ABSTRACT:
An actuation enhancement for an automated vehicle inter-axle differential (IAD) locking system. The vehicle having an engine and a tandem drive axle. The IAD actuation enhancement locking system comprises a rotating sliding clutch and a rotating side helical gear, which are capable of an engagement mode and a disengagement mode, a microprocessor, and an electrical connection between the microprocessor and an engine electronic control unit. When the sliding clutch and the helical gear are placed in the engagement mode or are placed in the disengagement mode, the microprocessor momentarily communicates a data link message to the engine electronic control unit to break engine torque, to facilitate engagement or disengagement of the sliding clutch and the helical gear.
