Abstract:
Methods and systems for vehicle safety lighting are disclosed, including a system having a multi-axis accelerometer that detects acceleration of the vehicle along a first axis and a second axis normal to the first axis, and outputs a corresponding first axis acceleration measurement and a second axis acceleration measurement. A controller is coupled to the multi-axis accelerometer, and to an array of light emitter elements (LELs). The controller is configured to determine a vehicle deceleration, based at least in part on a combination of the first axis acceleration measurement and second axis acceleration measurement, and to detect the vehicle deceleration exceeding a brake light threshold and, based at least in part on the detection, output a deceleration light signal to the array of LELs. Digital filtering prevents operation of the safety lighting by accelerometer outputs unrelated to axial deceleration, such as will occur upon encountering a hill, or, in the case of a motorcycle or the like, leaning into a turn.

Claim (Index 19):
A vehicle safety lighting method, comprising:\n detecting an acceleration of a vehicle along each of a plurality of axes, the axes including a first axis, a second axis that is normal to the first axis, and a third axis, the third axis being normal to the first axis and normal to the second axis, and generating a corresponding first axis acceleration measurement signal, second axis acceleration measurement, and third axis acceleration measurement signal, the first axis acceleration measurement signal, second axis acceleration measurement signal, and third axis acceleration measurement signal being continuous analog signals; receiving, at a controller, the first axis acceleration measurement signal, second axis acceleration measurement signal, and third axis acceleration measurement signal; sampling, at the controller, the first axis acceleration measurement signal, second axis acceleration measurement signal, and third axis acceleration measurement signal and outputting as a result, a respective sequence of first axis acceleration samples, sequence of second axis acceleration samples, and sequence of third axis acceleration samples; generating, at the controller, based at least in part on the sequence of first axis acceleration samples, sequence of second axis acceleration samples, and sequence of third axis acceleration samples, a sequence of filtered first axis acceleration samples, sequence of filtered second axis acceleration samples, and sequence of filtered third axis acceleration samples measurement, the filtered first axis acceleration samples being aligned with an axial direction of the vehicle, and the filtered second axis acceleration samples being aligned with a lateral axis, the lateral axis being normal to the axial direction of the vehicle; determining a vehicle deceleration, based only on the filtered first axis acceleration samples; detecting the vehicle deceleration exceeding a brake light activation threshold; based at least in part on said detecting, outputting a deceleration light signal to an array of light emitting elements (LELs); and emitting a deceleration light signal from the array of LELs in response to receiving the deceleration light signal.
