Fast Off Recognition
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
Fast off recognition is activated when the TCM detects that the driver has released the accelerator pedal quickly. This is detected by the TCM monitoring for a high level of negative pedal angle from ECM signals on the high speed CAN Powertrain systems bus. If this condition is detected, the TCM holds the current gear ratio to allow the driver to complete the maneuver without the need for a downshift. The mode can remain active for a predetermined length of time or if the driving style remains passive.
Fast off recognition mode assists vehicle stability and is used in conjunction with a lateral acceleration input during cornering to maintain the current gear until the corner is negotiated.
