System and method for improving turbocharged engine driver torque response

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• receiving an accelerator pedal position input indicating that a vehicle accelerator pedal has moved to an overrun position;
• receiving a plurality of vehicle performance parameter inputs each corresponding to a measured vehicle performance parameter, the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, accelerator pedal position accumulation, brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection;
• calculating a vehicle dynamic score based on the plurality of vehicle performance parameter inputs;
• determining a target boost profile based on the calculated vehicle dynamic score exceeds a threshold vehicle dynamic score;
• and
• instructing one or more outputs of the vehicle to transition to a dynamic mode to generate an increased turbine power based on the target boost profile.
