ADAS Systems
WELDTONE is proud to support Advanced Driver Assistance systems (ADAS) with innovative technologies that enhance driver, passenger and pedestrian safety.
ADAS systems use sensors, radar, LiDar, cameras, control units and data modules to perceive surroundings, detect hazards and provide early warning signals or automated braking and steering to avoid collisions.
Statistics show many collisions occur in parking lots. Parking assist is an example of ADAS technology that is making parking easier and safer.
