1. A method comprisingidentifying, via a wireless motion detection sensor retrofit to a vehicle, a first triggering event of the wireless motion detection sensor;
- establishing, in response to the first triggering event of the wireless motion detection sensor, a threshold measurement, where the threshold measurement is based on a first status of the wireless detection sensor and the first status of the wireless detection sensor relates to a characteristic of the wireless detection sensor over a period of time;
establishing, in response to a second triggering event of the wireless motion detection sensor, a detection measurement, where the detection measurement is based on a second status of the wireless detection sensor, wherein one or more of establishing the threshold measurement or establishing the detection measurement comprises filtering a measurement of the wireless motion detection sensor for false trigger events based at least on at least a speed differential of the vehicle and a false trigger object associated with the false trigger event;
generating, by comparing the detection measurement to the threshold measurement, a detection identifier for indicating presence of a trigger object in an area surrounding a vehicle; and
transmitting, using a wireless transmission protocol and to a receiver device spaced from the wireless motion detection sensor, an indication signal, based at least in part on the detection identifier, wherein the receiver device comprises an indicator configured to notify, based on the indication signal, a user of the presence of the trigger object in the area surrounding the vehicle.

Abstract
A method and system for detecting an object in the “blind-spot” of a moving vehicle. The system can be user-installed to retrofit a vehicle, e.g., one that lacks a more complex, factory-installed blind-spot detection system. The invention thus provides an inexpensive and simplified vehicle safety enhancement.
