    • A troubleshooting apparatus counts the number of times an abnormality occurs whenever each diagnosed portion of an automobile air-conditioning system repeats an abnormal and a normal status, stores each diagnosed portion in which an abnormality is detected and the number of times the abnormality of each diagnosed portion occurs in a nonvolatile memory, recognizes each diagnosed portion having the number of times the abnormality exceeds a predetermined value at the time of troubleshooting as a fault, and recognizes each diagnosed portion having an abnormality that occurs at the time of troubleshooting as a fault. Abnormalities that occur in conjunction with the dismounting and remounting of diagnosed portions during checking processes are absorbed in the number of times the abnormality occurs within the predetermined value so that a wrong diagnosis can be avoided. Moreover, each diagnosed portion having the number of times the abnormality exceeds the predetermined value and each diagnosed portion having an abnormality that occurs during the diagnostic process can be distinguished from each other. Consequently, check and repairs can be based on an understanding of whether or not the abnormality lacks repeatability such as an imperfect contact and a half-disconnection.
    • 故障排除装置计算当汽车空调系统的每个诊断部分重复异常和正常状态时异常发生的次数,存储检测到异常的每个诊断部分和每个被诊断的异常的次数 部分发生在非易失性存储器中,在故障排除时识别具有异常超过预定值的次数的每个诊断部分作为故障,并且识别出故障时出现的具有异常的诊断部分。 在检查过程中与诊断部分的拆卸和重新安装一起发生的异常被吸收在预定值内发生异常的次数,从而可以避免错误的诊断。 此外,具有异常次数超过预定值的每个诊断部分,并且可以将在诊断过程中发生的具有异常的每个诊断部分彼此区分开。 因此,检查和修理可以基于对异常是否缺少诸如不良接触和半断开之类的重复性的理解。

    • An air conditioning control system for an automotive vehicle having an internal combustion engine. A variable capacity compressor has a pump having displacement thereof variable in response to a change in pressure within a controlled pressure chamber, a communication passage communicating between a low pressure chamber and the controlled pressure chamber, and a valve disposed to vary an opening area of the communication passage. An electromagnetic clutch connects and disconnects the compressor to and from the engine. An evaporator is connected to the compressor. A control unit controls the capacity of the compressor by supplying the valve with control current normally set within a predetermined range, to vary the opening area of the communication passage such that the temperature of outlet air from the evaporator becomes equal to a desired value. The control unit supplies the control current having a predetermined value larger than the above predetermined range over a predetermined time period to control the capacity of the compressor to the minimum value, when the electromagnetic clutch is brought into an engaged state from a disengaged state.
    • 一种用于具有内燃机的机动车辆的空调控制系统。 可变容量压缩机具有响应于受控压力室内的压力变化而变化的排量的泵,在低压室和受控压力室之间连通的连通通道以及设置成改变所述压力室的开口面积的阀 沟通通道。 电磁离合器将压缩机与发动机连接并断开。 蒸发器连接到压缩机。 控制单元通过向阀提供通常设定在预定范围内的控制电流来控制压缩机的容量,以改变连通通道的开口面积,使得来自蒸发器的出口空气的温度等于期望值。 当电磁离合器从脱离状态进入接合状态时,控制单元在预定时间段内提供具有大于上述预定范围的预定值的控制电流,以将压缩机的容量控制在最小值。

    • An automotive air-conditioning system includes an arithmetic unit which provides combined control signals at least on the basis of data representing room temperature, fresh air temperature, set temperature and intensity of insolation; a blower control unit which controls the blowing rate of a blower according to the combined signals; an air mixing control unit which controls the opening of an air mixing door on the basis of the combined signals; a mode changing unit which establishes the defrosting mode, the face mode, the foot mode or the bilevel mode according to a mode changing signal based on the opening of the air mixing door and the temperature of an evaporator; a blowing rate control unit which increases the actual blowing rate of the blower gradually after the actuation of the blower; and a control unit which controls the air mixing door control unit and the mode changing unit on the basis of the temperature of the engine cooling water. The foot mode where conditioned air is blown through the foot opening is established while the blowing rate of the blower is being increased to a blowing rate corresponding to the combined signals after the actuation of the blower, and movement of the air mixing door beyond a predetermined position toward a position for a cooling mode is inhibited when the temperature of the engine cooling water is on the high level, so that agreeable air-conditioning is achieved without being affected adversely by the intensity of insolation.
