Detroit announced it added new features to its Detroit Assurance suite of safety systems for the Freightliner Cascadia and Western Star 49X models spec’d with a Detroit powertrain.

The features are intended to reduce driver strain, fatigue and speed-related accidents, according to Detroit, a unit of Daimler Trucks North America.

They include:

Active Speed Intervention: If the truck exceeds the posted speed limit, ASI issues visual and auditory warnings to actively alert the driver. Once the warning is issued and depending on how far above the truck is over the speed limit, ASI will go into effect and de-throttle the engine for two seconds, adjust Adaptive Cruise Control to the posted speed limit, or cancel ACC.

Active Lane Assist with Auto Stop: exclusively available with the Freightliner Cascadia, ALA with Auto Stop actively brakes the truck to a safe stop rather than letting the truck roll to a stop in case of an incapacitated driver or if the driver’s hands are off the steering wheel for more than 60 seconds. When ALA’s Auto Stop function activates, Lane Keep Assist keeps the truck centered in its lane while the truck safely and gradually brakes, all the way down to 0 mph. After coming to a stop, the vehicle doors automatically unlock and the interior lights flash in an SOS sequence, alerting other motorists that assistance is required.

Brake Hold Mode: After coming to a stop, the driver further presses the brake pedal to activate the Brake Hold Mode function, reducing the need for the driver to continually press the brake pedal down in prolonged periods of standstill. The brake will not get deactivated if the driver’s foot is removed from the brake pedal due to fatigue or slippage. Tapping the brake pedal or pressing the accelerator starts moving the truck again.
