Watch Out! and Around
To reduce the potential for unpleasant events, three areas were
optimized to give as much feedback to the driver as possible. Though we're
not allowed to use the "T" word, driving a truck is different from driving a
passenger car.
The main difference, especially for operations like parking, is
the separation of the driver from direct visual inputs. Everything is
removed from direct perception. You can't look out the back, you can't see
much on the sides, so what do you do?
Mirrors
Mirrors are the first step, though traditional, and
relatively low tech, upgrading from the default commercial truck mirrors
improves vision, particularly for driving operations on the road and in
traffic. Velvac appears to be a leading manufacturer of mirrors for
non-passenger vehicles. Follow the link below for details on mirror
selection.
Cameras
Cameras were added to improve vision. The cameras
chosen were designed for the RV market. We integrated them with a
computer-based video system rather than the basic TV monitor. The
system has three cameras one for rear vision, and one on each side to
complement the side-view mirrors. The cameras also serve as a security
system. Details on the camera/video system are available from the link
below.
Ultrasonic Sensors
Proximity, or collision avoidance, detectors are available
on some factory autos and as an aftermarket option. Typically
installed in the rear bumper and connected to an audio alarm that indicates
the presence and distance to obstructions by beeping, our vehicle has a
typical installation in the rear bumper area. A second system is
installed at the front and rear roof line to reduce the likelihood of damage
from an overhead obstruction.
