Position-based limited-response mode operation in a vehicle communication system
First Claim
1. A communication system for facilitating control over a function of a vehicle, the communication system comprising:
- a base station positioned in the vehicle; and
a mobile communication unit comprising a motion sensor configured for detecting a movement of the mobile communication unit and for outputting a signal indicative of the movement;
the base station comprising a first transmitter for transmitting a signal to the mobile communication unit and a first receiver for receiving a signal from the mobile communication unit;
the base station being configured to determine a location of the mobile communication unit relative to the vehicle and to cause the mobile communication unit to operate in accordance with a limited-response mode when the location of the mobile communication unit relative to the vehicle remains substantially unchanged for a predetermined period of time, andwherein the base station is configured to cause a sensitivity of the motion sensor to be adjusted.
