1 Scope
This document describes the type, layout, location, and feedback display of available electro-mechanical and electronic transmission gear shifters found in passenger cars (including sport utility vehicles and light trucks) and in
commercial vehicles (including heavy trucks and buses). The transmission gear shifters are located on the steering column, instrument panel, floor and centre consoles. Specifically, this document addresses shift by-wire electro-mechanical selectors
that adapt the control of vehicle movement according to road conditions and personal
preference. Conventional mechanical shifters are also referenced so correspondence between traditional linear P, R, N, D, L, M/S
control types, layouts, locations and direction of control motions and electro-mechanical/electronic
transmission gear shifters (simply, e-shifters) can be established.
This document is based on observations and survey results described in Annexes A and B for passenger cars and commercial vehicles respectively. The results are independent
of vehicle propulsion systems and define the layout, spatial orientation and control
movement patterns for the following drive functions:
drive (D=forward movement),
reverse (R=rearward movement),
park (P=stationary),
