摘要： An air-fuel ratio control system for an internal combustion engine, including an oxygen concentration sensor producing an output signal whose level is substantially proportional to an oxygen concentration of the exhaust gas, effects a feedback control of the air-fuel ratio of mixture to be supplied to the engine toward a target value determined on the basis of various parameters of the engine operation and corrected in response to a magnitude of atmospheric pressure, so that the target air-fuel ratio is made lean as the magnitude of the atmospheric pressure decreases. Thus, the reduction of the engine output power and the increase of the fuel comsumption which have been encountered in conventional systems are prevented.

摘要： An air/fuel ratio control system for an internal combustion engine provides a mixture leaner than a predetermined reference value when a detected engine load is in a light load range. In order to produce a required engine power during a transitional period, the system detects the speed of variation of an operating parameter used for the calculation of air/fuel ratio and controls the air/fuel ratio toward the reference level even though the magnitude of the detected engine load is in the light load range. Preferably, an EGR rate is also made smaller upon occurrence of a rapid change of the operating parameter so as to prevent the power down of the engine during the transitional period.

摘要： A headlight is turned on if an external illuminance value outside of the vehicle is equal to or lower than a first threshold value if the non-rainfall state is judged from windshield wiper activation, and is permitted to be turned on if the external illuminance value is equal to or lower than a second threshold value higher than the first predetermined illuminance value if the rainfall state is judged. When the vehicle is capable of being driven and the headlight is turned on, if an average illuminance value of the external illuminance value is equal to or higher than a predetermined value, then the second threshold value switches to the first threshold value. When the headlight is turned off, if the activation of the wiper has not been confirmed for a first predetermined period, then the second threshold value switches to the first threshold value.

摘要： A vehicle cruise control system having an electric actuator for acting upon a throttle valve of a vehicle, a clutch for disconnecting the actuator from the throttle valve, a spring or the like for returning the output end of the clutch to a neutral state and a limit switch for detecting the limit of the motion of the output end of the clutch and discontinuing the supply of electric current to the actuator upon detection of the limit. Since the detection of the lower limit of the stroke of the actuator for decelerating the vehicle is necessary for preventing unnecessary supply of electric current to the actuator and overloading of the actuator, the closed state of the limit switch is tested by supplying an electric current to the actuator so as to decelerate the vehicle prior to starting the normal operation of the vehicle cruise control and determining if the electric current is indeed conducted through the actuator or not.

摘要： A method of detecting abnormality in an air-fuel ratio control system for an internal combustion engine, the air-fuel ratio control system having a proportional control valve arranged in an air supply passage for supplying secondary air therethrough to the engine and controlled in response to an output signal from an oxygen concentration sensor arranged in an exhaust system of the engine in a manner such that its valve opening varies in proportion to the magnitude of driving current supplied thereto. A circuit is provided which includes a first transistor, the proportional control valve, and a second transistor arranged in the order mentioned and serially connected with each other between a power source for supplying a predetermined voltage and ground. A value of voltage at a predetermined location in said circuit is sensed while the first and second transistors are in predetermined states of conduction and non-conduction. It is determined whether there is abnormality in the air-fuel ratio control system, on the basis of the sensed voltage value.

摘要： A counter increases a counted value at regular time intervals during a transmission time of a request signal Sr transmitted based on trigger signals input from a door unlocking sensor or the like. On the other hand, the counter decreases the counted value at regular time intervals during a non-transmission time of the request signal Sr. A determination unit either prohibits or permits transmission of the request signal Sr to a portable unit, based on comparison results of the counted value with a prohibition value and a lifting value.

摘要： A method of indicating when a shift operation of a manual gearbox is to be preformed includes a step for comparing a detected vehicle speed with a reference vehicle speed which is determined and changed on the basis of a detected engine operational parameter and a step for indicating that the shift operation should be performed on the basis of a result of the comparison. The reference vehicle speed is corrected to a lower speed in response to an increase of a total running time of the vehicle, thereby to maintain the driveability of the vehicle when the running time of the vehicle is short.
