    • A luminescent powder (1) with luminescent particles (2) having an average luminescent-particle size (3) selected from the range of from 0.1 μm inclusive to 5.0 μm inclusive. The luminescent particles comprise primary particles (4) having an average primary-particle size (5) selected from the range of from 0.1 μm inclusive to 1.0 μm inclusive. The primary particles which, for example, consist of a cerium-doped yttrium-aluminum garnet (Y3Al5O12), are agglomerated to form the luminescent particles. A method for producing the luminescent powder has the following steps: a) preparing at least one precursor of the primary particles, b) producing the primary particles from the precursor of the primary particles, and c) forming the luminescent particles of the luminescent powder from the primary particles. The precursor for Y3Al5O12 is, for example, a powder mixture of hydroxides. In order to prepare the precursor, the hydroxides are precipitated from a sulfuric-acid solution containing metal by dropwise addition of a basic ammonia solution. The precipitate is dried and subsequently calcined, so that the primary particles are formed and simultaneously cluster together to form the luminescent particles of the luminescent powder.
    • 具有平均发光粒径(3)的发光粒子(2)的发光粉末(1)选自0.1μm以上且5.0μm以下的范围。 发光粒子包含平均一次粒径(5)的一次粒子(4),其选自包括0.1〜1.0μm的范围的0.1μm以上1.0μm以下的范围。 例如由铈掺杂的钇铝石榴石(Y3Al5O12)组成的初级颗粒被聚集以形成发光颗粒。 一种发光粉末的制造方法,其特征在于,具备以下工序:a)制备所述一次粒子的至少一种前体,b)从所述一次粒子的前体制备所述一次粒子,c)从所述一次粒子的前体形成发光粒子, 初级粒子。 Y 3 Al 5 O 12的前体是例如氢氧化物的粉末混合物。 为了制备前体,通过滴加碱性氨溶液使氢氧化物从含有金属的硫酸溶液中沉淀。 将沉淀物干燥并随后煅烧,使得初级颗粒形成并同时聚集在一起以形成发光粉末的发光颗粒。

    • A method for monitoring a subsystem installed in a motor vehicle involves a diagnostic unit checking the subsystem for system errors at least during driving cycles of the motor vehicle, the check being carried out for an occurrence as well as for a correction of a system error. The diagnostic unit carries out a misuse assessment based on a frequency of detection of the occurrence and/or the correction of the system error in order to determine whether the detected occurrence and/or the detected correction of the system error is/are based on misuse. If occurrence of the system error is detected, a restricted operating mode is activated or an activated restricted operating mode is continued in which drivability of the vehicle is restricted after a predefinable number of driving cycles has elapsed or after a predefinable travel distance has passed without the correction of the system error being detected.
    • 一种用于监测安装在机动车辆中的子系统的方法包括至少在机动车辆的驾驶循环期间对诊断单元检查系统错误的系统错误,该检查是为了出现以及用于校正系统错误而进行的。 诊断单元基于发生的检测频率和/或系统错误的校正来进行误用评估,以便确定检测到的发生和/或检测到的系统错误的校正是否基于误用 。 如果检测到发生系统错误,则在经过预定数量的驾驶循环之后或经过可预定的行驶距离之后,或者经过可预定的行驶距离之后,激活限制的操作模式或继续启动受限制的操作模式,其中车辆的驾驶性能受到限制 正在检测到系统错误的校正。
