The present invention provides parking curb detection devices and methods for alerting a motor vehicle driver when a predetermined distance from a parking curb has been reached to prevent vehicle damage. An audio and/or a visible signal device alerts the vehicle driver when the correct stopping point has been reached. The present invention utilizes a triangulation led infrared sensor, a control box with digital algorithm filtering, long wave length and bandpass optical filters, and also electronic filters to largely prevent false alerts during bright sunshine conditions. |
