NEXT OFFICE ACTION: DETAILED ACTION
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Buckland (U.S. Pat. NO. 10,895,197) in view of Shamoto (U.S. Pub. No. 2010/0250042).
Regarding claims 1, 9 and 17, Buckland discloses a computer-implemented (14 is the computer with 16 being the sensors and 81 being the actuators) method that, when executed by data processing hardware of a motor vehicle including a turbocharger having a turbine, causes the data processing hardware to perform operations comprising:

calculating a vehicle dynamic score (construed as a determination of accelerating, slowing, or maintaining) based on the plurality of vehicle performance parameter inputs (206 and 208);
Note: as per applicants specification ¶46 this is simply a determination that the vehicle is in a “dynamic operating state” which will be understood as not being in steady state.
Note: the determination of a dynamic score is only “based on” the plurality of parameters which only requires using one of the plurality in order to be satisfied.

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 (212).
Buckland does not disclose the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, and accelerator pedal position accumulation.
Shamoto, which deals in vehicle control, teaches the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, and accelerator pedal position accumulation (¶77 which discloses an integration of the pedal overtime which is rate data).
It would have been obvious to one having ordinary skill in the art at the time the invention was made to have modified Buckland with the manipulation of data of Shamoto because this allows for control of the battery (¶64).

Regarding claim 5 and 13 which depends from claim 1 and 9 respectively, Buckland discloses wherein the one or more outputs of the vehicle include an air intake rate (wastegate option addressed), a fuel intake rate (wastegate option addressed), a wastegate actuator output (212 adjusts the wastegate), and a camshaft phaser output (wastegate option addressed).
Regarding claim 6 and 14 which depends from claim 1 and 9 respectively, Buckland discloses wherein the operation of instructing one or more outputs of the vehicle to transition to a dynamic mode occurs while the accelerator pedal is in the overrun position (212 is due to 208 which is construed as the overrun position).
Regarding claim 8 and 16 which depends from claim 7 and 15 respectively, Buckland discloses wherein the one or more vehicle performance parameter inputs includes brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection (accelerator pedal position option addressed).
Regarding claim 21 which depends from claim 17, Shamoto discloses wherein the plurality vehicle of vehicle performance parameter inputs includes brake pedal position (84), braking force (¶65), vehicle lateral force (¶65 the torque request result in lateral forces), vehicle longitudinal force (¶65 the torque request result in lateral forces which can be a longitudinal force), driver selected vehicle mode (drive, reverse, park), engine speed (Ne) vehicle speed (88), and transmission gear selection (¶38).
