摘要： A shifting mechanism includes a limit switch that sends an open-close signal of the switch contacts SW1, SW2, SW3 and SW4 out to a control mechanism according to a 2H-4H-N-4L shifting sequence. The switch contacts SW1 and SW2 detect the position of a slider 4H which is moved by a thrust actuator, during shifting in the range of 4H engagement to the range of N engagement. Therefore, if one of the switch contacts SW1 and SW2 is faulty, the other switch detects shifting between 4H and N. This prevents shifting into N over 4H, thereby preventing malfunction of the thrust actuator resulting from a faulty switch contact SW1 or SW2. This also avoids potential difficulties in vehicle control due to shifting characteristics and permits the maintaining of controlled driving.
摘要翻译： 换档机构包括根据2H-4H-N-4L换档顺序将开关触点SW1，SW2，SW3和SW4的开 - 关信号发送到控制机构的限位开关。 开关触点SW1和SW2在4H接合范围内移动到N接合范围内时，检测由推力致动器移动的滑块4H的位置。 因此，如果开关触点SW1和SW2中的一个发生故障，则另一个开关检测4H和N之间的移动。这防止了在4H之间移动到N中，从而防止由于故障的开关触点SW1或SW2引起的推力致动器的故障。 这也避免了由于移动特性而导致的车辆控制中的潜在困难，并允许维持受控驾驶。

摘要： First, second, and third electrodes are exposed to a fuel passage. The third electrode defines a first gap with the first electrode and defines a second gap with the second electrode. A property detection unit detects a property of fuel according to a summation of a first capacitance of the first gap and a second capacitance of the second gap. A correct-erroneous determination unit determines whether the property detected with the property detection unit is correct or erroneous according to a ratio of the summation and the first capacitance.

摘要： A capacitance sensing section senses a capacitance between first and second electrodes. A temperature sensing section senses fuel temperature. A microcomputer functions as a concentration sensing section and senses a concentration of ethanol contained in fuel based on the capacitance sensed by the capacitance sensing section and the temperature sensed by the temperature sensing section. The microcomputer functions as an abnormality detecting section and performs abnormality determination to determine that an abnormality has occurred in the capacitance sensing section when the capacitance sensed by the capacitance sensing section does not change and the temperature sensed by the temperature sensing section changes. Since a dielectric constant has such a temperature characteristic that the dielectric constant changes with the temperature, the abnormality detecting section can detect occurrence of the abnormality in the capacitance sensing section.

摘要： A liquid property detecting device includes a switch portion switching an electrode to charge with a standard voltage generated by a generator, or discharge through a grounding. An operation signal output portion outputs an operation signal to the switch portion so as to switch in a predetermined switch period. A voltage of the electrode is output as a detection signal, when the standard voltage is applied to the electrode. A signal process portion calculates liquid property based on the detection signals. A gain of the signal process portion relative to the detection signal is increased, as the detection signal is decreased.

摘要： A microcomputer of an alcohol concentration sensor reads a first measurement value corresponding to a first frequency and reads a second measurement value corresponding to a second frequency. The microcomputer calculates a difference between the first and second measurement values. The microcomputer performs stuck failure abnormality determination when a state where the difference between the measurement values is equal to or smaller than a predetermined value continues. The microcomputer outputs a PWM signal of a specific frequency, which is different from a frequency in a case of a normality, to an engine ECU. Thus, a failure of the alcohol concentration sensor can be surely determined.
