Method for Power Management of Wireless Automotive Modules |
摘要 |
A satellite sensor system for a vehicle includes an application motion sensor for sensing vehicle motion for the purpose of activating a vehicle safety system, a low power consumption motion sensor for monitoring vehicle motion when the vehicle is parked or otherwise not in a driving mode, and an RF communications interface to allow the satellite sensor system to communicate with the vehicle's electronics control unit. The system withholds power from the application sensor until the low power consumption motion sensor indicates that the vehicle is about to enter a driving mode. |

1. A method of managing power in an application sensor in a vehicle, comprising:
powering a low-power MEMS sensor from a from a local energy storage device; monitoring, using the low-power MEMS sensor, at least one motion of the vehicle when the vehicle is stationary; and increasing power supply to application sensor if the low-power MEMS sensor detects at least one precursor motion. |
