Detroit is expanding on its Detroit Assurance suite of safety systems, adding several new features that are described as industry-first capabilities.
Active speed intervention (ASI) will trigger visual and auditory warnings if a truck exceeds a posted limit, and depending how fast the truck is traveling the system will even de-throttle the engine for two seconds, adjust the adaptive cruise control to the posted limit, or cancel adaptive cruise control.
Active lane assist (ALA) with auto stop, available exclusively on the Freightliner Cascadia, will actively apply the brakes rather than letting the truck roll to a stop if a driver is incapacitated or their hands are off the steering wheel for more than 60 seconds. Lane keep assist (LKA) will keep the vehicle centered in the lane while this happens. And once the truck comes to a stop, the doors will unlock and interior lights will flash an SOS to alert other motorists that help is needed.
Rounding out the updates is the brake hold mode, which reduced the need for a driver to continually push down on the brake pedal during prolonged periods at a standstill. The brake remains activated even if the driver’s foot slips off the pedal. Tapping the brake pedal or pressing the accelerator starts the truck moving again.
