PDC Control Unit
The PDC control unit controls the ultrasonic sensors for transmitting ultrasonic impulses. The PDC control unit also receives the digital signals from the individual ultrasonic sensors. By comparing the individual digital signals, the PDC control unit calculates the minimum distance between the ultrasonic sensor and the object.
When an object is detected, an acoustic warning and a visual warning are given.
The PDC control unit is connected to the following control units via the bus systems:
