Abstract
A driver controllable low speed mode for a stop/start technology-equipped vehicle. The vehicle comprises an internal combustion engine with stop/start technology having an engine controller, a transmission connected to the internal combustion engine, and a shifter connected to the transmission and the engine controller. The shifter is operable to place the transmission into one of a plurality of operating modes, the operating modes including at least a low speed mode wherein stop/start technology is disabled. The engine controller is operable to detect vehicle operation above a speed or acceleration threshold and cause an audible chime or message to be played or a visual cue displayed to prompt the driver to deactivate the low speed mode. The engine controller is further operable to detect a sustained acceleration attempt when the transmission is in low speed mode and to disable low speed mode for a predetermined period of time upon this detection.
