Assignee: BOMBARDIER RECREATIONAL PRODUCTS INC.
Field: Transport (Mechanical engineering)
Classification: CPC B  F  Y | IPC B  F

Claim 16:
17. A vehicle comprising:
a frame;
at least two ground engaging members connected to the frame;
a braking system operatively connected to at least one of the at least two ground engaging members;
at least one seat connected to the frame;
an engine supported by the frame;
a turbocharger operatively connected to the engine;
a controller communicatively connected to the engine; and
an accelerator communicatively connected to the controller,
the controller being configured to perform the steps of:
controlling an engine of the vehicle according to a first control strategy;
receiving a mode indication indicating that an operator of the vehicle has selected a launch mode for accelerating the vehicle;
in response to receiving the mode indication, controlling the engine according to a second control strategy;
while controlling the engine according to the second control strategy, determining an accelerator position of an accelerator of the vehicle;
in response to the accelerator position being greater than zero, controlling 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 an indication to end control by the second control strategy; and
in response to receiving the indication, controlling the engine according to the first control strategy,
controlling the engine according to the first control strategy with the braking system having been released 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.
