PAM (PARKING AID MODULE)

The system warns the driver of obstacles located behind the vehicle during the parking manoeuvre. It
assists the driver during parking by sensing obstacles also situated outside the driver field of view. The
ECU controls the sensors, which generate a sequence of ultrasonic pulses. Upon being reflected by
an obstacle, the signal is captured by the sensor, amplified, converted into a digital signal and
transmitted in this form to the ECU. The ECU compares the signal coming in with the one given out
and determines the time elapsed between signal emission and echo reception. This value is converted
into distance and communicated to the driver in the form of audible/visible signals. The information
regarding the presence and distance of an obstacle is transmitted to the driver in the form of
acoustical signals. The acoustic signal may be pulsed with a rate depending on distance. Thus, by
combining the visual information the driver gets directly into his field of view with the audible/visible
warnings generated by the system, the driver can prevent collisions against obstacles.
