Abstract
Systems and methods are provided that include a control module of a vehicle. The control module instructs at least one of a beacon and a plurality of sensors to broadcast a ping signal in response to a user device being within a threshold distance of the vehicle. The plurality of sensors communicate signal information to the control module, and the signal information indicates an amount of reflection of the ping signal measured by the plurality of sensors. A sensor calibration module (i) determines a presence of a reflective element based on the signal information, and (ii) in response to determining the presence of the reflective element and the user device being connected to a communication gateway of the control module, adjusts a measurement of a first sensor of the plurality of sensors based on the signal information.
