Abstract:
A vehicle comprising:a drivetrain including an air intake passage having a throttle valve rotatably coupled therein, said throttle valve being positionable between a first rotational position and a second rotational position, an internal combustion engine in fluid communication with said air intake passage, said internal combustion engine having a first output shaft, and a transmission operatively coupled to said first output shaft, said transmission having a second output shaft; and a control system for managing a torque of said drivetrain, said control system including a first sensor operable to provide a throttle position signal indicative of a rotational position of said throttle valve, a second sensor operable to provide a transmission speed signal indicative of a rotational speed of said second output shaft, and a controller responsive to said throttle position signal and said transmission speed signal to generate an engine speed limit signal as an indication of a maximum rotational speed of said first output shaft.
