2 Installation Guide
2.1 Mounting the radar sensor
A mounting frame with 4xM6 threaded bushings are delivered with the sensor. An indi-
vidual concept for each car mounting situation must be developed by the car manufac-
turer. The following mounting restrictions must be fulfilled to secure a proper function of
the system.
– The radar sensor must be longitudinally and laterally leveled, aligned with the
vehicle’s longitudinal axis and mounted on the vehicle’s lateral centerline. Sensor
mounting height of 20 cm to 90 cm off the ground will ensure maximum range.
If a mounting in the vehicle centre line is not possible, the offset must be configured
via the appropriate CAN message (see chapter Configuration of the sensor position
[ } 8]).
– The sensor may be mounted flush mounted with the rear fascia.
– It is critical that the radar sensor has an unobstructed (or radar-transparent) view out
the rear of the vehicle. Optimum is a mounting without any material in front of the
sensor.
If it must be mounted behind, the plane in front of the sensor surface must be free of
conductive materials (e.g. a thin layer of vinyl, fiberglass or Kevlar).
The distance between sensor and surface depends on the used material and should
be approximately 5 mm.
