Claim:
A parking guidance system installable on large vehicles with a driver compartment, a bumper, the parking guidance system comprising a horizontal bar ( 11 ) being hollow, mounted on the bumper and having a front; at least one segment; and at least one view port on the front surface; a data collection assembly ( 10 ) being installed in the horizontal bar ( 11 ) and comprising: an assembly controller ( 20 ) having multiple inputs and multiple outputs and processing distance and video data for transmission; a memory device ( 21 ) connected to the assembly controller ( 20 ) and storing combination ultrasonic transmitter and detector module identification codes and parametric data; multiple combination ultrasonic transmitter and detector modules ( 30 ) to sense objects through the view port that the vehicle is approaching, connected respectively to inputs of the assembly controller ( 20 ) and having an ultrasonic transmitter and receiver unit ( 32 ); a signal processing circuit consisting of a microprocessor ( 31 ) connected to the ultrasonic transmitter and receiver unit ( 32 ) to control the reception of echoed signals and to the assembly controller ( 20 ) to pass digital signals to the assembly controller ( 20 ); a signal amplifier ( 33 ); and an A/D signal converter ( 34 ); and unique identification codes; a signal transmitter ( 50 ) being an RF signal transmission module, connected to the output of the assembly controller ( 20 ) and transmits RF signals; and a console unit ( 60 ) comprising a unit controller ( 61 ) having multiple inputs, multiple outputs and multiple internal preset thresholds and analyzing distance data received from the data collection unit ( 10 ) to determine whether an object the vehicle is approaching is within a threshold range and whether to initiate a warning to the driver; a memory device ( 62 ) connected to the unit controller ( 61 ) and storing all combination ultrasonic transmitter and detector module identification codes and parametric data; a signal receiver ( 65 ) being an RF signal receiver module, connected to an input of the unit controller ( 61 ), receiving RF signals from the signal transmitter ( 50 ) in the data collection assembly ( 10 ) and sending the RF signals received to the unit controller ( 61 ); an alarm ( 63 ) connected to an output of the unit controller ( 61 ) and being activated by the unit controller ( 61 ) to warn the driver when an internal preset threshold is exceeded; a monitor ( 64 ) connected to an output of the unit controller ( 61 ) and displaying images, distance data and messages; and a power supply ( 66 ) providing an operating voltage to all system components and being hardwired to the data collection assembly ( 10 ).
