Method and system for performing telematics functions using a solar powered wireless communication device

摘要

A battery-powered vehicle telematics device includes solar cells for powering the device and charging the battery. A Bluetooth® link connects the telematics device to a dongle that has been coupled to a diagnostic port of the vehicle. A USB computer connection may also provide power to the telematics device to assist the solar cells in charging the battery. The dongle and telematics devices include accelerometer components that can detect a start event and signal that the telematics device should begin operating. The accelerometers can also be used to calculate a roll angle. The telematics device can transmit a roll angle value to an active handling system or to a central server along with other vehicle information received from the dongle for further analysis and processing. A processor in the telematics device can automatically adjust and optimize the solar cell angle to maximize the capture of incident radiation.
