Abstract

The present invention discloses methods and systems for communicating between a vehicle and a remote device. The methods, apparatus, and the systems are provided for communications between a vehicle and a remote device using a first vehicle communications module that communicates via a first communication channel. One exemplary method involves transmitting, by a second vehicle communications module via a second communication channel, an indication of an operating state of the first communications module, receiving, by the first communications module via the first communication channel, an acknowledgment responsive to the indication from the remote device, and changing the operating state of the first communications module in response to receiving the acknowledgment.

Description

technical field [0001] Embodiments of the subject matter described herein relate generally to vehicle systems, and more particularly, to systems and methods for communicating between a vehicle and a remote device, such as an electronic key fob. Background technique [0002] In recent years, advances in technology have caused substantial changes in the design of automobiles. For example, electronic key fobs are now ubiquitous and can communicate with the vehicle to allow the user to initiate any number of operations, such as remote start, remote lock / unlock or the like. More recently, fob-based automation is being incorporated into vehicles. However, these so-called "passive" features typically require the vehicle to continuously monitor the surrounding environment for the presence of the key fob, which in turn continuously drains power from the battery or another energy source within the vehicle. Multiple communication modules can be co-located and integrated within a sing...
