3.5. Usage definition
3.5.1. System intend usage
The BSD system is designed to alert the driver with a visual indication, to the
presence of objects of interest that may be difficult to see using the inside and/or
outside rear view mirrors. This system is not designed as a substitute for the driver
to look to the side and rear of the vehicle to observe these objects. Its function is
limited to supplemental use only.
According to the section 6.1. of ISO draft norm ISO/TC204/WG14/N40.24
(Standard working draft “Lane Change Decision Aid Systems”) the rBLIS system if
from type 1, i.e.:
Type I systems provide the Blind Spot Warning function only. These systems are
intended to warn the subject vehicle driver of target vehicles in the adjacent zones.
These systems are not required to provide warnings of target vehicles which are
approaching the subject vehicle from the rear. The subject vehicle driver shall be
made aware of the limitations of this type of system, at least in the owner’s
manual. In particular, the owner’s manual shall include the following statement:
“This system provides support only within a limited area beside the vehicle. The
system may not provide adequate warning for vehicles approaching from the rear.”
3.5.2. Operating with a trailer
Because of possible field of view obstruction (tight curves or wide trailer), the BSD
system may not operate correctly. The vehicle’s owner’s manual must include a
notice stating that the system might not operate correctly when towing a trailer
which is of a type not approved by the OEM.
In addition, a trailer effectively increases the length of the host vehicle, and this
length is not supported by the BSD Sensor. If the Sensor receives a CAN
message indicating a trailer is in tow, the system shall be disabled and the BSD
status signal indicates that it is temporally off. If the trailer is a type approved by
the OEM, BSD will be disabled when the trailer is attached correctly.
