    • A system for automatically charging a battery of a remote keyless entry transmitter includes a voltage monitoring circuit having a first microprocessor which monitors battery voltage and which causes the transmitter to send an RF signal to a receiver in the form of a base station on a motor vehicle. The signal causes a charging circuit of the base station to activate an inductive field to cause the battery to be fully charged. In one embodiment, the first microprocessor also causes the transmitter to send a second signal to the base station to shut down the charging field when the battery voltage reaches a predetermined upper limit. In another embodiment, a second microprocessor of the base station tracks the charging time and shuts down the charging field when the charging time reaches a predetermined amount. Alternatively, charging can be done by direct contact or other means. In this way, the system not only allows for extended battery life by limiting the number of charge cycles on the battery but also allows for optimum discharge of the battery before a charging cycle begins.
    • 用于自动对远程无钥匙进入发射器的电池充电的系统包括具有第一微处理器的电压监视电路,该第一微处理器监视电池电压,并且使得发射器以机动车辆上的基站的形式向接收器发送RF信号 。 信号使基站的充电电路激活感应场,使电池充满电。 在一个实施例中,当电池电压达到预定上限时,第一微处理器还使得发射机向基站发送第二信号以关闭充电场。 在另一个实施例中,当充电时间达到预定量时,基站的第二微处理器跟踪充电时间并关闭充电场。 或者,可以通过直接接触或其他方式进行充电。 以这种方式,该系统不仅允许通过限制电池上的充电循环次数延长电池寿命,而且还允许在充电周期开始之前电池的最佳放电。

    • Load leveling height control is provided for a vehicle by replacing a conventional scheduled vehicle height with a load leveling height which is sensed upon detection of the opening of at least one compartment of the vehicle. Load leveling height control raises and lowers the vehicle to maintain the load leveling height. While either a passenger compartment or a cargo compartment can be monitored, preferably both are monitored to protect the vehicle from potential damage both below and above the vehicle due to changes in vehicle height as a vehicle is loaded and/or unloaded. Any currently active leveling activity is aborted such that a load leveling height or open compartment height can be read and maintained as long as a compartment remains open or until vehicle speed reaches a predefined speed, for example 16 kilometers per hour (10 miles per hour), at which time the conventional scheduled vehicle height is once again utilized.
    • 通过用检测到车辆的至少一个隔室的开启而检测到的负载调平高度替换传统的调度车辆高度来为车辆提供负载调平高度控制。 负载调平高度控制提高并降低车辆维持负载平整高度。 虽然可以监视乘客舱或货舱,但是优选地,两者都被监控,以保护车辆在车辆的下方和上方免受由于车辆加载和/或卸载而导致的车辆高度变化的潜在损害。 任何当前活跃的调平活动都会中止,只要舱室保持打开或车速达到预定的速度,例如每小时16公里(10英里),可以读取和维护负载平整高度或敞开舱室高度。 ,此时再次利用传统的预定车辆高度。

    • A system for selecting a user speech profile for a device in a vehicle includes a control module having a speech recognition system and a memory. The speech recognition system is configured to process audio signals and includes a speaker enrollment function configured to create a user speech profile for at least one user. The memory is configured to store a plurality of user speech profiles created by the speaker enrollment function. The system may include an external device configured to transmit a control signal to the vehicle including an identifier. Alternatively, the system may include a user input device configured to receive an input command from a user that includes an identifier. The control module uses the identifier to select a user speech profile from the plurality of user speech profiles and the speech recognition system uses the selected user speech profile to process audio signals from the user.

    • One or more vehicle suspension signals, preferably already generated within a controllable suspension system, is utilized to perform switches of the damping state of variable damping shock absorbers in the suspension system while the velocity of the shock absorbers is close to zero velocity. In particular, signals generated by height sensors within a controllable suspension system are utilized as vehicle suspension signals which are filtered to generate signals to enable switching of the shock absorbers while the shock absorbers are close to zero velocity. In addition, performance of the suspension system is improved by utilizing the vehicle suspension signals as one criterion to determine when switching from soft damping to firm damping or from firm damping to soft damping is desirable. Switch enable signals are determined from vehicle suspension signals by filtering at a resonant body frequency and comparison to an appropriate threshold. Soft-to-firm/firm-to-soft switch request signals are determined from vehicle suspension signals by filtering at a resonant wheel frequency and comparison to appropriate thresholds. Preferably, firm-to-soft switches are made after expiration of predefined time periods.
