Embodiment Construction

[0078] The following detailed description is merely exemplary in nature and not intended to limit application and use. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0079] The subject matter presented herein relates to methods and apparatus for optimizing battery life in a remote device in communication with a PEPS system associated with a vehicle. In some embodiments, the remote device periodically utilizes a "sleep mode" (ie, a low power mode), a state in which the remote device's internal circuits are largely turned off. When the remote device determines that it is within the authorized signal range of the vehicle and is approaching the vehicle, internal circuitry of the remote device is activated.

[0080] Vehicles can be, but are not limited to, any of a number of different types: automobiles (cars, trucks, motorcycles, sport ...

Abstract

A method for activating a remote device is provided. In response to a determination that a remote device is within a first mode signal range of a vehicle and the remote device is moving, the method activates a second mode communication module of the remote device.

Description

technical field [0001] The subject matter presented herein relates generally to vehicles, and more specifically to passive entry, keyless start (PEPS) systems, and conserving battery life of remote devices connected to PEPS systems. Background technique [0002] The keyless entry system allows the driver or anyone with an authorized remote device, such as a key fob, to unlock the doors of the vehicle when they are in close proximity to the vehicle without touching the remote device. Once the remote device is within range of the vehicle, the locked door can be opened by pulling the door handle. Additionally, some keyless entry and start (PEPS) systems may be configured to automatically start a vehicle's engine when an authorized remote device is in proximity to the vehicle. Other PEPS systems require the driver to push an ignition button to start and / or stop the vehicle's engine. [0003] The problem with the existing PEPS functionality is that the authorized remote device ...
