Abstract
A vehicle launch control technique includes obtaining a desired launch torque curve and a desired launch speed, performing a pre-staging procedure including generating a torque reserve for a powertrain, in response to paddle shifters being a first configuration and accelerator and brake pedals being fully depressed and then controlling vehicle positioning/movement in response to driver manipulation of the brake pedal, performing a staging procedure including (a) increasing the torque reserve, (b) activating a trans brake feature to hold the vehicle stationary, and (c) increasing a speed of the powertrain to the desired launch speed, in response to (i) the paddle shifters in a different second configuration and (ii) fully releasing the brake pedal, and after the staging procedure and in response to the paddle shifters being in a different third configuration, executing a vehicle launch procedure by depleting the torque reserve according to the desired launch torque curve.
