The PreView Side Turn Assist (STA) 79 has a wide horizontal field of view up to 180° (90° fore and 90° aft) providing side blind zone coverage along the length of the vehicle. It is designed to ignore stationary objects such as guardrails and parked cars while alerting on moving objects such as bicyclists and vehicles in the adjacent lane.

The detection Area of Interest is adjustable up to 10 meters fore, 5 meters out (3 meters for LCA) and 50 meters aft of the sensor mounting location.

Side Turn Assist Operation

At speeds of 19 mph (30 km/h) or less, the sensor prioritizes alerting the driver of VRU’s in the detection Area of Interest.  A visual alert is provided on the in-cab display when a moving object is detected while both an audible and visual alert are provided when the turn signal is active.  Stationary objects such as street signs and parked cars are ignored to minimize ‘nuisance alerts.’  This mode is optimized for use in an urban environment.

Lane Change Assist Operation

When vehicle speed is above 19 mph (30 km/h), the sensor prioritizes alerting on moving vehicles in the adjacent lane and has a smaller Area of Interest.  Stationary objects such as guardrails or concrete barriers are ignored to minimize ‘nuisance alerts.’  This mode is optimized for blind zone collision mitigation during lane changes and merging.

Milan Area B

Starting from October 1st, 2023, it will be mandatory for trucks (N3) and buses (M3) to install acoustic, visual, or tactile warning systems that alert the driver to the presence of pedestrians and cyclists in the front of the vehicle or on the sidewalk side.
Dal 1° ottobre 2024, l'obbligo di installazione dei sistemi di segnalazione sarà esteso anche ai veicoli di categoria N2 e M2.
