    摘要： A target drive shaft torque is calculated from an accelerator pedal opening degree and a vehicle speed. During acceleration of the vehicle wherein target device shaft torque is not negative, a target engine torque for generating target drive shaft torque is calculated, and a target throttle opening degree for providing target engine torque is determined. On the other hand, during deceleration of the vehicle wherein target drive shaft torque is negative, a target throttle opening degree is determined from accelerator pedal opening degree at which the drive shaft torque is zero and the throttle opening degree at which the engine torque is zero. This target throttle opening degree is in a proportional relation to the accelerator pedal opening degree and thus when accelerator pedal opening degree target throttle opening degree.

    摘要： A fuel supply amount control system for an internal combustion engine having exhaust gas recirculation passage extending between the exhaust passage and the intake passage, and an exhaust gas recirculation valve arranged across the exhaust gas recirculation passage, for recirculating part of exhaust gases emitted from the engine to the intake passage, has an ECU which detects an actual valve lift amount of the exhaust gas recirculation valve, determines a desired valve lift amount of the exhaust gas recirculation valve, based on operating conditions of the engine, and controls the exhaust gas recirculation valve, based on determined the desired valve lift amount and the detected actual valve lift amount, when the engine is in a predetermined operating region where conditions for executing exhaust gas recirculation control are satisfied. A basic fuel supply amount is calculated based on operating conditions of the engine, and a correction coefficient for correcting the basic fuel supply amount, is set based on the actual valve lift amount and the desired valve lift amount, when the engine is in the predetermined operating region. The basic fuel amount is corrected based on the correction coefficient.

    摘要： A fuel injection amount control system for an internal combustion engine includes an ECU which calculates a desired amount of fuel to be supplied to each combustion chamber in response to operating conditions of the engine, and calculates values of parameters indicative of fuel adherence characteristics of the interior of the intake passage in response to operating conditions of the engine. The ECU further calculates a first fuel amount which is directly drawn into the combustion chamber from a fuel amount injected by the fuel injection valve, and a second amount of fuel which is carried off the wall surface of the intake passage due to evaporation and drawn into the combustion chamber, based upon the values of the parameters. The ECU calculates an injection amount of fuel to be injected, by correcting the desired fuel amount, based upon the first and second fuel amounts. When the engine is in a predetermined operating condition in which convergence of the fuel injection amount calculated by the ECU to the desired fuel amount can be unstable, the value of at least one of the parameters such that the fuel injection amount stably converges to the desired fuel amount.

    摘要： A vehicle control system having program generator and convertor. The system includes a simulation device for simulating actual states such as the actual operating states of an automobile based on various input conditions, a program generation device for generating a control program for an automobile transmission or the like on the basis of the simulated states, a detection device for detecting expressions requiring quantization data included in the control program, a conversion device for converting the detected expressions using a method of notation such as reverse Polish notation, an arithmetic device for multiplying the converted variables by prescribed scaling factors obtained from the quantization factor, and for compressing the expressions multiplied by the arithmetic device. A program generated on a mainframe computer using floating point arithmetic can be translated entirely by machine into a program that can be executed by a microcomputer without using floating point arithmetic.
