Abstract

Sixty drivers executed 1800 automotive transmission shifts from DRIVE to PARK. These shifts were performed in a total of six vehicles. Among analoq data recorded during each shift are longitudinal (pull) and rotational forces and rotational position of the lever. Analysis reveals that drivers typically impact the mechanical stop associated with PARK position with approximately one and one-half times the minimum force required to complete the shift. Shifts to PARK are completed in an average of 0.58 seconds, and an additional 0.83 seconds is spent continuing to apply force to the lever after PARK position is achieved. Most (80%) shifts are executed without regard for intervening detents. Those drivers who show hesitation in movement typically hesitate for 50 milliseconds. Whether a driver shifts continuously or with shortduration hesitation appears to be driver style or insert plate impact, independent of vehicle.
