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 cruise control system for maintaining the speed of a vehicle at a fixed, set speed, comprising an actuator including an electric motor which actuates a speed control member via an electromagnetic clutch. To ensure the capability of the cruise control system to decelerate the vehicle even when it is traveling a steep and long downhill, and the normal operation of the cruise control system becomes inadequate for curbing the excessive increase of the vehicle speed, the electromagnetic clutch is disengaged whereby the speed control member is returned to the position for maximum deceleration. Since the operation of the cruise control system is not canceled even when the vehicle speed is increased substantially beyond the set speed, the cruise control system can readily return to its normal operation even after the vehicle is accelerated from the state of cruise control by stepping on the accelerator pedal, for instance for passing another car. To avoid frequent activation of the electromagnetic clutch, there may be defined an intermediate speed range in which a boosted deceleration signal is supplied to the electric motor for a deceleration action which is more boosted than a normal deceleration signal.
摘要翻译：一种用于将车辆的速度保持在固定的设定速度的巡航控制系统，包括具有通过电磁离合器致动速度控制部件的电动机的致动器。为了确保巡航控制系统即使在行驶陡峭和长时间下坡时减速的能力，并且巡航控制系统的正常操作变得不足以抑制车辆速度的过度增加，电磁离合器被分离由此，速度控制部件返回到最大减速的位置。由于巡航控制系统的操作即使在车速大幅提高到设定速度的情况下也不会消除，所以即使在车辆从巡航控制状态加速后，巡航控制系统也可以容易地恢复正常运行加速踏板，例如通过另一辆车。为了避免频繁地启动电磁离合器，可以限定一个中间速度范围，其中增压减速信号被提供给电动机用于比正常减速信号更加升高的减速动作。

摘要： An apparatus for sensing the concentration of oxygen in a gas such as engine exhaust gas includes an oxygen concentration sensor formed of an oxygen pump element and a sensor cell element, each based on a solid electrolytic member formed of a material such as ZrO.sub.2, and is provided with a limiter circuit which functions to reduce the level of current supplied to the oxygen pump element when a voltage produced by the sensor cell element indicates that this current level is such as to produce a "blackening" phenomenon whereby deterioration of the oxygen pump element will occur and oxygen concentration sensing reliability will be lowered. The apparatus also includes a delay circuit which functions such that a reduction of the oxygen pump element current level is delayed by a predetermined time interval, after an increase of the sensor cell element voltage to the "blanking" region is detected, thereby preventing fluctuations in the oxygen pump element current level due to transient increases in sensor cell element voltage and increasing the sensing reliability.

摘要： An air intake side secondary air supply system for an internal combustion engine having an air intake side secondary air supply system includes an oxygen concentration sensor, and controls a duty ratio of opening and closing of an open/close valve disposed in the air intake side secondary air supply passage by determining a valve open period within each duty cycle of control operation in accordance with a result of comparison between the level of the output signal of the oxygen concentration sensor and a level corresponding to a target air-fuel ratio. The duty ratio of opening and closing of the open/close valve is maintained within a predetermined duty ratio range so as to improve effectiveness of the control of the secondary air supply as well as to avoid the generation of over lean or over rich mixture.

摘要： A vacuum-operated actuator controls opening and closing of a throttle valve in an intake passage of an internal combustion engine in response to pressure in a vacuum chamber thereof. A change-over control valve supplies the vacuum chamber, selectively, with first and second control pressures for opening and closing the throttle valve, respectively. An electronic control unit controls the engine idling rotational speed by generating an on-off control pulse signal having a period corresponding to the engine rotational speed, and supplying the change-over control valve with the on-off control pulse signal to cause same to supply the vacuum chamber with the first or second control pressure. The electronic control unit determines the engine rotational speed and a rate of decrease in the engine rotational speed, and halts the idling speed control for a predetermined period of time when the determined engine rotational speed falls within a predetermined range and at the same time the determined rate of decrease falls within a predetermined range. A valve opening-correcting device corrects the throttle valve opening to a larger opening in response to at least one predetermined external load applied on the engine. The electronic control unit actuates the valve opening-correcting device to increase the throttle valve opening which is determined by the change-over control valve in response to the on-off control pulse signal.
