JBE: Junction Box Electronics
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The junction box electronics (JBE) activate the ultrasonic sensors to transmit the ultrasonic pulses. The JBE also receives the digital signals of the individual ultrasonic sensors. From the individual digital signals, the JBE control unit calculates the shortest distance between an ultrasonic sensor and the object. When an object is detected, a visual warning is given, which may also be accompanied by an acoustic warning, depending on the distance to the object.
