The system uses a digital camera incorporated into both door mirrors that monitors the area alongside the car for other automobiles. The driver is alerted by an orange light housed in the car's A-pillar by the door mirror. BLIS also works after dark, when it will react to the headlamps of any surrounding vehicles.
Volvo says the BLIS system does not relieve the driver of their obligation and responsibility to do the usual visual checks before attempting any manoeuvring. It does afford frequent motorway users or city drivers an added level of protection against vehicles out of the driver’s field of vision.
Volvo says BLIS is capable of making the distinction between mobile and static objects such as parked cars, road barriers, lampposts and other static objects, ensuring all alerts are limited to potentially hazardous moving obstacles.
BLIS is available as an option on the XC90 and is expected to be introduced to the rest of the Volvo range next year.
