A driving assist apparatusthat performs driving assist on the basis of a traffic rule of a mobile object includes a traffic rule acquisition unit, andacquiring a traffic rule which a mobile object is highly likely to observe in an arbitrary region, and performs driving assist on the basis of the traffic rule acquired by the traffic rule acquisition unit. In particular, the driving assist apparatus includes a region acquisition unitacquiring a traffic rule deviation region where a defined traffic rule in an arbitrary region does not conform to the traffic rule acquired by the traffic rule acquisition unit, or a traffic rule correction unit correcting the traffic rule acquired by the traffic rule acquisition unit when a defined traffic rule in an arbitrary region does not conform to the traffic rule acquired by the traffic rule acquisition unit.

Driving assist apparatus

In the control system for a turbo-charged diesel aircraft engine, a target value for a fuel injection amount is determined by the stroke of a throttle lever. A boost compensator determines the maximum limit for the fuel injection amount in accordance with the boost pressure of the engine in order to suppress the formation of exhaust smoke. The actual fuel injection amount is set at the target value or the maximum limit whichever is smaller. An electronic control unit (ECU) calculates an increase rate of the stroke of the throttle lever based on an output of the stroke sensor disposed near the throttle lever. The ECU determines that the current operating condition of the aircraft requires a rapid increase in the engine output power when the increase rate of the stroke is larger than a predetermined value and increases the maximum limit determined by the boost compensator.

Control system for a turbo-charged diesel aircraft engine

In the control system for a turbo-charged diesel aircraft engine, the engine speed and the fuel injection amount are controlled by a single control lever in such a manner that the engine speed and the fuel injection amount maintain a predetermined fixed relationship in which the fuel injection amount is always smaller than a smoke limit amount. The control system further includes a boost compensator, that restricts the fuel injection amount to a value less than a boost pressure fuel limit determined by the boost pressure of the engine, and an altitude compensator that restricts the fuel injection amount to the value less than an altitude fuel limit.

The present invention is structured such that, as for travelling on the ground, there is provided a braking mechanism capable of braking wheels by the use of a single brake pedal or a braking mechanism capable of braking the wheels by flare out operation of a control stick, while automatic control of traveling direction is performed in flight using a yaw damper. In addition, a larger braking force is automatically generated, without manual operations by a pilot, for landing gear mounted on the side of an airframe toward which direction of an aircraft is to be changed as compared with the braking force applied to landing gear on the other side.

System and method for controlling traveling direction of aircraft

In the control system for a turbo-charged diesel aircraft engine, the engine speed and the fuel injection amount are controlled by a single control lever. However, when the control lever is operated to accelerate the engine, the fuel injection amount immediately increases to the value set by the control lever while the actual speed of the engine requires a relatively long time to reach the set speed. This may cause the actual fuel injection amount to become excessively larger than a value matching the engine speed and to produce exhaust smoke. In order to prevent this problem, the control system includes a delay control device which restricts the rate of increase in the fuel injection amount to a value less than a predetermined maximum value. By restricting the rate of increase in the fuel injection amount, the actual fuel injection amount is maintained at a value matching the actual engine speed during acceleration, and the generation of the exhaust smoke does not occur.

An airplane engine control method and apparatus are provided which form an engine control system easy to operate, which set a reciprocating engine of an airplane in such an operating condition in a partial power mode as to maximize the efficiency of the airframe and the engine as a whole, and which enable setting of suitable partial power in a reciprocating engine with a variable-pitch propeller in such a manner that, when predetermined partial power is set, a relationship expressed by Te &prop; &rgr;N is established with respect to the engine torque (Te), the number of engine revolutions (N) and the atmospheric density (&rgr;).

Method and apparatus for controlling airplane engine

An injection quantity control apparatus provided to an internal combustion engine having an injection nozzle which continuously injects fuel is provided. The apparatus includes a fuel quantity adjustment mechanism which has a static pressure chamber and a total pressure chamber to which a static pressure and a total pressure of an intake pipe of said engine are supplied, respectively, and adjusts an amount of fuel supplied to said injection nozzle in accordance with a dynamic pressure between a pressure of said static pressure chamber and a pressure of said total pressure chamber. The apparatus also includes a dynamic pressure corrector which corrects said dynamic pressure so that an air-fuel ratio of the engine is controlled to be substantially a target value. Thus, a desired air-fuel ratio can be achieved without a necessity of a manual operation by an operator.
