1. A method for accelerating a vehicle from rest, the method comprising:
controlling, by a controller, an engine of the vehicle according to a first control strategy;
receiving, from a mode input by the controller, a mode indication indicating that an operator of the vehicle has selected a launch control mode for accelerating the vehicle;
in response to receiving at least the mode indication, controlling the engine, by the controller, according to a second control strategy;
while controlling the engine according to the second control strategy, determining, by the controller, an accelerator position of an accelerator of the vehicle;
in response to the accelerator position being greater than zero, controlling, by the controller, the engine to:
increase, according to the accelerator position, an opening of a throttle valve of the engine, and
control operational conditions of the engine to limit engine torque output;
while controlling the engine according to the second control strategy, receiving, by the controller, an indication to end control by the second control strategy; and
in response to receiving the indication, controlling the engine, by the controller, according to the first control strategy,
controlling the engine according to the first control strategy in response to the indication causing the vehicle to accelerate from rest,
a first rate of acceleration from rest of the vehicle being greater than a second rate of acceleration from rest of the vehicle for corresponding changes in accelerator position,
the first rate of acceleration corresponding to the vehicle accelerating from rest after sequentially controlling the engine according to the first and second control strategies;
the second rate of acceleration corresponding to the vehicle accelerating from rest by controlling the engine according to the first control strategy without previously controlling the engine according to the second control strategy.
