    摘要： A multimedia/personal computer-based system for operating information, communication, and entertainment devices in a mobile vehicle uses a power management strategy which reduces power consumption and boot-up time in a manner which facilitates use of a complex instruction set computing (CISC) processor system. A loosely coupled power management strategy utilizes a low power microprocessor off board of the main motherboard for switching a plurality of regulated voltages to the main motherboard and other devices. The use of a separate board for input/output processing and power management provides for more robust power management and facilitates adaptation of the system for inclusion in different vehicles using different input/output devices and networks.

    摘要： A multimedia/personal computer-based system for operating information, communication, and entertainment devices in a mobile vehicle uses a power management strategy which reduces power consumption and boot-up time in a manner which facilitates use of a complex instruction set computing (CISC) processor system. A power management fault strategy detects fault conditions and restores proper operation without user intervention. A low power microprocessor off-board of the main motherboard switches a plurality of regulated voltages to the main motherboard and other devices. The main application microprocessor on the main motherboard sends periodic status messages to the low power microprocessor. If a time limit between successive status messages is exceeded, then the low power microprocessor takes corrective action such as sending messages to the main application microprocessor, sending a wakeup sequence (resume event) to the main application processor, sending a reset signal to the main application microprocessor, or removing or cycling the regulated voltages being provided to the main motherboard.

    摘要： When an RDS or RBDS radio is used to listen to prerecorded media, the tuner monitors an RDS station in the background to determine when a traffic announcement is in progress. A search for selecting an appropriate station for background monitoring is provided which selects a station which is most likely to be in accordance with the individual preferences of the driver. The search method can also be used to find traffic capable stations, weather stations, emergency alert information, and news broadcasts.
