Abstract:
1. A control method for controlling power functions within a vehicle telematics control unit comprising: accessing stored voltage information for a battery included in a vehicle; determining a present voltage characteristic of the battery based on measurements of voltage; determining whether a difference exists between the stored voltage information and the present voltage characteristic; converting an operational state of a vehicle telematics control unit responsive to determining that a difference exists; accessing threshold information associated with the battery; comparing the present voltage characteristic of the battery to the threshold information; determining whether the present voltage characteristic of the battery satisfies a threshold requirement indicated by the threshold information; and generating a first control signal responsive to determining that the present voltage characteristic of the battery satisfies the threshold requirement indicated by the threshold information, wherein the generating of the first control signal comprises: accessing stored information including a preset first time determining whether the present voltage characteristic of the battery is kept higher than a threshold voltage indicated by the threshold information for the preset first time and generating the first control signal in response to determining that the present voltage characteristic of the battery is kept higher than the threshold voltage for the preset first time.
