摘要： PROBLEM TO BE SOLVED: To provide a sufficient coincidence feeling between driveability required by a driver and actual driveability following this by deciding engine torque and/or driving torque in response to a torque characteristic required by the driver by a torque control means. SOLUTION: A stroke of an accelerator pedal 1 is inputted to a driving torque control means 2 and/or an engine torque control means 3. The engine torque control means 3 and the driving torque control means 2 control respective constitutive apparatuses. Engine torque control is combined with shift control to perform driving torque control. A shift position and engine torque control, particularly, driving torque control by a combination of throttle opening can decide a vehicle speed obtained by a rotation sensor 12 and the stroke of the accelerator pedal 1. When using a high functional computer, cooperative control of an engine and a transmission can be performed by a single control means 13. A coincidence feeling of driveability can be obtained.

摘要： PROBLEM TO BE SOLVED: To scan the advancing direction of a car at a wide angle and to surely detect the position of an obstacle even at night or in fog or rain by superimposing image information obtained by an infrared sensor and distance and direction information obtained by a radar inside an electronic circuit. SOLUTION: The infrared sensor 1 photographs the images in a certain direction outside of the present car. The radar 2 emits radio waves in the direction where the infrared sensor 1 performs photographing, receives reflected waves from an object and detects a distance and the direction to the object. An obstacle detection circuit 6 superimposes the information obtained by the infrared sensor 1 and the information obtained by the radar 2 inside the electronic circuit and judges whether or not the object obtained from the radar 2 is a warm point on the images of the infrared sensor 1. Then, based on the result, whether or not the warm point is the obstacle for the traveling of the present car is judged. By combining a radar range finder and the images, the distance to all the photographed objects, the direction and a relative speed with the present car is obtained.

摘要： PROBLEM TO BE SOLVED: To detect contraflow with the minimum number of flow meters without lowering responsiveness and measuring accuracy so as to reduce fuel consumption and harmful exhaust gas components by obtaining air pressure difference between the upper and lower reaches of a flow meter in a soft way, and judging contraflow from the positive/negative relation of the air pressure difference. SOLUTION: Output of a flow meter 7 is inputted to a processor 12 and further processed by a controller 13. The flow meter 7 measures and outputs the intake air flow taken into a cylinder 1. The processor 12 obtains the cylinder charging air flow in one intake stroke from the output of the flow meter 7. The controller 13 controls an injection valve 10, a spark plug 11, and the like, and grasps contraflow by one flow meter using the time differential value of air velocity in addition to air velocity obtained from the output of the flow meter 7 and reverses the output at the time of contraflow to correct air flow. That is, the superposition of errors of two flow meters 7 is avoided so as to be able to heighten air flow measuring accuracy.

摘要： PROBLEM TO BE SOLVED: To sufficiently match a drivability demanded by a driver and a real drivability of an automobile added thereto with each other by switching a first driving torque on the basis of an intake air rate and a second driving torque on the basis of a transmission gear ratio of an automatic transmission. SOLUTION: At the time of automobile operation, a step-down rate of an acceleration pedal 1, engine speed, and automobile speed are read in, it is judged in a control device 13 whether the automobile speed is (a) and less or not, and it is judged whether the step-down rate is (A) and less or not in the case where the vehicle speed is (a) and less. In the case where the step-down rate is (A) and less, a signal is outputted to command a gear position to 4-speed, and also a driving torque target value is judged. An engine torque is found out from the step-down rate by a function in which decelerating ratio is considered, a throttle opening is found out from the engine torque and the engine speed using a throttle opening map, and a driving map demanded by a driver is outputted by a throttle controller 6. In the case where the vehicle speed is (a) or more, 2-speed, 3-speed, and 4-speed are selected according to the vehicle speed.

摘要： PROBLEM TO BE SOLVED: To control an engine with higher accuracy with its dependence suppressed on the detection accuracy of a cylinder pressure sensor and with easier precise, continuous grasp of combustion conditions. SOLUTION: The pressure P in a cylinder is detected for a symmetric phase ranging from ahead of and to behind the compression top dead center(TDC) between its compression and combustion strokes at every specified rotational angle of the crankshaft like P-n ...P-3 ...P0 ...P3 ...Pn to calculate the integral value ∫PdVcomb. of the cylinder pressures P ahead of the compression TDC and the integral value ∫PdVcomb. thereof behind the compression TDC. From their difference ∫PdVcomb. -∫PdVcomb. , the value D equivalent to the indicated mean effective pressure is thereafter calculated. The value D is then calculated for every cylinder with the value D/Qf obtained by dividing the value D by the quantity of fuel supplied Qf as its divisional value to obtain the combustion index for use in engine control. The division of the value D equivalent to the indicated mean effective pressure by the quantity of fuel supplied Qf frees the engine control from the effect of the opening angle of the throttle valve and thus deterioration in its accuracy even in a transient phase.
