Volvo Trucks has been de­vel­op­ing truck-platooning tech­nol­ogy called Co­op­er­a­tive Adap­tive Cruise Con­trol, and the au­tomaker took to the North Carolina Turn­pike to show how the syn­ergy of the tech works be­tween a truck man­u­fac­turer and trans­port com­pany (in this case, FedEx). Ac­cord­ing to Volvo Trucks, “The ‘pla­toon’ con­sisted of three trained, pro­fes­sional truck driv­ers in Volvo VNL trac­tors, each of them pulling dou­ble 28-foot trail­ers. Through CACC, a wire­less ve­hi­cleto-ve­hi­cle com­mu­ni­ca­tion tech­nol­ogy, the trac­tors and trail­ers re­mained in con­stant com­mu­ni­ca­tion. The trac­tors and trail­ers trav­eled at speeds of up to 62 mph while keep­ing a time gap of 1.5 sec­onds, main­tain­ing a closer dis­tance than what is typ­i­cal for on­high­way trac­tors. Staged and un­planned ve­hi­cle cut-ins demon­strated how the tech­nol­ogy han­dles com­mon traf­fic sit­u­a­tions. The ve­hi­cle-to-ve­hi­cle com­mu­ni­ca­tion sys­tem helps re­duce the re­ac­tion time for brak­ing and en­ables ve­hi­cles to fol­low closer, au­to­mat­i­cally match­ing each other’s speed and brak­ing. The ad­vanced tech­nol­ogy is meant to serve as an aid—not a re­place­ment—for skilled pro­fes­sional truck driv­ers. When trucks can drive closely be­hind one an­other, fuel ef­fi­ciency is im­proved as a re­sult of re­duced drag.”
