Calculation and Measurement of the Time to Complete In-Vehicle Navigation and Route Guidance Tasks
This Recommended Practice can apply to both Original Equipment Manufacturer and Aftermarket route-guidance and navigation system functions for passenger vehicles. The methods apply only to the presentation of visual information and the use of manual control inputs to accomplish a navigation or route guidance task. They do not apply to visual monitoring tasks which do not require a manual control input, such as route following. Voice-activated controls or passenger operation of controls are also excluded.
Rationale: This revised version of SAE J2365 addresses the calculation and measurement of the time needed to accomplish in-vehicle visual manual tasks. It was prepared and adopted in 2015. One goal of the review and revision at that time was to revise SAE J2365 to include useful material from SAE J2364, “Navigation and Route Guidance Function Accessibility While Driving,” including the “Static Method.” In this way both a method for predicting in-vehicle secondary task times, and a procedure for measuring such task times (originally in SAE J2364) are presented in one integrated document. SAE J2364 had previously been stabilized and can be accessed for archival purposes. Another goal of the 2015 revision of SAE J2365 was to include useful material from SAE J2678, “Navigation and Route Guidance Function Accessibility While Driving Rationale,” which was the original rationale for SAE J2364. At the conclusion of the SAE J2365 revision effort in 2015, J2678 was effectively superseded by this new version of SAE J2365. Of the 3 original Recommended Practices (SAE J2364, SAE J2365, and SAE J2678), SAE J2365 results as a working and current Recommended Practice.
