    摘要： The invention is directed to a brake light switch circuit arrangement having an additional switch S.sub.2 which opens upon actuation of the brake pedal 13 but only after a first switch S.sub.1 closes. The signals from the two switches are processed by a gating circuit (16, 17, 18) to produce brake signals (B.sub.S1 and B.sub.S2) which are to provide a standby idle-running idle-setting signal (LL*) and switch off a driving-speed controller (FGR) via the main computer (30) of the electronic diesel control. In the event that the brake switch S.sub.1 becomes defective and remains closed while overtaking another vehicle, the condition is prevented that the EDC does not reduce the injected fuel quantity to the idling quantity, even though the accelerator pedal is depressed. It is also prevented that, in the event of a fault in the brake switch (S.sub.1) while the accelerator pedal is released, constant vehicle velocity control by the EDC is not switched off.

    摘要翻译： 本发明涉及一种制动灯开关电路装置，其具有附加开关S2，该开关S2在制动踏板13致动时打开，但仅在第一开关S1闭合之后打开。 来自两个开关的信号由门控电路（16,17,18）处理，以产生制动信号（BS1和BS2），以提供备用空转运行空转设定信号（LL *）并切断驱动 - 速度控制器（FGR）通过电子柴油控制器的主计算机（30）。 在制动开关S1变为有缺陷且超车时保持关闭的情况下，即使加速踏板被压下，EDC也不会将喷射的燃料量减少到空转量。 也可以防止在油门踏板被释放时制动开关（S1）发生故障的情况下，EDC的车辆速度恒定控制不被切断。

    摘要： In a supervisory system (FIG. 7) for the accelerator pedal transducer (26) in an electronic engine control (EMS) for a vehicle engine, the output signal (U-FFG) of the transducer (26) is interpreted to show whether or not the transducer is at or close to the idling position. The resulting information is compared with the states of idling and pressure switches (18, 28) which shows whether or not the accelerator pedal (30) is actually at or close to its idling position. A contradiction resulting from this comparison indicates a fault and remedial action can be taken by the EMS, for example, to reduce the engine power to a precautionary value. A contradiction between other comparisons shows that one of the switches (18, 28) is faulty. In the event of the accelerator pedal sticking in a depressed position after the driver has lifted his foot and depressed the brake (FIG. 5) a brake signal (BS) can be passed through a gating circuit controlled by the idling switch signal (FFG-LL) to produce a reaction signal(RS). The EMS processes the latter to reduce the engine power to a precautionary safe value.

    摘要翻译： PCT No.PCT / EP89 / 01099 Sec。 371日期1991年5月21日 102（e）日期1991年5月21日PCT提交1989年9月21日PCT公布。 出版物WO91 / 04400 1991年4月4日。在用于车辆发动机的电子发动机控制（EMS）中的加速器踏板换能器（26）的监视系统（图7）中，换能器（26）的输出信号（U-FFG） ）被解释为示出换能器是否处于或接近空转位置。 将所得到的信息与空载和压力开关（18,28）的状态进行比较，其显示加速器踏板（30）是否实际上处于或接近其空转位置。 这种比较产生的矛盾表明，EMS可能会发生故障，补救措施可以采取，例如，将发动机功率降低到预防值。 其他比较之间的矛盾表明，其中一个开关（18,28）有故障。 在驾驶员抬起脚部并踩下制动器（图5）之后，当加速踏板粘在踩下位置的情况下，制动信号（BS）可以通过由空转开关信号（FFG- LL）以产生反应信号（RS）。 EMS处理后者将发动机功率降低到预防安全值。
