (7) for comparing the rotation angular acceleration with a predetermined reference value; and a unit (7) for judging whether abnormal combustion occurs. The apparatus for reducing vibration caused by abnormal combustion offsets vibration by passing a pulse-like field current in the electric generator (4) in response to detection of abnormal combustion to generate vibration torque in the electric generator.
