    • A method and system for estimating slip gain for use in the control of torque in a multi-phase induction machine. The slip gain estimate is based on a transient response of the induction machine to torque command changes. The invention is independent of machine parameters other than the slip gain. The method uses a slip gain estimation algorithm that is suited for use either as a self-calibration procedure or a background procedure that continually updates the slip gain during normal operation of the induction machine. The estimation method of the invention is suited for automotive driveline applications, which typically have limited sensor capability and which may present tuning problems associated with high volume production and with slip gain estimates when temperature changes during normal operation.
    • 用于估计多相感应电机中用于扭矩控制的滑移增益的方法和系统。 滑移增益估计是基于感应电机对转矩指令变化的瞬态响应。 本发明独立于除滑移增益之外的机器参数。 该方法使用滑移增益估计算法,其适用于在归一化机器的正常操作期间不断更新滑移增益的自校准程序或背景程序。 本发明的估计方法适用于通常具有有限的传感器能​​力的汽车传动系统应用,并且当在正常操作期间温度变化时可能产生与高体积产生相关的调谐问题以及滑移增益估计。

    • A logo device for a vehicle is disclosed. The logo device comprises a first shell including a transparent region forming a logo pattern and a nontransparent region and a second shell connected with the first shell. The first shell and the second shell form a sealed cavity therebetween. A bottom plate is disposed in the sealed cavity, and a light guide plate disposed between the bottom plate and the first shell. The light guide plate includes one or more grooves disposed thereon. A circuit board is disposed between the bottom plate and the second shell, including a plurality of illuminating elements thereon. The one or more grooves on the light guide plate receives the plurality of illuminating elements. The light guide plate is configured to direct at least a part of the light generated by the illuminating element toward the transparent region of the first shell.
