The park distance control - also known as back-up warning or Parkpilot - is a useful accessory in the area of comfort electronics. Complex or closed body designs restrict sight forward and backward in many vehicles. The park distance control uses ultrasound sensors to reliably measure the distance to all kinds of obstacles, in particular to children and pedestrians. An optical and acoustic warning protects the vehicle and external objects from damage.
LEYBOLD has developed an experimental panel for the topic of park distance control, consisting of
- an original control unit
- four original ultrasound sensors, as well as
- an acoustic and
- an optical indicator.
Simulated engagement in reverse gear activates the application. When switched on, the sensors – built into the vehicle's bumper – send out ultrasound signals and receive the reflected echoes. The control unit calculates the distance of an obstacle down to the centimeter. The display shows the different distance ranges with light bars of different colors or with an acoustic distance warning with changing sound sequences.
The sensor connection cables and the ground wire to the control until are brought through bridging plugs in order to simply measure voltages and currents and simulate open circuit faults.
