    • A diagnostic apparatus for a vehicle can display diagnostic results and an indication of whether or not the diagnosis has been completed with a single display device. The diagnostic apparatus adapted to be mounted on the vehicle for diagnosing the vehicle based on driving condition parameters of the vehicle includes a display device or an indicator for indicating presence or absence of malfunction based on the diagnostic results, means for switching the diagnostic apparatus into a notification mode in response to a predetermined operation state, and a display control unit for displaying on the display device the indication of whether or not the diagnosis has been completed in response to being switched into the notification mode. The indication of whether or not the diagnosis has been uncompleted can be displayed on the display device by switching into a notification mode in response to the predetermined operation status. The display device may be a lamp provided near a driver's seat in the vehicle, and the indication of whether or not the diagnosis has been completed may be effected by blinking the lamp.
    • 用于车辆的诊断装置可以显示诊断结果以及用单个显示装置是否已经完成了诊断的指示。 基于车辆的驾驶状况参数,适于安装在车辆上用于诊断车辆的诊断装置包括基于诊断结果的显示装置或指示有无故障的指示器,用于将诊断装置切换为 响应于预定操作状态的通知模式;以及显示控制单元,用于响应于切换到通知模式,在显示装置上显示诊断是否已经完成的指示。 通过响应于预定的操作状态切换到通知模式,可以在显示装置上显示诊断是否未完成的指示。 显示装置可以是设置在车辆的驾驶员座椅附近的灯,并且诊断是否完成的指示可以通过使灯点亮来实现。

    • A method of controlling the air-fuel ratio of a mixture of fuel supplied to an internal combustion engine. Feedback control is effected to response to an output from an exhaust-gas concentration sensor to bring the air-fuel ratio to a predetermined value when the engine is in a predetermined medium-load operating region. It is determined whether or not the engine is in a predetermined high-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value smaller than the predetermined value, and whether or not the engine is in a predetermined low-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value larger than the predetermined value. The feedback control is effected even when the engine is in the predetermined low-load operating region, if the engine continually stayed over a first predetermined time period in the predetermined high-load operating region, and has shifted to the low-load operating region within a second predetermined time period after leaving the predetermined high-load operating region.
    • 一种控制供给内燃机的燃料混合物的空燃比的方法。 当发动机处于预定的中负荷运行区域时,进行反馈控制以响应来自排气浓度传感器的输出,以使空燃比达到预定值。 确定发动机是否处于反馈控制中断的预定高负载运行区域中,以使空燃比小于预定值,并且发动机是否处于预定的 其中反馈控制被中断以使空燃比达到大于预定值的值的低负载工作区域。 即使在发动机处于规定的低负荷运转区域的情况下,如果发动机在规定的高负荷运转区域内连续停留超过第一规定时间,也转移到低负荷工作区域内的低负荷运转区域, 在离开预定的高负载运行区域之后的第二预定时间段。

    • An idling speed feedback control method for an internal combustion engine for controlling the operating amount of a control valve for regulating the quantity of intake air being supplied to the engine in response to the difference between a desired idling speed and an actual engine speed, while the engine is in a predetermined idling region. A correction value for the operating amount of the control valve is determined in dependence upon the valve of a signal indicative of generating conditions of a generator driven by the engine for supplying electric power to at least one electrical device, and the operating amount of the control valve is corrected by means of the thus determined correction value. When the engine has entered the predetermined idling region immediately following deceleration, an initial value of the operating amount of the control valve which is applied at the start of the feedback control is set to a sum of a value obtained by correcting the correction value by means of a predetermined increment, and a predetermined reference value. While the engine is decelerating toward the predetermined idling region, the operating amount of the control valve is set to a value equal to the initial value.

    • When fully closed throttle opening learning device M1 learns a fully closed throttle opening value THMIN on the basis of an actual throttle opening value TH at an idle running time, comparison device M2 compares the sum of the fully closed throttle opening value THMIN and a predetermined value a with the actual throttle opening value TH to decide the possibility of the occurrence of a fault, and fault decision acceptance device M3 decides the acceptance/rejection of execution of the fault decision of an idle revolution controlling unit IC on the basis of the comparison result of the comparison device M2. As a result, even with a degradation in the output characteristics of a throttle opening sensor, an erroneous decision can be avoided by rejecting the execution of the fault decision when there is a possibility of an erroneous decision.
