The radar system uses a bumper mounted radar unit in conjunction with a Video Radar Decision Unit (VRDU in current, VRDU2 in new Cascadia) in order to monitor objects ahead of the vehicle and commands the ABS, transmission and other engine functions in the truck in case of need.
DETECTING POTENTIAL COLLISIONS BEFORE THEY HAPPEN
In the original Freightliner Cascadia®, Active Brake Assist 2.0 (ABA 2.0) is always on, detecting distances to objects, calculating speed and determining whether warnings or actions are necessary. Based on the position and speed of the truck in relation to other vehicles, ABA 2.0 warns the driver and can engage in full or partial braking to mitigate potential collisions that might otherwise be unavoidable.
When a moving pedestrian enters the truck’s path, Active Brake Assist 5.0 applies input from the radar and camera sensors to warn the driver with visual and audible alerts and applies partial braking. If the driver doesn’t take action, full emergency braking brings the truck to a complete stop, provided the pedestrian is moving.
On the original Freightliner Cascadia®, Adaptive Cruise Control (ACC) automatically adjusts cruising speed to maintain a safe, continuous following distance of 3.5 seconds from vehicles in its lane ahead. With the optional headway switch, following distance can be adjusted between 3.5 and 2.3 seconds. ACC decelerates the truck to its preset distance using torque reduction, engine braking and service braking, maintaining a reduced cruising speed and reaccelerating to the set cruising speed when the slower vehicle clears or accelerates.
In stop-and-go traffic, if the vehicle in front stops, your truck will also come to a stop and hold indefinitely. If the vehicle ahead moves in under two seconds, the truck will resume moving at a safe following distance. ACC braking on stationary objects is now available at speeds of 35 mph or lower when the ACC system is on. If a stationary object, such as a disabled vehicle, is detected, the truck will smoothly reduce its speed to 0 mph.
