  • Mobile station having waiting process with main power off
    Patent number: 8140046
    Abstract: While main power in an automobile is off, a telematics station in the automobile intermittently runs to execute a process. The station has a first CPU in a wireless section for a wireless signal waiting process and a second CPU, having active and sleep modes, in a control section for resetting the first CPU. At resetting timing, if the first CPU is executing the process, it outputs a signal indicating that it is executing the process for the second CPU not to reset it. When the main power turns on, the second CPU determines that the signal is not outputted in order to reset the first CPU.
    Type: Grant
