SAE J985 Vision Factor Considerations in Rearview Mirror Design

The design and location of rear viewing mirrors or systems, and the presentation of the rear view to the driver can be best achieved if the designer and the engineer have adequate references available on the physiological functions of head and eye movements and on the perceptual capabilities of the human visual system. SAE J985 provides information and charts for this purpose, of which Velvac uses to help design intuitive vision systems to help make operating commercial vehicles safer. To read this standard, please visit the SAE website.

TMC Mirror Positioning and Aiming Guidelines

This recommended practice (RP) by the Technology Maintenance Council (TMC) provides mirror positioning and aiming guidelines. It states that (1) mirrors must be mounted so that the inner edge of the mirror is at least one inch outside of the widest part of the truck and trailer, and that the FOV of primary mirrors should in no way be obstructed by any part of the truck; (2) convex mirrors should be mounted and aimed to show traffic in adjacent lanes and view of trailer and wheels of trailer; (3) fender mirrors need to be mounted on the hood or fender of the cab in such a way that vibration of the mirrors is at a minimum; and (4) a typical trailer forms a 68° angle from the truck when making a 90° turn; therefore, the convex mirrors should be aimed so that no less than 70° can be seen outward from an imaginary line bisecting the cab of the truck. Velvac visions systems comply to these recommended practices to help ensure a safe driving environment in and around commercial vehicles. Visit TMC's website for more information related to this RP.
