1. An apparatus for controlling operation of an internal combustion engine, comprising:
- a conditions module configured to determine an out-of-gear condition of the internal combustion engine; and
a permission module configured to allow a speed of the internal combustion engine to exceed a maximum engine speed limit if the determined out-of-gear condition meets a threshold, and prevent the speed of the internal combustion engine from exceeding the maximum engine speed limit if the determined out-of-gear condition does not meet the threshold.

Abstract
According to one embodiment, an apparatus for controlling operation of an internal combustion engine includes a conditions module that is configured to determine an out-of-gear condition of the internal combustion engine. The apparatus also includes a permission module that is configured to allow a speed of the internal combustion engine to exceed a maximum engine speed limit if the determined out-of-gear condition meets a threshold, and prevent the speed of the internal combustion engine from exceeding the maximum engine speed limit if the determined out-of-gear condition does not meet the threshold.

11. An internal combustion engine system, comprising:
-
an internal combustion engine comprising an engine output shaft; a transmission clutch configured to selectively couple the engine output shaft to a transmission input shaft and decouple the engine output shaft from the transmission input shaft; and a controller comprising a predetermined torque-speed map defining a first operating region for engine speeds below a maximum engine speed and a second operating region for engine speeds above the maximum engine speed, wherein operation of the internal combustion engine within the second operating region is allowed only when the transmission input shaft is selectively decoupled from the engine output shaft. - View Dependent Claims (12, 13, 14, 15)

16. A method for controlling operation of an internal combustion engine system, comprising:
-
determining whether the internal combustion engine system is out-of-gear; providing an engine operation map comprising a high speed region; allowing access to the high speed region when the internal combustion system is out-of-gear; and preventing access to the high speed region when the internal combustion system is not out-of-gear. - View Dependent Claims (17, 18, 19, 20)
