    • Disclosed is a fuel supply control device which can properly control fuel supply at any time by recovering within a short time in the event of out of phase in the drive of the step motor. In a fuel supply mechanism of an internal-combustion engine having a fuel supply control means for controlling the quantity of intake air or fuel supplied into the engine, a step motor for driving the fuel supply control means, and a control value output means for outputting control values to the step motor, the fuel supply control device comprises a position sensor for detecting the control position of the fuel supply control means, a out of phase detecting means for detecting the out of phase of the step motor from the control values supplied from the control value output means and the control position detected by the position sensor, a out of phase step value computing means for converting, into the number of steps of the step motor, a deviation between the control value and control positions at the time of detection of the out of phase condition of the step motor by the out of phase detecting means, and a control value correcting means for correcting the control values of the step motor by using the number of steps determined by the out of phase step value computing means.

    • A driving wheel slip control system installed in a vehicle and having abnormality-detecting and failsafe functions. The system includes a slip status signal-generating device for generating a slip status signal indicative of whether or not the driving wheels of the vehicle are in a predetermined slip state, and a slip level signal-generating device for generating a slip level signal indicative of a degree of slip of the driving wheels. If a logical relationship between the slip status signal and the slip level signal is abnormal, and if the prime mover for driving the driving wheels is not accelerating and at the same time the slip level signal indicates the predetermined slip state, the slip level signal is determined to be abnormal. If an abnormality is detected during driving wheel slip control, an amount of reduction in output of the driving wheels is set to a predetermined amount to thereby continue driving wheel slip control, until the prime mover enters an operating condition other than acceleration. Further, the system comprises first and second control units. The latter informs the former of three states for determining whether or not driving wheel slip control can be carried out. The first control unit has the slip level signal-generating device and the slip status signal-generating device, and inhibition of operation of these devices is retarded when it is informed of a state inhibiting driving wheel slip control, if an excessive slip state of the driving wheels is occurring.
    • 安装在车辆中的驱动轮滑移控制系统,具有异常检测和故障保护功能。 该系统包括滑动状态信号发生装置,用于产生指示车辆的驱动轮是否处于预定打滑状态的打滑状态信号,以及用于产生滑动水平信号的滑差水平信号产生装置, 驱动轮的滑动程度。 如果滑差状态信号与滑差水平信号之间的逻辑关系异常,并且如果用于驱动驱动轮的原动机不加速,同时滑差水平信号表示预定的滑动状态,滑差水平信号为 确定为异常。 如果在驱动轮打滑控制期间检测到异常,则将驱动轮的输出减少量设定为预定量,从而继续驱动车轮打滑控制,直到原动机进入加速度以外的操作条件。 此外,该系统包括第一和第二控制单元。 后者通知前三个州,以确定是否可以执行驱动轮滑差控制。 第一控制单元具有滑差信号发生装置和滑差状态信号发生装置,并且当通知禁止驱动轮打滑控制的状态时,这些装置的操作的禁止被延迟,如果 驱动轮正在发生。
