The speed bump alerting system includes an ultra high frequency (UHF) radio frequency identifier (RFID) transponder disposed on a speed bump sign, and a UHF RFID reader disposed in the vehicle. The RFID reader connects to the vehicle's computer for sending speed bump data thereto. An external antenna connects to the RFID reader and is mounted to an exterior place on the vehicle. As the vehicle approaches the speed bump sign, the interrogator reads the sign mounted RFID transponder, which responds with a speed bump notification that is forwarded to the on-board computer, which posts an alert to the vehicle's display and causes the vehicle sound system to beep, thereby warning the driver to slow down for an oncoming speed bump. When the motorist slows the vehicle to an acceptable speed, the beep will stop. |
