Blind Spot Assist
Blind Spot Assist monitors the area which the driver is unable to take in via the mirrors, indicates in the exterior mirror when vehicles are located in this zone and additionally sounds an acoustic warning when the driver activates the indicator.
Dangerous situations frequently arise because a driver fails to respond or responds too late to other road users who are hidden in his vehicle's blind spot.
The blind spot is the area which a driver is unable to take in using the rear-view and exterior mirrors. Blind Spot Assist monitors precisely this source of danger. It employs close-range radar sensors to detect vehicles in this hidden area in good time.
When the system detects another vehicle, this is indicated to the driver by a red warning triangle which lights up in the relevant exterior mirror. An acoustic warning will additionally sound if the indicator is activated despite the visual warning.
Blind Spot Assist operates in a speed range from 30 to 250 km/h. The warning area extends approx. 3.5 m to either side of the vehicle and 3 m beyond the rear end. Detected vehicles which are overtaking are indicated immediately after entering the monitoring zone when the relative speed difference between the vehicles does not exceed 16 km/h.
Vehicles which have just been overtaken are indicated following a delay of 1.5 seconds after entering the monitored zone. This avoids disturbing, unintended warnings.
While Blind Spot Assist is no substitute for foresighted driving, it can help to offset driver errors.
